brake the vehicle
R
neither give a warning nor intervene
There is a risk of an accident.

situation and be ready to brake, especially if

ing the sensors

R
interference by other radar sources
R
the possibility of strong radar reflections,
for example, in multi-storey car parks

line
G WARNING

As a result, PRE-SAFE ® Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.

page 272)
Vehicles with COMAND and a navigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (

system and vehicles for Australia: the radar
sensor system and on-board computer must

scope facilities (

Following damage to the front end of the vehi-

the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
