If You're Stuck: In Sand, Mud,
Ice or Snow
What you don't want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
"rocking" can help you get out when you're stuck, but
you must use caution.
If you let your tires spin
at
high speed, they can
explode, and you or others could be injured. And,
the transaxle
or
other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you're
stuck, spin the wheels as little as possible. Don't
spin the wheels above 35 mph (55 km/h) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see "Tire Chains" in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has the Enhanced Traction System, you should turn
the system off. (See "Enhanced Traction System" in
the Index.) If your vehicle has the Traction Control
System, you should turn the system off. (See "Traction
Control System" in the Index.) Then shift back and forth
between REVERSE (R) and a forward gear, spinning the
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. If that doesn't get
you out
after
a few tries, you may need to be towed out.
If you do need to be towed out, see "Towing Your
Vehicle" in the Index.
