in
PARK (P).
3. With
your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in
PARK (P).
4. Let the engine run at idle for three to five minutes,
Then, without shutting off the engine, follow these steps:
The transaxle dipstick
handle is the red loop
near the back of
the engine.
1. Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. Check both sides of the
dipstick, and read the
lower level: The fluid
level must be in the'
cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.

Brakes
Bri lid
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level
in the
reservoir might go down. The first is that the brake fluid
goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake system fixed, since
a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct
a leak. If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings.
You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
If you have too much brake fluid, it can spill on
the engine. The fluid
will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done
on the brake hydraulic system
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light”
in the Index.

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, and always clean the brake fluid
reservoir cap before removing it.
-
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:
0 Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they'll have to be
replaced. Don't let someone put in the
wrong kind
of fluid.
0 If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it
off
immediately. See "Appearance Care" in
the Index.

Brake Wear
Your Buick has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing on the brake pedal firmly).
A CAUTION:
I
The brake wear warning so Id means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear the brake wear warning sound, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Free movement of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear,
and evenly torque
wheel nuts
in the proper sequence to GM specifications.
Brake linings should always be replaced
as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

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 Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery,
we recommend a Delco Freedom@
battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more,
tLke off the black, negative (-) cable from the battery.
This will help keep your be++ary from running down.
J II’
Batteries have acid that can burn you and gas
that can explode.
You can be badly hurt if you
aren’t careful. See “Jump Starting’’ in the Index
for tips on working around a battery without getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature” in the Index.

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire or tire chain clearance to
the body and chassis.
See “Changing
a Flat Tire” in the Index .for more
information. Used
Replacement Wheels
Putting
a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or
how many miles it’s been driven. It could fail
suddenly and cause an accident.
If you have to
replace a wheel, use a new
GM original
equipment wheel.
