Operation
The car is equipped with a burglar alarm comprising a control unit, movement detector, siren and transmitters (switches) in the hood (bonnet), doors and luggage compartment lid. For particulars of the operation of the control unit, i.e. the activation times for the alarm, the time during which the siren will sound when the alarm is set oft, etc. see the separate instruction manual for the burglar alarm.

The control unit is supplied (+30) from fuse 24 across the white 29-pole connector i52A, pin 4 of the central locking control unit 175, pin 30 of relay 151 and pin 1 of control unit 289, regardless of the position of the ignition switch, and from pin 9 (+X) when the ignition switch is in the parked, drive or start position.

If the burglar alarm is activated (LED 305 flashes), the alarm will be set off if movement detector 304 is activated or if one of the following contacts should close:

- Door switches 54 connected to pin 3. (Time-delay relay 151 for the interior lighting only affects the activation time of about 15 5 for the alarm.)

- Luggage compartment light switch 56 or the bonnet switch, which are connected to pin 5.

When the alarm is set off, the siren will be supplied via pin 6 and will sound.

The movement detector can be switched off by means of ON/OFF switch 288 connected to pin 10 (contacts will close).

If one of the seat switches 314 or 315 is closed at the same time as the ignition switch is in the parked, drive or start position, LED 305 will be switched off.

A receiver for remotely controlled de-activation can be connected to white connector 57A. A transmitter designed to initiate an alarm in a portable receiver can be connected to red connector 57B.
