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

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.

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.
