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.

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.
