Installing magnetic field sensor

CAUTION:
Safety-related bolts.
- Always replace fastening screws for the belt buckle bracket after customer service and reworking.
- Never make alterations to the micro-encapsulated screws, which have a negative effect on the bond (e.g. using lubricant, loosening bolts and screwing them down again).

3. Calibrate magnetic-field sensor

Calibrating magnetic field sensor

INFORMATION:
- After replacing the magnetic-field sensor, a calibration must be performed.
- In the multi-function display the warning CAL appears.
- To calibrate the compass follow the instructions of the multi-function display.

1. On the instruction DRIVE A FULL CIRCLE, the vehicle will need to be driven round the block on the street, for example, to calibrate the magnetic-field sensor.

INFORMATION: After successful calibration the routine jumps automatically to the main menu.
