The entry lighting system turns on the reading and dome lamps and the backlighting to the exterior lamp control when a door is opened or if you press the remote keyless entry transmitter unlock button. If activated by the transmitter, the lighting will remain active for about 25 seconds. The entry lighting system uses the light sensor; it must be dark outside in order for the lamps to turn on. The lamps turn off about 25 seconds after the last door is closed. They will dim to off if the ignition is on, or immediately deactivate if the power locks are activated.
