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
have a lot less traction, or grip, and 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 can 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.
The Traction Control System (TCS) improves your ability
to accelerate when driving on a slippery road. TCS
improves your ability to accelerate. See If Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-39. Even
though you have TCS, slow down and adjust your driving
to the road conditions. Under certain conditions, you
might want to turn the TCS off, such as when driving
through deep snow and loose gravel, to help maintain
vehicle motion at lower speeds. See Traction Control
System (TCS) on page 4-5 and StabiliTrak
