The vehicle is on an inclined surface.●
The vehicle is in a place where the earth’s
magnetic field is subj ect to interference
by artificial magnetic fields (under-
ground 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.

Deviation
The direction display deviates from the
true direction determined by the
earth’s magnetic field. The amount of
deviation varies depending on the geo-
graphic position of the vehicle.
If you cross over one of the map boundar- ies shown in illustration, the compass will
deviate.
To obtain higher precision or perfect cali-
bration, refer to “D eviation calibration”.

1 Stop the vehicle.WARNING■
While driving the vehicle
Do not adjust the display. Adjust the dis-
play only when the vehicle is stopped. NOTICE■
To avoid compass malfunctions
Do not place magnets or any metal
objects near the inside rear view mirror.
Doing this may cause the compass sen-
sor to malfunction. ■
To ensure normal operation of the
compass ●
Do not perform a circling calibration of
the compass in a place where the
earth’s magnetic field is subject to
interference by artificial magnetic
