Toyota Corolla Repair Manual: Pre–check
1. Selecting compass display mode
- the compass switch allows you to select the display or non–display
mode of the compass.
2. Setting 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 according to the
area where the vehicle is used, it is necessary for each user to set the
zone (refer to ”compass zone
map”). The zone setting can be changed using the comp switch of the inner
mirror.
3. Performing 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 magnetized:
- a compass could be magnetized during shipping by vessels or
freight cars. Before delivery, therefore,
make sure to perform calibration and ensure that calibration is done
properly. If it cannot be done (cannot
be complete in spite of driving around several times), it may be caused by
magnetization. Demagnetize
the vehicle using a demagnetizer and perform calibration again.
5. Setting compass

6. Zone setting mode
- pressing the comp switch for 3 seconds, in the normal mode, will
activate the zone setting mode.
A number (1 – 15) is displayed on the compass display.
Hint
:
in the initial state, ”8” is displayed.
- the displayed number increases +1 every time the comp 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 ”c”.
7. Calibration setting mode
- pressing the comp switch for 6 seconds, in the normal mode, will
also activate this 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.
Hint
:
once calibration is complete, 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 ”c”.
