SERVICING AND MAINTENANCE 419
(Continued)
• 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 oper-
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat-
isfactory 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 “Maintenance Plan” in this section for the proper
maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
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. Brake fluid level should be checked
when pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
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.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information. 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 identified on the original factory
installed hydraulic master cylinder reservoir.
