Checking Brake Fluid { CAUTION: If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. See "Checking Brake Fluid" in this section. When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 3-39. Refer to the Maintenance Schedule to determine when to check the brake fluid. See Scheduled Maintenance on page 7-4. Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 6-14. The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark. 6-37
