FOUR-WHEEL DRIVE OPERATION
MP3022 Selec-Trac II Transfer Case
Operating Information and Precautions
The Selec-Trac II active on-demand transfer
case provides four positions:
• Two-wheel drive (2WD) high range
• Four-wheel drive Auto (4WD AUTO) high
range
• Neutral (N)
• Four-wheel drive (4WD LOW) low range
This transfer case is intended to be driven in
either the two-wheel drive position (2WD) or the
four-wheel drive Auto position (4WD AUTO) for
normal street and highway conditions such as
dry hard-surfaced roads.
For added capability when traversing steep
grades, rough terrain, or extremely poor trac-
tion surfaces, select the transfer case 4WD
LOW position. This position locks the front
driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the
same speed while multiplying engine torque.
Use the transfer case NEUTRAL position for
recreational towing only. Refer to "Recreational
Towing" in "Starting and Operating" for further
information.
CAUTION!
• The 4WD LOW position is intended for
loose or slippery road surfaces only. Driv-
ing in this position on dry hard-surfaced
roads may cause increased tire wear and
damage to the driveline components.
• When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the 2WD position or 4WD
AUTO position at a given road speed. Take
care not to over-speed the engine and do
not exceed 25 mph (40 km/h).
• Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type,
and circumference on each wheel. Any
difference in tire size can cause damage to
the transfer case. Tire rotation schedule
should be followed to balance tire wear.
WARNING!
• You or others could be injured if you leave
the vehicle unattended with the transfer
case in the NEUTRAL position without first
fully engaging the parking brake. The trans-
fer case NEUTRAL position disengages
both the front driveshaft and rear driveshaft
from the powertrain and it will allow the
vehicle to move despite the transmission
position. The parking brake should always
be applied when the driver is not in the
vehicle.
• Always engage the parking brake when
powering down the vehicle if the "SERV
4WD Warning Light" is illuminated. Not
engaging the parking brake may allow the
vehicle to roll, which may cause personal
injury.
• Since 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. You or
others could be injured.
