GMC 2008 Acadia - Manual (Page 290)

StabiliTrak ® improves your ability to accelerate when
driving on a slippery road. Even with StabiliTrak ® , slow
down and adjust your driving to the road conditions.
Under certain conditions, you might want to turn
the traction control part of the StabiliTrak
® System off,
such as when driving through deep snow and loose
gravel, to help maintain vehicle motion at lower speeds.
See StabiliTrak
® System on page 4-6 and If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-20.
The Antilock Brake System (ABS) improves your
vehicle’s stability when you make a hard stop on a
slippery road. Even though you have ABS, begin
stopping sooner than you would on dry pavement. See
Antilock Brake System (ABS) on page 4-5.
• Allow greater following distance on any slippery road.
• Watch for slippery spots. The road might be fine until
you hit a spot that is covered with ice. On an
otherwise clear road, ice patches can appear in
shaded areas where the sun cannot reach, such as
around clumps of trees, behind buildings, or under
bridges. Sometimes the surface of a curve or an
overpass can remain icy when the surrounding roads
are clear. If you see a patch of ice ahead of you,
brake before you are on it. Try not to brake while you
are actually on the ice, and avoid sudden steering
maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with
your vehicle unless you know for sure that you are near
help and you can hike through the snow. Here are
some things to do to summon help and keep yourself
and your passengers safe:
• Turn on the hazard warning flashers.
• Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
• Put on extra clothing or wrap a blanket around you.
If you do not have blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, floor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
