The cassette tape is broken. (Check to see if your
tape
is broken. Try a new tape.)

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops.
Your brakes will wear out much faster if you
do a lot
of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate
a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may
take longer to stop and the brake pedal
will be harder to push. Your
vehicle has anti-lock brakes
(ABS). ABS is an
advanced electronic braking system that will help
prevent a brakmg skid.
When you start
your engine and begin to drive away,
your anti-lock brake system
will check itself. You may
hear a momentary motor
or clicking noise while this test
is going on, and
you may even notice that your brake
pedal moves
a little. This is normal.
ANTI -
LOCK
If there‘s ;I problem with the
anti-lock
brake system, this
warning light will stay on.

System Warning Light” in

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 nuke 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 sufkr from night
blindness
-- the inability to see in dim light -- and
aren’t even aware of it.

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
traffk signals. 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 fieeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next
part, “Freeway Driving.”)
Treat a green light
as a warning signal. A traffic
light is there because
the corner 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 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.
B.efore 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 A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the Delco Freedom‘ battery
installed in every new
GM vehicle. Rut if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could
be present.
Battery
fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes
or on your skin, flush the place with
water and get medical help immediately.
6. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could also be damaged.
Before
you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to an unpainted
metal engine part or a body metal surface. Don’t
connect positive
(+) to negative (-) or you will get a
short that would damage the battery and maybe other
parts, too. Also don’t connect negative
(-) to
negative
(-).
I A CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands
away from moving parts
once the engines are running.

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 DIC, you will need to add coolant.
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.
