(At this time, the compass display is locked in "N".) CALIBRATING THE COMPASS (circling calibration) Sometimes the direction display on the compass may not change after a turn. In this case, the compass needs to be calibrated. To calibrate the compass manually, do the following; 1. Stop the vehicle in a level place and switch the display to the outside temperature. (To switch to this mode, see "-Outside temperature display" in this Section.) 3. Drive the vehicle in a circle at 8 km/h (5 mph) or less. If there is not enough space to drive in a circle, drive around the block. When the "CAL" indication goes off and the compass returns to the normal mode, calibration is complete. If you want to restart the calibration before it is complete, push both of the "MODE" and "E/M" buttons simultaneously for 10 seconds again. 326 2006 TUNDRA from Oct. '06 Prod. (OM34458U)
