Chevrolet Silverado Classic 2007 Owner's Manual page 403

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.
If you have the Traction Assist System (TAS), it
will improve your ability to accelerate when driving
on a slippery road. But you can turn the TAS
off if you ever need to. You should turn the TAS
off if your vehicle ever gets stuck in sand,
mud, ice, or snow. See If Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 406. Even
though your vehicle has TAS, you will want to slow
down and adjust your driving to the road
conditions. Under certain conditions, you may
want to turn the TAS off, such as when driving
through deep snow and loose gravel, to help
maintain vehicle motion at lower speeds. See
Traction Assist System (TAS) on page 363.
If you do not have TAS, 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.
