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 this section.
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.
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).
