COLLISION PREVENTION ASSIST General notes
COLLISION PREVENTION ASSIST comprises
the distance warning function and adaptive
Brake Assist.
Distance warning function
Important safety notes
i Note the section on 'Important safety
notes' ( Ypage 56). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
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:
R give an unnecessary warning
R not give a warning
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. Operation
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 func-
tion detects that there is a risk of a collision,
you will be warned visually and acoustically.
Without your intervention, the distance warn-
ing function cannot prevent a collision.
The distance warning function will issue a
warning at speeds of around 20 mph
(30 km/h) or more if:
R
you approach a vehicle ahead of you very
quickly. You will then hear an intermittent
warning tone and the 00C7warning lamp in
the instrument cluster flashes.
X Brake immediately in order to increase the
distance from the vehicle in front.
Or
X Take evasive action provided it is safe to do
so.
If you want the distance warning function to
assist you, the function must be activated and
operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary 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.
From a speed of around 45 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 alert you both visually and
acoustically.
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or anything else cover-
ing the sensors
R it is snowing or raining heavily 58
