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 “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.

properly disposing of your used oil, ask your dealer, a
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.
I
Refer to the Maintenance Schedule to determine when
to replace the air filter.
See “Scheduled Maintenance Services’’ in the Index.

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.

lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in “P” (Park).
0 Let the engine run at idle for three to five minutes.

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 kPa).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell
you the pressure, especially if you have radial tires --
which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back
on.
They help prevent leaks by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended
in the
Maintenance Schedule. See “Scheduled Maintenance
Services”
in the Index.
I
I‘
Use this rotation pattern.
After the tires have been rotated, adjust the front and
rear inflation pressure
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in the
Index.

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal of important components can significantly
affect the quality of the air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle. To help protect
our environment, and to help keep your vehicle in
good
condition, please maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section
A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.

le seriously injured.
Do your own maintenanc
work only if you have the required know-how and
:he proper tools and equipment for the job.
If you
have any lubt, have a qualified technic’
1 do
the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information GM publishes. You
will find a list of
publications and how to get them
in this manual. See
“Service Publications”
in the Index.
“Section B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Section
C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.

ProCarManuals.com

“Section D: Recommended Fluids and Lubricants” lists
some products GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Section
E: Maintenance Record” provides a place for
you to record the maintenance performed
on your
vehicle. Whenever
any maintenance is performed, be
sure to write it down in this section. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.
