Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve
the fuel as long as you can. To help keep warm, you
can get out of the vehicle and do some fairly vigorous
exercises every half hour or so until help comes.
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 transaxle or other parts of
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 transaxle back
and forth, you can destroy your transaxle. See
Rocking Your Vehicle to Get It Out on page 4-31.
For information about using tire chains on your vehicle,
see Tire Chains on page 5-72.
