Foot brake - anti-lock braking system

The anti-lock braking system, ABS (Anti-lock
Braking System), prevents the wheels from
locking up during braking.
The function allows steering ability to be
maintained, and it is easier to swerve to avoid
a hazard for example. Vibration may be felt in
the brake pedal when this is engaged and this
is normal.
A short test of the ABS system is made auto-
matically after the engine has been started
when the driver releases the brake pedal. A
further automatic test of the ABS system may
be made when the car reaches 10 km/h. The
test may be experienced as pulses in the
brake pedal.

08 Starting and driving
Foot brake - emergency brake lights
and automatic hazard warning
flashers
Emergency brake lights are activated to alert
vehicles behind about sudden 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 if the ABS system is
working and/or in the event of sudden brak-
ing. After the car's speed has been slowed
below 10 km/h the brake light returns from
flashing to the normal constant glow - while
at the same time the Hazard warning flashers
are activated, and they flash until the driver
accelerates the car to at least 20 km/h or they
are deactivated with their button.
