Engine Coolant Heater (Engine Block Heater) (Canada Only)
In very cold weather, 0°F (-18°C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged
in a minimum of
four hours prior to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.
I NOTICE:
After you’ve used the coolant heater, be sure to
store the cord
as it was before to keep it away
from moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the weather, the kind
of oil
you have, and some other things. Instead of trying to list
everything here, we ask that you contact a Buick dealer
in the area where you’ll be parking your vehicle. The
dealer can give you the best advice for that particular
area.

I NOTICE:
If you keep driving your vehicle with this light on,
after a while the emission controls won’t work as
well, your fuel economy won’t be as good and your engine may not run as smoothly. This could
lead to costly repairs not covered by your
warranty.
Engine Oil Pressure Light
OIL
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come
on when
you are driving. Stop your
car and shut off
the engine
if this light stays on. This
indicates that oil is not
going through your engine
quickly enough to keep
it
lubricated. The engine
could be low
on oil, or could have some
other oil problem. Have.your vehicle serviced
immediately.
The oil light could also come on in three other
situations:
0
0
0
When the ignition is on but the engine is not running,
the light will come on as a
test to show you it is
working, but
the light will go out when you turn the
ignition to “Start.” If
it doesn’t come on with the
ignition on,
you may have a problem with the fuse or
bulb. Have
it fixed right away.
Sometimes when the engine is idling at a stop, the
light may blink on and
off. This is normal.
If you make a hard stop, the light may come on for
a
moment. This is normal.

Battery Light
Then it should go out. If it stays on, or corn-es 6n %bile
you are driving, you may have a problem with the
electrical charging system. It could indicate that
you
have a loose generator drive belt or another electrical
problem. Have
it checked right away. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on, be
certain
to turn off all your accessories, such as the radio

Care of Your Cassette Tape Player
I P
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 cause failure
of the tape player.
Your tape player should be cleaned regularly each month
or after every
15 hours of use. If you notice a reduction in
sound quality, try a known good cassette to see
if the tape
or
the tape player is at fault. If this other cassette has no
improvement in sound quality, clean the tape player. Clean your tape player with
a wiping-action,
non-abrasive
cleaning cassette, and follow the directions provided with it.
Cassettes are subject
to wear and the sound quality may
degrade over time. Always make sure that the cassette
tape is
in good condition before you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust.
If the surface of a disc is soiled, dampen a
clean, soft cloth in
a mild, neutral detergent solution and
clean it, wiping only from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of
the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever become
slightly bent, you can straighten
it out by hand. If the
mast is badly bent, as it might be by vandals,
you should
replace
it.
Check every once in a while to be sure the mast is still
tightened to the fender.

Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape?
Fuel. Engine Oil. Other Fluids: Have you checked all
levels?
Lights: Are they all working? Are the lenses clean?
0 Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
0 Weather Forecasts: What’s the weather outlook along
your route? Should you delay your trip a short time
to avoid
a major storm system?
0 Maps: Do you have up-to-date maps?
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
injured.
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.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 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.

Parking on Hills
You really should not park your vehicle, with a trailer
attached, on
a hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your,vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
“P”
(Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb
the load.
4. Reapply the regular brakes. Then, apply your
parking brake, and then shift to
“P” (Park).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each of these
is covered in this manual, and the Index
will help
you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
The coolant level should be at or above the
“FULL
HOT” mark.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else
in
the cooling system.
