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;
0 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.

Engine Oil Additives
Don’t add anything to your oil. Your Buick dealer is
ready to advise
if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
a
a
a
a
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use
a carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle,
then you need to change your oil and filter every
3,000 miles (5 000 km) or 3 months -- whichever occurs
first. (See “Change Oil Soon” Light
in the Index.)
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine
oil to
break down slower.
(See “Change Oil Soon” Light
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, loosen the wing nut
on the
air duct and lift up
on the
two clips located
on the top of the filter
cover, Disconnect the duct
and reposition it while
removing the side cover.

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

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.
Change both the fluid and filter
every 50,000 miles
(83
000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter
do not require changing.
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.
I I
I 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.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for
all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals. When
rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust
the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part 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.
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how
and the proper tools and equipment for the job.
If you have any doubt, have a qualified
technician 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. See “Service and Owner
Publications’’ in the Index.
“Part B: Owner Checks and Services” tells
you what should be checked and when. It also explains
what you can easily do to help keep your vehicle in
good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your Buick dealer’s
service department or another qualified service center
should perform.
“Part 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.
“Part 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 part. 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.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition.
But we don’t know
exactly how you’ll drive
it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time
in very hot, dusty weather.
You may use your vehicle in making deliveries.
Or you may drive it to work, to do errands or
in
many other ways.
Because
of all the different ways people use their
GM vehicles, maintenance needs vary. You may even
need more frequent checks and replacements than
you’ll
find in the schedules in this section. So please read this
section and note how you drive.
If you have any
questions on how to keep your vehicle in good
condition, see your Buick dealer.
This part tells you
the maintenance services you should
have done and when
you should schedule them. 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. The
proper fluids and lubricants to
use are listed in Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before you or anyone else drives the vehicle.
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.
use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:

Maintenance Schedule
Short TripKity Definition
Follow the Short TripKity Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
0 Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle. (With some models, you should never
tow
a trailer. See “Towing a Trailer” in the Index.)
0 If the vehicle is used for delivery service, police, taxi
or other commercial application.
One
of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonel:
