With the engine switch on, the electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is high. n Safety glasses Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in the eyes. 4 NOTICE Maintenance and care n If you remove the air cleaner Driving with the air cleaner removed may cause excessive engine wear due to dirt in the air. Also a backfire could cause a fire in the engine compartment. n If the brake fluid level is low or high 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 problem. 235
