Circling calibration
When 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 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
interference by artificial magnetic fields (underground car park/parking
lot, under a steel tower, between buildings, roof car park/parking lot, near
an intersection, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
● The 12-volt battery has been disconnected.
● A door is open.
CAUTION
■While driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle
is stopped.
■ When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the
neighborhood. Do not violate any local traffic rules while performing circling
calibration.
