STARTING AND OPERATING

171

The system requires that the ignition be in the

ON/RUN position or the engine running for all user

requested changes. When lowering the vehicle, all

of the doors must be closed. If a door is opened at

any time while the vehicle is lowering, the change

will not be completed until the open door(s) is

closed.
This system uses a lifting and lowering pattern

which keeps the headlights from incorrectly

shining into oncoming traffic. When raising the

vehicle, the rear of the vehicle will move up first

and then the front. When lowering the vehicle, the

front will move down first and then the rear.
After the engine is turned off, it may be noticed that

the air suspension system operates briefly; this is

normal. The system is correcting the position of the

vehicle to ensure a proper appearance.
To assist with changing a spare tire, the air

suspension system has a feature which allows the

automatic leveling to be disabled

page 237.

NOTE:



Default Ride Height:



Select Aero Height or Normal Ride Height as

the default for all vehicle speeds and oper

-

ation. This is the selected height that the

suspension will level for speed changes

(e.g. raising from Entry/Exit Height at speed,

lowering from Off-Road Height at speed,

etc.).



Default ride height can be changed by

manually adjusting the Air Suspension

switch to Normal Ride Height or Aero Ride

Height and staying in the selected height for

2.5 seconds. It will be stored as the default

ride height and the height will be main

-

tained until a new default ride height is

selected.

If equipped with a touchscreen radio, all enabling/

disabling of air suspension features must be done

through the radio

AXLE LOCK SYSTEM — IF EQUIPPED

This vehicle is equipped with an electronically

locking rear differential. When engaged, this

differential locks the axle shafts forcing the wheels

to spin at an equal rate. The locking of the rear

differential should only be engaged during

low-speed, extreme off-road situations where one

wheel is likely to not be in contact with the ground.

It is not recommended to drive the vehicle with the

differentials locked on pavement due to the

reduced ability to turn and speed limitations.

AXLE LOCK Button

The locking rear axle is controlled by the AXLE

LOCK button.
Under normal driving conditions, the rear axle

should be unlocked.
During the command to lock the rear axle, the

indicator light will flash until the axle is locked.

After the lock command has been successfully

executed, the light will remain on solid.
Operating in 4WD LOW the locker can be engaged

up to 40 mph (64 km/h) and will remain engaged

throughout the 4WD LOW speed range.

Operating the locker in 2WD, 4WD AUTO, and 4WD

LOCK/HIGH, the locker can be engaged up to

20 mph (32 km/h). While driving with the locker

engaged, if speed exceeds 25 mph (40 km/h), the

locker will automatically disengage, but will

automatically re-engage at 20 mph (32 km/h).

NOTE:

Left to right wheel speed difference may be

necessary to allow the rear axle to fully lock. If the

indicator light is flashing after selecting the rear

axle lock mode, drive the vehicle in a turn or on

loose gravel to expedite the locking action.
The axle locker could become torque locked due to

side to side loads on the rear axle. Driving slowly

while turning the steering wheel from a left hand

turn to a right hand turn or driving in REVERSE for

a short distance may be required to release the

torque lock and unlock the axles.
To unlock the rear axle, push the AXLE LOCK

button. The AXLE LOCK indicator light will go out

when the rear axle is unlocked.

CAUTION!



Do not lock the rear axle on hard surfaced

roads. The ability to steer the vehicle is

reduced and damage to the drivetrain may

occur when the axle is locked on hard

surfaced roads.



Do not try to lock the rear axle if the vehicle is

stuck and the tires are spinning. You can

damage drivetrain components. Lock the rear

axle before attempting situations or navi

-

gating terrain, which could possibly cause the

vehicle to become stuck.

