If Your Vehicle Is Stuck In Sand, Mud, Ice, Or Snow; Rocking Your Vehicle To Get It Out - GMC 2007 Yukon Denali Owner's Manual

If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
need to spin the wheels, but you do not want
to spin the 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 vehicle's 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 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
transmission back and forth, you can destroy
the transmission.
For information about using tire chains on your
vehicle, see Tire Chains on page 504.

Rocking Your Vehicle to Get It Out

First, turn the steering wheel left and right. That will
clear the area around the front wheels. If your
vehicle has the StabiliTrak
system off. See StabiliTrak
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 transmission is in gear. By slowly spinning
the wheels in the forward and reverse directions,
you will cause a rocking motion that may free your
vehicle. If that does not get your vehicle out after a
few tries, it may need to be towed out. Or, you can
use the recovery hooks. If your vehicle does need
to be towed out, see Towing Your Vehicle on
page 400.
