clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:

R
not give a warning
R
There is a risk of an accident.
Always pay careful attention to the traffic

Function
To activate/deactivate: activate or
X
deactivate the distance warning function in
the on-board computer (
If the distance warning function is not
activated, the æ symbol appears in the
assistance 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. The distance warning function
cannot prevent a collision without your
intervention.
Starting at a speed of around 4 mph
(7 km/h), the distance warning function
warns you if you rapidly approach a vehicle in
page 247).
