Driving On Snow Or Ice - GMC Yukon Denali 2003 Owner's Manual

Driving on Snow or Ice

Most of the time, those places where your tires meet
the road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation.
You'll have a lot less traction or "grip" and will need to
be very careful.
What's 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
4-38
the least traction of all. You can get wet ice when it's
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.
Accelerate gently. Try not to break the fragile traction. If
you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
Your anti-lock brakes improve your vehicle's stability
when you make a hard stop on a slippery road.
Even though you have an anti-lock braking system,
you'll want to begin stopping sooner than you would on
dry pavement. See Braking on page 4-6 .
•
Allow greater following distance on any
slippery road.
•
Watch for slippery spots. The road might be fine
until you hit a spot that's covered with ice. On
an otherwise clear road, ice patches may appear in
shaded areas where the sun can't reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass
may 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're actually on the ice, and avoid sudden
steering maneuvers.
