OPERATION

Air Suspension Switch

The indicator lamps 1 through 4 will illuminate to show the
current position of the vehicle. Flashing indicator lamps
will show a position which the system is working to
achieve. When raising or lowering, the flashing indicator
lamp is the position the system is working to achieve.
Pushing the height selector switch up once will move the
suspension one position higher from the current position,
assuming all conditions are met (i.e., key in ON/RUN
position, engine running, speed below threshold, etc.).
The height selector switch can be pushed up multiple
times, each push will raise the requested level by one
position up to a maximum position of OR or the highest
position allowed based on current conditions
(i.e., vehicle speed, etc.). Pushing the height selector switch down once will move
the suspension one position lower from the current level,
assuming all conditions are met (i.e., key in ON/RUN
position, engine running, doors closed, speed below
threshold, etc.). The height selector switch can be pushed
down multiple times, each push will lower the requested
level by one position down to a minimum of Entry/Exit
Mode or the lowest position allowed based on current
conditions (i.e., vehicle speed, etc.).
Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and instrument cluster display messages will operate the
same for automatic changes and user requested changes.

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.
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.
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 navigating terrain, which
could possibly cause the vehicle to become stuck.

23_DT_OM_EN_USC_t.book Page 140

STARTING AND OPERATING141
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
ELECTRIC POWER STEERING
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 an authorized 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
Úpage 98.
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 an authorized dealer for service
Úpage 98.
NOTE:
 Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 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 function -
ality after a battery disconnect.
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.
AUTOSTOP MODE
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.
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.

CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise Control
system, or the Adaptive Cruise Control (ACC) system:
 Cruise Control will keep your vehicle at a constant
preset speed.
 Adaptive Cruise Control (ACC) will adjust the vehicle
speed up to the preset speed to maintain a distance
with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not enabled,
Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected.
 Only one Cruise Control feature can operate at a time.
For example, if Fixed Speed Cruise Control is enabled,
Adaptive Cruise Control will be unavailable, and vice
versa.

STARTING AND OPERATING157
When you move the gear selector to the REVERSE posi -
tion and Front or Rear ParkSense is turned off, the
instrument cluster display will show a vehicle graphic
with "OFF" in the corresponding side. This vehicle
graphic will be displayed for as long as the vehicle is in
REVERSE.
 ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
 Use the ParkSense switch to turn the ParkSense
system off if obstacles such as bicycle carriers, trailer
hitches, etc. are placed near the rear fascia/bumper.
Failure to do so can result in the system misinter -
preting a close obstacle as a sensor problem, causing
the “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message to be appear in the instrument cluster
display.
 ParkSense should be disabled when the tailgate is in
the lowered or open position. A lowered tailgate could
provide a false indication that an obstacle is behind the
vehicle and could also cause a false braking event. 
The Rear ParkSense system will automatically disable
when the system detects that a trailer with trailer
brakes has been connected to the Integrated Trailer
Brake Module.
 The Front ParkSense system will automatically disable
if a snowplow has been connected to the vehicle.
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space,
providing audible/visual instructions through the
instrument cluster display, and controlling the steering
wheel. The ParkSense Active Park Assist system is defined
as “semi-automatic” since the driver maintains control of
the accelerator, gear selector and brakes. Depending on
the driver's parking maneuver selection, the ParkSense
Active Park Assist system is capable of maneuvering a
vehicle into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
WARNING!
Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon -
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
 Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly be
disconnected from the vehicle when the vehicle is
not used for towing. Failure to do so can result in
injury or damage to vehicles or obstacles because
the hitch ball will be much closer to the obstacle than
the rear fascia/bumper when the vehicle sounds the
continuous tone. Also, the sensors could detect the
ball mount and hitch ball assembly, depending on its
size and shape, and give a false indication that an
obstacle is behind the vehicle, and could cause false
braking.
CAUTION!
ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
 The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using Park -
Sense.

158STARTING AND OPERATING
NOTE:
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
 The system is provided to assist the driver and not to
substitute the driver.
 During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to
remove their hands from the steering wheel, the
system will cancel, and the driver will be required to
manually complete the parking maneuver.
 The system may not work in all conditions
(e.g. environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space that has
surfaces that will absorb the ultrasonic sensor waves).
 New vehicles from the dealership must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature.
 The driver must control the vehicle’s brakes. The auto -
matic emergency braking feature is NOT intended to
substitute for the driver during REVERSE maneuvers.ENABLING AND DISABLING THE

 When searching for a parking space, use the turn
signal indicator to select which side of the vehicle you
want to perform the parking maneuver. The ParkSense
Active Park Assist system will automatically search for
a parking space on the passenger's side of the vehicle
if the turn signal is not activated.
 The driver needs to make sure that the selected
parking space for the maneuver remains free and clear
of any obstructions (e.g. pedestrians, bicycles, etc.).
 The driver is responsible to ensure that the selected
parking space is suitable for the maneuver and
free/clear of anything that may be overhanging or
protruding into the parking space (e.g., ladders, tail-
gates, etc. from surrounding objects/vehicles).
 When searching for a parking space, the driver should
drive as parallel or perpendicular (depending on the
type of maneuver) to other vehicles as possible. 
The feature will only indicate the last detected parking
space (example: if passing multiple available parking
spaces, the system will only indicate the last detected
parking space for the maneuver). A parking space is
considered invalid after the vehicle is 32 ft (10 m) or
more away from it.
When an available parking space has been found, and the
vehicle is not in position, you will be instructed to move
forward to position the vehicle for a perpendicular or
parallel parking sequence (depending on the type of
maneuver being performed).

Space Found — Keep Moving Forward

Once the vehicle is in position, you will be instructed to
stop the vehicle’s movement and remove your hands from
the steering wheel. When the vehicle comes to a standstill
(your hands still removed from the steering wheel), you will
be instructed to place the gear selector into the REVERSE
position.
