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.
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.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F (82°C
to 93°C).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above
50°F
(10°C). If it's colder than 50°F (IOOC), you may have
to drive longer.
Checking the Fluid Level

Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift lever
in PARK (P).
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).
Let the engine run at idle for three to five minutes.

Brakes
Brake Fluid
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.
’ A CAUTION:
F-
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 1 l@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean
the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
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.
1
NOTICE:
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.
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 vehicle 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 firmy).
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.
Properly torqued wheel nuts are necessary
to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to
GM specifications.
The brake wear warning sound means that soon
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 Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Brake Pedal navel
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.
Your vehicle was designed and tested with top-quality
GM brake parts. 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 approved 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 an ACDelco Freedom@ battery.
You never have to add water to one of these. When it’s
time for a new battery, we recommend an ACDelco
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, remove
the black, negative (-) cable from
the battery. This will help keep your battery from
running down.
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.

Used Replacement Wheels
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling of your vehicle, make your tires lose air
and make you lose control. You could have
a
collision in which you or others could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
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.
Putting a used wheel on your vehicle is
dangerous.
You can’t know how it’s been used or
how
far 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.
Tire Chains
NOTICE:
If your vehicle has P225/60R16 size tires, don’t
use tire chains. They can damage your vehicle
because there’s not enough clearance.
