Description And Operation: Description
The exterior lighting system for this vehicle includes the following exterior lamp units:
- Front Fog Lamps
- Optional front fog lamp units are mounted near each outboard end of the front fascia, below the front lamp units. Certain models can be equipped with Light Emitting Diode (LED) fog lamps.
- Rear Lamps
- Optional front fog lamp units are mounted near each outboard end of the rear fascia, below the tail lamp units. Certain models can be equipped with LED fog lamps.
- Headlamps
- The vehicle is equipped with 70 mm double headlights to increase the light intensity and consequently improve visibility in all conditions. When equipped with Bi-Xenon lighting technology (high/low lighting via single high-intensity discharge (HID) bulb), there is twice as much light compared to the use of conventional bulbs, and the 70 mm headlight increases the light intensity by approximately 15% and the lighting depth by approximately 20%. Infrared halogen bulbs are used on the basic versions of the vehicle. The bulbs incorporate a special coating that brings the inside of the capsule to higher temperatures than conventional halogen bulbs, thus providing more light. Certain models will be equipped with LED headlamps.
- STANDARD INFRARED HALOGEN - Equipped with H13 60/55 W bulb. Infrared halogen bulbs are used on the basic versions of the vehicle. The bulbs incorporate a special coating that brings the inside of the capsule to higher temperatures than conventional halogen bulbs, thus providing more light.
- BI-XENON OPTIONAL - The vehicle can be equipped with headlights that use Bi-Xenon technology. The headlights are fitted with next-generation D5S 25W bulbs. The use of these bulbs, despite a lower brightness compared to a 35 W Bi-Xenon bulb, results in a considerable improvement in terms of lighting system complexity, because there are no self-levelling headlight or headlight washer systems, and ballast is not used.
- This vehicle can be equipped with LED headlamps. These are sealed units and the LED bulb array is only serviced with the headlamp assembly.
- License Plate Lamps - Two standard equipment rear license plate lamp units are integral to the light bar and handle assembly, just above the license plate tub. These can also be LED units.
- Rear Light Clusters
- The vehicle's rear light clusters are equipped with LED bulbs that carry out the following functions:
- Side lights;
- Brake lights
- Direction indicators
- Side Marker Lamps
- A side marker lamp is integral to the front fascia forward of each front wheel opening and to the rear fascia behind each rear wheel opening.
- Center High Mounted Stop Lamp - A standard equipment Center High Mounted Stop Lamp (CHMSL) is comprised of an LED array.
- Repeater Lamps - A repeater lamp is mounted to each front fender just behind the front wheel opening.
These exterior lighting lamp units and their controls are combined to provide the following exterior lighting features:
- Automatic Headlamps SMART BEAM
- The system automatically switches (if activated by the customer) from main beam to dipped beam headlights if light sources outside of the vehicle are detected, such as the light from the headlights of vehicles coming in the opposite direction, from the rear lights of vehicles in front or from road lighting. If these conditions are not maintained, the system will automatically switch back to main beam to increase night-time driving safety on poorly lit roads.
The system uses a camera fitted near the interior rear view mirror and in contact with the windshield to process the images and detect the approaching lights or lights in front. When it detects the headlights of an approaching vehicle, the lights of a vehicle in front or ambient light (daylight, street lights and other sources), the Forward Facing Camera (FFC) communicates with the Body Control Module (BCM) via CAN and the BCM deactivates the main beam headlights before they inconvenience other drivers.
The function automatically deactivates (dipped beam headlights active) when the speed is below 20 km/h approx.
- Backup Lamps - The backup (or reverse) lamps include a LED array, reflector and clear lens that are integral to each rear lamp unit.
- Daytime Running Lamps - Daytime Running Lamps (DRL) are standard equipment. When DRL is enabled, the lamps illuminate the clearance (front position or park) lamp bulb in the front combination lamp unit to serve as the DRL. The DRL function can be turned on or off using the Electronic Vehicle Information Center (EVIC) display menus.
- Front Fog Lamps - The optional equipment front fog lamps include the clear bulb, reflector and clear lens of each adjustable front fog lamp unit. Certain models will be equipped with a LED bulb array.
- 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. The hazard lights are activated via a button located on the switch pod.
- Park Lamps - The front park (also known as clearance or position) lamps include the clear bulbs, reflectors and clear lenses integral to the front combination lamp unit. The rear park (tail) lamps include the clear bulbs, reflectors and red lenses integral to each rear lamp unit. Certain models will be equipped with a LED bulb array.
- Turn Signal Lamps - The front turn signal lamps include the amber bulbs, reflectors and clear lenses that are integral to the combination lamp unit. The amber bulbs and clear lenses of the repeater lamps on each front fender are also included in the front turn signal circuits. The rear turn signal lamps include LED bulbs, a reflector and a clear lens that is integral to each rear lamp unit.
Other components of the exterior lighting system for this vehicle include:
- Backup Lamp Switch - This vehicle is equipped with a stand-alone Transmission Range Sensor (TRS) that performs the backup lamp switch function.
- Body Control Module - The Body Control Module (BCM) is located beneath the instrument panel to the left of the steering column in the passenger compartment.
- Brake Lamp Switch - A plunger-type brake lamp switch is located on the brake pedal support bracket under the instrument panel and is actuated by the brake pedal arm when the brake pedal is depressed.
- Clockspring
- The clockspring includes an integral turn signal cancel cam and both the left (lighting) and right (wiper) multi-function switches. The clockspring is located near the top of the steering column, directly beneath the steering wheel.
- Exterior Light Switch
- The exterior light activation switch is located on the left side of the driver side dashboard. The exterior light switch has a knob to manage the following functions:
- Side lights
- DRL
- Auto-light
- Dipped beam headlights
Two switches built into the knob and used to activate the following functions:
- Front fog lights
- Rear fog lights
Two wheels used to control the following:
- Instrument panel backlighting adjustment
- Interior lighting adjustment
- Headlight level if equipped
- Hazard Switch - A momentary push button-actuated hazard switch is integral to the upper instrument panel switch pod located in the center of the instrument panel just below the radio and above the heater and air conditioner controls.
Hard wired circuitry connects the exterior lighting system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the exterior lighting components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes appropriate SYSTEM WIRING DIAGRAMS, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
