232 SERVICING AND MAINTENANCE
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the ther-
mostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
Do not overfill the coolant expansion bottle.

Check the coolant freeze point in the radiator

and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle
must also be protected against freezing.
If frequent engine coolant (antifreeze) addi-

tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen-

tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo-
nents.
Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your

vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or

Winter operation. If replacement is ever
necessary, install ONLY the correct type ther-
mostat. Other designs may result in unsatis-
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.

Brake System

In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the "Service and
Warranty Handbook (Auto Biography)" for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the "FULL" mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only brake fluid that has been recom-
mended by the manufacturer, and has been
kept in a tightly closed container to avoid
contamination from foreign matter or moisture.
Refer to "Fluids And Lubricants" in "Technical
Specifications" for further information.
