CHASSIS CHECKING BRAKE FLUID CAUTION Take care when filling the reservoir because brake fluid can harm your hands or eyes. If fluid gets on your hands or in your eyes, flush the affected area with clean water immediately. If you still feel uncomfortable with your hands or eyes, go to the doctor. NOTICE If you spill some of the fluid, be sure to wipe it off to prevent it from damaging the parts or paintwork. 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. So be sure to keep the reservoir filled. 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. Remove and replace the reservoir cap by hand. Add brake fluid up to the "MAX" line. 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. 568
