Exterior lights

LIGHTING CONTROL

Lighting control operation:

1. High beam: With the headlights on, push the lighting control away from the steering wheel to select high beam. The instrument panel warning lamp illuminates. See HIGH BEAM (BLUE).

   NOTES

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

2. 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.

3. 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).

4. Headlights: Rotate the lighting control to this position to switch the headlights on.

5. AUTO: Rotate the lighting control to this position to select auto lights. When the 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), and windscreen wiper detection may also be activated.

   NOTES

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

6. Front fog lights: Operate only while the side lights, headlights, or auto lights are selected. Turn the collar away from the steering wheel and release to switch on. The instrument panel warning lamp illuminates. To switch off the front fog lights, turn the collar away from the steering wheel again, and release. See FRONT FOG LIGHTS (GREEN).

7. Rear fog lights: Operate only while the side lights, headlights, or auto lights are selected. Turn the collar toward the steering wheel and release to switch on. The instrument panel warning lamp illuminates. To switch off the rear fog lights, turn the collar toward the steering wheel again, and release. See REAR FOG LIGHTS (AMBER).

In the event of a bulb failure, it should be noted that some bulbs are replaceable only by a retailer/authorised repairer. See CHANGING A BULB.

DAYTIME RUNNING LIGHTS (DRL)

With the lighting control in the OFF position, the Daytime Running Lights (DRL) switch on automatically under the following conditions:

• The engine is running.

• The gear selector is not in Park (P).

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

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

Unless required or prohibited by law, the DRL can be disabled or enabled by a retailer/authorised repairer.

HEADLIGHT COURTESY DELAY

Headlight courtesy delay operates whenever the lighting control is in the AUTO position and the ignition is switched off. The headlights remain illuminated for up to 240 seconds.

NOTES

The time delay may be changed via the Vehicle settings menu. See INSTRUMENT PANEL MENU.

Press the smart key's headlight button to switch off the courtesy delay feature.

AUTO HIGH BEAM ASSIST (AHBA)

WARNING

The 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 can lead to accidents causing serious injury or death.

NOTES

Do not use Auto High Beam Assist (AHBA) while driving off road.

NOTES

Make sure to defrost the windscreen during winter conditions.

NOTES

Make sure that the forward-facing sensors on the back of the rear-view mirror are not blocked or obstructed.

The AHBA feature can be disabled or enabled via the Vehicle settings menu. See INSTRUMENT PANEL MENU.

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.

For AHBA to become operational, the lighting control must be in the AUTO position (5), with dipped beam headlights selected. See LIGHTING CONTROL.

The instrument panel warning lamp illuminates when AHBA is selected.

AHBA 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).

To manually select high beam, move the lighting control to the high beam position as normal. To return to AHBA, move the lighting control back to the central position.

To manually override to dipped beam from high beam, pull the lighting control to the flash position (2). The AHBA feature cancels. To return to AHBA, push the lighting control to the high beam position (1) and then return it to the central position.

To switch AHBA off, turn the lighting control from AUTO to headlights.

The following may affect the operation of AHBA:

• Highly reflective road signs.

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

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

• Dirty or obscured sensors.

• A dirty, damaged, or misted windscreen.

• Oncoming vehicles partially obscured by a central motorway barrier.

• An icy or frosted windscreen.

NOTES

If the vehicle is fitted with matrix headlights and AHBA is selected, AHBA automatically overrides the Adaptive Front Lighting System (AFS).

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

The headlights have a beam pattern that eliminates the need to mechanically adjust the lights or add any external stick-on decals.

HEADLIGHT LEVELLING

Use the rotary control to set the halogen headlights position to the correct level for the current vehicle load. The control is located on the driver's side, lower fascia.

NOTES

Not available for all markets.

HEADLIGHT LEVELLING – LED AND XENON

LED and xenon headlights fitted with automatic levelling do not require manual adjustment. The vehicle does not have a rotary control on the fascia panel.

ADAPTIVE FRONT LIGHTING SYSTEM (AFS)

When cornering using dipped beam, the Adaptive Front lighting System (AFS) adjusts the headlights beams to provide improved illumination in the direction of travel.

The AFS is deactivated when:

• Reverse (R) is selected.

• The vehicle is stationary.

• The Daytime Running Lights (DRL) are switched on.

If a system fault is detected, the headlights attempt to move to the central position and remain stationary.
