According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect. The following simple and inexpensive preventive checks will greatly extend the life of the vehicle, ensure safer operation and even benefit the environment.
 

	Always consult your owner’s manual, but a good rule of thumb is to have the oil filter changed regularly, every 3,000 to 4,000 miles.
	Have all fluids checked, including brake, power steering, transmission/transaxle, windshield washer solvent and antifreeze. These fluids play a large role in the safety and performance of the vehicle.
	Check tire inflation. Under-inflated tires can result in a loss of fuel efficiency. This is the least expensive form of preventive and safety maintenance. Tires should be checked once a month.
	Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
	Have the chassis lubricated frequently. This step extends the life of the moving components of the vehicle's suspension system.
	Check battery cables and posts for corrosion and clean them as needed. The battery fluid should also be checked and filled if it is low, except in the case of maintenance-free batteries.
	Have the lighting system checked frequently, including headlights, turn signals, and brake and tail lights.
	Check windshield washer blades for cracks, tears and windshield contact. Replace them approximately once a year or sooner if streaking begins.
	Inspect engine belts regularly. Worn belts will affect the engine performance. Look for cracks and missing sections or segments.
	Have the air filtration system checked frequently. The air filter should be checked approximately every other oil change for clogging or damage. This system ensures that the vehicle is performing at its peak condition.
	A dirty cabin air filter can also impair airflow in the HVAC system, possibly causing interior heating and cooling problems. Over time, the heater and air conditioner may also become damaged by corrosion. If you get headaches, allergic reactions or breathing problems riding in your car, it's probably time to change the cabin air filter. Cabin air filters clean the incoming air and remove allergens, and should be replaced every 12,000 to 15,000 miles.

Always consult the vehicle owner's manual for individual service schedules as manufacturer maintenance requirements vary greatly.
