If You're Stuck: In Sand, Mud, Ice Or Snow - Hummer 2003 H2 Owner's Manual

If You're 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 don't want 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.
CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transmission 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.
5-30
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.
See "Rocking Your Vehicle To Get It Out."
For information about using tire chains on your vehicle,
see "Tire Chains" in the Index.
