MAINTAINING YOUR VEHICLE 603 • 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 thermostat. Other designs may result in unsatisfactory cooling performance, poor gas mileage, and increased emissions. Brake System In order to assure brake system performance, all brake system components should be periodically inspected. Refer to the "Maintenance Schedule" 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 The fluid level of the master cylinder should be checked when performing under the hood service, or immediately if the brake system warning lamp indicates system failure. The brake master cylinder has a plastic reservoir. On the outboard side of the reservoir, there is a "MAX" dot and a "MIN" dot. The fluid level must be kept within these two dots. Do not add fluid above the MAX mark, because leakage may occur at the cap. 7
