Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer-and more enjoyable. (See "Off-Road
Driving" in the Index
for information ab.out driving
off-road.)
Keep your vehicle in good shape; Check all fluid
levels and
also the brakes, tires, cooling system and
transmission. These pqrts
@a work hard on
mountain roads.
Know how to go down hills. The most important
thing
to 'know is this: let: your engine do. some of the
slowing. down. Shift
-to a lower gear when you go
down
a steep or long hill.
If you .don't shift down, your brakes could get
so hot that,they wouldn't work well. You would
then have
po.or braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes .on a steep
downhill
slope.
I
Coasting downhill in NEUTRAL (N) or WILII the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn't work wen. You would then
have poor braking
or even none going down a hill.
You could crash. Always have your enbe running
and your vehicle in gear when you go downhill.
Know how to go uphill. You may want to-shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads
in hills- or mountains. Don't swing wide or cut I
across the center-of the road, Drive at speeds that let
-you stay in your own lane.
As YOU go over the top of--a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
YQU may see highway signs an mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.
