Inner Rear View Mirror ASSY: Pre-Check

1. The comp switch allows you to select a Display or Non-display mode of the compass.

1. Deviation between the "magnetic north" and "actual north" differs depending on the location. Therefore, adjustment of the magnetism is required. Since the magnetic condition differs depending on the area where the vehicle is used, it is necessary for each user to set the zone. (Refer to "Compass Zone Map"). The zone setting can be changed using the comp switch of the inner mirror.

1. Since each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass function is used when storing the record of the magnetic field of the vehicle.

1. A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore, make sure to perform calibration and ensure that calibration is done properly. If it cannot be done (cannot be complete in spite of driving around several times), it may be caused by magnetization. Demagnetize the vehicle using a demagnetizer and perform calibration again.

1. Press the comp switch for 3 seconds. In the normal mode, the zone setting mode will activate. A number (1-15) is displayed on the compass display.

   HINT:

   In the initial status, "8" is displayed.

2. The displayed number increases +1 every time the comp switch is pressed. Referring to the map, check the number for the area where the vehicle will be used and set the zone number.
3. Leave it untouched for several seconds after setting and check that the compass display shows an azimuthal direction (N, NE, E, SE, S, SW, W or NW) or "C".

1. Press the comp switch for 6 seconds. in the normal mode, this mode will also activate.
2. Drive the vehicle at a slow speed of 8 km/h (5 MPH) or less in the circular direction.
3. Driving around the circle 1 to 3 times will display the azimuthal direction on the display, completing the calibration.

HINT:

Once calibration is completed, it is not necessary to perform the above procedures unless the magnetic field strength is drastically changed. If this happens, the azimuthal display will be changed to "C".
