A driver message appears in the instrument cluster display if there is no remote control vehicle key inside the vehicle or if the system does not recognize the remote control vehicle key. The key may not be recognized, for example, if it is covered by something that interferes with the signal (such as a briefcase), or if the remote control vehicle key battery is weak. Electronic devices such as mobile phones can also interfere with the signal.
Dirt on the door handles that contains a lot of salt (especially in winter) can affect the way the
door handle sensors work. Cleaning the door handles can help with this problem ⇒ page 334, Exterior care and cleaning.
If the automatic transmission is not in Park (P) position, the electronic steering column lock will not lock and the vehicle will not lock via sensors in the front door handles or the remote control vehicle key.
