OFF-ROAD CAPABILITIES
• The Quadra-Trac II
transfer case is fully automatic in the
normal driving 4WD HI mode. The
Quadra-Trac II
transfer case provides three mode po-
sitions:
• 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 to-
gether 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 pro-
tection 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).
Shifting Procedures

LOW" indicator light in the instrument cluster will begin to flash and remain on
solid when the shift is complete.
