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) or the Enhanced Traction System (ETS), it will improve your ability to accelerate when driving on a slippery road. Even though your vehicle has a traction system you will want to slow down and adjust your driving to the road conditions. Under certain conditions, you may want to turn the TCS or ETS 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 292 or Enhanced Traction System (ETS) on page 293. If you do not have TCS or ETS, 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 289. This system improves your vehicle's stability when you make a hard stop on a slippery road. Whether you have ABS or not, you will want to begin stopping sooner than you would on dry pavement. Without ABS, if you feel your vehicle begin to slide, let up on the brakes a little. Push the brake pedal down steadily to get the most traction you can. Remember, unless you have ABS, if you brake so hard that your wheels stop rolling, you will just slide. Brake so your wheels always keep rolling and you can still steer. • Whatever your braking system, allow greater following distance on any slippery road. • Watch for slippery spots. The road might be fine until you hit a spot that is covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun cannot reach, such as 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 are actually on the ice, and avoid sudden steering maneuvers. 313

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) or
the Enhanced Traction System (ETS), it will
improve your ability to accelerate when driving on
a slippery road. Even though your vehicle has a
traction system you will want to slow down and
adjust your driving to the road conditions. Under
certain conditions, you may want to turn the TCS or
ETS 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 292
or
Enhanced Traction System (ETS)
on page 293
.
If you do not have TCS or ETS, 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 289
. This system improves your
vehicle’s stability when you make a hard stop on a
slippery road. Whether you have ABS or not, you
will want to begin stopping sooner than you would
on dry pavement. Without ABS, if you feel your
vehicle begin to slide, let up on the brakes a little.
Push the brake pedal down steadily to get the most
traction you can.
Remember, unless you have ABS, if you brake so
hard that your wheels stop rolling, you will just
slide. Brake so your wheels always keep rolling
and you can still steer.
Whatever your braking system, allow greater
following distance on any slippery road.
Watch for slippery spots. The road might be
fine until you hit a spot that is covered with ice.
On an otherwise clear road, ice patches may
appear in shaded areas where the sun cannot
reach, such as 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 are
actually on the ice, and avoid sudden steering
maneuvers.
