Activating and deactivating alarm system
The alarm system is activated by a ground signal at the activation input or by an activation signal from the hand-held transmitter. The activation of the system is ignored if terminal 86 S, terminal 15 or a valid transponder key is recognised. If for some reason it is not possible to lock the central locking system with a single locking command, the alarm system is not activated. Activation of the alarm system cannot be achieved until the central locking system is locked if necessary manually...
Remedy
Enter the current time again. On-board computer Disconnection of the vehicle battery deletes the memories for average speed and average consumption. As a result, the displayed range on remaining fuel can be markedly different or even 0. The outside temperature indicator loses its memory effect. In other words, the indicated outside temperature can be too high due to the heat radiated when the vehicle is hot. The radio reverts to the Code function when the battery is disconnected and is thus no...
Behaviour in the case of servicing
an activated tilt sensor will trigger an alarm. In order to carry out servicing work the alarm siren must be switched off before the work is commenced. To switch it off, insert the vehicle key with valid transponder into the ignition lock and rotate to actuate the buzzer contact. Components can be removed with triggering the alarm as long as the vehicle key remains inserted. Function display and audible checkback The operating state of the central locking system is fed back via the output Door...
