Entry Lighting Your vehicle may be equipped with courtesy lamps that will come on and stay on for a set time whenever you press UNLOCK on the remote keyless entry transmitter (if equipped). If you open a door, the lamps will stay on while it's open and then turn off automatically about 25 seconds after you close it. If you press UNLOCK and don't open a door, the lamps will turn off after about 40 seconds. Entry lighting includes a feature called theater dimming. With theater dimming, the lamps don't just 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 won't come on unless a door is opened. 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 RUN. • 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. Delayed Exit Lighting This feature illuminates the interior for a period of time after the key is removed from the ignition. The ignition must be off for delayed exit lighting to work. When the key is removed, interior illumination will activate and remain on until one of the following occurs: Delayed Entry Lighting Delayed entry lighting illuminates the interior for a period of time after all the doors have been closed. • The ignition is RUN. • The power door locks are activated. • An illumination period of 20 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. 3-16
