QUADRA-TRAC I®
FOUR-WHEEL DRIVE
Quadra-Trac I®Operating
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
®
FOUR-WHEEL DRIVE
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.

will be illuminated when the vehicle is
in Park Mode.WARNING!
• You or others could be injured if you leave the vehicle unattended
with the transfer case in the N
(Neutral) position without first fully
engaging the parking brake. The
transfer case N (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.
• The air suspension system uses a high pressure volume of air to
operate the system. To avoid
personal injury or damage to the
system, see your authorized dealer
for service.
Hill Start Assist/Hill
Descent Control
• The Hill Start Assist system assists the
driver when starting a vehicle from a
stop on a hill.
• The Hill Descent Control system maintains vehicle speed while
descending hills during off-road
driving situations and is available in
