Speed range
The basic function of the proactive occupant
protection system is available when driving
forwards at speeds from approx. 30 km/h
(19 mph).
Displays
In the event of intervention by the
proactive occupant protection sys-
tem, the red warning lamp lights up
on the instrument cluster display.
WARNING
The intelligent proactive occupant protec-
tion system cannot overcome the laws of
physics, and functions only within the lim-
its of the system. Never let the extra con-
venience afforded by the proactive occu-
pant protection system tempt you into tak-
ing any risks when driving. The system can-
not prevent a collision. The system is not
a substitute for the full concentration of
the driver.
·
Adapt your speed and distance from the
vehicles ahead to suit visibility, weather,
road and traffic conditions.
·
The system cannot detect objects in all
situations.
·
The proactive occupant protection sys-
tem does not react to animals or poorly
visible objects.
·
Reflective objects such as safety barri-
ers, tunnel entrances, heavy rain and ice
can impair the performance of the pro-
active occupant protection system and
thus prevent it from detecting a collision
risk.
·
The system may be falsely triggered.
Functions of the proactive oc-
cupant protection system
Please refer to at the start of the chap-
Basic functions
The following functions may be triggered in-
dividually or together in critical driving situa-
tions, e.g. in the event of emergency braking,
understeer and oversteer or minor collisions:
— Reversible belt tensioning of the fastened
driver and front passenger seat belts.
— Depending on the vehicle equipment, au-
tomatic closing of the side windows down
to a small gap.
— Activation of the hazard warning lights.
The belts may be tensioned individually or to-
gether depending on the respective critical
driving situations.
Additional functions for vehicles with Auton-
omous Emergency Braking (Front Assist)
For vehicles with Autonomous Emergency
Braking (Front Assist), the system limits also
include calculation of the probability of
a rear-end collision with the vehicle in front.
If the system detects that a rear-end collision
is likely, or initiates severe braking, it can
trigger the proactive occupant protection
system.
Additional functions for vehicles with Emer-
gency Assist
The proactive occupant protection system
may be triggered in vehicles with Emergency
Assist if no driver activity is detected.
Depending on the activation level, the fol-
lowing functions are triggered:
— Reversible belt tensioning of the driver's
fastened seat belt for a brief or extended
period of time.
— Depending on the vehicle equipment, au-
tomatic closing of the side windows down
to a small gap.
