Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
I NOTICE:
Before you add any sound equipment to your
vehicle
-9 like a tape player, CB radio, mobile
telephone or two-way radio
9- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, radio or other systems, and
even damage them. Your vehicle’s systems may
interfere with the operation
of sound equipment
that has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat.
If they aren’t, they may not operate
properly or may cause failure
of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN or
CLEAN TAPE to indicate that you have used your tape
player for
50 hours without resetting the tape clean
timer.
If this message appears on the display, your
cassette tape player needs to be cleaned. It will still play
tapes, but you should clean it as soon as possible to
prevent damage to your tapes and player. If you notice a
reduction in sound quality,
try a known good cassette to
see if it is the tape or the tape player at fault.
If this other
cassette has no improvement
in sound quality, clean the
tape player.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head
as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealership
(GM Part No. 12344789).

Downloaded from www.Manualslib.com manuals search engine Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
Since you can’t see as well, you may need to slow
down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
0 In remote areas, watch for animals.
If you’re tired, pull off the road in a safe place
and rest.
Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase.
A 50-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you’re
driving, don’t wear sunglasses at night. They may cut
down
on glare from headlamps, but they also make a lot
of things invisible. You
can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside 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. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps 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 headlamps 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 li,ght -- and
aren’t even aware of it.

Downloaded from www.Manualslib.com manuals search engine City Driving Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get
a city map and plan your trip into an
unknown part of the city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)
One
of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals.
Treat a green light as a warning signal. A traffic
light is there because the comer is busy enough to
need it. When
a light turns green, and just before you
start to move, check both ways for vehicles that have
not cleared the intersection or may be running the
red light.

Downloaded from www.Manualslib.com manuals search engine Freeway Driving
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most
of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At
the entrance, there is usually a ramp that leads to the
freeway.
If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try
to determine where you expect to
blend with the flow.
Try to merge into the gap at close to
the prevailing speed. Switch on your turn signal, check
your mirrors and glance over your shoulder
as often as
necessary. Try to blend smoothly with the traffic flow.
Once you
are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it’s slower. Stay
in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before
you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect
to move
slightly slower at night.
When you want to leave the freeway, move to the proper lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.

Downloaded from www.Manualslib.com manuals search engine Checking Coolant
L
The surge tank is located next to the engine block on the
passenger's side of the engine.
The cooling system is under a lot of pressure when it is
hot.
If the CHECK COOLANT LEVEL message
appears on the Driver Information Center (DIC), you
will need to add coolant.
l'brning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow
out and burn you badly.
Never turn
the surge tank pressure cap -- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be
at the
FULL COLD mark, which is 2.5 inches (6.4 cm)
below the base
of the fill neck. Use a flashlight as
necessary to
see into the tank.
