Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate
the current and desired transfer case selection. When you
select a different transfer case position, the indicator lights
will do the following:
If All Of The Following 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 Of The Following Shift Conditions Are
Not Met:
1. The indicator light for the current position will remain ON.
2. The newly selected position indicator light will continue 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, push the
current position, wait five seconds, and retry selection. To
find the shift requirements, 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 functioning 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.
316 STARTING AND OPERATING

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 or
4WD HIGH 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.Shifting Procedure
NOTE:
• If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The position indicator light for the previous posi-
tion will remain ON and the newly selected position
indicator light will continue to flash until all the require-
ments for the selected position have been met.
• If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.

STARTING AND OPERATING 317

When additional traction is required, the transfer case 4WD
HIGH and 4WD LOW positions can be used to maximize
torque to the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is accomplished
pushing the desired position on the 4WD Control Switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.
The 4WD HIGH and 4WD LOW positions are designed for
loose, slippery road surfaces only. Driving in the 4WD
HIGH and 4WD LOW positions on dry hard surfaced
roads may cause increased tire wear and damage to the
driveline components.
NOTE:The transfer case NEUTRAL button is located in
the center of the 4WD Control Switch and is pushed by
using a ballpoint pen or similar object. The transfer case
NEUTRAL position is to be used for recreational towing
only. Refer to “Recreational Towing” in “Starting And
Operating” for further information.

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, push the height selector
switch up 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 instrument cluster
message will be displayed when this occurs. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your key
fob for easier entry/loading. Refer to “Keys” in “Getting To
Know Your Vehicle” for further information.
CAUTION!
When in ENTRY/EXIT setting, be aware of your sur-
roundings, you may not have the clearance required 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 oncom-
ing 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 “Instrument Cluster Display” in “Getting To
Know 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 Settings” in “Multimedia” for
further information.

330 STARTING AND OPERATING

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.
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 reengage at 20 mph
(32 km/h).
NOTE:Left to right wheel speed difference may be neces-
sary 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 simi-
larly 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
6
STARTING AND OPERATING 335

rear wheel on an excessively slippery surface, slight mo-
mentary application of the parking brake may be necessary
to gain maximum traction.
WARNING!
When servicing vehicles equipped with a limited-slip
or locking differential never run the engine with one
rear wheel off the ground since the vehicle may drive
through the rear wheel remaining on the ground and
result in unintended movement.
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 give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
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 STEER-
ING SYSTEM OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that extreme steer-
ing maneuvers may have occurred which caused 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.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed the in-
strument cluster screen, they indicate the vehicle needs to
be taken to the dealer for service. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.
