Active bending lights*
Active bending lights are designed to provide additional illumination in bends and junctions. Cars with LED* can have active bending lights, depending on the car's equipment level.
Active main beam
Active main beam is a function which uses a camera sensor at the top edge of the windscreen to detect the headlamp beams from oncoming traffic or the rear lights of vehicles in front, and then switches from main beam to dipped beam.
Using direction indicators
The car's direction indicators are operated with the left-hand stalk switch. The direction indicator lamps flash three times or continuously, depending on how far up or down the stalk switch is moved.
The brake light automatically comes on during braking.
Rear fog lamp
The rear fog lamp is considerably stronger than the normal rear lights and should only be used in reduced visibility due to fog, snow, smoke or dust so that other road users have an early warning of a vehicle ahead.
When driving with the stalk switch's rotating ring in the position, dipped beam is activated automatically in weak daylight or darkness or when the car's electrical system is in ignition position II.
Using main beam
Main beam is operated with the left-hand stalk switch. Main beam is the car's strongest lighting and should be used when driving in the dark for better visibility, as long as it does not dazzle other road users.
Using home safe lighting
Some of the exterior lighting can be kept switched on to work as home safe lighting after the car has been locked.
Emergency brake lights
Emergency brake lights are activated to alert vehicles behind about heavy braking. The function means that the brake light flashes instead of - as in normal braking - shining with a constant glow.
Position lamps can be used so that other road users can see the car if it stops or is parked. The position lamp is switched on with the rotating ring on the stalk switch.
Approach light duration
Approach lighting is switched on when the car is unlocked and is used to switch on the car's lighting at a distance.
Hazard warning flashers
Hazard warning flashers warn other road users by means of all of the car's direction indicators being activated simultaneously. The function can be used to give a warning in the event of traffic hazards.
Daytime running lights
The car has sensors that detect the light conditions in the surroundings. The daytime running lights are switched on when the rotating ring on the stalk switch is in position , or as well as when the car's electrical system is in ignition position II. In position , the headlamps change automatically to dipped beam in weak daylight or darkness.
Checking trailer lamps
When connecting a trailer - check that all the trailer lamps work before departure.
