Turn the ring to the 
position (the license plate lighting comes on at the same time).
Canadian models: If the ignition is in position II or the engine is running, the daytime running lights will also be on.
With the ring in this position, the parking lights will remain on even when the ignition is switched off, however, the rear parking lights will not be on if the ignition is in model 0.
In dark ambient lighting conditions, the rear parking lights also illuminate when the tailgate is opened to alert anyone traveling behind your vehicle. This happens regardless of the position that the headlight control is in or which mode the ignition is in.
