Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
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.
Turn 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 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 Oefbve 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), you may prefer to drive in
THIRD (3) instead of DRIVE (D) (or, as you need to,
a lower gear).

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
PARK
(P) 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 PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a
Hill
I. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
0 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.

6. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before you connect the cables, here are some basic
things you should
know. Positive (+) will go to
positive
(+) and .negative (-) will go to negative (-)
or a metal engine part. Don’t connect (+) to (-) or
you’ll get a short that would damage
the batterv and
maybe other
parts, too.

The coolant level should be at or above the COLD 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.
I A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do,
you can be burned.
Don’t run the engine
i€ there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on check to
see
if the electric engine fan(s) are running. If the engine
is overheating, both fan(s) should be running. If they
aren’t, your vehicle needs service.

8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch
out for the
engine hns.
9. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base of the filler neck.
10. Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the
BI-~OWS on the pressure cap line up like this.
1 1 - Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine
is cold.

Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will
help prevent deposits from forming in your engine and
fuel system. That helps keep your engine in tune and
your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for
cleaner air.
Many gasolines are now blended with oxygenates.
General Motors recommends that
you use gasolines with
these blending materials, such as MTBE and ethanol. By
doing
so, you can help clean the air, especially in those
parts
of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline.
By
doing so, you can help clean the air, especially in those
parts
of the country that have high ozone levels.
You should ask your service station operators
if their
gasolines contain deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business
in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just
tell us where you’re going and give your
Vehicle Identification Number (VIN).

Hood Release
To open the hood, first pull
the handle inside the
vehicle.
Then go to
the front of the
vehicle and release the
secondary hood release. Lift
the hood. Before closing the

Engine Oil
hood down and close it
If the LOW OIL LEVEL
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.

Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0 OF (- 1 8 O C) or
colder. If your vehicle has this option, see “Engine
Coolant Heater” in
the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t
let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing
or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat
to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from
the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies
of water. Instead,
recycle it by taking
it to a place that collects used oil. if
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
To check or replace the air filter, remove the four screws
and pull off the cover.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule
to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Buick dealership
Service Department.
If you do it yourself, be sure
to follow all the instructions
here, or you could get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F (82°C
to
93 ” C).
Get the vehicle warmed up by driving about 15 miles
(24
km) when outside temperatures are above 50°F
(10°C). If it’s colder than 50°F (IOOC), you may have
to drive longer.
To check the fluid level
0 Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in PARK (P).
