Instructions/Precautions - 3.6L
Only
• The Quadra-Trac I®is a single-speed
(HI range only) transfer case, which
provides convenient full-time
four-wheel drive. No driver interaction
is required. The Brake Traction Control
(BTC) System, which combines
standard ABS and Traction Control,
provides resistance to any wheel that
is slipping to allow additional torque
transfer to wheels with traction.

Quadra-Trac II®/Quadra-Drive
II®Operating Instructions/
Precautions
• The Quadra-Trac II®/Quadra-Drive
II®transfer case is fully automatic in
the normal driving 4WD HI mode. The Quadra-Trac II
®/Quadra-Drive
II®transfer case provides three mode
positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
• This transfer case is fully automatic in the 4WD HI mode.
• When additional traction is required, the 4WD LOW position can be used
to lock the front and rear driveshafts
together and force the front and rear
wheels to rotate at the same speed.
The 4WD LOW position is intended
for loose, slippery surfaces only.
Driving in the 4WD LOW position on
dry, hard-surfaced roads may cause
increased tire wear and damage to
driveline components.
• When operating your vehicle in 4WD LOW, the engine speed is
approximately three times that of the
4WD HI position at a given road
speed. Take care not to overspeed the
engine and do not exceed 25 mph
(40 km/h).
NOTE:
• If shift conditions/interlocks are not met, or a transfer case motor temperature
protection condition exists, a “For 4x4
Low Slow Below 5 MPH or 8 KPH Put
Trans in N Press 4 Low” message will
flash from the Electronic Vehicle
Information Center (EVIC).
Shifting Procedures
4WD HI To 4WD LOW
• With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition
switch in the ON/RUN 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 begin to flash and remain on solid
when the shift is complete.
OFF-ROAD CAPABILITIES
56

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/RUN 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 turn off when the shift is
complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor
temperature protection exists, a “For 4x4
Low Slow Below 5 MPH or 8 KPH Put
Trans in N Press 4 Low” message will
flash on the Electronic Vehicle
Information Center (EVIC).
• Shifting into or out of 4WD LOW is possible with the vehicle completely
stopped; however, 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
• Turn the ignition switch to theON/RUN position, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL. • Press and hold the NEUTRAL button
located near the 4WD mode control
knob with a pen or similar object for
four seconds. The indicator light will
begin to flash indicating the shift is in
progress. The light will stop blinking
(stay on solid) when the NEUTRAL shift
is complete. A “4WD SYSTEM IN
NEUTRAL” message will display on
the Electronic Vehicle Information
Center (EVIC).
• Repeat these Steps to shift out of NEUTRAL.
SELEC-TERRAIN™
• Selec-Terrain™ combines thecapabilities of the vehicle control
systems, along with driver input, to
provide the best performance for all
terrains.
Rotate the mode control knob to select the
following Selec-Terrain™ positions: • Sport – Dry weather, on-road
calibration. Only available in 4WD
High range. Performance-based
tuning that provides a rear wheel
drive feel but with improved handling
and acceleration over a two-wheel
drive vehicle. The Electronic Stability
Control will set to allow more driver
control of the vehicle while
maintaining safe handling controls.
The vehicle will lower (if equipped
with Air Suspension) by 0.59 inches
(15 mm) in the SPORT mode.
• Snow – The Electronic Stability
Control is set for additional stability in
inclement weather. Use on and off
road on loose traction surfaces such
as snow.
• Auto – Fully automatic full-time
four-wheel drive operation can be
used on and off road. Balances
traction with steering feel to provide
improved handling and acceleration
over two-wheel drive vehicles.
OFF-ROAD CAPABILITIES
57

•Sand/Mud – Off-road calibration
for use on low traction surfaces such
as mud, sand, or wet grass. Driveline
is maximized for traction. Some
binding may be felt on less forgiving
surfaces. The electronic brake controls
are set to limit traction control
management of throttle and wheel
spin.
• Rock – Off-road calibration only
available in 4WD Low range. The
vehicle is raised (if equipped with Air
Suspension) for improved ground
clearance. Traction based tuning with
improved steer-ability for use on high
traction off-road surfaces. Activates
the Hill Descent Control for steep
downhill control. Use for low speed
obstacles such as large rocks, deep
ruts, etc.
Quadra-Lift™
• The Quadra-Lift™ air suspension system provides full time load leveling
capability along with the benefit of
being able to adjust vehicle height by
the push of a button. Quadra-Lift™ is
available with both Quadra-Trac II
®
and Quadra-Drive II™.
• 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. • The Quadra-Lift™ air suspension
system uses a lifting and lowering
pattern which keeps the headlights
from shining into oncoming 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, you may notice that the air suspension system
operates briefly. This is normal. The
system is correcting the position of the
vehicle.
• To assist with changing a spare tire, the Quadra-Lift™ air suspension
system has a feature 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
immediately after both buttons have
been released. Driving the vehicle
over 5 mph (8 km/h) will return the
air suspension to normal operation.
• An audible chime will be heard whenever a system error has been
detected.
Operation • Pressing the “Up” or “Down” button once will move the suspension one
position higher or lower from the
current position, assuming all
conditions are met (i.e., engine
running and all doors and liftgate
closed).
• The 4 indicator lamps will illuminate to show the current position of the
vehicle. Flashing indicator lamps will
show a position which the system is
working to achieve. If multiple
indicator lamps are flashing on the
“Up” button, the highest flashing
indicator lamp is the position the
system is working to achieve.

