If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what
to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip
the steering wheel firmly.
Steer to maintain lane position, then gently brake
to a
stop well
out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get
the vehicle under control by
steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but
you can still steer. Gently
brake
to a stop, well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change
a flat tire safely.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule
to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the
Index.
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:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
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.
To check the fluid level
0 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).

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution
to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
3/4 full
when it’s very cold. This allows for
expansion, which could damage the tank if
it is completely full.
Don’t use radiator antifreeze in your
windshield washer. It can damage your washer system and paint.
Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is filled with
DOT-3 brake fluid.
There are only two reasons
why the brake fluid level in
your master cylinder 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
6-23
ProCarManuals.com
Page 232 of 340

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.
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 ll@ (GM Part No.
1052535). Use new brake fluid from a sealed container
only, and always clean the brake fluid reservoir cap
before removing it.
NOTICE:

Don’t let someone put in the wrong kind of
fluid. 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.
Brake fluid can damage paint,
so 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),
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.
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 make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate
or heavier stop, then your brakes might not adjust
correctly.
If you drive in that way, then -- very
carefully
-- make a few moderate brake stops about
every
1,000 miles (1 600 km), so your brakes will adjust
properly.

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, take off the black, negative
(-) cable from the
battery. This
will help keep your battery from running
down.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.

Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose,
the wheel,
wheel bolts, and wheel nuts should be replaced. If
the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
Buick dealer
if any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted
the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have
the
right wheel, wheel bolts, and wheel nuts for your Buick
model. 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.
