Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The green arrows on your
instrument panel will flash whenever you signal a turn
or lane change. Properly hooked
up, the trailer lamps
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.
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.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet.
Have someone place chocks under the
trailer’s wheels.
When the wheel chocks are
in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and shift
to PARK (P).
Release the regular brakes.

Engine Overheating
You will find a coolant temperature gage and a hot
engine warning light on your instrument panel. See
“Engine Coolant Temperature Gage” and “Engine
Coolant Temperature Warning Light” in the Index. You
also have a low coolant warning light on your
instrument panel. See “Low Coolant Light” in the Index.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see
or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in
it can catch fire. You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine
is cool.

Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Buick dealer before adding equipment
to the
outside
of your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared
to
other gasolines.
Be sure the posted octane is at least
87. If the octane is
less than
87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine. If
you’re using fuel rated
at 87 octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry if
you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel
to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
If your vehicle
is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on
fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn
on and/or
your vehicle may fail a smog-check
test. If this occurs,
return
to your authorized Buick dealer for diagnosis
to determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may
not be covered by your warranty.

Some gasolines that are not reformulated for low
emissions contain
an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used,
spark plug
life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn
on. If this occurs, return to your authorized
Buick dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system
to
function properly. Therefore, you should not have to add
anything
to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area
to
help clean the air. General Motors recommends that you
use these gasolines if
they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it.
It can corrode
metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Hood Release
To open the hood, first pull
the handle inside the vehicle,
located just below the
instrument panel and
to the
left
of the steering column.
Then
go to the front of the vehicle and release the
secondary hood release. Lift the hood.

Before closing the hood, be sure all the filler caps
are on properly. Then just pull the hood down and
close it firmly.
Engine Oil
LOW
OIL
If the LOW OIL light on the
instrument panel comes on,
it means you need to check
your engine oil
level right
away. For more
information, see “Low Oil
Level Light” in the Index.
You should check your
engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground. The engine oil dipstick handle
is the yellow loop near
the front of the engine.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with
a soft cloth. Then, let the
leather dry naturally.
Do not use heat to dry.
0 For stubborn stains, use a leather cleaner. See your
dealer for
this product.
0 Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish
on leather.
Soiled or stained leather should be cleaned
immediately.
If dirt is allowed to work into the
finish, it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make
it difficult to see through the windshield
under certain conditions.
Cleaning the Built-in Child Restraint
Your built-in child restraint may be cleaned with mild
soap
and lukewarm water. Don’t use household cleaners.
They may weaken the harness or damage plastic parts.
The built-in child restraint pad is attached to the child
restraint cushion and seatback with fastener strips. You
can remove the pad, machine wash it in cold water
on a
gentle cycle and tumble dry it
on a low heat setting.
Never bleach or iron the pad, and don’t dry clean it.
