Driving and Operating

9-9

WARNING (Continued)

that they would not work well.
You would then have poor braking
or even none going down a hill.
You could crash. Always have the
engine running and the vehicle in
gear when going downhill.

.

Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in
your own lane.

.

Top of hills: Be
alert — something could
be in your lane (stalled car,
accident).

.

Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.

Winter Driving

Driving on Snow or Ice

Drive carefully when there is
snow or ice between the tires
and the road, creating less traction
or grip. Wet ice can occur at about
0°C (32°F) when freezing rain
begins to fall, resulting in even less
traction. Avoid driving on wet ice or
in freezing rain until roads can be
treated with salt or sand.

Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating
too quickly causes the wheels to
spin and makes the surface under
the tires slick, so there is even less
traction.

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.

The Antilock Brake System (ABS)
on page 9‑29
improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.

Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain
icy when the surrounding roads
are clear. Avoid sudden steering
maneuvers and braking while
on ice.

Turn off cruise control on slippery
surfaces.
