The PDC control unit performs a system test after the ignition has been turned on. The parking aid is ready for operation on successful completion of the system test. The parking aid is activated automatically by engaging reverse gear. A delay of approximately 1 second is programmed on both automatic and manual transmission vehicles. The purpose of the delay in activating the PDC when engaging reverse gear on vehicles with an automatic transmission is to prevent unintentional activation of the PDC when passing through the R-position when changing the drive stage. The delay on manual transmission.
