1993 CHEVROLET ASTRO PASSENGER headlights

Downloaded from www.Manualslib.com manuals search engine On a freeway, use your high beams only in remote areas where you won’t
impair approaching drivers, In some places, like cities, using high beams is
illegal.
When you follow another vehicle on a freeway or highway, use
low beams.
True, most vehicles now have day-night mirrors that enable the \
driver to reduce glare. But outside mirrors are not of this type and hi\
gh beams from
behind can bother the driver ahead.
A Few More Night Driving Suggestions
Keep your windshield and all the glass on your vehicle clean-i\
nside and out.
Glare at night is made much worse by dirt on the glass. Even the inside
of
the glass can build up a film caused by dust. Tobacco smoke also makes
inside glass surfaces very filmy and can be a vision hazard
if it’s left there.
Dirty glass makes lights dazzle and flash more than clean glas\
s would,
making the pupils
of your eyes contract repeatedly. You might even want to
keep a cloth and some glass cleaner in your vehicle if you need to clean
your glass frequently.
Remember that your headlights light up far less of a roadway when you are
in a turn or curve.
Keep your eyes moving; that way, it’s easier to pick out dimly lighted objects.
Just as your headlights should be checked regularly for proper \
aim,
so should
your eyes be examined regularly. Some drivers suffer from night\
blindness-the inability to see in dim light-and aren’t even aware of it.

or other vehicles, and raindrops “dimple” the water’s s\
urface, there could be
hydroplaning. Hydroplaning usually happens at higher speeds. There just isn’\
t a hard and
fast rule about hydroplaning. The best advice
is to slow down when it is
raining, and be careful.
Some Other Rainy Weather Tips
Turn on your headlights-not just your parking lights-to help ma\
ke you more visible
to others.
Look for hard-to-see vehicles coming from behind. You may want to use
your headlights even
in daytime if it’s raining hard.
Besides slowing down, allow some extra following distance. And \
be
especially careful when you pass another vehicle. Allow yourself\
more
clear room ahead, and be prepared
to have your view restricted by road
spray.
If the road spray is so heavy you are actually blinded, drop back.
Don’t pass until conditions improve. Going more slowly is be\
tter than
having an accident.
Use your defogger
if it helps.
Have good tires with proper tread depth. (See “Tires” in\
the Index.)
Driving in Fog, Mist and Haze
I ~
AN459007
Fog can occur with high humidity or heavy frost. It can be so mild that you
can see through
it for several hundred feet (meters). Or it might be so thick
4-28

Downloaded from www.Manualslib.com manuals search engine that you can see only a few feet (meters) ahead. It may come suddenly to
an otherwise clear road. And it can be a major hazard.
When you drive into a fog patch, your visibility will be ieduced quickly. The
biggest dangers are striking the vehicle ahead
or being struck by the one
behind. Try
to “read” the fog density down the road. If the vehicle ahead
starts
to become less clear or, at night, if the taillights are harder to see, the
fog is probably thickening. Slow down to give traffic behind y\
ou a chance
to
slow down. Everybody then has a better chance to avoid hitting the vehicle
ahead.
A patch of dense fog may extend only for a few feet (meters) or for miles
(kilometers); you can’t really tell while you’re in
it. You can only treat the
situation with extreme care.
One common fog condition-sometimes called mist
or ground fog-can
happen in weather that seems perfect, especially at night
or in the early
morning in valley and low, marshy areas. You can be suddenly enveloped in
thick, wet haze that may even coat your windshield. You can often spot these
fog patches
or mist layers with your headlights. But sometimes they can be
waiting for you as you come over a hill
or dip into a shallow valley. Start
your windshield wipers and washer,
to help clear accumulated road dirt. Slow
down carefully.
Tips on Driving in Fog
If you get caught in fog, turn your headlights on low beam, even\
in daytime.
You’ll see-and be seen-better. Use your fog lights
if your vehicle has them.
Don’t use your high beams. The light will bounce
off the water droplets that
make up fog and reflect back at you.
Use your defogger. In high humidity, even a light buildup of moisture on the
inside
of the glass will cut down on your already limited visibility. Ru\
n your
windshield wipers and washer occasionally. Moisture can build up\
on the outside glass, and what seems to be fog may actually be moist\
ure on the
outside of your windshield.
Treat dense fog as an emergency.
Try to find a place to pull off the road. Of
course you want
to respect another’s property, but you might need to put
something between you and moving vehicles-space, trees, telephone poles,
a private driveway, anything that removes you from other traffi\
c.
If visibility is near zero and you must stop but are unsure whether you are
away from the road, turn your lights on, start your hazard warning flashers,
and sound your horn at intervals
or when you hear approaching traffic.

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will s\
top until the
motor cools. If the overload is caused by some electrical prob\
lem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd other power
accessories. When the current load is too heavy, the circuit b\
reaker opens
and closes, protecting the circuit until the problem is fixed
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by \
an in-line fuse
in the battery feed wire. This fuse is near the junction bloc\
k. See “Trailer
Wiring Harness” in the Index.
Fuse Block
K3629
The fuse block is under the instrument panel on the driver’\
s side. You can
remove the cover with
a screwdriver and then remove fuses with a fuse
extractor. To remove fuses
if you don’t have one, hold the end of the fuse
between your thumb and index finger and pull straight out.
