CHASSIS To check the fluid level, simply look at the see-through reservoir. The level should be between the "MAX" and "MIN" lines on the tank. It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high. If the reservoir needs frequent refilling, it may indicate a serious mechanical problem. If the level is low, add FMVSS No.116 DOT 3 or SAE J1703 brake fluid to the brake reservoir. Refilling brake fluid: 1. Turn the ignition switch off. 2. Depress the brake pedal more than 40 times. 3. Remove the reservoir cap by hand. Add brake fluid up to the "MAX" line. If you do not follow the procedure above, the reservoir may overflow. Use only newly opened brake fluid. Once opened, brake fluid absorbs moisture from the air, and excess moisture can cause a dangerous loss of braking efficiency. 421
