Rocking Your Vehicle To Get It
Out
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.
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
5-65.
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 or 4L0. If
your vehicle has the Traction Assist System, you should
turn it off by pressing the TAS on/off button. If your
vehicle has the Stabilitrak@System, turn the system off
by pressing the Stabilitrak@button so that the
STABILITY SYS DISABLED message and the traction
off light are illuminated
on
the instrument panel
cluster. 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
your wheels in the forward and reverse directions, you
will cause a rocking motion that may free your
vehicle. If that doesn't 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 4-48.
