CHASSIS 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 cover 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. CAUTION Take care when filling the reservoir because brake fluid can harm your eyes and damage painted surfaces. If fluid gets in your eyes, flush your eyes with clean water. NOTICE For vehicles with traction control system only: Idle the engine while pouring brake fluid into the reservoir. 268
