Technical Background
Concept-related restrictions
1. Advanced key functions can temporarily be disabled by interference from transmitters in
close proximity to remote key, using the same frequency range (e.g. cell phones, wireless
headphones, other vehicle keys etc.) as no positive identification is possible.
2. If the customer reaches into the door
handle while touching the lock sensor
to lock the vehicle it will not be
locked. This is because the unlocking
command from the sensor is sent at
the same time and has a higher
priority.
Figure 1. Reaching into door handle while
touching the lock sensor.
3. The Advanced key system needs a short response time for the key identification. When
grabbing and pulling the door handle very quickly, the key may not yet be identified and the
vehicle does not unlock.
4. Unlocking the door after locking it is not possible for a brief period. This allows the customer
to check that the door is locked by pulling the handle.
5. To reduce power consumption, the door handle touch sensors are deactivated after the
vehicle has been parked for a few days. It is then necessary to first wake the vehicle by
pulling the door handle once and then a second time to open the vehicle. In this situation,
locking the vehicle with advance key is only possible after an ignition cycle.
6. If the vehicle battery is discharged, the energy management system gradually deactivates
unnecessary convenience functions. It is possible that you will temporarily not be able to
unlock your vehicle using Advance key.
