KEYLESS-GO is an electronic drive authorisation system. Drivers carrying a key with integrated KEYLESS-GO transponder need only pull the door handle to open the door. The engine can be started and switched off using the start/stop button on the selector lever.

And the car can be conveniently locked from the outside with the help of the locking function: a press of the button on the door handle is all it takes. KEYLESS-GO is available as standard on all SL models.
