STEERING WHEEL AND MIRRORS Perform circling calibration just after you have purchased your Lexus. And then always perform circling calibration after the battery has been removed, replaced or disconnected. 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 (moonroof, power windows, etc.) as they may interfere with the calibration. VANITY 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. To use the vanity mirror, swing the sun visor down and open the cover. The vanity light comes on when you open the cover. To adjust the brightness of the vanity light, slide the knob. 263
