Toyota Sienna 2010-2025 Owners Manual: Calibrating the compass

The direction display deviates from the true direction determined by the earth’s magnetic field. The amount of deviation varies according to the geographic position of the vehicle.

If you cross over a map boundary shown in illustration, the compass will deviate.

To obtain higher precision or perfect calibration, refer to the following.

Deviation calibration

1. Stop the vehicle where it is safe to drive in a circle.
2. Press and hold the switch.

   A number (1 to 15) appears on the compass display.

3. Referring to the map above, press the switch to select the number of the zone you are in.

   If the direction is displayed several seconds after adjustment, the calibration is complete.

Circling calibration

When “C” appears on the display, drive the vehicle at 5 mph (8 km/h) or less in a circle until a direction is displayed.

If there is not enough space to drive in a circle, drive around the block until the direction is displayed.

Conditions unfavorable to correct operation

The compass may not show the correct direction in the following conditions:

• The vehicle is stopped immediately after turning.
• The vehicle is on an inclined surface.
• The vehicle is in a place where the earth’s magnetic field is subject to interference by artificial magnetic fields (underground car park/parking lot, under a steel tower, between buildings, roof car park/parking lot, near an intersection, near a large vehicle, etc.).
• The vehicle has become magnetized.

  (There is a magnet or metal object near the inside rear view mirror.)

• The battery has been disconnected.
• A door is open.
