If you change wheel size, make sure they corre-
spond to the correct wheel size category
(
Y
page 268). If the category is changed without
recoding the control units in the vehicle, the
functioning of the distance warning feature may
be impaired. COLLISION PREVENTION ASSIST
may then detect a malfunction and switch itself
off.
Operation
X
To activate/deactivate: activate or deacti-
vate the distance warning function in the on-
board computer (
Y
page 185).
If the distance warning function of the COL-
LISION PREVENTION ASSIST is activated, the
display shows the Ä symbol:
R

menu (

At speeds up to approx 20 mph (30 km/h) the
display in vehicles with Active Parking Assist
first shows the í status indicator. Only from
a speed of about 20 mph (30 km/h) does the
display show the Ä symbol instead of the
í status indicator.
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. With the help of the radar sensor sys-
tem, the distance warning function can detect
obstacles that are in the path of your vehicle for
an extended period of time. If the distance warn-
ing function detects that there is a risk of a col-
lision, you will be warned visually and, where
necessary, acoustically. Without your interven-
tion, the distance warning function cannot pre-
vent a collision.
The distance warning function issues a warning
at speeds:
R
from about 4 mph (7 km/h) if you approach a
vehicle traveling in front or a stationary vehi-
cle very quickly. The · warning lamp in the
instrument cluster flashes and an intermittent
warning tone also sounds.
At speeds up to about 45 mph (70 km/h), the
system also detects stationary obstacles, for
example stationary or parked vehicles.
X
Brake immediately until the distance to the
obstacle increases and the risk of a collision
has passed.
or
X
Take evasive action, provided it is safe to do
so.
Adaptive Brake Assist
General notes
Adaptive Brake Assist evaluates the traffic sit-
uation with the help of the radar sensor system
and can detect obstacles which have been in
your vehicle's path for an extended period of
time. From speeds above 4 mph (7 km/h), Adap-
tive Brake Assist aids you in braking during haz-
ardous situations.
Up to a speed of approximately 125 mph
(200 km/h), Adaptive Brake Assist is capable of
reacting to moving obstacles that have already
been detected as such at least once over the
period of observation.
Important safety notes
G
WARNING
Adaptive Brake Assist does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
R
intervene unnecessarily
R
not intervene
There is a risk of an accident.
