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, rear window defroster etc.) should be switched
off, doors and liftgate closed. Do not open or close the
roof. An open 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 and afterwards press MODE key,
“CAL–” appears in the display.4. Press and hold RESET key for a minimum of
2 seconds, to access the calibration mode.
The display shows “CAL”.
5. Without interruption drive two full circles at a speed
between 3 mph (5 km / h) and 7 mph (10 km / h).
The message “CAL” goes out after a short time.
6. The calibration of the compass is now complete.
Note:
If “CAL” remains in the display, calibration was not
successfully completed. To recalibrate, remove key from
the steering lock. Insert key, start the vehicle and start
the calibration procedure.
We recommend that you have the compass calibrated at
a Mercedes-Benz Light Truck Center.