STARTING AND OPERATING

LIMITED-SLIP DIFFERENTIAL —

IF EQUIPPED

The limited-slip differential provides additional

traction on snow, ice, mud, sand and gravel,

particularly when there is a difference between the

traction characteristics of the surface under the

right and left rear wheels. During normal driving

and cornering, the limited-slip unit performs

similarly to a conventional differential. On slippery

surfaces, however, the differential delivers more of

the driving effort to the rear wheel having the

better traction.
The limited-slip differential is especially helpful

during slippery driving conditions. With both rear

wheels on a slippery surface, a slight application of

the accelerator will supply maximum traction.

When starting with only one rear wheel on an

excessively slippery surface, slight momentary

application of the parking brake may be necessary

to gain maximum traction.

Care should be taken to avoid sudden

accelerations when both rear wheels are on a

slippery surface. This could cause both rear wheels

to spin, and allow the vehicle to slide sideways on

the crowned surface of a road or in a turn.

POWER STEERING

E

LECTRIC

P

OWER

S

TEERING

The electric power steering system will provide

increased vehicle response and ease of

maneuverability. The power steering system

adapts to different driving conditions.
If the steering icon is flashing, it indicates that the

vehicle needs to be taken to the dealer for service.

It is likely the vehicle has lost power steering

assistance.
If the steering icon is displayed and the “POWER

STEERING SYSTEM OVER TEMP” message is

displayed on the instrument cluster screen, this

indicates an over temperature condition in the

power steering system. Once driving conditions are

safe, pull over and let the vehicle idle for a few

moments until the icon and message turn off

Ú

page 115.

If the steering icon is displayed and the “SERVICE

POWER STEERING – ASSIST OFF” message is

displayed on the instrument cluster screen, this

indicates the vehicle needs to be taken to the

dealer for service

Ú

page 115.

NOTE:



Even if the power steering assistance is no

longer operational, it is still possible to steer the

vehicle. Under these conditions there will be a

substantial increase in steering effort, espe

-

cially at low speeds and during parking maneu

-

vers.



If the condition persists, see an authorized

dealer for service.

FUEL SAVER TECHNOLOGY 5.7L ENGINES

ONLY — IF EQUIPPED

This feature offers improved fuel economy by

shutting off four of the engine's eight cylinders

during light load and cruise conditions. The system

is automatic with no driver inputs or additional

driving skills required.

NOTE:

This system may take some time to return to full

functionality after a battery disconnect.

WARNING!

When servicing vehicles equipped with a

limited-slip or locking differential, never run the

engine with one rear wheel off the ground as the

vehicle may drive through the rear wheel

remaining on the ground and result in

unintended movement.

STARTING AND OPERATING

175

STOP/START SYSTEM — IF EQUIPPED

The Stop/Start function, included with eTorque

equipped vehicles, is developed to save fuel and

reduce emissions. The system will stop the engine

automatically as the vehicle decelerates at low

speeds if the required conditions are met.

Releasing the brake pedal or shifting out of DRIVE

will automatically restart the engine.
Vehicles equipped with eTorque contain a

heavy-duty motor generator and an additional

hybrid electric battery to store energy from vehicle

deceleration used to expand engine off energy

storage and for engine startup after a stop, as well

as providing engine torque assist when conditions

are met to enable this.

A

UTOSTOP

M

ODE

The Stop/Start feature is enabled after every

normal customer engine start. It will remain in

STOP/START NOT READY until you drive forward

with a vehicle speed greater than 2 mph (3 km/h).

At that time, the system will go into STOP/START

READY and if all other conditions are met, the

system may go into STOP/START AUTOSTOP

ACTIVE Autostop mode.

To Activate The Autostop Mode, The Following

Must Occur:
1. The system must be in STOP/START READY

state. A STOP/START READY message will be

displayed in the instrument cluster within the

Stop/Start section

Ú

page 115.

2. The vehicle must be decelerating and likely

coming to a complete stop.

3. The transmission gear selector must be in

DRIVE and the brake pedal pressed.

The engine will shut down, the tachometer will

move to the zero position and the stop/start

telltale will illuminate indicating you are in an

Autostop. While in an Autostop, the Climate

(ACC)

Adaptive Cruise Control (ACC) increases the driving

convenience provided by Cruise Control while

traveling on highways and major roadways.

