Distance warning function

General information
The distance warning function can help you to
minimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (
G WARNING
The distance warning function does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
Thus, the distance warning function cannot
provide a warning 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.
WARNING

The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function

uation and do not rely solely on the distance
warning function.
Function
Starting at a speed of approximately 4 mph
(7 km/h), the distance warning function
warns you if you rapidly approach a vehicle in
front. An intermittent warning tone will then
sound, and the · distance warning lamp
will light up in the instrument cluster.
Brake immediately in order to increase the
X
distance from the vehicle in front.
or
Take evasive action, provided it is safe to do
X
so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-

Y
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of approximately 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as
stopped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, COLLI-
SION PREVENTION ASSIST PLUS can assist
with the autonomous braking function.
