If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.
{ CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the vehicle can overheat. That
could cause an engine compartment fire or
other damage. When you are stuck, spin the
wheels as little as possible. Do not 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 transmission
back and forth, you can destroy your transmission.
For information about using tire chains on your
vehicle, see Tire Chains on page 5-70.
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 you have
a four-wheel-drive vehicle, shift into 4HI. If you have
traction control, turn the traction control system off.
See Traction Control System (TCS) on page 4-9.
Then shift back and forth between REVERSE (R) and a
forward gear, or with a manual transmission, between
FIRST (1) or SECOND (2) and REVERSE (R), spinning
the wheels as little as possible. Release the accelerator
pedal while you shift, and press lightly on the
accelerator pedal when the transmission is in gear.
By slowly spinning your wheels in the forward and
reverse directions, you will cause a rocking motion that
may free your vehicle. If that does not get you out
after a few tries, you may need to be towed out. Or, you
can use your recovery hooks if your vehicle has them.
If you do need to be towed out, see Towing Your Vehicle
on page 4-50.
