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.

your master cylinder might go down. The first is that the Light,’ in the Index,
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

100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on
specified government test surfaces of asphalt and
concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade
C corresponds to a level of performance
whicrall passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
I
excessive loading, either separately or in combination, !
can cause heat buildup and possible tire failure.
Those grade
b are molded on the sidewalls of passenger
car tires.
While the tires available as standard or optional
equipment on General Motors vehicles may vary with
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use
on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements in addition to these grades.

INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment. You may need to have
your brakes inspected more often if
your driving habits or conditions
result in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also, if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays on or
comes
-on, something may be wrong
with the anti-lock brake system. See “Anti-Lock Brake System Warning
Light” in the Index.
