The document addresses open issues and comments regarding UN R11 and GTR No. 1 concerning emergency door opening. It proposes defining vehicle master control switch as the device bringing onboard electronics from off to normal operation mode, and suggests activating this switch rather than switching ignition on in test procedures. The document defines main power supply as power source(s) and supply path(s) normally used for door system operation, excluding secondary or back-up supply. It raises concerns about secondary or back-up power supply failure occurring in the field before emergencies despite compliant test results. The document discusses objective intuitiveness criteria including visibility, accessibility, discoverability, identification, and operability. It recommends standardized marking for exterior door handles and proposes that door opening and closing procedures be described in vehicle owners’ manuals.
