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),
it will improve your ability to accelerate when
driving on a slippery road. But you can turn the
TCS off if you ever need to. You should turn
the TCS 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 160. Even if
your vehicle has TCS, you will want to slow
down and adjust your driving to the road
conditions. Under certain conditions, you may
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 139.
If you do not have TCS, 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 136. ABS improves your vehicle's stability
when you make a hard stop on a slippery road.
