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.
I 1. 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.

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

the cap again and look at the fluid level on the dipstick.
When the engine compartment is hot, the level
When the engine compartment is cool, the level

“HOT” mark.
should be at the “FULL COLD” mark. Refer
to the Maintenance Schedule
to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index.
234

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 Pa).
How tco 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. 1
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. 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.

Introduction
A Word About Maintenance
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 will
find in the schedules in this part.
So please read this part
and note how you drive. If you have any questions on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners choose to
have their maintenance work done.
Your dealer can be
relied upon to use proper parts and practices.
266

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.
A CAUTION:
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. 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.

“Section D: Recommended Fluids and Lubricants” lists Section A: Scheduled Maintenance
some products GM recommends to help keep your
vehicle properly maintained. These products,
or their Services
equivalents, should be used whether you do the work
yourself
or have it done. Using Your Maintenance Schedules
“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. 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
0
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.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended unleaded fuel. See “Fuel”
in
the Index.
