Maintenance and care
■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 war-
ranty 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 procedure described below:
Using the trip meter
Turn the power switch off with the trip meter A reading shown.
While pressing the trip meter reset button ( P. 104), turn the power switch
to the ON mode (do not start the engine because otherwise the reset mode
will be canceled).
Continue to press and hold the button until the trip meter displays “000000”.
Using the multi-information display (vehicles with color display)
While the hybrid system operating, switch the multi-information display to
the “Settings” screen. ( P. 103)
Select “Maintenance System” on the “Settings” screen.
Select “Yes” on the “Maintenance System” screen.
“Initialization Completed” 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 cove rage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.

mation display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fans and engine
drive belt.

manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
