There are 3 headlamp variants available depending on model specification:

• The Light Emitting Diodes (LEDs) headlamp with DRLs
• Premium LEDs headlamp with signature DRLs
• Matrix LEDs headlamp with signature DRLs (Except NAS).

LOW BEAM

The low beam is controlled manually by the user or automatically by the rain/light sensor. The low beam illuminates when:

• In Power Mode 6 (ignition ON) or higher and the rain/light sensor requests low beam.
• Headlamp delay timeout has been enabled.
• The headlamp button is pressed on the Remote Function Actuator (RFA).
• Remote vehicle location is enabled.

During the activation of high beam, the low beam indicator does not operate in the IPC. Because the low beam and high beam indicator shares the same location in the IPC, and the high beam indicator takes priority. The low beam indicator does not extinguish during high beam flash operation.

HIGH BEAM

The high beam is operated by pushing the left steering column switch towards the instrument panel. The movement interacts with Auto High Beam or Adaptive driving beam.

HEADLAMP LEVELING

Headlamp leveling provides for the adjustment of the vertical aim of the headlamps. The function is to minimize glare to other road users when the vehicle attitude changes due to vehicle loading.

There are 3 types of headlamp leveling system available dependent on the type of headlamp installed to the vehicle:

• Manual headlamp levelling (except NAS)
• Static automatic headlamp levelling
• Dynamic automatic headlamp levelling.

ADAPTIVE FRONT LIGHTING SYSTEM - IF EQUIPPED

AFS modifies the Low beam light distribution.

AUTO HIGH BEAM AND ADAPTIVE DRIVING BEAM

The left steering column switch positions are all connected through a resistive ladder. The output from the resistive ladder is connected to the Steering Wheel Module (SWM) which converts the switch operation to Local Interconnect Network (LIN) signals. The signals are received by the BCM/ GWM which operates the required exterior lighting selection.

Headlamp Flash

The headlamp flash function operates with the ignition ON or OFF. The high beam flash function is operated by pulling the left steering column switch away from the IPC. The non-latching switch operates the high beam headlamps for as long as the switch is held. The switch returns to the high beam OFF position when released. The blue high beam indicator illuminates when the high beam is active.

FRONT FOG LAMP - IF EQUIPPED

Left installation is shown, right installation is similar.

The LED front fog lamps are located in apertures in the front bumper. Each lamp is secured in the bumper with 3 screws. Each fog lamp has an adjuster which is used to set the fog lamp to the correct alignment. The front fog lamp indicator is illuminated in the IPC when the front fog lamps are active.

REAR FOG LAMP

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

Left installation is shown, right installation is similar.

The LED rear fog lamp is located in the rear bumper.

The rear fog lamp indicator is illuminated in the IPC when the rear fog lamps are active.

TURN SIGNAL INDICATORS

The turn signal indicators are operated by moving the left steering column switch up or down to select right or left turn signal indicator respectively. The switch latches in each position.

The switch has a turn signal indicators lane change function. If the switch is gently pushed but not latched, to either turn signal indicators position and then released. The applicable turn signal indicators flash 3 times and then are automatically canceled.

The left steering column switch is only active in Power Mode 6 (ignition ON). The hazard warning lamp switch is active at all times, regardless of the Power Mode. When active, the side repeater lamps flash at a frequency cycle of 400 milliseconds ON and 400 milliseconds OFF.

If a turn signal indicator fails, the green warning indicator in the IPC flashes at twice the normal rate. The audible ticking from IPC sounder is also at twice the normal rate.

If a trailer is connected to the vehicle, the trailer turn signal indicators flash at the same frequency operates as the vehicle turn signal indicators.

SIDE REPEATER LAMP

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

Left installation is shown, right installation is similar.

The side repeater lamps are located in the door mirrors. The side repeater lamps use LEDs.

The side repeater lamps have the same functionality as the front and rear turn signal indicators. The side repeater lamps are operated by the left steering column switch or by the hazard warning lamp switch. When a side repeater lamp fails, the turn signal indicators continue to flash at the normal rate.

HAZARD WARNING LAMP

NOTE: RHD vehicle is shown, LHD vehicle is similar.

The hazard warning lamps are controlled by a non-latching switch in the center of the instrument panel. The hazard warning lamps operate at all times when selected and are not dependent on the Power Mode.

When the hazard warning lamps are selected ON, all of the turn signal indicators operate as previously described.

Both turn signal indicators in the IPC also flash. The hazard warning lamps flash at a rate of 400 milliseconds ON and 400 milliseconds OFF. When the hazard warning lamps are active, they override any request for turn signal indicators operation.

If a trailer is connected to the vehicle, the trailer turn signal indicators flash at the same frequency operates as hazard warning lamps.

The hazard warning lamps can also be enabled by an impact signal from the Restraints Control Module (RCM). This is received by the BCM/ GWM which enables the hazard warning lamps. The hazard warning lamps can be canceled when impact mode is canceled by the RCM.

TRAILER LIGHTING

NOTE: Several different types of trailer socket can be installed to the vehicle depending on market specifications.

The BCM/ GWM monitors the turn signal indicators and can detect when more than 2 lamps are installed. When a trailer is detected, the trailer warning indicator in the IPC flashes in synchronization with the turn signal indicators.

If 1 or more of the turn signal indicators on the vehicle or the trailer are defective, the trailer warning indicator does not flash. This provides an alert for the driver of a failure.

RAIN/LIGHT SENSOR

The automatic headlamp system uses a rain/light sensor which is connected to the BCM/ GWM through a LIN. The BCM/ GWM reacts to the signals from the rain/light sensor and enables the exterior lighting as required.

The light sensor is incorporated in the rain/light sensor which is located on the inside of the windshield, below the Rear View Mirror. The wiper system also uses the rain/light sensor for automatic wiper operation.

The height of the rear suspension can be adjusted manually by using the buttons located on the left of the loadspace.

The rear height adjust feature is useful when loading or unloading the vehicle, connecting or disconnecting a trailer.

The rear height adjust feature operates for a short period of time in Power Mode 0 (ignition OFF). The feature stops operating when in Power Mode 6 (ignition ON).

The rear height adjust feature can also be operated through the smart key.

HEIGHT SENSORS

The front and rear height sensors are used by the headlamp leveling system.

IMAGE PROCESSING MODULE

The IPMA is a module that has an integrated forward facing camera with the lens directed through the windshield. The IPMA is located above the rear view mirror behind the rear view mirror covers. The IPMA is attached to a bracket, which is bonded to the windshield.

The IPMA is used to identify oncoming vehicles and other objects to control the Auto High Beam and the Adaptive Driving Beam.

The camera is a low resolution image sensor that detects headlamps and tail lamps of the vehicles ahead. The IPMA evaluates the image data, checking for light intensity and location. Depending on the image data, the IPMA then sends a low or high beam request to the BCM/ GWM. The signals are sent through the HS CAN underbody (UN) system bus.
