General Data, Allison

Hard disk drive-series automatic transmissions take six frontward speeds and one reverse speed. Run into Fig. fourteen.9 . These transmissions accept electronic shift controls that can be programmed to allow the utilize of different numbers of geared speeds. For case, the manual can be programmed to operate as a 4-speed, five-speed, or 6-speed unit in the "main" shift mode. If needed, a "secondary" shift fashion can be programmed to provide another shift configuration to optimize vehicle use nether different operating conditions. To activate a secondary shift way, or other special office programmed into the electronic control unit of measurement (ECU), depress the Way push button. "Mode On" is displayed in the indicator console just in a higher place the push buttons. A label but above the Mode push button identifies the special function.

NOTE: Each fourth dimension a push push is depressed on the shift selector, a curt beep will be heard. This indicates that the ECU has received input to alter functioning.

Functioning Tips, Allison

Never shift from neutral (North) to drive (D) or reverse (R) at engine speeds higher up idle. The vehicle volition lurch forward or backward, which could cause belongings damage and personal injury.

The engine should never be operated for more than xxx seconds at full throttle with the transmission in gear and the output stalled. Prolonged operation of this type will overheat the transmission fluid and volition consequence in severe impairment to the transmission.

Do not allow the vehicle to coast in neutral. This can effect in severe manual damage. Also, no engine braking is available.

The following tips highlight imortant operation principles.

Start the engine, then check the digital display on the "button shift selector." Under "Select" at the top of the unit of measurement, the display should always evidence the "primary" shift way. Under "Monitor," the gear the transmission is in should be displayed.

Employ reverse (R) to back the vehicle. Completely stop the vehicle before shifting from a forward gear to reverse, or from opposite to forward. There is only one contrary gear.

Select drive (D) for all normal driving weather condition. The vehicle will start out in 1st gear, and as speed increases, the transmission volition upshift through each gear automatically. Equally the vehicle slows down, the transmission will downshift to the correct gear automatically.

The pressure of your foot on the accelerator pedal influences the automatic shifting. When the pedal is fully depressed, the manual volition automatically upshift near the governed speed of the engine. A partially depressed position of the pedal will cause the upshifts to occur at a lower engine speed.

Occasionally the road, load, or traffic conditions make information technology desirable to restrict the automatic shifting to a lower range. The lower the gear range, the greater the engine braking ability.

Employ the upward or down pointer buttons on the shift selector to reach the desired gear. The "Select" indicator will display your pick, and the "Monitor" indicator volition show the selected gear one time it is reached. In the lower gear ranges, the transmission will non upshift above the highest gear selected unless the engine governed speed is exceeded.

Use neutral (North) and apply the parking brake when the vehicle is parked with the engine running.

Freightliner SmartShift Shift Command

General Information, SmartShift

The SmartShift transmission control is an electronic transmission control device. It is installed with the post-obit transmissions:

Eaton Fuller UltraShift™ PLUS

Information technology replaces the typical floor-mounted shift lever or dash-mounted button button control.

SmartShift accepts driver requests for transmission functions and transmits them through hard wiring to the manual control unit (TCU). SmartShift is a true shift-by-wire system.

SmartShift offers ii main advantages over conventional manual command devices. Without a floor-mounted shift command, usable cab space is increased. The SmartShift command mounts to the correct-hand side of the steering column and is operated by the fingers of the driver's right mitt, allowing both hands to remain on the steering bicycle.

A two-position slide switch is mounted on the body of the control lever merely before the paddle widens out. The slide switch allows the commuter to choose automated (AUTO) or manual (MAN) mode. Run across Fig. xiv.i .

In Automobile mode, gears shift automatically, without driver interaction. Manual gearshifts are accomplished past a momentary pull or push button on the control in the plane perpendicular to the steering wheel. Pull upward (toward yous) on the control to upshift and push down (away from you) to downshift. The control is bound-loaded and returns to mid-position when released later on an upshift or downshift.

For Eaton Fuller UltraShift PLUS and AutoShift transmissions, a iv-position (R, North, D, L) selector switch is located at the stop of the lever. See Fig. fourteen.1 .

To upshift manually, pull the lever up (towards you). To downshift manually, button the lever downward (away from you).

Embedded in the selector switch is a small neutral lock push button to forbid accidental shifts into gear from neutral. Whatever time you shift through North, press down on the neutral lock button to move the switch from neutral (N) to another gear, such as drive (D), low (L), or reverse (R). When shifting to North, it is non necessary to press the neutral lock button.

