HOW DOES FOUR-WHEEL DRIVE
WORK
Using the 2-Speed Automatic Four-
Wheel Drive System
The 2-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 2-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive auto,
four-wheel drive high, and four-wheel drive
low as available modes of operation. When
you select four-wheel drive auto the system
continuously varies power to the front wheels
for optimum performance for all on-road
conditions. When you select either
four-wheel drive high or four-wheel drive low
with the appropriate drive modes, the
four-wheel drive system provides
electronically locked power to the front and
rear wheels for use in off-road or slippery
conditions such as deep snow, sand or mud.
Selecting four-wheel drive low also provides
additional gearing for increased torque
multiplication for conditions like deep sand,
snow, steep slopes, or pulling heavy objects.
See Selecting a Drive Mode (page 280).
Additionally, the system is capable of
recreational flat towing by putting the
transfer case into neutral (N). See
Recreationally Towing Your Vehicle (page
382).
There is further information on driving in
unique driving conditions. See Driving Hints
(page 370).
FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury and
death.
WARNING: Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting stuck or damaging underbody
components. The differences that make your
vehicle so versatile also make it handle
differently than an ordinary passenger car.
Always maintain steering wheel control,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes. Drive cautiously to avoid
vehicle damage from concealed objects such
as rocks and stumps. Drive slower in strong
crosswinds which can affect the normal
steering characteristics of your vehicle. Be
extremely careful when driving on pavement
made slippery by loose sand, water, gravel,
snow or ice.
