n 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.
n Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
l The vehicle is stopped immediately after turning.
l The vehicle is on an inclined surface.
l 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.).
l The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
l The battery has been disconnected.
l A door is open.
CAUTION
n While driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle
is stopped.
n 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.