Eaton Fuller UltraShift PLUS Automated Transmissions

Eaton Fuller UltraShift PLUS automated transmissions use shift pick software and electrical clutch actuation; a clutch pedal is not needed to operate the vehicle. These transmissions use the 4-position SmartShift control (see Fig. 14.1 ) on the steering column to select mode, management, neutral, low, and to make manual shifts. To know what gear the manual is in, run across the current gear indicator on the dash. Forward shifts tin exist fabricated either manually or automatically.

Power Up

NOTE: Engine cranking is delayed until the transmission ability-up is complete and the gear display shows a solid "Northward".

1.

With the parking restriction fix, turn the ignition switch to the ON position.

Notation: If the service brake is not applied while selecting a starting gear, the initial start gear will non be found and the driver will demand to select Neutral and press the service brake while selecting the desired mode.

four.

Select the desired mode and starting gear. (Inappropriate start gear selections are ignored to avoid dissentious the manual.)

five.

Release the parking brake.

six.

Release the service restriction and apply the accelerator.

Power Downward

1.

Select Neutral on the shift control.

Notation: If the gear display does not show a solid "N", neutral has not even so been obtained. Neutral should always be reached before powering downward an UltraShift PLUS, except in cases of emergency.

3.

Turn off the ignition, and shut down the engine.

Reverse (R)

Note: If attempting to select a non-Neutral mode without applying the service brakes, the transmission will not shift into gear. To shift into gear, select Neutral, apply the service brakes, and select the desired mode again. As well, the vehicle will not appoint reverse above ii mph (3 km/h).

Opposite (R) is at the upper terminate of the four-position selector switch located at the finish of the SmartShift control. To select R, press in the neutral lock button and move the selector switch to the position above neutral. The default Reverse gear is engaged.

Avoid launching the vehicle in loftier range. Launching the vehicle in high range increases the likelihood of clutch abuse and could be detrimental to clutch life.

Automated Mode (Motorcar)

In automatic drive style (AUTO), upshifts and downshifts are made by the UltraShift PLUS without commuter intervention. Press in the neutral lock button, move the selector switch to Drive (D), and press downward on the throttle pedal. The transmission will shift automatically.

Notation: If attempting to select a non-Neutral way without applying the service brakes, the manual will non shift into gear. To shift into gear, select Neutral, apply the service brakes, and select the desired way once more.

In Drive, the start gear is automatically selected. The selected start gear can vary depending on several vehicle inputs such as load, grade, and axle/transmission ratio. The start gear can be changed using the SmartShift command, provided the selected gear would allow the vehicle to launch without damaging the manual. If the start gear is inverse using the SmartShift command, information technology will be the default until the vehicle is powered down or the selection is changed over again manually.

Important: Prior to ascending a steep grade, either reduce the default start gear past one (using the SmartShift command) or use full throttle for the elapsing of the course so the vehicle maintains the proper engine and vehicle speed during the entire grade.

In Drive, the manual automatically performs upshifts and downshifts. However, when the manual is nearly the shift betoken, the shift tin can be forced using the upshift or downshift role of the SmartShift command.

Notation: The transmission may deny a shift while ascending or descending a grade if the load of the vehicle and grade of the terrain in combination with the drivetrain ratio and engine torque fall outside of the acceptable range to perform a shift. If the shift is denied, a tone will sound.

Manual Fashion (MAN)

In manual mode (MAN), the commuter selects upshifts and downshifts instead of letting the UltraShift PLUS select them automatically. Manual shifting may be helpful when traversing a piece of work site, railroad tracks, or steep grades, for case. To drive forward, press in the neutral lock button, move the selector switch to Drive (D), and press down on the throttle pedal. To shift up, pull the lever up (towards you); to shift downward, button the lever down (away from you lot). The system holds the current gear unless a shift is requested or if the system initiates a transmission mode override.

Annotation: The transmission may deny a shift while ascending or descending a grade if the load of the vehicle and grade of the terrain in combination with the drivetrain ratio and engine torque fall exterior of the adequate range to perform a shift. If the shift is denied, a tone volition audio.

NOTE: If attempting to select a not-Neutral mode without applying the service brakes, the transmission will not shift into gear. To shift into gear, select Neutral, utilise the service brakes, and select the desired manner again.

