The Forward Facing Camera Module (FFCM) has programming that allows it to detect light levels, their color and their source within the path ahead of the vehicle. When the headlamp switch is set to auto, the high beam position of the headlamp dimmer switch is selected, and the ambient light conditions are appropriate, the headlamp high beams are turned ON and OFF automatically as needed. If the vehicle is not equipped with the FFCM, review SmartBeam Automatic Headlamps.
• SmartBeam® Automatic Headlamps  - Vehicles equipped with the automatic (auto low) headlamp system may also have the SmartBeam® automatic (auto high) headlamp option available. SmartBeam® includes a unique digital light-sensing imager camera integral to the electrochromic inside rear view mirror (if equipped) and programming that allows it to detect the light levels, their color and their source within the path ahead of the vehicle. When SmartBeam® is enabled, the AUTO (Automatic) position of the headlamp switch is selected, the high beams are selected with the multi-function switch control stalk being pushed forward and the headlamp high beams will be turned ON and OFF automatically as needed.
• Backup Lamps  - In domestic market vehicles, the backup (or reverse) lamps include a clear bulb, reflector and clear lens that are integral to each inner and outer rear lamp unit. In export market vehicles, backup lamps are found in only the two inner rear lamp units.
• Brake Lamps  - The brake (or stop) lamps include a clear bulb, reflector and a red lens that are integral to each outer rear lamp unit, and the red lens and multiple Light-Emitting Diode (LED) units of the CHMSL. On vehicles equipped with combined rear lighting, the turn signal and stop lamp use the same single bulb filament. When combined rear lighting is preset, turn signals are allowed to interrupt stop lamp actuation to allow turn signal actuation.
• Daytime Running Lamps  - Domestic market vehicles with HID front lamp units and DRL illuminate a dedicated DRL bulb in the front lamp unit, while export market vehicles illuminate a combination DRL/position lamp bulb in each front lamp unit. If allowed by law in the country in which the vehicle was purchased the Daytime Running Lights can be turned on and off using the Uconnect® System.
• Exterior Lamp Fail-Safe Operation  - The ElectroMechanical Instrument Cluster (EMIC) and the Body Control Module (BCM) provide a fail-safe feature which will automatically turn ON the low beam headlamps and all park lamps when the ignition switch is in the ON position and there is no detected input from the headlamp switch, or when there is no communication over the Controller Area Network (CAN) data bus.
• Exterior Lamp Load Shedding  - The BCM provides a battery saver feature which will automatically turn OFF all exterior lamps that remain ON with the ignition switch in the LOCK position after a timed interval of about eight minutes.
• Front Fog Lamps  - The optional front fog lamps include the bulb, reflector and lens of each adjustable front fog lamp unit. Certain models receives LED fog lamps in place of the halogen lamps.
• Hazard Warning Lamps  - The hazard warning lamps include the bulbs, reflectors and lenses of each lamp in the right and left, front and rear turn signal circuits.
• Headlamp Delay  - The low or high beam headlamps remain illuminated for 90 seconds after the ignition switch has been turned to the OFF position. If the vehicle is equipped with the optional Electronic Vehicle Information Center (EVIC), the delay interval is customer-programmable for 0, 30, 60 or 90 seconds.
• Headlamps  - Multiple headlamp systems are available on this vehicle for domestic markets. The standard halogen headlamp system includes two single filament halogen bulbs in each front lamp unit, one low beam and one high beam. The LED headlamp is available as a standard option on certain models. The optional HID headlamp system includes a single HID lighting element/igniter unit for low or high beam headlamps. An electric motor and mechanism internal to the HID lamp unit closes a shutter for low beams and opens the shutter for high beams. The HID front lamp units each include an electronic ballast module, while an Automatic Headlamp Leveling Module (AHLM) that serves both front lamp units levelling motor. Both headlamp systems also include an adjustable reflector and clear lens integral to each front lamp unit.
• Headlamp Leveling  - On all vehicles equipped with optional HID headlamps, an Automatic Headlamp Leveling Module (AHLM) controls a headlamp leveling actuator motor on each front lamp unit to automatically perform headlamp adjustments using inputs from front and rear axle sensors to monitor changes in the vehicle suspension height. On vehicles equipped with manual headlamp levelling, the BCM directly drives both of the headlamp motors.
• 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 Lamps  - The front park lamps include either the amber bulbs, the reflectors and the clear lenses of the park lamp compartment in both front lamp units or the clear position lamp bulb within the headlamp compartment of both front lamp units. On vehicles not equipped with repeater lamp units, the front lamps also include the front side marker lamp bulbs and amber reflectors. On vehicles equipped with repeater lamp units, only the amber side marker reflectors are retained in the front lamp units. The rear park lamps include a clear bulb, a reflector and a red lens integral to each inner and outer rear lamp unit as well as the clear bulbs and lenses of the two license plate lamp units.
• Rear Fog Lamps  - Rear fog lamps are available only in certain export markets where they are required equipment. The rear fog lamps include a clear bulb and a red lens and reflector that are integral to each rear fog lamp unit located below the outer tail lamps in the rear fascia. On domestic market vehicles, only the red reflector is retained in the rear fascia.
• Turn Signal Lamps  - The front turn signal lamps include an amber bulb, a reflector, and a clear lens that are integral to each front lamp unit. On vehicles equipped with the optional outside mirror signal lamps, there are several amber LED units integral to each mirror signal lamp unit that are also activated by the turn signal circuits for the same side of the vehicle. Depending upon market requirements, either the front side marker lamps or the repeater lamps on each front fender will also be included in the front turn signal circuits. Depending upon market requirements, the rear turn signal lamps include either a clear bulb and a red lens or an amber lens and a reflector that are integral to each outer rear lamp unit. On vehicles equipped with combined rear lighting, the turn signal and stop lamps use the same bulb filament. When combined rear lighting is preset, turn signals are allowed to interrupt stop lamp actuation to allow turn signal actuation.
