Exterior lights

EXTERIOR LIGHTS OVERVIEW

The lighting system operates automatically depending upon the ambient lighting conditions. The system selects the appropriate lighting function, dipped beam or Daytime Running Lights (DRL), for the conditions that the system detects. In some circumstances, it may be necessary to manually override automatic operation. Some manual operations are not possible due to vehicle activity or legislative requirements.

LIGHTING CONTROL

  1. Neutral position: The lighting system operates automatically, dependent on the ambient level of light. During daylight, the Daytime Running Lights (DRL) automatically switch on. During low ambient light, the headlights switch on automatically. To manually switch on any lighting functions, rotate the lighting control to the required position and release. After being released, the lighting control returns to the neutral position.

  2. Side lights: Rotate the lighting control to this position to switch the side lights on. The instrument panel warning lamp illuminates. See SIDE LIGHTS (GREEN).

  3. Headlights OFF: Rotate the lighting control to this position to switch the headlights off.

  4. Headlights: Rotate the lighting control to this position to switch the headlights on. See DIPPED BEAM (GREEN).

  5. AUTO: Rotate the lighting control to this position to select AUTO lights. When ambient light fades and the ignition is switched on, the side lights, rear lights, dipped beam headlights, and number plate lights switch on automatically. Headlight courtesy delay, Auto High Beam Assist (AHBA), Adaptive Driving Beam (ADB), the Adaptive Front lighting System (AFS), and wiper detection may also be activated.

    NOTES

    Low ambient light levels, caused by adverse weather conditions, may also cause the auto lights to activate.

  6. High beam: With the headlights on, push and release the lighting control to select high beam. See HIGH BEAM (BLUE).

    Push and release the lighting control again to deselect high beam.

    NOTES

    Do not use high beam where it may distract other road users.

  7. High beam flash: Pull the lighting control toward the steering wheel and release to flash the high beam on and off. High beam remains on for as long as the lighting control is held.

  8. Front fog lights: Turn the lighting control away from the steering wheel, and release to switch on the front fog lights. The instrument panel warning light illuminates. See FRONT FOG LIGHTS (GREEN).

    Turn the lighting control away from the steering wheel again, and release to switch off the front fog lights.

  9. Rear fog lights: Operate only while the headlights or front fog lights are selected. Turn the lighting control toward the steering wheel and release to switch on the rear fog lights. The instrument panel warning lamp illuminates. See REAR FOG LIGHTS (AMBER).

    Turn the lighting control toward the steering wheel again, and release to switch off the rear fog lights.

DAYTIME RUNNING LIGHTS (DRL)

During normal daylight operation, the Daytime Running Lights (DRL) operate automatically, with the lighting control in the AUTO position.

DRL switch on automatically under the following conditions:

  • The engine is running.

  • The gear selector is out of Park (P).

  • The Electric Parking Brake (EPB) is not applied. Market dependent.

  • Auto lights are selected and high ambient light levels are detected.

Turn the lighting control to the OFF position to switch off the DRL. DRL can be manually switched off only when the vehicle is stationary and the engine is running. DRL reactivates when the vehicle's speed increases above 10 km/h or the vehicle covers a distance of 100 m. Repeat the process to switch off the DRL during a journey.

AUTO HIGH BEAM ASSIST (AHBA)

WARNING

The Auto High Beam Assist (AHBA) system cannot be relied upon to activate or deactivate high beam in all potential circumstances. The driver remains responsible for the correct use of the headlights at all times. Incorrect use of the headlights may cause an accident, potentially resulting in serious injury or death.

WARNING

The forward-facing sensors are mounted on the rear of the rear-view mirror. Keep this area of the vehicle clean and free from obstructions, e.g., stickers, debris, mud, snow, or ice. Failure to do so can lead to accidents, potentially resulting in serious injury or death.

The AHBA system automatically selects and deselects high beam, under specific conditions of road lighting and in the absence of other vehicle lights. The system is only active when the ambient light drops below a predetermined level. AHBA is enabled when the lighting control is in the AUTO position.

The driver can disable and re-enable the AHBA system at any time via the touchscreen:

  1. Touch the settings icon¹ from any screen.

  2. Touch the ALL soft key.

  3. Touch Vehicle.

  4. Touch Exterior Lights.

  5. Automatic high beam assist: Toggle on or off. Toggle on to activate and view the available options.

  6. Touch the exit icon², after selection, to return to the previously displayed screen.

The AHBA system only activates when the vehicle's speed exceeds 40 km/h (25 mph). The system deactivates when the vehicle's speed drops below 24 km/h (15 mph).

Push and release the lighting control to manually override to dipped beam from high beam. Rotate the collar to AUTO to return to AHBA. The instrument panel warning lamp illuminates. See AUTO HIGH BEAM ASSIST (AHBA) (BLUE).

Push and release the lighting control to manually select high beam. Rotate the lighting control to AUTO to return to AHBA.

The following may affect the operation of the AHBA system:

  • Highly reflective road signs.

  • Dimly lit road users, e.g., cyclists or pedestrians.

  • Adverse weather conditions, e.g., rain or fog.

  • A dirty or obscured sensor.

  • A dirty, damaged, or misted windscreen.

  • Oncoming vehicles, partially obscured by a central motorway barrier.

