| General information on entry and start authorisation control unit „Advanced Key“ |
| The „Advanced Key“ is available as an optional extra for vehicles with the immobilizer V. The concept was adopted from vehicles with the immobilizer IV, though optimisation has meant that the number of system components required has been reduced. |
| The central locking buttons on the exterior door handles have been discontinued. Locking and unlocking are activated by touching the capacity sensors on the exterior door handle. |
