Foot brake - emergency brake lights and automatic hazard warning flashers
Emergency brake lights are activated in order 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.
Emergency brake lights are activated at speeds above 50 km/h in the event of heavy braking. After the car's speed has been slowed down to below 10 km/h the brake light returns from flashing to the normal constant glow - while at the same time the car's hazard warning lights are activated. These flash until the driver accelerates the car up to a higher speed again or switches off the hazard warning lights.
