If the dome lamp override button is in the out position, the lamps inside the vehicle automatically come on when any door is opened or when the Remote Keyless Entry (RKE) unlock button is pressed. After the door is opened the lights remain on and stay on for 20 seconds after the doors are closed, or until the key is put into the ignition and turned to the ACC/ACCESSORY position. The lights will then gradually dim until they are no longer lit.
