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'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; O O 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 Enhanced Traction System, keep the
transaxle shift lever in the AUTOMATIC OVERDRIVE
(D) position so the system will be able to operate. It will
improve your ability to accelerate when driving on a
slippery road. Even though your vehicle has this system,
you'll want io slow down and adjust your driving to
the road conditions. See Enhanced Traction
System (ETS) on page 4-8.
