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.

Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of th e 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:
●When the battery is disconnected or discharged
Readiness codes that are se t 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 as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off 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.
