Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.
Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to
reduce the risk of an accident or serious
injury.
Four-wheel drive system
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.
A vehicle equipped with four-wheel drive
(when selected) has the ability to use all
four wheels to power itself. This increases
traction which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
Power is suppled to all four wheels through
a transfer case or power transfer unit.
Four-wheel drive vehicles allow you to
select different modes as necessary. For
information on transfer case operation and
shifting procedures, See All-Wheel Drive
(page 170). For information on transfer
case maintenance, See Maintenance
(page 258). You should become thoroughly
familiar with this information before you
operate your vehicle.

Wheels and Tires
On some four-wheel drive vehicles, the
initial shift from two-wheel to four-wheel
drive while the vehicle is moving can cause
a momentary clunk and ratcheting sound.
These sounds are normal and are not
cause for concern.
For four-wheel drive vehicles, a spare tire
of a different size other than the tire
provided should never be used. A dissimilar
spare tire size (other than the spare tire
provided) or major dissimilar tire sized
between the front and rear axles could
cause the four-wheel drive system to stop
functioning and default to front-wheel
drive. See Using All-Wheel Drive (page
170).
