If an alarm was triggered, the siren emits a brief acoustic signal (see
chapter "Sorting the alarm memory" on page 21).

deactivation, the alarm system has stored an alarm. You can read the alarm memory
and determine the reason for the alarm.
To do this, proceed as follows:
➤ Switch on the ignition and observe the LED on the base of the electronic key
