Driving and Operating

.

Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.

Remember: Antilock brakes help
avoid only the braking skid.

Off-Road Driving

Four-wheel-drive vehicles can be
used for off-road driving. Vehicles
without four-wheel drive and
vehicles not equipped with All
Terrain (AT) or On-Off Road (OOR)
tires must not be driven off-road
except on a level, solid surface. To
contact the tire manufacturer for
more information about the original
equipment tires, see the Limited
Warranty and Owner Assistance
Information manual.

Controlling the vehicle is the key to
successful off-road driving. One of
the best ways to control the vehicle
is to control the speed.

WARNING

When driving off-road, bouncing
and quick changes in direction
can easily throw you out of
position. This could cause you to
lose control and crash. You and
your passengers should always
wear safety belts.

Before Driving Off-Road

and service work completed.

Fuel the vehicle, fill fluid levels,
and check inflation pressure in

flow to the engine. Re‐attach the
