Lighting The reading lamps, located on the headliner above the rearview mirror, can be turned on or off independent of the automatic courtesy lamps, when the doors are closed. Dome Lamp Override The dome lamp override button is next to the exterior lamps control. E (Dome Lamp Override): Press the button in and the dome lamps remain off when a door is opened. Press the button again to return it to the extended position so that the dome lamps come on when a door is opened. 6-5 Lighting Features Entry Lighting For vehicles with courtesy lamps, they come on and stay on for a set time whenever the unlock symbol is pressed on the Remote Keyless Entry (RKE) transmitter, if the vehicle has one. If a door is opened, the lamps stay on while it is open and then turn off automatically about 20 seconds after the door is closed. If the unlock symbol is pressed and no door is opened, the lamps turn off after about 20 seconds. Entry lighting includes a feature called theater dimming. With theater dimming, the lamps do not turn off at the end of the delay time. Instead, they slowly dim and then go out. The delay time is canceled if the ignition key is turned to ON/RUN or the power door lock switch is pressed. The lamps will dim right away. Dome Lamps The dome lamps are located in the overhead console and above the rear seat passengers. The dome lamps automatically come on when a door is opened, unless the dome lamp override button is pressed in. The lamps can also be turned on and off by turning the instrument panel brightness control clockwise to the farthest position. Reading Lamps Press the button near each lamp to turn them on or off.
