IS 250C V6-2.5L (4GR-FSE) (2011)
Compass: Testing and Inspection
MIRROR (INT): INNER REAR VIEW MIRROR: CALIBRATION
1. SELECT COMPASS DISPLAY MODE
(a) The AUTO switch allows you to select whether or not the compass is displayed.
2. SET ZONE
(a) The compass indicates the direction that the vehicle is heading by detecting the direction and strength of the earth's magnetic field (magnetic
north). However, there is a difference between magnetic north and actual north that depends on the location of the vehicle. To compensate for
this difference, it is necessary to set the zone in which the vehicle will be used (Refer to Compass Zone Map). The zone setting can be changed
using the AUTO switch of the inner mirror.
3. PERFORM CALIBRATION
(a) Because each vehicle has its own magnetic field, calibration should be performed. The calibration function is used to compensate for the
residual magnetism of the vehicle.
4. WHEN COMPASS IS MAGNETIZED
(a) The compass or vehicle may become magnetized while the vehicle is being shipped. As a result, it is necessary to perform calibration for the
compass before the vehicle is delivered to the customer. If calibration cannot be performed successfully (calibration cannot be completed in
spite of driving around several times), it may be caused by excessive magnetization of the vehicle. Demagnetize the vehicle using a
demagnetizer and perform calibration again.
5. SET COMPASS
HINT
It returns to a normal mode when the AUTO switch is pressed for 12 seconds or more.
6. ZONE SETTING MODE
(a) When the compass is in normal mode, pressing the AUTO switch for 9 seconds will activate zone setting mode. A number from 1 to 15 will be
displayed on the compass display.
