QUADRA-TRAC I® FOUR-WHEEL DRIVE
Quadra-Trac I® Operating 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.

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).
