approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble. ◀

ice center after it is replaced to ensure that all
comfort functions are available without restric‐
tions and that any associated Check Control
messages are no longer displayed.
