FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I Operating Instructions/

Precautions – If Equipped
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.
NOTE: The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to "Off-Road Driving Tips" in "Starting and Oper-
ating" for further information.
Quadra-Trac II Operating Instructions/
Precautions – If Equipped
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 positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the 4WD HI mode.
