Calibrating the compass
*
The earth is divided into 15 magnetic zones. The
compass should be calibrated if the car is
moved between several magnetic zones.
Proceed as follows to perform calibration:
1. Stop the car in a large open area free from
steel structures and high-voltage power lines.
2. Start the car and switch off all electrical
equipment (air conditioning, wipers, etc.) and
ensure that all doors are closed.
NOTE
Calibration may fail or not start at all if electri-
cal equipment is not switched off.
3. Hold the button on the underside of the rear-
view mirror depressed (use a paper clip or
similar) for approx. 3 seconds. The number of
the current magnetic zone is shown.
Magnetic zones.
4. Press the button repeatedly until the
required magnetic zone ( 1–15 ) is shown.
See the map of magnetic zones for the com-
pass.
5. Wait until the display returns to showing the
character C , or hold the button on the under-
side of the rearview mirror depressed for
approx. 6 seconds until the character
C is
shown.
6. Drive slowly in a circle at a speed of no more
than 10 km/h (6 mph) until a compass direc-
tion is shown in the display, indicating that
calibration is complete. Then drive a further 2
circles to fine-tune calibration.
7. Cars with heated windscreen
*
: If the char-
acter C is shown in the display when the
heated windscreen is activated, perform the
calibration in accordance with point 6 above
with the heated windscreen activated.
8. Repeat the above procedure as necessary.
