What to Add:
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only.
DOT-5 silic

0 Don’t let someone put in the wrong kind o
fluid. For example, just a few drops of
mineral-based oil, such as engine
oil, in
your brake system can damage brake

Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good braking. Vehicles
we design and test have top-quality GM brake
parts in them, as your Buick does when it is new. When
you replace parts of your braking system -- for example,
when your brake linings wear down and you have to
have new ones put in
-- be sure you get new genuine
GM replacement parts.
If you don’t, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change,
for the worse. The braking performance you’ve come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
Battery
Every new Buick has a Delco Freedoms battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedoms
battery. Get one that has the catalog number shown
on
the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, take
off the black, negative (-) cable from the
battery. This will help keep your battery from running
down.

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.
I
A CAUTION:
Rust or dlrt on a wheel, or on the parts to which
it is fastetfed, can make wheel nuts become
loose after a time. The wheel could come off and
cause
an accident. When you change a wheel,
remove any rust or dirt from places where the
wheel attaches
to the vehicle. In an emergency,
you can use a cloth or a paper towel to do this;
but be
sure to use a scraper or wire brush later, if
you need to, to get all the rust or dirt off. (See
“Changing a FI; Tire’* On the Index.)

KEEP ENGINE OIL AT THE PROPER

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.
