The Parktronic system is activated automatically when you switch on the ignition and the automatic transmission is in drive position D, reverse gear R, or neutral position N. The Parktronic system deactivates at speeds above approximately 11 mph (18 km/h). At lower speeds, the Parktronic system switches on again.
