4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster will
flash and go out when the shift is complete.
NOTE:
•If shift conditions/interlocks are not met,
or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 MPH or 5 KPH Put Trans in
N Press 4 Low” message will flash from
the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding
Your Instrument Panel” for further infor-
mation. •Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped; how-
ever, difficulty may occur due to the mating
clutch teeth not being properly aligned.
Several attempts may be required for clutch
teeth alignment and shift completion to
occur. The preferred method is with the
vehicle rolling 0 to 3 mph (0 to 5 km/h). If the
vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not allow the
shift.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position,
engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a
pen, etc.) for four seconds until the LED light by
the switch starts to blink indicating shift in
progress. The light will stop blinking (stay on
solid) when the NEUTRAL shift is complete.
5. Repeat Steps 1 to 4 to shift out of NEU-
TRAL.
NOTE:
If shift conditions/interlocks are not met, a
“To Tow Vehicle Safely, Read Neutral Shift
Procedure in Owners Manual” message will
flash from the Electronic Vehicle Informa-
tion Center (EVIC). Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further
information.Neutral Switch

The system requires that the engine be running
for all changes. When lowering the vehicle all of
the doors, including the liftgate, 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.
The Quadra-Lift™ air suspension 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 ap-
pearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Press and hold both the “Up” and
“Down” buttons simultaneously between 5 and
10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediatelyafter both buttons have been released. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.
WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.
Electronic Vehicle Information
Center (EVIC) Display Messages
When the appropriate conditions exist, a mes-
sage will appear in the EVIC display. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing indicator lamps will show a position which
the system is working to achieve. When raising,
if multiple indicator lamps are flashing on the
“Up” button, the highest flashing indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pressing the “UP” button once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.
engine running, speed below threshold, etc).
The “UP” button can be pressed multiple times,
each press will raise the requested level by one
position up to a maximum position of OR2 or the
highest position allowed based on current con-
ditions (i.e. vehicle speed, etc).

If you stall or begin to lose forward motion
while climbing a steep hill, allow your vehicle to
come to a stop and immediately apply the
brakes. Restart the engine, and shift into RE-
VERSE. Back slowly down the hill, allowing the
compression braking of the engine to help regu-
late your speed. If the brakes are required to
control vehicle speed, apply them lightly and
avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion,
or cannot make it to the top of a steep hill or
grade, never attempt to turn around. To do so
may result in tipping and rolling the vehicle.
Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in
NEUTRAL using only the brake.Remember, never drive diagonally across a
hill always drive straight up or down.
If the wheels start to slip as you approach the
crest of a hill, ease off the accelerator and
maintain forward motion by turning the front
wheels slowly. This may provide a fresh “bite”
into the surface and will usually provide traction
to complete the climb.Traction DownhillShift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the
vehicle go slowly down the hill with all four
wheels turning against engine compression
drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
•
Completely inspect the underbody of your ve-
hicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
•
Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness, par-
ticularly on the chassis, drivetrain compo-
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
• Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
247
•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a colli-
sion. If you have been operating your vehicle
in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driv-
ing in mud, slush or similar conditions, check
the wheels for impacted material. Impacted
material can cause a wheel imbalance and
freeing the wheels of it will correct the
situation.
FUEL SAVER TECHNOLOGY
5.7L ENGINE 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.
POWER STEERING
3.6L And 5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost. If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and dur-
ing parking maneuvers.
NOTE:
•
Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system.
This noise should be considered normal,
and it does not in any way damage the
steering system.
248
WARNING!
Continued operation with reduced power
steering assist could pose a safety risk to
yourself and others. Service should be ob-
tained as soon as possible.
CAUTION!
Prolonged operation of the steering system
at the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage
to the power steering pump may occur.
3.0L Diesel EngineYour vehicle is equipped with an electro-
hydraulic power steering system that 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 theelectro-hydraulic power steering system experi-
ences a fault that prevents it from providing
power steering assist, then the system will
provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop
power steering assistance in order to prevent
damage to the system. Normal operation will
resume once the system is allowed to cool.