However, it is not a safety system and not designed

to prevent collisions. The Cruise Control function

performs differently

Ú

page 177.

ACC will allow you to keep Cruise Control engaged

in light to moderate traffic conditions without the

constant need to reset your speed. ACC utilizes a

radar sensor and a forward facing camera

designed to detect a vehicle directly ahead of you

to maintain a set speed.

NOTE:



If the ACC sensor detects a vehicle ahead, ACC

will apply limited braking or acceleration (not to

exceed the original set speed) automatically to

maintain a preset following distance, while

matching the speed of the vehicle ahead.



Any chassis/suspension or tire size modifica

sion Warning system.



Fixed Speed Cruise Control (ACC not enabled)

will not detect vehicles directly ahead of you.

Always be aware of the feature selected

Ú

page 485.

WARNING!



Adaptive Cruise Control (ACC) is a conve

-

nience system. It is not a substitute for active

driver involvement. It is always the driver’s

responsibility to be attentive of road, traffic,

and weather conditions, vehicle speed,

distance to the vehicle ahead; and, most

importantly, brake operation to ensure safe

operation of the vehicle under all road condi

To Resume

If there is a set speed in memory, push the RES

(resume) button and then remove your foot from

the accelerator pedal. The instrument cluster

display will show the last set speed.
Resume can be used at any speed above 20 mph

(32 km/h) when only Fixed Speed Cruise Control is

being used.
Resume can be used at any speed above 0 mph

(0 km/h) when ACC is active.

NOTE:



If your vehicle is at a standstill for longer than

two seconds, then the driver will either have to

push the RES (resume) button, or apply the

accelerator pedal to reengage the Adaptive

Cruise Control (ACC) to the existing set speed.



ACC cannot be resumed if there is a stationary

vehicle in front of your vehicle in close proximity.

To Vary The Speed Setting

To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set

speed by pushing the SET (+) button, or decrease

speed by pushing the SET (-) button.

WARNING!

The Resume function should only be used if

traffic and road conditions permit. Resuming a

set speed that is too high or too low for

prevailing traffic and road conditions could

cause the vehicle to accelerate or decelerate too

sharply for safe operation. Failure to follow these

warnings can result in a collision and death or

serious personal injury.

STARTING AND OPERATING

183

U.S. Speed (mph)



Pushing the SET (+), or SET (-) button once will

result in a 1 mph speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 mph.



If the button is continually pushed, the set

speed will continue to adjust in 5 mph incre

-

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

Metric Speed (km/h)



Pushing the SET (+), or SET (-) button once will

result in a 1 km/h speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 km/h.



If the button is continually pushed, the set

speed will continue to adjust in 10 km/h incre

-

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

NOTE:

When you override and push the SET (+) button or

SET (-) buttons, the new set speed will be the

current speed of the vehicle.

When ACC Is Active



When you use the SET (-) button to decelerate, if

the engine’s braking power does not slow the

vehicle sufficiently to reach the set speed, the

brake system will automatically slow the

vehicle.



The ACC system decelerates the vehicle to a full

stop when following the vehicle in front. If your

vehicle follows the vehicle in front to a standstill,

after two seconds the driver will either have to

push the RES (resume) button, or apply the

accelerator pedal to reengage the ACC to the

existing set speed.



The ACC system maintains set speed when

driving uphill and downhill. However, a slight

speed change on moderate hills is normal. In

addition, downshifting may occur while climbing

uphill or descending downhill. This is normal

operation and necessary to maintain set speed.

When driving uphill and downhill, the ACC

system will cancel if the braking temperature

exceeds normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for Adaptive

Cruise Control (ACC) can be set by varying the

distance setting between four bars (longest), three

bars (long), two bars (medium) and one bar (short).

