cluster and indicate the current and desired transfer case
selection. When you select a different transfer case posi-
tion, the indicator lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain ON.
2. The newly selected position indicator light will con- tinue to flash.
3. The transfer case will notshift. NOTE:
Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may

allow the vehicle to roll which may cause personal
injury or death.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD, 4WD
AUTO or 4WD LOCK positions at a given road speed.
Take care not to overspeed the engine and do not exceed
25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
drivetrain. Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

For additional information on the appropriate use of each
transfer case mode position, see the information below:
2WD
Rear-Wheel Drive High Range - This range is for normal
street and highway driving on dry hard surfaced roads.
4WD AUTO
Four-Wheel Drive Auto Range - This range sends power
to the rear wheels. The four–wheel drive system will be
automatically engaged when the vehicle senses a loss of
traction. Additional traction for varying road conditions.

STARTING AND OPERATING 407

When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.
2WD To 4WD AUTO Or 4WD LOCK
Press the desired position on the 4WD Control Switch to
shift the transfer case. Shifts between 2WD and 4WD
AUTO and 4WD LOCK can be done with the vehicle
stopped or in motion. With the vehicle in motion, the
transfer case will engage/disengage faster if you momen-
tarily release the accelerator pedal after turning the
control switch. If the vehicle is stopped, the ignition
switch must be in the ON position with the engine either
running or OFF. This shift cannot be completed if the
ignition switch is in the ACC position. 2WD Or 4WD AUTO Or 4WD LOCK To 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some
gear noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. Use either of
the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, press the desired position on the transfer case control switch.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
5
STARTING AND OPERATING 409

Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition switch in the ON position and theengine running, shift the transmission into NEUTRAL.
3. Press the desired position on the transfer case control switch.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
NOTE:
• If Steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift
attempt is in process, the desired position indicator
light will flash continuously while the original position
indicator light is ON, until all requirements have been
met. •
The ignition switch must be in the ON position for a
shift to take place and for the position indicator lights
to be operable. If the ignition switch is not in the ON
position, then the shift will not take place and no
position indicator lights will be on or flashing.
AIR SUSPENSION SYSTEM — IF EQUIPPED
Description
The air suspension system provides full time load level-
ing capability along with the benefit of being able to
adjust vehicle height by the push of a button.
410 STARTING AND OPERATING

NOTE:Aero Mode may be disabled through vehicle
settings in the Electronic Vehicle Information Center
(EVIC) or in the Uconnect™ Access 8.4 Radio (If
Equipped). Refer to “Electronic Vehicle Information Cen-
ter (EVIC)” in “Understanding Your Instrument Panel”
or “Uconnect™ Access Settings” in “Understanding Your
Instrument Panel” for further information.
• Entry/Exit Mode (Lowers the vehicle approximately 2
in (51 mm) – This position lowers the vehicle for easier
passenger entry and exit as well as lowering the rear of
the vehicle for easier loading and unloading of cargo.
To enter Entry/Exit Mode, press the “Down” button
once from the NRH while the vehicle speed is below
33 mph (53 km/h). Once the vehicle speed goes below
15 mph (24 km/h) the vehicle height will begin to
lower. If the vehicle speed remains between 15 mph
(24 km/h) and 25 mph (40 km/h) for greater than
60 seconds, or the vehicle speed exceeds 25 mph
(40 km/h) the Entry/Exit change will be cancelled. To return to Normal Height Mode, press the “Up” button
once while in Entry/Exit or drive the vehicle over
15 mph (24 km/h). Entry/Exit mode may not be
available due to vehicle payload, an EVIC message
will be displayed when this occurs. Refer to
Electronic
Vehicle Information Center (EVIC) inUnderstanding
Your Instrument Panel for further information.
NOTE: Entry/Exit mode may be achieved using your
key fob for easier entry/loading. Refer to “A Word About
Your Keys” in “Things To Know Before Starting Your
Vehicle” for further information.
• When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance re-
quired for certain areas and vehicle damage may
occur.
The system requires that the ignition be in 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 on-
coming 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. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.NOTE:
If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect™ Access
Settings” in “Understanding Your Instrument Panel” for
further information.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal injury or damage to the system, see your
authorized dealer for service.
Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