Manual Mode Override

The system is equipped with a manual manner override function. If the vehicle is being "dorsum driven" (for example, descending a course and vehicle speed exceeds engine speed) and the engine speed is excessively high, the organisation will upshift automatically. Also, if the outset gear is changed and it causes the engine to lug at takeoff, the organisation volition override the current position and select the best available gear.

Low (L)

Low (50) is at the lower cease of the four-position selector switch located at the stop of the SmartShift control. Utilise Low when wanting to maximize engine braking and minimize the employ of the brake pedal—for case, when driving down long grades or when coming to a terminate. To select Low, press in the neutral lock push and motion the selector switch to the 50 position. The lowest bachelor start gear will exist selected (the starting gear cannot exist changed in Low).

If Low is selected while moving, the manual will not upshift (unless the system initiates a Low override). The system will downshift at the earliest opportunity to provide maximum engine braking.

Note: If attempting to select a non-Neutral way without applying the service brakes, the transmission will non shift into gear. To shift into gear, select Neutral, apply the service brakes, and select the desired mode over again.

Depression Override

The organization is equipped with a Low override function. If the vehicle is being "back driven" (for example, descending a grade and vehicle speed exceeds engine speed) and the engine speed is excessively loftier, the system will upshift automatically. As well, if the start gear is changed and it causes the engine to lug at takeoff, the system will override the current position and upshift.

Clutch Abuse Protection

Although a vehicle equipped with an UltraShift PLUS uses an automated clutch, the clutch can notwithstanding overheat and sideslip with improper utilize. The clutch abuse protection characteristic helps protect the clutch if the automated clutch starts to overheat. When the clutch abuse protection characteristic initiates and sounds a alert tone, full clutch actuation must exist completed rapidly. If it is not completed rapidly enough, the arrangement will either open the clutch (if the throttle pedal is not being pressed) or close the clutch (if the throttle pedal is being pressed). If the abuse continues, the organisation volition open the clutch and have away throttle control briefly to permit the clutch to absurd downwards.

To protect the clutch:

Select the everyman possible start gear for the application.

Use Creep Mode when appropriate.

Use the service brakes and the Hill Commencement Aid when launching on a course.

Minimize the fourth dimension it takes to engage the clutch from rest.

Do not use the throttle to hold the vehicle on a grade; use the service brakes.

Exercise not use the throttle to stop roll back on an incline after Loma Start Aid disengages; use the service brakes, and then relaunch.

Exercise non continually first and stop, particularly when loaded; utilize a lower gear or Creep Way.

Creep Mode

The Creep Mode function allows the vehicle to maintain a constant speed at engine idle without the driver holding the throttle pedal position. This mode is useful for very low-speed maneuvering and applications where steady vehicle speed is required. The vehicle speed is determined by the selected gear ratio operating at governed low engine idle speed. Whatsoever available gear may be selected, though the transmission volition downshift or exit Pitter-patter Mode to preclude stalling if the engine lugs due to load conditions.

By default, Creep Mode tin can be activated while in Manual Mode or Low. Eaton'south ServiceRanger diagnostic software can be used to enable Creep Mode in Automatic Mode and/or Opposite.

Engaging Creep Manner

To appoint Creep Mode:

one.

Select Low or Manual Mode and the desired gear (while stopped or moving).

2.

Employ the throttle pedal to accelerate the vehicle until the clutch is closed (engaged).

iii.

Release the throttle pedal. The vehicle will continue moving at governed low engine idle speed.

Exiting Creep Style

To exit Creep Way, apply the throttle pedal to advance temporarily, or select a college gear in Manual Fashion. (Creep Mode tin exist resumed in the selected gear by releasing the throttle pedal.)

Note: The transmission will exit Pitter-patter Manner if the engine lugs 150 rpm below the governed depression engine idle speed. In this instance, a lower gear should be selected if available.

Hill First Help

UltraShift PLUS transmissions are equipped with a Hill Offset Help (HSA) feature to prevent the vehicle from rolling while on grades steeper than 3% and allow for a controlled launch. A class sensor is used to determine when to engage the feature.

HSA is "on" past default. It can be turned off by pressing and releasing the override switch on the nuance. HSA will plough dorsum on after the first successful launch.

When the vehicle is stopped on a grade greater than 3% and in a forward mode or opposite, depress the service brakes so release them. The vehicle volition begin to move after iii seconds, and the clutch will perform partial engagements to slow the vehicle motion. Either step on the brake or apply the throttle to go on negotiating the grade.