Using this distance setting and the vehicle speed,

ACC calculates and sets the distance to the vehicle

ahead. This distance setting displays in the

instrument cluster display.

Distance Settings

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

4

184

STARTING AND OPERATING

To increase the distance setting, push the

Distance Increase button and release. Each time

the button is pushed, the distance setting

increases by one bar (longer).
To decrease the distance setting, push the

Distance Decrease button and release. Each time

the button is pushed, the distance setting

decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will

maintain the set speed. If a slower moving vehicle

is detected in the same lane, the instrument

cluster displays the ACC Set With Target Detected

Indicator Light, and the system adjusts vehicle

speed automatically to maintain the distance

setting, regardless of the set speed.
The vehicle will then maintain the set distance

until:



The vehicle ahead accelerates to a speed above

the set speed.



The vehicle ahead moves out of your lane or

view of the sensor.



The distance setting is changed.



The system disengages.

The maximum braking applied by ACC is limited;

however, the driver can always apply the brakes

manually, if necessary.

NOTE:

The brake lights will illuminate whenever the ACC

system applies the brakes.
A Proximity Warning will alert the driver if ACC

predicts that its maximum braking level is not

sufficient to maintain the set distance. If this

occurs, a visual alert “BRAKE!” will flash in the

instrument cluster display and a chime will sound

while ACC continues to apply its maximum braking

capacity.

NOTE:

The “BRAKE!” screen in the instrument cluster

display is a warning for the driver to take action

and does not mean that the Forward Collision

Warning system is applying the brakes autono

-

mously.

Overtake Aid

When driving with Adaptive Cruise Control (ACC)

engaged, and following a vehicle, the system will

provide an additional acceleration up to the ACC

set speed to assist in passing the vehicle. This

additional acceleration is triggered when the driver

utilizes the left turn signal and will only be active

when passing on the left hand side.

ACC Operation At Stop

In the event that the ACC system brings your

vehicle to a standstill while following the vehicle in

front, if the vehicle in front starts moving within two

seconds of your vehicle coming to a standstill, your

vehicle will resume motion without the need for

any driver action.
If the vehicle in front does not start moving within

two seconds of your vehicle coming to a standstill,

the driver will either have to push the RES (resume)

button, or apply the accelerator pedal to reengage

the ACC to the existing set speed.

NOTE:

After the ACC system holds your vehicle at a stand

-

still for approximately three consecutive minutes,

the parking brake will be activated, and the ACC

system will be canceled.
While ACC is holding your vehicle at a standstill, if

the driver seat belt is unbuckled or the driver door

is opened, the parking brake will be activated, and

the ACC system will be canceled.

WARNING!

When the ACC system is resumed, the driver

must ensure that there are no pedestrians,

vehicles or objects in the path of the vehicle.

Failure to follow these warnings can result in a

collision and death or serious personal injury.

Display Warnings And Maintenance

“WIPE FRONT RADAR SENSOR IN FRONT OF

VEHICLE” WARNING

The “ACC/FCW Unavailable Wipe Front Radar

Sensor” warning will display and a chime will

sound when conditions temporarily limit system

performance.
This most often occurs at times of poor visibility,

such as in snow or heavy rain. The ACC system may

also become temporarily blinded due to

obstructions, such as mud, dirt or ice. In these

cases, the instrument cluster display will display

“ACC/FCW Unavailable Wipe Front Radar Sensor”

and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar

Sensor” message can sometimes be displayed

while driving in highly reflective areas (i.e. ice and

snow, or tunnels with reflective tiles). The ACC

system will recover after the vehicle has left these

areas. Under rare conditions, when the radar is not

tracking any vehicles or objects in its path this

warning may temporarily occur.

NOTE:

If the “ACC/FCW Unavailable Wipe Front Radar

Sensor” warning is active, Fixed Speed Cruise

Control is still available.

