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.

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

• 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.
