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.

StabiliTrak will improve your ability to accelerate
when driving on a slippery road. But you can
®
turn StabiliTrak off if you ever need to. See
®
StabiliTrak System on page 348 and If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 388. Even with StabiliTrak
slow down and adjust your driving to the road
conditions. Under certain conditions, you may want
®
to turn StabiliTrak off, such as when driving
through deep snow and loose gravel, to help
maintain vehicle motion at lower speeds.
Your Anti-Lock Brake System (ABS) improves
your vehicle's stability when you make a hard stop
on a slippery road. Even though you have ABS,
you will want to begin stopping sooner than
you would on dry pavement. See Anti-Lock Brake
System (ABS) on page 345.
