Introduction
Some 2011 model Tundra vehicles are equipped with a compass in the rear view mirror. In order for the compass to correctly indicate the direction that the vehicle is heading it must be calibrated prior to vehicle delivery. Use the following procedure to perform initial calibration during Pre-Delivery Service (PDS).

Compass Calibration Procedure
1. Cycle the ignition switch to the "IG-ON" position.
2. Push and hold the "N" switch until the zone number appears on the compass display.
^ Pushing the "N" switch turns the compass
^ display ON or OFF.
3. Push the "N" switch to select the number of the zone where the vehicle is located. See the map in Figure 3 for zone reference.
4. Once the correct zone is selected start the engine and push and hold the "N" switch until "CAL" appears on the display (approximately 6 seconds).
5. Drive the vehicle slowly at 5mph (8 km/h) or less in a circle until the direction is displayed. If there is NOT enough space to drive in a circle, turn the vehicle around as shown, doing two three-point turns in succession.
Once the direction is displayed, the calibration is complete.
^ Do NOT perform calibration of the compass in a place where the Earth's magnetic field is subject to interference (underground parking, under a steel tower, between buildings, roof parking, near a railroad crossing, near a large vehicle, etc.)
^ During calibration, do NOT operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration.
