Dome Lamp The dome lamp will come on when a door is opened. Delayed Entry Lighting Delayed entry lighting lights the vehicle's interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. After all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: Entry Lighting The courtesy lamps will come on and stay on for a set time whenever you press UNLOCK on the remote keyless entry transmitter. The lamps will stay on while a door is opened and then turn off automatically about 25 seconds after it is closed. If the UNLOCK button is pressed and a door is not open, the lamps will turn off after about 40 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 and then turn off. The courtesy lamps are canceled if the ignition key is turned to RUN or START and will not come on unless a door is opened. • 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. 3-16
