To ensure safe and economical driving, day-to-day care and regular maintenance is essential. It is the owner’s responsibility to perform regular checks. Toyota recommends the following maintenance.
■ General maintenance
Should be performed on a daily basis. This can be done by yourself or by a Toyota dealer.
■ 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 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”, “Owner’s Manual Supplement”.
■Repair and replacement
It is recommended that genuine Toyota parts be used for repair to ensure performance of each system. If non-Toyota parts are used in replacement or if a repair shop other than Toyota dealer performs repairs, confirm the warranty coverage.
■Reset the maintenance data (U.S.A. only)
After the required maintenance is performed according to the maintenance schedule, please reset the maintenance data.
To reset the data, follow the procedures described below:
Switch the display to the trip
meter A when the engine is running.
Turn the engine switch to the LOCK
position.
While pressing the ODO/TRIP button
(→P. 155), turn the engine switch to the ON position. Continue to press and hold
the button until the odometer displays 000000.
If the system fails to reset, the light will continue flashing.
■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.
CAUTION
■Warning in handling of battery
●Engine exhaust, some of its constituents, and a wide variety of automobile components contain or emit chemicals known to the State of California to cause cancer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by component wear contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Avoid exposure and wash any affected area immediately.
●Battery posts, terminals and related accessories contain lead and lead compounds which are known to cause brain damage. Wash your hands after handling.