Engine Overspeed Protection

The system will upshift if necessary to forbid engine overspeed in Drive, Manual, and Low.

Shuttle Shifting

Shuttle shifting from contrary to any forward mode is merely allowed if the vehicle speed is approximately zero.

Auto Beginning Gear Selection and Override

The UltraShift PLUS system uses various inputs to automatically select the best start gear in Bulldoze and Manual. This selection can be changed using the SmartShift control; however, if the selection requested could cause damage or engine lugging, the request will exist denied and a tone will sound.

Skip Shifting

When appropriate, the UltraShift PLUS organisation may skip shift in Drive. When prevailing conditions like load and grade allow, skip shifts can be performed in Transmission mode using the SmartShift command.

Auto Neutral

The UltraShift PLUS system will automatically shift to neutral if the vehicle is left in Drive and the parking brake is set. "AN" will prove on the gear display. To re-engage the transmission, select Neutral and so either Bulldoze or Reverse on the shift control (information technology volition re-appoint regardless of whether the parking brake is released).

Automatic Traction Control

The UltraShift PLUS system requires the Automatic Traction Command (ATC) option to be enabled when driving in soft soil/sand to prevent wheel slippage and shifting issues. The ATC system has two modes: "normal" (for sand and loose road surface) and a mud/snow setting.

ATC Normal Mode

In normal mode, the organisation volition appoint the brakes on the wheel or side that the wheel slip is occurring to help the vehicle proceeds traction. The point at which the traction control will activate the braking system increases with throttle: low throttle allows the system to restriction the wheels earlier; heavy/full throttle raises the point of the acceptable wheel slip.

Adhere to the following points when driving in ATC normal manner:

If using Automatic way in soft soil and/or sand, maintain the engine speed between thousand and 1300 rpm to prevent unnecessary upshifting.

If using Manual mode in soft soil and/or sand, do non attempt an upshift and try to maintain the electric current gear.

If the vehicle comes to a stop in the sand it may be necessary to back up prior to attempting forrard move.

ATC Mud/Snow Mode

To select the mud/snow style, depress the ATC switch (see Chapter 5 ). This mode raises the wheel slip speed that is allowed before the traction command activates. The point at which the traction control will actuate the braking system increases with throttle: low throttle allows the system to restriction the wheels earlier; heavy/total throttle raises the bespeak of the adequate wheel slip.

Load-Based Shifting

The UltraShift PLUS system is adaptive and volition change the shift points based on grade, engine RPM, throttle position, and vehicle load. After changing loads or powering up, the system needs to relearn these inputs for the first few shifts to make the proper adjustments.

Benumbed

When coasting to a stop on level terrain, the UltraShift PLUS organization may not downshift into the lower gears. It will select a gear afterward the throttle is applied.

Ultrashift PLUS Diagnostics

System Problem

In the issue of a trouble, do the following steps.

1.

Note the driving weather at the time the problem occurred.

2.

Record the status of the manual at the fourth dimension of the trouble (AUTO or Human mode, gear setting R, Northward, D, or L, electric current gear, engine speed, etc.)

iii.

Reset the arrangement, using the procedure below.

Reset Procedure

Transmission operation can sometimes be restored by doing the following reset procedure:

1.

Stop the vehicle when it is condom to exercise so. Set the parking brake.

2.

Place the selector switch in neutral and turn off the ignition.

3.

Cheque all harness connectors as described in Chapter xx .

iv.

Await at to the lowest degree two minutes with the engine shut down.

If the problem continues, contact an authorized Freightliner or Eaton service facility.

Eaton Fuller AutoShift Automated Transmissions

Refer to the Eaton website for boosted information,www.roadranger.com.

General Information, AutoShift

RT/RTO Models

Eaton Fuller AutoShift transmissions have 10 or 18 forward speeds and two contrary speeds. The driver must use the clutch to start and stop the vehicle.

The commuter does non need to intermission torque or increase or decrease engine speed to synchronize the shift. The transmission signals the engine controller when to pause torque and the engine controller automatically increases or decreases engine speed. When engine speed is correct, the transmission engages the next gear and signals the engine controller to resume operation.

The AutoShift system consists of the following components:

The SmartShift command paddle on the steering cavalcade. Meet Fig. 14.1 .

The gear brandish module mounted on the dashboard indicates the current gear position or transmission status. The display too flashes the adjacent gear to be engaged while the transmission is in neutral during a gear change. Meet Fig. xiv.2 .

