Ignition Key Removed (Rest Status)

When the parking brake is applied, the P-light remains on for a certain period indicating "brake hold" to the driver. The parking brake can be released at any time by pressing the push button until the ignition key is removed (car wash function)  . The rest status is assumed when the ignition key is removed. The parking brake can not be released when the ignition key removed (child safety). The ignition key must be inserted and the ignition switched on to release the parking brake.
