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’ll have a lot less traction or “grip” and will need 
to be very careful.

What’s 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’s 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, keep the system on. It will
improve your ability to accelerate when driving on a
slippery road. But you can turn the traction 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 “Rocking Your Vehicle” in the Index. Even though
your vehicle has a traction system, you’ll want to slow
down and adjust your driving to the road conditions. 
See “Traction Assist System” in the Index.

If you don’t have a traction system, accelerate gently.
Try not to break the gentle traction. If you accelerate 
too fast, the drive wheels will spin and polish the surface
under the tires even more.
