STEERING WHEEL AND MIRRORS CAUTION D When doing the circling calibration, be sure to secure a wide space, and watch out for people and vehicles in the neighborhood. Do not violate any local traffic rules while performing circling calibration. D Do not adjust the display while the vehicle is moving. Be sure to adjust the display only when the vehicle is stopped. 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 "CAL" off the display and the direction shown on the display. If calibration cannot be performed because of the vehicle is magnetized, take your vehicle to a 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. G17012 213
