QUADRA-TRAC I OPERATING
INSTRUCTIONS/PRECAUTIONS —
IF EQUIPPED
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which enables on-demand four-wheel
drive with active torque management. No driver interac-
tion is required. The Brake Traction Control (BTC) sys-
tem, which combines standard ABS and Traction Con-
trol, 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 condi-
tions where 4WD LOW range is recommended
page 167.
QUADRA-TRAC II OPERATING
INSTRUCTIONS/PRECAUTIONS —
IF EQUIPPED
The Quadra-Trac II system comes equipped with a
customer-selectable electronically operated on-demand
transfer case with active torque management in all
driveable ranges. This transfer case provides the follow-
ing operating range positions:
•
4WD HI
•
N (NEUTRAL)
•
4WD LOW
When additional tractive effort and torque are required,
the 4WD LOW position can be used. 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 normal
4WD HI position at a given road speed. Take care not to
overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect performance
and function of the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the N
(NEUTRAL) position without first fully engaging the
parking brake. The transfer case N (NEUTRAL) posi-
tion disengages both the front and rear drive shafts
from the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is not
in the vehicle.
SHIFT POSITIONS
For additional information on the appropriate use of
each four-wheel drive system mode position, see the
following:
4WD HI
This is the default operating range for daily use.
N (NEUTRAL)
This range disengages the driveline from the pow-
ertrain. It is used for towing your vehicle behind another
vehicle
page 163.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the N
(NEUTRAL) position without first fully engaging the
parking brake. The transfer case N (NEUTRAL) posi-
tion disengages both the front and rear drive shafts
from the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is not
in the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides
an additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph
(40 km/h).
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 and the
engine running, shift the transmission into NEUTRAL
(N), push and hold the 4WD LOW button until the 4WD
LOW Indicator Light begins to flash in the instrument
cluster. When the shift is complete, the 4WD LOW Indi-
cator Light will remain on solid.
