check engine light BUICK REGAL 1993 Owners Manual

When one of the warning lights comes on and stays on
when you are driving,
or when one of the gages shows
there may be a problem, check the section that tells
you
what to do about it. Please follow the manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Fuel Gage
UNLEADEL,

Your fuel gage shows about
how much
fuel is in your
tank. It works
only when
the engine is on. When the
indicator nears
“E,” you
still have a little fuel left.
You need to get more right
away.
Here are
four concerns some owners have had about the
fuel gage. All these situations are normal and indicate
nothing wrong with the
fuel gage.

gage reads

but
it took more -- or less -- than half of the tank’s
capacity
to fill it.
e It takes more (or less) gas to fill up than the gage
e The gage moves a little when you turn a corner,
speed
up, or stop your vehicle.
When
you turn the engine off, the gage doesn’t go all
the
way back to “E”.

Malfunction Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your fuel, ignition
and emission control systems. This light should come
on
when the ignition is on, but the engine is not running, as
a check
to show you it is working. If it does not come on
at all, have it fixed right away.
If it stays on, or it comes
on while you are driving, the computer is indicating that
you have a problem. You should take your vehicle in for
service soon.

AM Stereo
This means the DelcoB system can receive C-QUAM@
stereo broadcasts. Many AM stations around the country
use C-QUAM@
to produce stereo, though some do not.
(C-QUAM@ is a registered trademark
of Motorola, Inc.)
If your Delcoa system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.
A CAUTION:
Hearing damage from loud noise is ZIIH IOSl
undetectable until it is too late. Your hearing can
adapt
to higher volumes of sound. Sound that
seems normal can be loud and harmful
to your
hearing. Take precautions by adjusting the

to a safe sound
level before your hearing adapts to
it.

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.
0 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.
Anti-Lock Brakes (Option)
If your Buick has this system, your Buick has an
advanced electronic braking system that will help
prevent skidding.
If you have an anti-lock brake system (ABS), the brake
pedal will say
so. And this light on the instrument panel
will go
on when you start your vehicle.
When you start your vehicle
and begin to drive away,
you may hear a momentary motor or clicking noise. And
you may even notice that your brake pedal moves a little
while this is going on. This is the
ABS system testing
itself. If you have your foot
on the brake pedal, this
check won’t happen until the vehicle goes about
4 mph
(6 km/h) or until you take your foot off the brake pedal.
After an
ABS stop, you may hear a clicking noise the
next time the vehicle goes about 4 mph (6 km/h).

On two-lane highways or undivided multilane highways
that do not have controlled access, you’ll want to watch
for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers
with direct access to the highway, no passing zones and
school zones, vehicles turning left and right
off the road,
pedestrians, cyclists, parked vehicles, and even animals.
Highway Hypnosis
Is there 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
inj ured.
What can you
do about highway hypnosis? First, be
aware that it can happen. Then
here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan 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
vision at
the very time you need all the seeing power
you have.
If you get sleepy, pull off the road into a rest, service,
or parking area and take a nap, get some 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 following distances.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps
the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.

Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer,
you’ll need to go much farther beyond the
passed vehicle before
you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
firn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lights will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows
on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out.
Thus, you may think drivers
behind you are seeing your signal when they are not.
It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If
you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000
pounds ( 450 kg), and you have an automatic transaxle
with Overdrive, you may prefer to drive in
“D” instead
of Overdrive
(or, as you need to, a lower gear).
