Maintenance requirements

To ensure safe and economical driving, day-to-day care and regular maintenance are essential. It is the owner’s responsibility to perform regular checks. Toyota recommends the following maintenance:

General maintenance

General maintenance should be performed on a daily basis. This can be done by yourself or by a toyota dealer.

Scheduled maintenance

Scheduled maintenance should be performed at specified intervals according to the maintenance schedule.

For details about maintenance items and schedules, refer to the “scheduled maintenance guide” or “owner’s manual supplement”.

Do-it-yourself maintenance

You can perform some maintenance procedures by yourself.

Please be aware that do-it-yourself maintenance may affect warranty coverage.

The use of toyota repair manuals is recommended.

For details about warranty coverage, refer to the separate “owner’s warranty information booklet” or “owner’s manual supplement”.

Repair and replacement

It is recommended that genuine toyota parts be used for repairs to ensure performance of each system. If non-toyota parts are used in replacement or if a repair shop other than a toyota dealer performs repairs, confirm the warranty coverage.

Emission inspection and maintenance (i/m) programs

Some states have vehicle emission inspection programs which include obd (on board diagnostics) checks. The obd system monitors the operation of the emission control system.

If the malfunction indicator lamp comes on

The obd system determines that a problem exists somewhere in the emission control system. Your vehicle may not pass the i/m test and may need to be repaired. Contact your toyota dealer to service the vehicle.

Your vehicle may not pass the i/m test in the following situations:

• When the battery is disconnected or discharged readiness codes that are set during ordinary driving are erased.

  Also, depending on your driving habits, the readiness codes may not be completely set.

•  When the fuel tank cap is loose the malfunction indicator lamp comes on indicating a temporary malfunction and your vehicle may not pass the i/m test.

When the malfunction indicator lamp still remains on after several driving trips

The error code in the obd system will not be cleared unless the vehicle is driven 40 or more times.

If your vehicle does not pass the i/m test

Contact your toyota dealer to prepare the vehicle for re-testing.
