■Circling calibration
When “C” appears on the dis-
play, drive the vehicle at 5 mph
(8 km/h) or less in a circle until
a direction is displayed.
If there is not enough space to
drive in a circle, drive around the
block until the direction is dis-
played.
■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
● The vehicle is on an inclined surface.
● The vehicle is in a place where the earth’s magnetic field is subject to inter-
ference by artificial magnetic fiel ds (underground car park/parking lot, under
a steel tower, between buildings, roof car park/parking lot, near an intersec-
tion, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
● The battery has been disconnected.
● A door is open.
WARNING
■ While driving the vehicle
Do not adjust the display. Adjust the display only when the vehicle is
stopped.
■ When doing the circling calibration
Secure a wide space, and watch out for people and vehicles in the vicinity.
Do not violate any local traffic rules while performing circling calibration.

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.
■ Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is preformed according to the maintenance
schedule, please reset the message.
To reset the message, follow the procedures described below:
Using the odometer and trip meter display
Turn the engine switch to the “LOCK” position (vehicles without a smart key
system) or off (vehicles with a smart key system) with the trip meter A read-
ing shown. ( P. 88)
While pressing the odometer/trip meter display change button ( P. 87),
turn the engine switch to the “ON” position (vehicles without a smart key
system) or IGNITION ON mode (vehicles with a smart key system) (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”
and the multi-information display indicates that the reset is complete.
Using the multi-information display (vehicles with color display)
While the engine is running, switch the multi-information display to the
“Settings” screen. ( P. 624)
Select “Maintenance Reset” on the “Settings” screen.
Select “Yes” on the “Maintenance Reset” screen.
“Maintenance Reset Complete” will be displayed on the multi-information dis-
play 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.
