GMC Envoy - Driving on Snow or Ice

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
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.
If you have traction assist, it will improve your ability to
accelerate when driving on a slippery road. But you
can turn the traction assist system off if you ever need
to. You should turn the system off if your vehicle
ever gets stuck in sand, mud, ice or snow. See If You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-43.
Even though your vehicle has a traction system, you will
want to slow down and adjust your driving to the road
conditions. Under certain conditions, you may want
to turn the traction assist system 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 4-9.
