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, see 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.

Resetting the message indicating maintenance is required (U.S.A. only)

After the required maintenance is preformed according to the maintenance schedule, please reset the message.

To reset the message, follow the procedures described below:

Using the odometer and trip meter display

Turn the engine switch to the “LOCK” position (vehicles without a smart key system) or off (vehicles with a smart key system) with the trip meter A reading shown.
While pressing the odometer/trip meter display change button , turn the engine switch to the “ON” position (vehicles without a smart key system) or IGNITION ON mode (vehicles with a smart key system) (do not start the engine because otherwise the reset mode will be canceled).

Using the multi-information display (vehicles with color display)

While the engine is running, switch the multi-information display to the “Settings” screen.
Select “Maintenance Reset” on the “Settings” screen.
Select “Yes” on the “Maintenance Reset” screen.

“Maintenance Reset Complete” will be displayed on the multi-information display when the reset procedure has been completed.

Allow inspection and repairs to be performed by a Toyota dealer

Toyota technicians are well-trained specialists and are kept up to date with the latest service information. They are well informed about the operations of all systems on your vehicle.
Keep a copy of the repair order. It proves that the maintenance that has been performed is under warranty coverage. If any problem should arise while your vehicle is under warranty, your Toyota dealer will promptly take care of it.
