WARNING
The distance warning function does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.

WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
give an unnecessary warning
R
not give a warning
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function
The distance warning function issues a warning
at speeds:
of approximately 30 km/h or more if, over
R
several seconds, the distance to the vehicle
travelling in front is insufficient for the driving
speed. The · distance warning lamp will
then light up on the instrument cluster.
of approximately 7 km/h or more if you rap-
R
idly approach a vehicle in front. An intermit-
tent warning tone will then sound and the
· distance warning lamp will light up on
the instrument cluster.
Brake immediately to increase the distance

from the vehicle in front.
or
Take evasive action provided it is safe to do
X
so.

Y
Due to the nature of the system, certain com-
plex but non-critical driving conditions may also
cause the system to display a warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function:
gives the driver more time to react to critical
R
driving situations
can help the driver to avoid an accident or
R
reduces the effects of an accident
R
Vehicles without Distance Pilot DISTRONIC:
the autonomous braking function is available in
the following speed ranges:
7 - 105 km/h for moving objects
R
7 - 50 km/h for stationary objects
R
Vehicles with Distance Pilot DISTRONIC: the
autonomous braking function is available in the
following speed ranges:
7 - 200 km/h for moving objects
R
7 - 50 km/h for stationary objects
R
Due to the nature of the system, complex but
non-critical driving conditions may also cause
the autonomous braking function to engage.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
are activated simultaneously (
