Access and authorisation system that works through automatic data exchange between key and vehicle, allowing the driver to keep their car key in their pocket or bag at all times. To unlock and open, simply lift the exterior door handle, use a kicking motion underneath the car at the rear of the vehicle or hold down the convenience key. The luggage compartment lid can also be opened when the vehicle is locked. Please note, the keyless entry functionality must initially be activated via the MMI and can be switched on or off if/when required.
