grip and the vehicle could skid, causing a collision or
personal injury.
FOUR-WHEEL DRIVE OPERATION
Quadra-Trac I® Operating Instructions/
Precautions — If Equipped
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.
NOTE:
The Quadra-Trac I® system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Oper-
ating” for further information.
Quadra-Trac II® Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II® transfer case is fully automatic in
the normal driving 4WD AUTO mode. The Quadra-Trac
II® transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW

STARTING AND OPERATING 413

•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
• A flashing “N” position indicator light indicates that
shift requirements have not been met.
Quadra-Drive® II System — If Equipped
The optional Quadra-Drive® II System features two
torque transfer couplings. The couplings include an
Electronic Limited-Slip Differential (ELSD) rear axle and
the Quadra-Trac II® transfer case. The optional ELSD
axle is fully automatic and requires no driver input to
operate. Under normal driving conditions, the unit func-
tions as a standard axle, balancing torque evenly between left and right wheels. With a traction difference between
left and right wheels, the coupling will sense a speed
difference. As one wheel begins to spin faster than the
other, torque will automatically transfer from the wheel
that has less traction, to the wheel that has traction. While
the transfer case and axle coupling differ in design, their
operation is similar. Follow the Quadra-Trac II® transfer
case shifting information, preceding this section, for
shifting this system.SELEC-TERRAIN™ — IF EQUIPPED
Description
Selec-Terrain™ combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.
5
STARTING AND OPERATING 421

Selec-Terrain™ consists of the following 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 im-
proved 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 maxi-
mized 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.
Selec-Terrain™ Switch
422 STARTING AND OPERATING

•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 De-
scent 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.Electronic Vehicle Information Center (EVIC)
Display Messages
When the appropriate conditions exist, a message will
appear in the EVIC display. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
QUADRA-LIFT™ — IF EQUIPPED
Description
The Quadra-Lift™ air suspension system provides full
time load leveling capability along with the benefit of
vehicle height adjustment by the push of a button.

STARTING AND OPERATING 423

Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a
lower gear than necessary to maintain forward motion.
Over-revving the engine can spin the wheels and traction
will be lost.Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
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 REVERSE. Back slowly down the hill,
allowing the compression braking of the engine to help
regulate your speed. If the brakes are required to control
vehicle speed, apply them lightly and avoid locking or
skidding the tires.
5
STARTING AND OPERATING 437

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 care-
fully 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 Downhill
Shift 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 transmis-
sion whenever possible.
After Driving Off-Road
Off-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.
