To calibrate the compass:
If the vehicle was exposed to a significant magnetic
zone, such as high voltage power lines, the compass
may have to be calibrated.
Calibration of the compass should be done in an area
free of steel superstructures and power lines. All
electrical consumers (e.g. exterior lamps, climate
control, etc.) should be switched off, doors and liftgate
closed. Do not open or close the roof. An open door or
liftgate triggers the display “–––”.
1. Start and run the engine.
2. Press MODE key repeatedly until the compass
display appears in the trip computer display.
3. Press RESET key to select the compass zone display.
4. Press RESET repeatedly until the correct zone, as
determined from the zone map (see page 85), is
shown in the display.
5. Press MODE key, “CAL–” appears in the display.
6. Press and hold RESET for a minimum of 2 seconds.7. Without interruption drive two or more full circles
at a speed between 3 mph (5 km / h) and 7 mph
(10 km / h) during which the message “CAL” is
replaced with a compass bearing (e.g. N, SW etc.),
immediately followed by three full circles at the
same speed, with only the rear window defroster
switched on. The defroster can be switched off
again. The calibration of the compass is now
complete.
