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.
The emergency brake lights are activated dur-
ing heavy braking or if the ABS system is acti-
vated at high speeds.
After the driver brakes to a low speed and
then releases the brake, the brake light returns
to normal glow.
The car's hazard warning flashers are acti-
vated at the same time. These flash until the
driver accelerates the car to a higher speed
again or switches off the car's hazard warning
flashers.

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.
Button for hazard warning flashers.
Press the button to activate the hazard warn-
ing flashers.
The hazard warning flashers are automatically
activated when the car brakes so powerfully
that the emergency brake lights are activated
and the speed is low. The hazard warning
flashers start to flash after the emergency
brake lights have stopped flashing and are
then deactivated automatically when the car
drives away again or are deactivated if the but-
ton is depressed.
NOTE
Regulations for the use of hazard warning
flashers may vary between countries.
