Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the tires
and the road, you can have a very slippery
situation. You will have a lot less traction, or grip,
and will need to be very careful.
What is the worst time for this? Wet ice. Very cold
snow or ice can be slick and hard to drive on.
But wet ice can be even more trouble because it
may offer the least traction of all. You can get
wet ice when it is about freezing, 32°F (0°C), and
freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition — smooth ice, packed,
blowing, or loose snow — drive with caution.

StabiliTrak improves your ability to accelerate
when driving on a slippery road. Even with
®
StabiliTrak , you will want to 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
when driving through deep snow and loose
gravel, to help maintain vehicle motion at lower
speeds. See StabiliTrak
If Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 360.
