370 MAINTAINING YOUR VEHICLE Check ventilation hose for indication of damage or plugging deposits. Replace if necessary. Fuel Filter A plugged fuel filter can cause hard starting or limit the speed at which a vehicle can be driven. Should an excessive amount of dirt accumulate in the fuel tank, frequent filter replacement may be necessary. The fuel filters are located inside the fuel tank. See your dealer for service. Air Cleaner Element (Filter) Under normal driving conditions, replace the filter at the intervals shown on Schedule "A". If, however, you drive the vehicle frequently under dusty or severe conditions, the filter element should be inspected periodically and replaced if necessary at the intervals shown on Schedule "B". NOTE: For vehicles with a Turbo engine, a small amount of oil accumulation in the air cleaner box is normal. The amount will depend on driving style. The air cleaner box should be cleaned out and a new make-upair filter element should be installed during the normal air filter maintenance procedure. WARNING! The air cleaner can provide a measure of protection in the case of engine backfire. Do not remove the air cleaner unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air cleaner removed. Failure to do so can result in serious personal injury.
