The angle of deviation varies according to the geographic position of the vehicle. To adjust this deviation, stop the vehicle, then push and hold the both personal light switches until the zone number appears on the display. Then push the right side or left side personal light switch, referring to the following map to select the number of the zone where the vehicle is. The compass sensor is in the inside rear view mirror. NOTICE Do not put magnets or a metal object on or near the inside rear view mirror of the vehicle.
