Malfunction

Comfort Access may not function properly if it experiences interference from external sources such as mobile phones, metal objects, overhead power lines, transmission towers, etc.

If this occurs, open or close the vehicle using the buttons on the remote control or use a key in the door lock.

To subsequently start the engine, hold the remote control against the marked area on the steering column.
