Entry Lighting
The dome lamp, cargo lamp, and foot lamp inside the vehicle come on when any door is opened, if the dome lamp is in the door position. In addition, these lamps come on when the Remote Keyless Entry (RKE) unlock button is pressed. They stay on for 20 seconds or until a door is opened. After the door is opened and then closed, the light remains on for 20 seconds, or until the ignition is turned to ON/RUN.
