Interior Lamps Instrument Panel Intensity/Brightness Control Courtesy Lamps When any door is opened, several lamps go on. They make it easy for you to enter and leave the vehicle. You can also turn these lamps on by sliding the PANEL LIGHTS switch to INT (Interior). 1 The instrument panel intensity can be adjusted by moving this lever between LO and HI. The instrument panel lights will be on only when the headlamps are on. The interior courtesy lamps can be turned on by sliding the lever all the way to the right. Delayed Entry Lighting When you open the door, the interior lamps will turn on. When you close the door with the ignition off', the interior lamps will stay on for 25 seconds or until the ignition is turned to an on position. Note that locking the doors will override the delayed entry lighting feature and the lamps will turn off right away. Theater Dimming This feature allows for a three to five-second fade out of the courtesy lamps instead of immediate turn off. Time Out Feature(If Equipped) On vehicles equipped with the Remote Keyless Entry system, the interior lamps will automatically shut off after a 10 minute period if a door is left ajar or if the interior courtesy lamp switch has been left in the INT (on) position. This feature is designed to help eliminate battery wear down. Delayed Exit Lighting With this feature, the interior lamps will turn on and stay on for up to 25 seconds after you remove the key from the ignition. This will give you time to find the door pull handle or lock switches. 2-44