If the “SERVICE POWER STEER-
ING SYSTEM” message and a
flashing icon are displayed on the
EVIC screen, it indicates that the
vehicle needs to be taken to the
dealer for service. It is likely the
vehicle has lost power steering assistance. Re-
fer to “Electronic Vehicle Information (EVIC)” in
“Understanding Your Instrument Panel” for fur-
ther information. If the “POWER STEERING SYSTEM OVER
TEMP” message and an icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the
power steering system. You will lose power
steering assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Informa-
tion (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•
Even if 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 steer-
ing effort, especially at very low vehicle
speeds and during parking maneuvers.
•
If the condition persists, see your autho-
rized dealer for service.
249
Power Steering Fluid CheckChecking the power steering fluid level at a
defined service interval is not required. The fluid
should only be checked if a leak is suspected,
abnormal noises are apparent, and/or the sys-
tem is not functioning as anticipated. Coordi-
nate inspection efforts through an authorized
dealer.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can dam-
age your power steering components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
Fluid level should be checked on a level sur-
face and with the engine off to prevent injury
from moving parts and to ensure accurate fluid
level reading. Do not overfill. Use only manu-
facturer’s recommended power steering fluid.
If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the shift
lever in the PARK position.
The foot operated parking brake is located
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
park brake pedal fully. To release the parking
brake, press the park brake pedal a second
time and let your foot up as you feel the brake
disengage.When the parking brake is applied with the
ignition switch in the ON position, the “Brake
Warning Light” in the instrument cluster will
illuminate.
NOTE:
•
When the parking brake is applied and the
transmission is placed in gear, the “Brake
Warning Light” will flash. If vehicle speed
is detected, a chime will sound to alert the
driver. Fully release the parking brake
before attempting to move the vehicle.
Parking Brake
250
•This light only shows that the parking
brake is applied. It does not show the
degree of brake application.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. Apply the parking brake before placing
the shift lever in PARK, otherwise the load on
the transmission locking mechanism may make
it difficult to move the shift lever out of PARK.
The parking brake should always be applied
whenever the driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when parked to
guard against vehicle movement and pos-
sible injury or damage.
(Continued)
WARNING!(Continued)
•When leaving the vehicle, always remove
the key fob from the ignition and lock your
vehicle. Never leave children alone in a
vehicle, or with access to an unlocked
vehicle. Allowing children to be in a vehicle
unattended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the shift lever.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to chil-
dren), and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-
Go™ in the ACC or ON/RUN position. A
child could operate power windows, other
controls, or move the vehicle.
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and a collision.
(Continued)
WARNING!(Continued)
•Always fully apply the parking brake when
leaving your vehicle, or it may roll and
cause damage or injury. Also be certain to
leave the transmission in PARK. Failure to
do so may allow the vehicle to roll and
cause damage or injury.
CAUTION!
If the “Brake Warning Light” remains on with
the parking brake released, a brake system
malfunction is indicated. Have the brake
system serviced by an authorized dealer
immediately.
251
The “ESC Activation/Malfunction Indicator Light”
located in the instrument cluster will start to flash
as soon as the tires lose traction and the ESC
system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the
TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during accelera-
tion, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) can-
not prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent collisions, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent col-
lisions resulting from loss of vehicle control
due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful
(Continued)
WARNING!(Continued)
driver can prevent collisions. The capabilities
of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.
The ESC system has two available operating
modes in 4WD HIGH range and two-wheel
drive vehicles, and one operating mode in 4WD
LOW range.
High Range (Four-Wheel Drive Models)
On
This is the normal operating mode for ESC in
4WD HIGH range. Whenever the vehicle is
started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL
back to 4WD HIGH range, the ESC system will
be in this “On” mode. This mode should be used
for most driving situations. ESC should only be
turned to “Partial Off” mode for specific reasons
as noted below. Partial Off
This mode is entered by momentarily pressing
the “ESC OFF” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
BLD feature described in the TCS section, has
been disabled and the “ESC Off Indicator Light”
will be illuminated. All other stability features of
ESC function normally. This mode is intended to
be used if the vehicle is in deep snow, sand, or
gravel conditions and more wheel spin than
ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily
press the “ESC OFF” switch. This will restore
the normal “ESC On” mode of operation.
When in “Partial Off” mode, the TCS functional-
ity of ESC, (except for the limited slip feature
described in the TCS section), has been dis-
abled and the “ESC Off Indicator Light” will be
illuminated. All other stability features of ESC
function normally. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
