Vdiag No.: 0F
Locking / Unlocking
This system can function with up to four remote control units (the UCH can only manage four different codes).
The radio frequency signal receiver is integrated in the UCH.
The central door locking button is inhibited once the doors have been locked by the remote control.
Locking and unlocking the doors with the remote control is confirmed by the hazard warning lights flashing (if all the
doors are closed properly):
– locking: 2 flashes,
– unlocking: 1 flash.
Depending on the equipment level, unlock the doors and ensure that none of the doors is opened within the next
30 seconds otherwise the system will automatically re-lock the vehicle opening elements (without the hazard
warning lights flashing).
The UCH controls the vehicle interior lighting. If a courtesy light is left on, the UCH will cut the lighting supply after
a period of approximately 30 minutes.
The Top of the range version dims the light progressively after the doors have been closed by radio frequency
remote control.
Spare keys are supplied without a code or a number.
It is possible in the event of a key being stolen or lost or at the customer's request, for a vehicle key to be de-
allocated.
It can be reassigned to the same vehicle if necessary.Note:
Unlocking can be performed by the UCH, if the airbag computer has detected an impact or if it is faulty (see 88C,
Airbag - Seat belt pretensioners).