  • An icy or frosted windscreen.

WINDSCREEN WIPER DETECTION

If AUTO lights is selected and the windscreen wipers are switched on for 20 seconds or more, the side lights, tail lights, and headlights switch on automatically. When the wipers are switched off, the lights automatically switch off 2 minutes later.

EXTERIOR LIGHTS CONDENSATION

Condensation in the headlights, direction indicators, or rear lights is a natural phenomenon.

Condensation can occur under certain atmospheric conditions or after washing the vehicle. The performance and life expectancy of the lights is not affected.

Condensation should partially or completely clear, with regular use of the lights, within 48 hours of dry atmospheric conditions.

LED lights distribute less heat towards the outer lens than halogen or xenon lights. In extreme conditions, LED lights may take longer to clear, but this is not detrimental to the performance of the light.

DRIVING ABROAD

Headlight alignment must be correct for the country in which the vehicle is travelling.

Headlight alignment can be checked and overridden, if required, via the touchscreen as follows:

  1. Touch the settings icon.¹

  2. Select All.

  3. Select Vehicle.

  4. Select Exterior Lights.

  5. Select Driving Side.

  6. Select a driving side option.

  7. Touch the exit icon.²

Settings icon.¹

Exit icon.²

NOTES

Some headlights feature a beam pattern that eliminates the need for re-alignment.

NOTES

The headlight alignment setting is re-applied at the start of each new vehicle ignition cycle.

WARNING

Failure to adjust the headlights may result in the dazzling of oncoming drivers, which could lead to an accident, potentially causing serious injury or death.

NOTES

Correct headlight alignment is a legal requirement.

NOTES

Local restrictions may prohibit headlight re-alignment in some markets. Contact a retailer/authorised repairer for more information.

ADAPTIVE FRONT LIGHTING SYSTEM (AFS)

The Adaptive Front lighting System (AFS) is active when the lighting control is in the AUTO position and dipped beams are switched on.

The AFS is deactivated when high beam is selected or dipped beam is not operating in AUTO mode, or when the vehicle is in Park (P).

While operating as an AFS, the dipped beams are automatically adjusted to suit the vehicle's speed and weather conditions:

  • Country mode: A standard headlight beam that operates at vehicle speeds between 0 and 110 km/h (0 to 70 mph) when an urban environment is not detected. If an urban environment is detected, country mode operates from 48 km/h (30 mph).

  • City mode: A wider headlight beam that operates at vehicle speeds up to 48 km/h (30 mph) when an urban environment is detected.

  • Highway mode: A raised headlight beam that operates at vehicle speeds above 110 km/h (70 mph).

  • Adverse weather mode: Operates when the windscreen wipers are active for more than 2 minutes and the vehicle’s speed is below 64 km/h (40 mph).

If a system fault is detected, the headlights attempt to adopt the default beam pattern and then remain there. The instrument panel displays a message to indicate that a fault is present.

ADAPTIVE DRIVING BEAM (ADB)

WARNING

The Adaptive Driving Beam (ADB) system cannot be relied upon to activate or deactivate high beam in all possible circumstances. The driver remains responsible for the correct use of the headlights at all times. Incorrect use of the headlights may cause an accident, potentially resulting in serious injury or death.

WARNING

The forward-facing sensors are mounted on the rear of the rear-view mirror. Keep this area of the vehicle clean and free from obstructions, e.g., stickers, debris, mud, snow, or ice. Failure to do so can lead to accidents, potentially resulting in serious injury or death.

ADB activates automatically once the vehicle's speed reaches 40 km/h (25 mph) and the camera does not detect an urban environment. ADB automatically deactivates when the vehicle's speed slows to 24 km/h (15 mph), when ambient light exceeds a predetermined level or when the gear selector is in Reverse (R).

ADB is defined as a system that evaluates the road scene ahead of the vehicle. ADB automatically adapts the light distribution according to the position of the preceding and oncoming traffic. ADB is enabled when the lighting control is in the AUTO position and the ambient light level is below a predetermined level.

NOTES

When ADB is active, the blue high beam indicator lamp remains illuminated, as the headlights will deploy partial or full high beam at this time. See HIGH BEAM (BLUE).

The driver can disable and re-enable the ADB system at any time via the touchscreen:

  1. Touch the settings icon¹ from any screen.

  2. Touch the ALL soft key.

  3. Touch Vehicle.

  4. Touch Exterior Lights.

  5. Adaptive Driving Beam: Toggle on or off.

  6. Touch the exit icon², after selection, to return to the previously displayed screen.

Pull and release the lighting control to manually override to dipped beam from ADB. The instrument panel warning lamp illuminates.

Push and release the lighting control to return to ADB. The instrument panel warning lamp illuminates. See DIPPED BEAM (GREEN).

Repeated pushing of the lighting control toggles the operation of the high beam between automatic and manual.

Rotate the lighting control to the dipped beam position to switch the ADB system off.

The following may affect operation of the ADB system:

  • Highly reflective road signs.

  • Dimly lit road users, e.g., cyclists or pedestrians.

  • Adverse weather conditions, e.g., rain or fog.

  • A dirty or obscured sensor.

  • A dirty, damaged, or misted windscreen.

  • Oncoming vehicles, partially obscured by a central motorway barrier.

  • An icy or frosted windscreen.
