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
situation and be ready to brake.
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
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
X To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (
Y page 274).
When the distance warning function is
activated, the multifunction display shows
the Ä symbol, as long as the HOLD
function is not switched on (
Y page 207). On
vehicles with Active Parking Assist, the
Ä symbol is displayed when position
P is
engaged or you are driving faster than
22 mph (35 km/h).
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. The distance warning function
cannot prevent a collision without your
intervention.
Starting at a speed of around 20 mph
(30 km/h), the distance warning function
warns you if you approach a vehicle in front
very quickly. An intermittent warning tone will
then sound and the · distance warning
lamp will light up in the instrument cluster.
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.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (
Y page 274).
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display unnecessary warnings.
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 extended period of time.
At speeds up to 40 mph (70 km/h), the
distance warning function may also detect
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.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflections,
for example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
i USA only: This device has been approved
by the FCC as a "Vehicular Radar System".
