vary, depending on the type of driving
you do and the weather conditions.. If
"you drive for a long time, such as on a
trip, the gage will show a higher reading-
than
if you had driven for only a short
time. And if it's hot -outside, the-reading
will be higher than if it were cold outside.
If your oil temperature approaches the
shaded area and stays there for some
time; your oil temperature is too high.
Check
the engine oil levei and bring
your vehicle in for service.
You should
also check the engine coolant temperature.
If your engine is to.0 hot, see the.Index

Driving a Long Distance
Although most long trips today are
made on freeways, there are still many
made
on regular highways.
Long-distance driving
on freeways and
regular highways is the same in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there are
longer turns behhd the wheel. You’ll
enjoy your
trip more if you and your
vehicle
are in good shape. Here are
some.fips for
a successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested.
If you must start when you’re
not fresh-such as after
a day’s work-
don’t plan to
make too many miles that
first part of the journey. Wear
comfortable clothing and shoes you
can
easily drive in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready to
go. If it needs service, have it
done before starting
out. Of course,
you’ll find experienced and able service
experts in Chevrolet dealerships all
across North America. They’ll be ready
and willing to help if you need it. Here
&e some
things you can check
before
a trip:

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
On She Road
Uidess you are the -only driver, it is good
to share the driving task with others.
Limit turns behind
the wheel to about
100 miles (160 km) Or two hours at a
sitting.-Then, either change drivers ar
stop for some rdreshment like coffee,
tea or
soft drinks and some limbering
up.
But do stop and move around. Eat
lightly along the way. Heavier meals
tend to
mdke some people sleepy.
On two-lane highways or
undivided
multilane highways that do not have
controlled .access,.you’ll
wmt to watch
for some situations :not usustlly found
on freeways. Examples: are: stop signs
and signals, shopping tenters with
direct access
to the highway, no passing
zones and school zones, vehicles
turning
le& and- right off the-road,
pedestrians, cyclists, parked vehicles, and even a&&.
Highway Hypnosis
Is thete-actually such a condition as
“highway hypnosis”? Or
is it just plain
falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or
whatever.
There is
something about an easy
stretch
of road with the same scenery,
along with the
hum of the tires on the
road, the drone of the engine; and the
rush of the wind against the vehicle that
can make you sleepy. Don’t let it
happen
to you! If it does, your vehicle
can leave the road in less than a
second, and you could crash and be
injured.
What can you do about highway
hypnosis? First, be aware that it can
happen.
Then here
are some tips:
4 Make sure your vehicle is well
ventilated,
with a comfortably cool
interior.
Keep your eyes moving. Sca.n the road
ahead and
-to the sides. Check your
rearview mirrors frequently and your
instruments from time to time. This
can help you avoid
a fixed stare.
Wear good sunglasses in bright light.
Glare can cause drowsiness. But
don’t
wear sunglasses at night. They will.
drastically reduce-your,overall.~sion
at the very time you need all the.
seeing power
you have.
If you get sleepy, pull off the road into
a rest, service, &‘parking area and
take a nap, get so.me exercise, or both.
For safety, treat drowsiness on the
highway
as an emergency.
As in any driving situation, keep pace
with traffic and allow adequate
foIlowing distances.

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.
You can also write us at ,the following
address
for advice. Just tell us where
you're
going and give your Vehicle

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.
