Proper maintenance and tune-up is the key to long and trouble-free vehicle life, and the work can yield its own rewards. Studies have shown that a properly tuned and maintained vehicle can achieve better gas mileage than an out-of-tune vehicle. As a conscientious owner and driver, set aside a Saturday morning, say once a month, to check or replace items which could cause major problems later. Keep your own personal log to jot down which services you performed, how much the parts cost you, the date, and the exact odometer reading at the time. Keep all receipts for such items as engine oil and filters, so that they may be referred to in case of related problems or to determine operating expenses. As a do-it-yourselfer, these receipts are the only proof you have that the required maintenance was performed. In the event of a warranty problem, these receipts will be invaluable.

The literature provided with your vehicle when it was originally delivered includes the factory recommended maintenance schedule. If you no longer have this literature, replacement copies are usually available from the dealer. A maintenance schedule is provided later in this section, in case you do not have the factory literature.

These checks and inspections can be done either by yourself a reputable shop, or the Toyota dealer.

Here are a few of the scheduled maintenance items that need to be checked frequently:


Tire pressure-use a gauge to check the pressure
Tire surfaces and lug nuts-check the tread depth and ensure all the lug nuts are in place
Tire rotation-rotate every 6200 miles (1000 km)
Fluid leaks-check the underneath for leaks of any kind
Doors and the engine hood-check the latches ensuring they are securing properly


Lights-make sure all the lights are in working order
Reminder indicators-ensue all the warning lights and buzzers function properly
Horn-toot the horn to make sure it works when needed
Seats-be aware of any adjuster problems, a moving seat while you're driving is dangerous
Seat belts-are they all working properly
Accelerator pedal-check for smooth operation
Clutch pedal-check for smooth operation and free-play
Brake pedal-check for smooth operation and free-play
Brakes-in a safe location, check for any brake pull


Washer fluid-check the fluid level
Engine coolant level-make sure the level is between the FULL and LOW marks
Battery-if you have a maintenance battery, check the electrolyte levels
Brake and clutch fluid levels-have the levels near the upper line of the reservoirs
Engine oil level-with the engine OFF , check fluid level on the dipstick
Power steering fluid-the level should be between HOT and COLD
Exhaust system-visually check for cracks, holes and loose supports. Be aware of a sudden noise change in the exhaust

Along with these maintenance items, a tune-up is also part of this. A tune-up is not what it used to be years ago where you need to replace the spark plugs every 7500 miles (12,000 km). These days you can replace the plugs on some vehicles every 48,000 miles (77,000 km) or even 100,000 miles (160,900 km).
