STARTING AND OPERATING 197
NOTE:
The Quadra-Trac I system is not appropriate for
conditions where 4WD LOW range is recom-
mended. Refer to “Off-Road Driving Tips” in
“Starting And Operating” for further informa-
tion.
QUADRA-TRAC II OPERATING
I
NSTRUCTIONS /PRECAUTIONS — IF
E
QUIPPED
The Quadra-Trac II transfer case is fully
automatic in the normal driving 4WD AUTO
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).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause damage
to 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.
SHIFT POSITIONS
For additional information on the appropriate
use of each 4WD system mode position, see the
information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain — If Equipped” in this
chapter for further information on the various
positions and their intended usages.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL position without first
fully engaging the parking brake. The transfer
case NEUTRAL position 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.
