MAINTAINING YOUR VEHICLE 277 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. Maintenance-Free Battery You will never have to add water, nor is periodic maintenance required. CAUTION! When servicing the battery, always reinstall the battery thermowrap. The thermowrap provides battery heat protection and will extend overall battery life. Failure to reinstall the thermowrap can result in evaporative loss of the battery fluid. 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. 7
