Distance warning function

Important safety notes

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.
G 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 and do not rely solely on the distance
warning function.
Function
To activate/deactivate: activate or deac-
X
tivate the distance warning function in the
on-board computer (
If the distance warning function is not activa-
ted, the æ symbol appears in the assis-
tance graphics display.
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.

Starting at a speed of around 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-
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 around 44 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
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.
The autonomous braking function:
gives the driver more time to react to criti-
R
cal driving situations
can help the driver to avoid an accident or
R
reduces the effects of an accident
R
The autonomous braking function is available
in the following speed ranges:
from 5 mph (7 km/h) to approx. 65 mph
R
(105 km/h) for moving objects
from 5 mph (7 km/h) to approx. 31 mph
R
(50 km/h) for stationary objects
