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.). 13C011 13C012 D During calibration, do not operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration. CALIBRATING THE COMPASS (circling calibration) "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. Drive the vehicle slowly (at 8km/h (5mph) 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. If calibration cannot be performed because of the magnetized vehicle, etc., take your vehicle to Toyota dealer. 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. 104
