CALIBRATING THE COMPASS (circling
calibration)
Sometimes the direction display on the
compass may not change after a turn. To
rectify this, stop the vehicle and push and
hold the switch until "C" appears on the
display.
If "C" appears on the display because of
a drastic change in the magnetic field,
perform circling calibration.
Drive the vehicle in a circle at 8 km/h (5
mph) or less. If there is not enough space
to drive in a circle, drive around the
block.
After driving 1 to 3 circles in the above
method, calibration is completed when the
direction is shown on the display.
If calibration cannot be performed because
of the magnetized vehicle etc., take your
vehicle to Toyota dealer.
