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 (8 km/h) Put Trans in
N Press 4 Low” message will flash from the Electronic Vehicle Information Center
(EVIC).

7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle
movement.
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) if the transfer case is in high range.
The level will change to Off-Road 1 if the transfer case is in Low range.
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
Off-Road 1.
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.

• Avoid using speed control when Paddle Shift mode is engaged.
• Transmission shifting will be more noticeable when Paddle Shift Mode is engaged.
• To disengage Paddle Shift Mode, hold the shift lever to the right or press and hold
the (+) shift paddle until “D” is once again displayed in the instrument cluster. You
can shift in or out of the Paddle Shift Mode at any time without taking your foot off
the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive
wheels could lose their grip and the vehicle could skid, causing a collision or
personal injury.
SELEC-TRACK™
Selec-Track™ 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-Track™ positions:
•Sport- Dry weather, on-road calibration. Performance based tuning that provides
a rear wheel drive feel but with improved handling and acceleration over a
two-wheel drive vehicle. The active suspension system will be in a semi firm mode,
and a green flag will light up in the instrument cluster.
•Snow- Tuning 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. This position balances traction with seamless steering feel to provide
improved handling and acceleration over two-wheel drive vehicles.
•Track- This position offers track road calibration for use on high traction surfaces.
Driveline is maximized for traction. Some binding may be felt on less forgiving
surfaces.
•To w- Use this mode for towing. Vehicle suspension will go to Firm mode and peak
power will be limited in the engine controls.

SUMMER/THREE-SEASON TIRES
• This vehicle may be equipped with wheels and tires to enhance traction in both
wet and dry conditions.
• Summer tires are not intended to be driven in snow or on ice.
• Summer tires have significantly reduced grip in temperatures below 50°F (10°C)
• Use summer tires only in sets of four.
NOTE:
Summer tires will not contain the all season designation or mountain/snowflake
symbol on the sidewall of the tire.
WARNING!
Do not use summer tires in snow/ice conditions. You could lose control, resulting
in severe injury or death. Driving too fast for conditions also creates the possibility
of loss of vehicle control.

• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
• To improve the vehicle's traction when starting off in deep snow, sand or gravel, it
may be desirable to switch the ESC system to Partial Off mode by momentarily
pressing the ESC Off
switch located below the climate controls, on the switch
panel.
- Electronic Stability Control (ESC) OFF Indicator Light
This light indicates the Electronic Stability Control (ESC) is off.
- Charging System Light
This light shows the status of the electrical charging system. If the charging system
light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However,
the conventional brake system will continue to operate normally if the BRAKE
warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
