conditions. Damage may result
from excessive wheel spinning,
including tire, transmission, and/
or rear axle malfunction.
If the vehicle gets stuck and it is
difficult to get out, immediately
stop driving and have the vehicle
towed.
If the vehicle gets stuck in sand,
mud, snow or ice, move the selector
lever from 2 to the R position. 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 driving through deep
mud, using tire chains is an effective
way to avoid getting stuck.
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
get out.
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 debris.
The vehicle speed sensors are fitted
on the wheels. When removing mud
and other debris, take great care not
to damage the components.
Do not use a sharp implement to
remove mud. Sharp edges could
damage rubber parts.
Refer to Antilock Brake System
(ABS) 0 216 and Exterior Care