If weather conditions are not a factor, the driver

should examine the sensor. It may require cleaning

or removal of an obstruction. The sensor is located

in the camera in the center of the windshield, on

the forward side of the rearview mirror.
To keep the ACC system operating properly, it is

important to note the following maintenance

items:



Always keep the sensor clean. Carefully clear

the windshield.



Do not remove any screws from the sensor.

Doing so could cause an ACC system malfunc

-

tion or failure and require a sensor realignment.



Do not attach or install any accessories near the

sensor, including transparent material. Doing so

could cause an ACC system failure or malfunc

-

tion.

When the condition that deactivated the system is

no longer present, the system will return to the

“Adaptive Cruise Control Off” state and will resume

function by simply reactivating it.

NOTE:



If the “ACC/FCW Unavailable Wipe Front Radar

Sensor” message occurs frequently (e.g. more

than once on every trip) without any snow, rain,

mud, or other obstruction, have the radar

sensor realigned at an authorized dealer.



Installing a snowplow, front-end protector, an

aftermarket grille or modifying the grille is not

recommended. Doing so may block the sensor

and inhibit ACC/FCW operation.

“CLEAN FRONT WINDSHIELD” WARNING

The “ACC/FCW Limited Functionality Clean Front

Windshield” warning will display and a chime will

sound when conditions temporarily limit system

performance. This most often occurs at times of

poor visibility, such as in snow or heavy rain and

fog. The ACC system may also become temporarily

blinded due to obstructions, such as mud, dirt, or

ice on windshield, driving directly into the sun and

fog on the inside of glass. In these cases, the

instrument cluster display will show “ACC/FCW

Limited Functionality Clean Front Windshield” and

the system will have degraded performance.
This message can sometimes be displayed while

driving in adverse weather conditions. The ACC/

FCW system will recover after the vehicle has left

these areas. Under rare conditions, when the

camera is not tracking any vehicles or objects in its

path this warning may temporarily occur.
If weather conditions are not a factor, the driver

should examine the windshield and the camera

located on the back side of the inside rear view

mirror. They may require cleaning or removal of an

obstruction.

4

186

STARTING AND OPERATING

When the condition that created limited

functionality is no longer present, the system will

return to full functionality.

NOTE:

If the “ACC/FCW Limited Functionality Clean Front

Windshield” message occurs frequently (e.g. more

than once on every trip) without any snow, rain,

mud, or other obstruction, have the windshield and

forward facing camera inspected at an authorized

dealer.

SERVICE ACC/FCW WARNING

If the system turns off, and the instrument cluster

displays “ACC/FCW Unavailable Service Required”

or “Cruise/FCW Unavailable Service Required”,

there may be an internal system fault or a

temporary malfunction that limits ACC

functionality. Although the vehicle is still drivable

under normal conditions, ACC will be temporarily

unavailable. If this occurs, try activating ACC again

later, following an ignition cycle. If the problem

persists, see an authorized dealer.

Precautions While Driving With ACC

NOTE:



Aftermarket add-ons such as snowplows, lift

kits, and brush/grille bars can hinder module

performance. Ensure the radar/camera has no

obstructions in the field of view.



Height modifications can limit module perfor

-

mance and functionality.



Do not put stickers or easy passes over the

camera/radar field of view.



Any modifications to the vehicle that may

obstruct the field of view of the radar/camera

are not recommended.

In certain driving situations, ACC may have

detection issues. In these cases, ACC may brake

late or unexpectedly. The driver needs to stay alert

and may need to intervene. The following are

examples of these types of situations:

TOWING A TRAILER

ACC while towing a trailer is recommended only

with an Integrated Trailer Brake Controller.

Aftermarket trailer brake controllers will not

activate the trailer brakes when ACC is braking.

OFFSET DRIVING

ACC may not detect a vehicle in the same lane that

is offset from your direct line of travel, or a vehicle

merging in from a side lane. There may not be

sufficient distance to the vehicle ahead. The offset

vehicle may move in and out of the line of travel,

which can cause your vehicle to brake or

accelerate unexpectedly.
