Hin and Mounfain Roads
Driving on steep hills or mountains is
dif€erent fram driving in flat or rolling
terrain. 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.
Keep your vehicle in good shape. Check
all fluid levels and also the brakes, tires,
cooling system and transmission. These
parts can work hard on mountain roads.
Know how to go down hills. The most
important thing to how is this: Let
your engine do. some of the slowing
'down. Don't make your brakes do it
all. Shift to a lower gear when you go
down .a steep or long hill. That way,
you will slow down without excessive
use of your brake-s.
Know how to go uphill. You may
want to shift dawn to a lower gear.
The lower gems help cool your engine
and transmission, and you can clin-ib
the *f hiU better.
Stay in your own lane when driving
on two-lane roads in hills or
mountains. Don't swing wide .or cut-
across. the .center of the road. Drive at
speeds that-let-you stay 'in your own
lae. That way, you won't be
surprised by,a vehicle- coming toward
you
in the same lane.
* It takes longer to pass another vehicle-
when you're going uphill. You'll want
to leave extra room to pass. If a
vehicle is passing you and doesn't
have enough room, slow down to
make it easier for the other vehicle to
get by.

Tie a red cloth to your vehicle to alert
police that you've been stopped
by the
snow.

Put on extra clothing or wrap a
blanket around you. If you have no
blankets or extra clothing, make body
insulators
from newspapers, burlap
bags, rags, floor mats-anything you
can wrap around yourself or tuck
under
your clothing tu keep warm.

Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lase air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 1tPa). The compact spare is
made to go up to 3,000 miles (5 OOO km),
so you can finish your trip and have
your
full-size tire repaired or replaced
where. you want. Of course, it's best to
replace your .s.parewith .a full-size tire as
soon as you can. Your -spare will last
longer and
be in good shape in case you
need
it again.

'OTIC E
Don't use your compact. spare on some
other vehicle.
And don't mix your compact spare or
wheel with other wheels or tires. They
won't fit. Keep your spare and its -wheel
together.

In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolinesare specially designed
to reduce vehicle emissions. General
Motors recommends that
you use
reformulated gasoline. By doing so, you
can help clean the air, especially in
those parts of the country that have
high ozone levels.
You should.aslc your service station
operators
if their gasolines contain
detergents and oxygenates, and
if they
have been reformulated to reduce
vehicle
emissions.
Fuels in Foreign Countries
If you plan on drivingh another
country outside the
U.S. or Canada,
unleaded
fuel may be hard to find.
Do not use leaded gasoline. If you use
even
one tankful, your emission
controls won't
work well or at all. With
continuous use,
spa& plugs can get
fouled,
the exhaust system can corrode,
and
your engine oil can deteriorate
quickly. Your vehicle's oxygen sensor
will be damaged.
All ofthat means
costly repairs that wouldn't be covered
by
your warranty.
To check on fuel availability, ask an
auto club,
or contact a major oil
cuspany that does business in the
countqrwhere you'll
be driving.

Checking Things Under
the Hood
The following sections tell you how to
check fluids, lubricants and important
parts underhoad.
Hood Release
To open the hood, first pdl the hood
release handle inside the vehicle.
Then lift the rear edge of the hood at
the windshield area.

Downloaded from www.Manualslib.com manuals search engine Underhood Lights
Leaving your hood open and your
underhood lights on can drain your
battery.
If you need to keep the hood
open for an extended period
of time,
remove the Underhood Lights Fuse.
This 1O-amp fuse is located under the
hood on the left-hand marker light
assembly. See the
Index under Fuses &
Circuit Breakers.
Engine Oil
It's a good.idea to check pur engine oil
level every time you get fuel. In order to
get
an accurate reading, the vehicle
must be on level
ground.
If you have the LTl engine, the best
time
to check your engine oil is when
the
engine is warn. If the engine is
mnning, the engine oil won't drain back
into the pan.
Turn off the engine and
give the oil a few minutes to drain back
into the-oil
pan. If you don't, the oil
dipstick might not show the actual
level. If
you have a ZR-1, the best time to
chegk your engine oil is when
the
engine
is cold. If you run the engine, the
engine oil
won't drain back into the pan
fast enough.
Give the oil two hours to
drain
back into the oil pan. If you don't,
the oil dipstick might not
show the
actual level.
