Entry Lighting Your vehicle may have courtesy lamps that will 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 will stay on while it is open and then turn off automatically about 25 seconds after the door is closed. If the unlock symbol is pressed and you do not open a door, the lamps will 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 after the delay time until they go out. The delay time is canceled if you turn the ignition key to ON or press the power door lock switch. The lamps will dim right away. When the ignition is on, illuminated entry is inactive, which means the courtesy lamps will not come on unless a door is opened. Delayed Entry Lighting Delayed entry lighting illuminates the interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. Immediately after all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: • The ignition is in ON. • The doors are locked. • An illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on because a door is open. 187
