Interior features Calibrating the compass
The direction display deviates from the true direction determined by the
earth’s magnetic field. The amount of deviation varies depending on the
geographic position of the vehicle. If you cross over one of the map boundaries shown in illustration, the com-
pass will deviate.
To obtain higher precision or perfect calibration, refer to “Deviation calibra-
tion”.
■ Deviation calibration
Stop the vehicle.
Press and hold .
A number (1 to 15) appears on the
compass display.
The location the compass is dis-
played differs according to the type
of inner rear view mirror.STEP 1

Referring to the map above, pr ess to select the number of
the zone you are in. If the direction is displayed for several seconds after adjustment, the
calibration is complete.
■ Circling calibration
If “C” appears on the display, 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 a direction is displayed.STEP 3

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 interfer-
ence by artificial magnetic fields (underground car park/parking lot, under a
steel tower, between buildings, roof car pa rk/parking lot, near an intersection,
