EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.GWarning!
If the EBD malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
Distance warning function (vehicles
with DISTRONIC)
This function warns you from a speed of
approximately 20 mph (30 km/h), if:
R for a period of several seconds, the
distance to the vehicle in front is too short
for the speed at which you are traveling.
The · distance warning lamp in the
instrument cluster will light up.
R you are approaching the vehicle in front
rapidly. An intermittent warning tone will
then sound and the · distance warning
lamp in the instrument cluster will light up.
You must apply the brakes yourself in order
to maintain the appropriate distance to the
vehicle in front and prevent a collision.
GWarning!
If the distance warning lamp · in the
instrument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the driver
is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do not
drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always
fully recognized by the distance warning
function. This could result in wrong or missing
distance warnings.XTo activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer ( Y page 226).
After activation, the Ä symbol is
displayed in the lower multifunction
display.
