A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more
light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@
battery installed
in every new GM vehicle. But if
a battery has filler caps, be sure the right
amount of fluid
is there. If it is low, add water to
take care of that first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with

Engine Overheating
You willi find a coolant temperature gage and the
warning light about a hot engine on your Buick
instrument panel.
If Steam Is Coming From Your Engine:

A CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam
coming from
it. Just turn it off and get everyone
away from the vehicle until
it cools down. Wait
until there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if
it overheats, and get out of the vehicle
until the engine is cool.
If No Steam Is Coming From Your Engine:
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:

Now put all the equipment back securely in the trunk.
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 ti\
re
as soon as you can. Your spare will last longer and be in
good shape in case you need it again.

are made especially for your automatic transaxle.
Damage caused by fluid other than
DEXRONs-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 overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Buick
will:
Give freezing protection down to -34’F (-37 ’ C) .
0 Give boiling protection up to 262 ’ F ( 128 ’ C) .
Protect against rust and corrosion.
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. Use GM Engine Coolant Supplement (sealer) with
any complete coolant change. You can also use a
recycled coolant conforming to “GM Specifications
1825-M” with a complete coolant flush and-refill.
If you
use these, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warnin!
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine coul
get
too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or others could be burned. Use a
50150 mix of
clean water and
a proper antifreeze.

Fuses and Circuit Breakers
The wiring circuits in your car are protected from short
circuits by a combination of fuses, circuit breakers, and
fusible thermal links in the wiring itself.. This greatly
reduces the chance of fires caused by electrical
problems.
Be sure to use the correct fuse if you need to replace
one.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one
of the correct
value. Just pick some feature
of your car that you can
get along without
- like the radio or cigarette lighter -
and use its fuse, if it is of the value you need. Replace it
as soon as you can.
There are two fuse block areas inside your vehicle. One is located on the left side of the console under a carpeted
panel cover. Remove the cover to access the fuses.