The shifter mechanism performs shifts at the front portion of the transmission. It preselects the shift to neutral and completes the gear change subsequently driver input.

The Electronic Control Unit (ECU) includes two controllers: a manual ECU and a arrangement ECU. The transmission ECU controls all transmission shift functions and the system ECU manages all vehicle interfaces for manual shift functions.

An electronic range valve, controlled by the manual ECU, is used to perform range shifts.

Operation, AutoShift with SmartShift

Automatic and Manual Modes

A two-position slide switch (forward driving mode switch) is located most the end of the SmartShift control. See Fig. 14.1 . The switch positions are labelled MAN (manual shift way) and AUTO (automatic drive way).

Note: In automated drive manner, upshifts and downshifts require no commuter interaction. Move the selector switch to the drive (D) position, disengage the clutch to engage the gear selected, engage the clutch and bulldoze the vehicle. In manual shift mode, upshifts and downshifts crave either a pull upwards or push downward on the control.

Driver Bulletin Center

Gear data is presented to the driver via a LCD brandish on the dash. In automated bulldoze style, the number of the forward gear currently engaged appears continually on the message display screen when in drive (D). In transmission shift mode, the current gear is displayed until a new gear is requested. When neutral (Due north) is engaged, "N" volition announced on the message display screen. When reverse (R) is engaged, either "RL" or "RH" will appear on the bulletin display screen.

Of import: The data shown on the message display screen indicates the country of the transmission merely, non the state of the SmartShift control.

Neutral Position

Select neutral by sliding the selector switch to the "Northward" position.

Notation: Neutral is always available during operation. When in neutral, upshift and downshift requests are ignored. If the way selector switch is moved from neutral (N) to drive (D) while the vehicle is moving, the transmission will shift into a gear causing the engine to become to a high torque level, under the engine'south rated torque.

Selecting a Starting Gear

1.

In automatic manner, select drive (D) by sliding the selector switch down to the side by side position below the neutral position.

2.

Disengage the clutch to engage the gear selected. Appoint the clutch and drive the vehicle.

Changing the Default Starting Gear

To select a starting gear other than the default starting gear, follow the instructions below.

i.

Make sure the vehicle is stopped and in drive.

2.

In either automated or manual mode, pull upwards on the control (to increase), or push button downwardly (to decrease). Each pull up on the control increases the starting gear by one gear, simply no higher than fourth gear.

3.

The number of the gear selected volition flash on the message display screen until the driver engages the clutch. This gear volition exist stored in retention as the default starting gear until either a different starting gear is selected by the driver or the engine is close down.

Annotation: The transmission may also be programmed and so that it is non possible to select a starting gear other than the preprogrammed default starting gear.

Upshifting

NOTE: With the transmission in drive (D) in the automatic mode, upshifts require no driver interaction.

1.

With the transmission in bulldoze in the manual mode, request an upshift past pulling upward on the command. If the requested gear is available, the manual will upshift.

NOTE: A single, momentary pull upwardly on the command selects the next college gear when it is available. Two consecutive, momentary upward pulls will crusade a skip shift when the next two higher gears are bachelor and atmospheric condition are correct.

2.

To skip shift, move the command two times in less than 1/2 second. The number of the gear engaged will appear on the bulletin display screen.

Annotation: The Eaton Fuller AutoShift transmission is able to perform triple upshifts when the side by side three higher gears are bachelor and conditions are right. To triple-shift this transmission, move the command three times in less than 1/2 2nd.

If a requested gear is non available, an audible alarm volition sound and the gear display module will indicate that the gear is not available. An unavailable requested upshift is not stored in retentiveness. The upshift must be requested again.

Downshifting

Note: With the transmission in drive (D) in the automatic mode, downshifts crave no driver interaction.

1.

With the transmission in drive in the manual mode, request a downshift by pushing downward on the command. If the requested gear is bachelor, the transmission will downshift.

NOTE: A unmarried, momentary button downward on the control selects the next lower gear when information technology is bachelor. Two consecutive, momentary downwards pushes volition cause a skip shift, when the next 2 lower gears are bachelor and atmospheric condition are right.

ii.

To skip shift, motion the control two times in less than 1/2 2nd. The number of the gear engaged will announced on the bulletin brandish screen.

