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 your vehicle ever gets stuck in sand, mud, ice or
snow. See If You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-45 . 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
(TAS) on page 4-10 .
If you don't have a traction system, 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.
Your anti-lock brakes improve your vehicle's stability
when you make a hard stop on a slippery road.
Even though you have an anti-lock braking system,
you'll want to begin stopping sooner than you would on
dry pavement. See Braking on page 4-6 .
•
Allow greater following distance on any slippery
road.
•
Watch for slippery spots. The road might be fine
until you hit a spot that's covered with ice. On
an otherwise clear road, ice patches may appear in
shaded areas where the sun can't reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass
may remain icy when the surrounding roads
are clear. If you see a patch of ice ahead of you,
brake before you are on it. Try not to brake
while you're actually on the ice, and avoid sudden
steering maneuvers.
