NOTE:
If equipped with a touch screen radio all enabling/disabling
of air suspension features must be done through the radio.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
Air Suspension Modes
The Air Suspension system has multiple modes to protect the
system in unique situations:
AERO Mode
To improve aerodynamics, the air suspension system has a
feature which will put the vehicle into AERO height auto-
matically. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information. NOTE:
This mode is intended to be enabled with engine running.
Tire Jack Mode
To assist with changing a tire, the air suspension system has
a feature which allows the automatic leveling to be disabled.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” or “Uconnect Settings” in “Multi
-
media” if equipped with a touch screen radio for further
information.
NOTE:
This mode is intended to be enabled with engine running.
Transport Mode
For towing your vehicle with four wheels off the road, the air
suspension system has a feature which will put the vehicle
into Entry/Exit height and disable the automatic load
leveling system. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” or “Uconnect
Settings” in “Multimedia” if equipped with a touch screen
radio for further information.
NOTE:
This mode is intended to be enabled with engine running.

330 STARTING AND OPERATING
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 posi-
tion, 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 posi -
tion, 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 posi -
tion 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.
• Off-Road 1 (OR1) – Indicator lamps 4, 3, 2, and 1 will be
illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH) – Indicator lamps 4, 3, and 2 will be illuminated when the vehicle is in this position.
• Aero Mode – Indicator lamps 4 and 3 will be illuminated when the vehicle is in this position.
• Entry/Exit Mode – Indicator lamp 4 will be illuminated when the vehicle is in Entry Exit Mode. Entry/Exit mode
can be requested up to 33 mph (53 km/h). If vehicle speed
is reduced to, and kept below, 15 mph (24 km/h) indicator
lamp 3 will flash and indicator lamp 4 will remain solid
until Entry/Exit Mode is achieved at which point indicator
lamp 3 will turn off.
• Transport Mode – No indicator lamps will be illuminated. Transport Mode is disabled by driving the vehicle.
• Tire/Jack Mode – Indicator lamps 4 and 1 will be illumi -
nated. Tire/Jack Mode is disabled by driving the vehicle.

STARTING AND OPERATING 331
AXLE LOCKER SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically locking rear
differential. This differential, when engaged, mechanically
lock together 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 LOCKER
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.
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 situ -
ations or navigating terrain, which could possibly
cause the vehicle to become stuck.

will also continuously perform the dynamic vehicle cali-
bration to account for differences such as over or under
inflated tires and new tires.
• The driver must control the vehicle’s brakes themselves. Automatic emergency braking feature is NOT intended to
substitute for the driver during REVERSE maneuvers.
Enabling And Disabling The ParkSense Active Park

ParkSense Active Park Assist switch again (LED turns off). The ParkSense Active Park Assist system will turn off auto
-
matically for any of the following conditions:
• The parking maneuver is completed.
• Vehicle speed greater than 18 mph (30 km/h) when searching for a parking space.
• Vehicle speed greater than 5 mph (7 km/h) during active steering guidance into the parking space.
• Touching the steering wheel during active steering guid -

display timer for the image is initiated. The image will
continue to be displayed until the display timer exceeds 10
seconds.
NOTE:
• If the vehicle speed remains below 8 mph (13 km/h), the Rear View Camera image will be displayed continuously
until deactivated via the touchscreen button "X", the trans -
mission is shifted into PARK, or the ignition is placed in
the OFF position.
• The touchscreen button "X" to disable display of the camera image is made available ONLY when the vehicle is
not in REVERSE.
When enabled, active guide lines are overlaid on the image
to illustrate the width of the vehicle and its projected backup
path based on the steering wheel position. The active guide
lines will show separate zones that will help indicate the
distance to the rear of the vehicle.