Note: The Eaton Fuller AutoShift transmission is able to perform triple downshifts when the adjacent three lower gears are available and atmospheric condition are correct. To triple shift this manual, move the control three times in less than 1/2 second.

If a requested gear is not available, an aural warning volition audio and the gear brandish module will bespeak that the requested gear is not available. Unlike upshifting, an unavailable requested downshift is stored in retentivity and the shift will be made when the gear is available. The time limit for this retentivity is a programmable parameter.

Kickoff-Up

one.

With the parking restriction applied, printing the clutch all the manner down to the floor.

three.

Check to make certain the transmission is in neutral.

4.

With the transmission in neutral, release the clutch.

Note: This allows the speed sensor on the input shaft to get a reading.

5.

Press down on the clutch again and release the parking restriction.

half dozen.

Select the desired starting gear.

Opposite

1.

To appoint reverse (R), slide the selector switch upward to the next position above the neutral position and disengage the clutch.

NOTE: AutoShift transmissions have a dual-range reverse. Opposite low (RL) is the default reverse gear.

2.

Select contrary high (RH) by pulling upward on the command.

NOTE: Opposite may be engaged beneath a programmable forward speed in guild to stone the vehicle. If reverse is selected above the programmed forwards speed, an audible warning will sound and a message indicating that the gear is not available will appear on the message display screen.

Low Gear Performance

Utilize depression (L) when descending steep hills and using pinch braking. Engine speed will exist increased by 200 rpm and shift points will be showtime by 200 rpm. The efficiency of the exhaust brake will be maximized.

Using the Clutch

Apply the clutch to outset and stop the vehicle.

Allison Automatic Transmissions

Refer to the Allison website for additional data,www.allisontransmission.com.

General Data, Allison

HD-series automatic transmissions have six forward speeds and one reverse speed. See Fig. fourteen.iii . These transmissions have electronic shift controls that can be programmed to allow the use of different numbers of geared speeds. For instance, the transmission can be programmed to operate equally a iv-speed, 5-speed, or vi-speed unit in the "main" shift manner. If needed, a "secondary" shift mode tin be programmed to provide another shift configuration to optimize vehicle use nether different operating conditions. To activate a secondary shift fashion, or other special function programmed into the electronic control unit (ECU), depress the Mode button. "Mode On" is displayed in the indicator panel merely above the push buttons. A label just above the Mode button identifies the special function.

Fig. 14.3, Allison Button Button Shift Selector

NOTE: Each fourth dimension a button is depressed on the shift selector, a short beep volition be heard. This indicates that the ECU has received input to modify performance.

Operation Tips, Allison

Never shift from neutral (Northward) to drive (D) or contrary (R) at engine speeds to a higher place idle. The vehicle volition lurch frontwards or backward, which could crusade property damage and personal injury.

The engine should never be operated for more than thirty seconds at full throttle with the transmission in gear and the output stalled. Prolonged operation of this type will overheat the transmission fluid and will issue in severe damage to the transmission.

Practise not allow the vehicle to coast in neutral. This tin can result in severe transmission damage. As well, no engine braking is available.

The post-obit tips highlight imortant operation principles.

Start the engine, and so bank check the digital brandish on the "push push button shift selector." Under "Select" at the top of the unit, the display should ever prove the "principal" shift way. Under "Monitor," the gear the transmission is in should be displayed.

Employ reverse (R) to back the vehicle. Completely stop the vehicle earlier shifting from a forward gear to reverse, or from contrary to forrad. There is only one contrary gear.

Select bulldoze (D) for all normal driving conditions. The vehicle volition start out in 1st gear, and as speed increases, the transmission volition upshift through each gear automatically. Equally the vehicle slows down, the transmission will downshift to the correct gear automatically.

The pressure of your pes on the accelerator pedal influences the automatic shifting. When the pedal is fully depressed, the transmission will automatically upshift almost the governed speed of the engine. A partially depressed position of the pedal will cause the upshifts to occur at a lower engine speed.

Occasionally the road, load, or traffic conditions make it desirable to restrict the automatic shifting to a lower range. The lower the gear range, the greater the engine braking power.

Apply the up or downwardly arrow buttons on the shift selector to reach the desired gear. The "Select" indicator will brandish your choice, and the "Monitor" indicator will show the selected gear once information technology is reached. In the lower gear ranges, the transmission will non upshift above the highest gear selected unless the engine governed speed is exceeded.

Use neutral (N) and apply the parking brake when the vehicle is parked with the engine running.
