MAINTAINING YOUR VEHICLE 439 Emission-Related Components Positive Crankcase (PCV) Valve Proper operation of the crankcase ventilation system requires that the PCV valve be free of sticking or plugging from deposits. Deposits can accumulate in the PCV valve and passages with increasing mileage. Have the PCV valve, hoses, and passages checked for proper operation at the intervals specified. If the valve is plugged or sticking, replace with a new valve- do not attempt to clean the old PCV valve! Check the ventilation hoses for indications of damage, weepage or plugging with deposits. Replace if necessary. Maintenance Free Battery The top of the maintenance free battery is permanently sealed. You will never have to add water, nor is periodic maintenance required. WARNING! Battery fluid is a corrosive acid solution and can burn or even blind you. Don't allow battery fluid to contact your eyes, skin or clothing. Don't lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area immediately with large amounts of water. Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Don't use a booster battery or any other booster source with an output greater than 12 volts. Don't allow cable clamps to touch each other. Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling. 7
