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.

Remove the wing nut and pull off the cover. Remove and replace the filter. Replace the cover,
wing

Refer to the Maintenance Schedule to determine when
to replace the air filter.
See “Scheduled Maintenance Services’’
in the Index.

I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire.
And, dirt can easily get
into your engine, which will damage
it. Always
have the air cleaner
in place when you’re driving.
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.
I NOTICE:
loo 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, starting a fire. Be sure to get
an accurate reading
if you check your transaxle
fluid.

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. 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.

ProCarManuals.com

“Section C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.
“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.
Section A: Scheduled Maintenance
Services
Using Your Maintenance Schedules
This section tells you the maintenance services you
should have done and when you should schedule them.
Your Buick dealer knows your vehicle best and wants
you to be happy with it. If you go to your dealer for your
service needs, you’ll know that GM-trained and
supported service people will perform the work using
genuine GM parts.
These schedules are for vehicles that:
0 carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended unleaded fuel. See “Fuel” in
the Index.
