- Headlamp Time Delay - On vehicles equipped with the automatic headlamps option, when this feature is enabled the low or high beam headlamps remain illuminated for a programmable delay interval of 0 (disabled), 30, 60 or 90 seconds after the ignition switch has been turned to the OFF position. This feature is customer programmable using the Electronic Vehicle Information Center (EVIC) switches and the U-Connect Touch(TM) screen module in the Integrated Center Stack (ICS).
- Headlamps With Wipers - Vehicles with the automatic headlamps option have an automatic headlamps-with-wipers feature. When this feature is enabled and the AUTO position of the headlamp switch is selected, the headlamps are turned ON automatically whenever the windshield wipers are turned ON; and, if the headlamps were turned ON automatically when the wipers were turned ON, they will also turn OFF automatically when the wipers are turned OFF if the appropriate ambient light conditions exist. This feature is customer programmable using the Electronic Vehicle Information Center (EVIC) switches and the U-Connect Touch(TM) screen module in the Integrated Center Stack (ICS).
- Mirror Courtesy Lamps - Vehicles with these lamps illuminate a Light Emitting Diode (LED) unit behind the outer edge of each outside rear view mirror glass in conjunction with the interior courtesy lamps.
- Optical Horn - Also known as flash-to-pass, the beam selection function of the multi-function switch control stalk has a momentary intermediate position that allows the headlamp high beams to be flashed momentarily, without changing the headlamp beam selection.
- Park/Tail Lamps - The front park lamps include the amber bulbs, reflectors and clear lenses of each park lamp and the clear bulb and amber lens of each front side marker lamp integral to each front lamp unit. The rear tail lamps include the multiple Light Emitting Diode (LED) units, a reflector and a red lens integral to both the outer and center portions of each rear lamp unit, the clear bulbs and red lenses of each rear side marker lamp as well as the bulb and clear lens of the license plate lamp unit.
