Toyota Sienna Service Manual: Calibration
1. SELECT COMPASS DISPLAY MODE
- The MODE switch allows you to select the Display
or Non-display mode of the compass.
HINT:
In compass display mode, the display indicates
outside temperature/average fuel consumption/
instantaneous fuel consumption/distance to empty
with compass.
2. SET ZONE
- Deviation between the "magnetic north" and "actual
north" differs depending on the location. Therefore,
adjustment of the magnetism is required. Since the
magnetic condition differs depending on the area
where the vehicle is used, it is necessary for each
user to set the zone (Refer to Zone Setting Map).
The zone setting can be changed using the MODE
switch of the accessory meter assembly.
3. PERFORM CALIBRATION
- Because each vehicle has its own magnetic field,
calibration should be performed for each vehicle.
This compass function is used when storing the
record of the vehicle's magnetic field.
4. WHEN COMPASS IS MAGNETIZED
- A compass could be magnetized during shipping by
vessels or freight cars. Therefore, make sure to
perform calibration and ensure that calibration is
performed properly before delivery. If it cannot be
done (cannot be completed in spite of driving
around several times), it may be caused by
magnetization. Demagnetize the vehicle using a
demagnetizer and perform calibration again.
5. SET COMPASS

6. ZONE SETTING MODE (PROCEDURE "A")
- Pressing the E/M and MODE switches
simultaneously for 5 seconds in the normal mode
will activate the zone setting mode. A number (1 to
15) is displayed on the compass display.
NOTICE:
In the initial state, "VAR" is displayed.
- The displayed number increases by 1 every time the
E/M switch is pressed. Referring to the map, check
the number for the area where the vehicle will be
used and set the zone number.
- Leave it untouched for several seconds after setting
and check that the compass display shows an
azimuthal direction (N, NE, E, SE, S, SW, W or NW)
or "CAL".
7. CALIBRATION SETTING MODE (PROCEDURE "B")
- Pressing the E/M and MODE switches
simultaneously for 10 seconds in the normal mode
will activate the calibration setting mode.
- Drive the vehicle at a slow speed of 8 km/h (5 mph)
or less in the circular direction.
- Driving around the circle 1 to 3 times will display the
azimuthal direction on the display, completing the
calibration.
NOTICE:
After the calibration is completed, it is not
necessary to perform the above procedures
unless the magnetic field strength is drastically
changed. If this happens, the azimuthal display
will be changed to "CAL".
