recovery bottle does not drop when the
engine cools, the cooling system should be
pressure-tested for leaks.
• Maintain the engine coolant (antifreeze) con-
centration at 50% HOAT engine coolant (an-
tifreeze) (minimum) and distilled water for
proper corrosion protection of your engine
which contains aluminum components.
• Make sure that the radiator and coolant
recovery bottle hoses are not kinked or ob-
structed.
• 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 nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory cooling performance, poor gas mileage,
and increased emissions.

Brake System

In order to assure brake system performance,
all brake system components should be in-
254
spected periodically. Refer to the "Maintenance
Schedule" for the proper maintenance inter-
vals.
WARNING!
Riding the brakes can lead to brake failure
and possibly an accident. 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.
Power Disc Brakes
Disc brakes do not require adjustment; how-
ever, several hard stops during the break-in
period are recommended to seat the linings
and wear off any foreign material.
Brake Master Cylinder
The fluid level in the master cylinders should be
checked whenever the vehicle is serviced. If
necessary, add fluid to bring level to the full
level mark on the side of the reservoir of the
brake master cylinder. With disc brakes, fluid
level can be expected to fall as the brake pads
wear. If the brake fluid level is abnormally low,
check system for leaks.
Refer to "Fluids, Lubricants, and Genuine
Parts" in "Maintaining Your Vehicle" for the
correct fluid type.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to "Fluids, Lubricants,
and Genuine Parts" in "Maintaining Your
Vehicle" for the correct fluid type. Using the
wrong type of brake fluid can severely
damage your brake system and/or impair
its performance. The proper type of brake
fluid for your vehicle is also labeled on the
original factory installed hydraulic master
cylinder reservoir.