TOW/HAUL MODE
• When driving in hilly areas, towing atrailer, carrying a heavy load, etc.,
and frequent transmission shifting
occurs, press the TOW/HAUL switch
to select TOW/HAUL mode. This will
improve performance and reduce the
potential for transmission overheating
or failure due to excessive shifting.
When operating in TOW/HAUL
mode, transmission upshifts are
delayed, and the transmission will
automatically downshift (for engine
braking) during steady braking
maneuvers.
• The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to
indicate that TOW/HAUL mode has
been activated. Pressing the switch a
second time restores normal
operation. If the TOW/HAUL mode is
desired, the switch must be pressed
each time the engine is started.

• Start the engine and shift the transmission into REVERSE.
• Release the brake pedal for five seconds and ensure that there is no
vehicle movement.
• Turn the engine off and firmly apply the parking brake.
• Shift the transmission into PARK and remove the Key Fob.
• Attach the vehicle to the tow vehicle using a suitable tow bar and release
the parking brake.
NOTE: Vehicles equipped with
Quadra-Lift™ must be lowered to the
“Park” (lowest) level, and have automatic
leveling disabled, before tying them down
(from the body) on a trailer or a flatbed
truck. Refer to “Quadra-Lift™” in
“Off-Road Capabilities” for more
information. If the vehicle cannot be
lowered to the “Park” level (for example,
engine will not run), tie-downs must be
fastened to the axles (not the body). Failure
to follow these instructions may cause fault
codes to be set and/or loss of proper
tie-down tension.CAUTION!
• Towing with the rear wheels on the ground will cause severe
transmission damage. Damage
from improper towing is not
covered under the New Vehicle
Limited Warranty.
• Front or rear wheel lifts should not be used. Internal damage to the
transmission or transfer case will
occur if a front or rear wheel lift is
used when recreational towing.
• It is necessary to follow these steps to be certain that the transfer case
is fully in NEUTRAL before
recreational towing to prevent
damage to internal parts.
WARNING!
You or others could be injured 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 even if the transmission is in
PARK. The parking brake should
always be applied when the driver is
not in the vehicle.
UTILITY

• When the malfunction indicator is illuminated, the system may not be able to detect orsignal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may
result.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or theparking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an
Anti-Lock Brake System problem.
• We recommend you drive to the nearest service center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., mayilluminate the MIL after engine start. The vehicle should be serviced if the light stays on
through several typical driving cycles. In most situations, the vehicle will drive normally
and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We
recommend you do not operate the vehicle. Have the vehicle serviced immediately.

• Block both the front and rear of thewheel diagonally opposite of the jacking
position. For example, if changing the
right front tire, block the left rear wheel.
NOTE: Passengers should not remain in the
vehicle when the vehicle is being jacked.
Jacking And Tire Changing Instructions
• Remove the spare tire, jack and tools from their stored location.
• Loosen (but do not remove) the wheel lug nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
• Assemble the jack and jacking tools. Connect the jack handle driver to the extension, then to the lug wrench.
• Place the jack: • For front wheels, place the jack and protective cap right under the triangle on the body flange, just behind the front tire.
• For rear wheels, place the jack andprotective cap right under the triangle
on the rear tie-down bracket, just
forward of the rear tire.
WHAT TO DO IN EMERGENCIES

• Turn the jack screw clockwise to firmlyengage the jack saddle with the lift
area of the sill flange.
• Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire.
• Remove the lug nuts, wheel cover (if equipped) and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Do NOT attempt to install a center cap or wheel
cover on the compact spare. Lightly tighten the lug nuts clockwise. To avoid the risk of
forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been
lowered.
• Lower the vehicle by turning the jack screw counterclockwise, and remove the jack and wheel blocks.
• Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each one has been tightened twice. The correct wheel nut
tightness is 110 ft lbs (150 N•m). If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or at a service station.
• Secure the tire, jack, and tools in their proper locations.
NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down
may result in scratching or damage to the wheel face.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the
jack or changing the wheel.
• Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body
under a vehicle that is on a jack. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a
firm, level surface only. Avoid ice or slippery areas.
