Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the two sys‐
tems:
▷Front-end collision warning with City Brak‐
ing function, refer to page 113.▷Front-end collision warning with braking
function, refer to page 116
Front-end collision warning
with City Braking function
The concept The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range
It responds to objects if they are detected by
the system.
Information WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem limits, warnings or reactions of the system
may not be output or they may be output too
late or incorrectly. There is risk of an accident.
Adjust the driving style to the traffic condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g. approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀
