Maintenance and care

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 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 procedures described below:
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer. ( P. 170)
Turn the “ENGINE START STOP” switch or the engine switch OFF.
Vehicles with smart key system: While pressing the trip meter reset
button, turn the “ENGINE START STOP” switch to IGNITION ON
mode. Continue to press and hold the button until the trip meter dis-
plays 000000.
Vehicles without smart key system: While pressing the trip meter
reset button, turn the engine switch to the “ON” position. Continue
to press and hold the button until the trip meter displays 000000.
■ 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.
