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.
If you have the Traction Control System (TCS) or the
Enhanced Traction System (ETS), it will improve
your ability to accelerate when driving on a slippery
road. 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 TCS or ETS 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 4-9 or Enhanced Traction
System (ETS) on page 4-11.
If you do not have TCS or ETS, 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.
Unless you have the Anti-Lock Brake System (ABS),
you will want to brake very gently, too. If you do
have ABS, see Anti-Lock Brake System (ABS) on
page 4-7. This system improves your vehicle’s stability
when you make a hard stop on a slippery road.
Whether you have ABS or not, you will want to begin
stopping sooner than you would on dry pavement.
