If Your Vehicle Is Stuck In Sand, Mud, Ice, Or Snow - Chevrolet 2007 HH7 Owner's Manual

You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
the headlamps. Let the heater run for a while.
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.
If your vehicle has the Enhanced Traction System
(ETS), the ETS can often help to free a stuck
vehicle. See Enhanced Traction System (ETS) on
page 246. If the stuck condition is too severe
for the ETS to free the vehicle, turn the ETS off
and use the rocking method.

CAUTION:
{
If you let your vehicle's 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 the wheels can destroy parts
of your vehicle as well as the tires. If you spin
the wheels too fast while shifting the transaxle
back and forth, you can destroy the transaxle.
See Rocking Your Vehicle to Get It Out on
page 269.
