The StabiliTrak System on page 4-6 improves the
ability to accelerate on slippery roads, but slow down
and adjust your driving to the road conditions. When
driving through deep snow, turn off the traction control
®
part of the StabiliTrak System to help maintain
vehicle motion at lower speeds.
The Antilock Brake System (ABS) on page 4-5 improves
vehicle stability during hard stops on a slippery roads,
but apply the brakes sooner than when on dry
pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface
of a curve or an overpass can remain icy when
the surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.

Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use the Roadside Assistance Program on page 7-7. To
get help and keep everyone in the vehicle safe:
•
Turn on the Hazard Warning Flashers on page 3-6.
•
Tie a red cloth to an outside mirror.
CAUTION:
{
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
•
Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
•
Check again from time to time to be sure
snow does not collect there.
