FOUR-WHEEL DRIVE
OPERATION
Quadra-Trac I®Operating
Instructions/Precautions
• 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®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 road 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 “CHECK SHIFT PROCEDURES”
message will flash from the Electronic
Vehicle Information Center (EVIC).
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.

Shifting Procedures
4WD HI To 4WD LOW
• With the vehicle at speeds of 0 to 3 mph(0 to 5 km/h), key ON or engine
running, shift the transmission into
NEUTRAL, and raise the transfer case
T-handle. The “4WD LOW” indicator
light in the instrument cluster will
begin to flash and remain on solid
when the shift is complete. Release the
T-handle.
• 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.
4WD LOW To 4WD HI
• With the vehicle at speeds of 0 to 3 mph(0 to 5 km/h), key ON or engine
running, shift the transmission into
NEUTRAL, and raise the transfer case
T-handle. The “4WD LOW” indicator
light in the instrument cluster will flash
and go out when the shift is complete.
Release the T-handle.
NEUTRAL Shift Procedure
• Key ON, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL.
• Hold down the NEUTRAL “pin” switch
(with a pen, etc.) for four seconds until
the LED light by the switch starts to
blink indicating shift 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.
