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.

5.
Apply your regular brakes, but don’t shift into “P’
(Park) yet.
Have someone place chocks under the trailer 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 then shift to “P” (Park).
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
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.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper Buick Service Manual. It tells you
much.more about how to service your Buick than this
manual can.
To order the proper service manual, see
“Service Publications” in the Index.
I A CAUTlvN:
You can be injured if you try to do service work
on a vehicle without knowing enough about it
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts ancI
other fasteners. “English” and “metric”
fasteners
can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
You should keep a record with all parts receipts and list
the mileage and
the date of any service work you
perform. See “Maintenance Record” in the Index.

service station or a local recycling center for help.
Air Cleaner
The air cleaner is in the right front area of the engine
compartment.
I A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air,
it stops flame if the
engine backfires. If it isn’t there, and
the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.

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 a 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,
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.
0 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
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 (lO°C), you may have
to drive longer.
To check the fluid level:
Park your vehicle on a level place.
