■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicle’s location and attempts to
speak with the vehicle occupants to assess the level of emergency.
If the occupants are unable to communicate, the agent automati-
cally treats the call as an emergency, contacts the nearest emer-
gency services provider to describe the situation, and requests that
assistance be sent to the location.

■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
Vehicles without a smart key system: Turn the engine switch to the “LOCK”
position with the trip meter A reading shown.
Vehicles with a smart key system: Turn the engine switch off with the trip
meter A reading shown.
Vehicles without a smart key system: While pressing the trip meter reset
button ( P. 95), turn the engine switch to the “ON” position (do not start the
engine, reset mode will be canceled).
Vehicles with a smart key system: While pressing the trip meter reset but-
ton ( P. 95), turn the engine switch to the IGNITION ON mode (do not start
the engine, 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 engine is running, switch the multi-information display to the “Set-
tings” screen. ( P. 94)
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 coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.
