For obtaining additional precision or for complete calibrating, see the following "CALIBRATING THE COMPASS" on page 64. COMPASS SENSOR NOTICE Do not put magnets or a metal object near the audio system. Doing this may cause malfunction of the compass sensor. CALIBRATING THE COMPASS The direction display on the compass deviates from the true direction determined by the earth's magnetic field. The amount of deviation varies according to the geographic position of the vehicle. If you cross over the area divided as shown in the illustration, the compass will deviate. If it is necessary to calibrate the compass (deviation calibration), take your vehicle to your Lexus dealer. Even if you do not cross over, the compass may sometimes deviate. If this happens, perform "DRIVE IN CIRCLES" calibration as shown on the next page. 13L072 "Compass sensor The compass sensor is located behind the audio system.
