Brake lights
The brake light automatically comes on dur-
ing braking.
The brake light is illuminated when the brake
pedal is depressed and when the car is braked
automatically by one of the driver support sys-
tems.
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.
The rear fog lamp is switched off automatically
when:
the car is switched off or when the rotat-
ing ring on the stalk switch is set to the

LIGHTING
Emergency brake lights
Emergency brake lights are activated to alert
vehicles behind about heavy braking.
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.
Regulations for the use of hazard warning
flashers may vary between countries.
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.

The hazard warning flashers are automatically
activated when the car brakes so powerfully
that the emergency brake lights are activated

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.
