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).
The Neutral position disengages the pow-
ertrain from the wheels, allowing the ve-
hicle to be flat towed behind another vehicle.

Repeat these Steps 1 through 5 to shift out of NEUTRAL.
SELEC-TERRAIN
Selec-Terrain combines the capabilities 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:
Snow – Tuning set for additional stability in inclement weather. Use on and off road
on loose traction surfaces such as snow. When in Snow mode (depending on certain
operating conditions), the transmission may use second gear (rather than first gear)
during launches, to minimize wheel slippage. If equipped with air suspension, the
level will change to Normal Ride Height (NRH).
Auto – Fully automatic full time four-wheel drive operation can be used on and off
road. Balances traction with seamless steering feel to provide improved handling and
acceleration over two-wheel drive vehicles. If equipped with air suspension, the level
will change to NRH.
Sand – Off road calibration for use on low traction surfaces such as 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. If equipped with air suspension, the level will change to
NRH.
OFF-ROAD CAPABILITIES (4WD OPERATION)

Mud– Off road calibration for use on low traction surfaces such as mud. 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. If equipped with air suspension, the level will change to Off-Road 1.
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. Activate the Hill
Descent Control for steep downhill control. Use for low speed obstacles such as large
rocks, deep ruts, etc. If equipped with air suspension, the vehicle level will change
to Off-Road 2. If the Selec-Terrain switch is in ROCK mode, and the transfer case is
switched from 4WD Low to 4WD High, the Selec-Terrain system will return to AUTO.
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 shin-
ing 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. The feature
controls are located in the radio screen. 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.
