THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71 Defrosters Check operation by selecting the DEFROST mode and place the blower control on high speed. You should be able to feel the air directed against the windshield. See your authorized dealer for service if your defroster is inoperable. Safety Checks You Should Make Outside the Vehicle Tires Examine tires for excessive tread wear or uneven wear patterns. Check for stones, nails, glass, or other objects lodged in the tread. Inspect for tread cuts or sidewall cracks. Check wheel nuts for tightness. Check the tires (including spare) for proper pressure. Lights Have someone observe the operation of all exterior lights while you work the controls. Check turn signal and high beam indicator lights on the instrument panel. Fluid Leaks Check the area under the vehicle after overnight parking for fuel, coolant, oil or other fluid leaks. Also, if gasoline fumes are detected, the cause should be located and corrected immediately. 2
