'05 TUNDRA_U (L/O 0504) CALIBRATING THE COMPASS (deviation calibration) The direction display on the compass deviates from the true direction determined by the earth's magnetic field. The angle of deviation varies according to the geographic position of the vehicle. To adjust for this deviation; 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.) 2. Push and hold both the "MODE" and "E/M" buttons simultaneously for 5 seconds until the "VAR" indication appears on the compass display. 3. Push the "E/M" button several times until the desired zone number appears on the compass display. If the button is not pushed for 10 seconds, the display returns to the compass/ outside temperature mode and the number that is last set is memorized. To select the zone where the vehicle is currently located, refer to the following map. 315 2005 TUNDRA from Apr. '05 Prod. (OM34440U)
