Remove snow that has stuck to the
inside of the fenders and to the
brake hoses. Otherwise, it may
damage components. After driving
on a salted road, wash the
underside of the vehicle as soon as
possible to prevent the salt from
causing rust. Spraying water under
high pressure is an effective way to
get the salt off.
After washing the vehicle, wipe the
door openings dry.
If the Vehicle Is Stuck
When Driving on Bad Roads
Freeing the Vehicle from Sand,
Mud, Snow, and Ice
If your vehicle gets stuck in sand,
mud, snow or ice, move the selector
lever from "Second" to "Reverse".
Apply a light pressure to the
accelerator pedal while the
transmission is in gear. Remove
your foot from the accelerator and
press the brake pedal while shifting.
Do not race the engine. For best
traction, avoid spinning the wheels.
When you cannot avoid drivingthrough deep mud, using tire chains
is an effective way to avoid getting
stuck.
Do not allow wheels to spin freely in
mud, sand, snow, ice or other poor
road conditions. This free spinning
will damage the rear axle. Even
vehicles equipped with LSD (Limited
Slip Differential) have traction
limitations. If your vehicle gets stuck
and it is difficult to extricate,
immediately stop driving and have
the vehicle towed. Spinning wheels
for an extended period of time may
cause abnormal noises or
malfunction to LSD.
Do not spin wheels faster than
32 km/h (20 MPH). Damage may
result from excessive wheel
spinning, including tire, transmission
and/or rear axle malfunction.
When driving in sand or mud, avoid
hard braking, sudden acceleration
and sharp turns of the steering
wheel. Such actions could get the
vehicle stuck and make it difficult to
extricate.
After driving through deep mud: any
mud stuck to the vehicle can harm
the steering, brakes and powertrain.
Wash the vehicle and remove all
mud and other incrustation.
The vehicle speed sensors are fitted
on the wheels. When removing mud
and other incrustation, take great
care not to damage the
components.
Do not use a sharp implement to
remove mud. Sharp edges could
damage rubber parts.
