Security Code: Notes

The security code function prevents unauthorized persons from starting the engine. This function is controlled from the MID/MFD. The driver can select and enter a code, without which subsequent starting of the engine is prevented. This function can be used if the vehicle is to left unattended for a long period of time, i.e. airport car park. Each time the code is activated, it is only valid until the next time the engine is started. If the code is not available or forgotten, emergency deactivation is possible.

The CODE is a four digit number which can be entered with the ignition at position I (AUX). If the vehicle is parked with the code armed, starting of the engine is inhibited until the correct code is entered to disarm the alarm. If the incorrect code is entered, the alarm horn is activated and the immobilization ECU prevents starting. This is performed by messages sent on the K bus to the BCU. The BCU electrically controls the alarm horn and the immobilization ECU functions.

The code can be selected on the MID and activated as follows:
