Compact Spare Tire
Although the compact spare was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 kPa). The compact spare is made to go up to 3,000
miles (5000 km), so you can finish your trip and have
your full-size tire repaired or replaced where you want.
Of course, it's best to replace your spare with a full-size
tire as
soon as you can. Your spare will last longer and
be in
good shape in case you need it again.
Your anti-lock brake system warning light may come
on
when you are driving with a compact spare. See
"Anti-Lock Brake System Warning Light"
in the Index.
NOTICE:
' Don't take your compact spare through an
automatic car wash with guide rails. The
compact spare can get caught
on the rails. Tha
can damage the tire and wheel, and maybe other
parts of your vehicle.

Before closing the hood, be sure all the filler caps are on
properly.
Then just pull the hood down and close it firmly.
Engine Oil
If the “LOW OIL” light on the instrument panel comes
on, it means you need to check your engine oil level
right away.
You should check your engine oil level
regularly, the light
is an added reminder. It’s
a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
The dipstick is located near the front and center
of the
engine compartment.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
ProCarManuals.com

If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick. It doesn’t take much fluid, generally less than a
pint. Don’t overfill. We recommend you use only fluid
labeled DEXRONB-IIE, because fluids with that label
are made especially for your automatic transaxle.
Damage caused by fluid other than DEXRONB-IIE is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheat.ing or if you need to add coolant to your
radiator, see “Engine Overheating”
in the Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34OF (-37OC) .
0 Give boiling protection up to 262 OF (128 “C) .
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825-M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change. If you use these, you
don’t need to add anything else.
can be aangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overhe-”
warning. Your engine could catch fire and
yuu or
others could be burned. Use a 50/50 mix of clean
water and a proper antifreeze.

To Add Coolant: If you need more coolant, add the
proper mix at the coolant recovery tank.
A CAUTION:
Turning me raalaror pressure cap when the
--1gine and radiator are hot can allow steam ana
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almos'
never have to add coolant at the radiator. Never

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

DOT-5 silicone brake fluid can damage
your vehicle. Don’t use it.
Don’t let someone put
in the wrong kind 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.
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
