03 07.09 STEERING WHEEL AND MIRRORS CAUTION Do not adjust the display while the vehicle is moving. Be sure to adjust the display only when the vehicle is stopped. CALIBRATING THE COMPASS (circling calibration) SV16079 SV16139 Drive the vehicle slowly (at 8 km/h (5 mph) or lower) in a circle until the direction is displayed. If there is not enough space to drive in a circle, drive around the block until the direction is displayed. After driving in 1 to 3 circles in the above method, calibration is complete with the direction shown on the display. "C" appears on the display in case the circling calibration is required due to a drastic change in the magnetic field. To rectify this, follow the calibration procedure below. If calibration cannot be performed because of the magnetized vehicle, etc., take your vehicle to Lexus dealer. D Do not perform circling calibration of the compass in a place where the earth's magnetic field is subject to interference by artificial magnetic fields (underground parking, under a steel tower, between buildings, roof parking, near a crossing, near a large vehicle, etc.). D During calibration, do not operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration. 186
