{CAUTION
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will
have to do all the work of
slowing down and they could
get so hot 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
Here are some tips for winter driving:
Have your vehicle in good shape
for winter.
You might want to put winter
emergency supplies in your
vehicle.
Include an ice scraper, a small
brush or broom, a supply of
windshield washer uid, a rag,
some winter outer clothing, a small
shovel, a ashlight, a red cloth,
and reective warning triangles.
And, if you will be driving under
severe conditions, include a small
bag of sand, a piece of old carpet, or
a couple of burlap bags to help
provide traction. Be sure you
properly secure these items in
your vehicle.
Also seeTires on page 9-39.
