SIr Woohoo, Tama ka!
To illustrate further, there are four positions:
"LOCK" - (Where you start to insert the key)
"ACC" - (You can operate accessories like radios and other electrical components)
"ON" - (You can operate almost everything like, Sensors, Powerwindows, Signal lights, Brake lights?, etc)
"START" - (Starts the engine and back to "ON" upon release)
Mahirap kumuha ng picture pag naka engage ang makina and transmission.
At "ON" position (engine not engage), you can check the operation of all lights (Brakes, L/R signals, ParK lights, sensors, etc) by making a 360 degrees visual inspection around the car.
Hope CLaro na ito.
