After working on the CA (Comfort Access), in particular on the door handles:
It may be necessary to reset the Car Access System (CAS) control unit.
The following methods are available:

• Using control unit functions under CAS

Note: Reset can be recognised at the START/STOP button.
When resetting the CAS, the START/STOP button illumination is briefly deactivated.
