Principle of Operation

Inserting, Locking and Releasing Remote Controls in Ignition Switch

The vehicle can be started with the remote controls or with the reserve key:

1. Inserting: push the remote control into the ignition switch.
2. Pressing the remote control: the sensor detects a user request to lock the remote control in the ignition switch.
3. Identification of the transponder by the CAS.
4. Locking the remote control in the ignition switch: when the remote control is recognized as authorized, the electromechanical removal lock is activated.
The remote control is mechanically fixed in place (locked). Locking of the remote control in the ignition switch is verified by a hall sensor in the CAS.
This ensures that the vehicle can be locked with the key in the case of a system failure.
5. Terminal R "on": after the remote control is locked in the ignition switch, terminal R is automatically switched on.

Automatic Ejection of a Remote Control

A remote control recognized as invalid cannot be locked (e.g. the key of another vehicle) If the transponder is invalid, the remote control will be pushed out.

Removing the Remote Control

The remote control can only be removed when the vehicle is stopped (below 1km/h) and the engine is switched off.

If these conditions are met, then the remote control can be removed in any terminal status by pressing the remote control. When pressed, the sensor in the CAS detects a request for release.

The CAS control unit actuates the electromechanical removal lock. The remote control is pushed out with spring force. After releasing the removal lock, the CAS is always in the position terminal R "off."

The remote control may also be "comfort released" by pressing the start/stop button for longer than 2 seconds after shutting off the engine.
