Function of PRE-SAFE PLUS (anticipatory
occupant protection plus)
PRE-SAFE ® PLUS can detect certain impacts,
particularly an imminent rear impact, and take
pre-emptive measures to protect the vehicle
occupants. These measures cannot necessarily
prevent an imminent impact.
PRE-SAFE ® PLUS can implement the following
measures independently of each other:
Tightening the seat belts on the driver's seat
R
and front passenger seat.
Activating the rear hazard warning lights at a
R
higher flashing frequency.
Increasing brake pressure when the vehicle
R
is stationary. This brake application is cancel‐
led automatically when the vehicle pulls
away.
If an accident did not occur, the pre-emptive
measures that were taken are reversed.
System limitations
The system will not initiate any action in the fol‐
lowing situations:
when reversing
R
or
when the vehicle is towing a trailer and there
R
is a risk of a rear impact
Occupant safety
The system will not initiate any braking applica‐
tion in the following situations:
whilst driving
R
or
when entering or exiting a parking space
R
while using Active Parking Assist
Information on PRE-SAFE ® Impulse Side
If an imminent side impact is detected, PRE-
SAFE ® Impulse Side can pre-emptively move the
front seat vehicle occupant's upper body
towards the centre of the vehicle. It does this by
rapidly inflating an air cushion in the outer seat
side bolster of the seat backrest on the side on
which the impact is anticipated. This increases
the distance between the door and the vehicle
occupant.
If PRE-SAFE ® Impulse Side has been deployed or
is faulty, the PRE-SAFE impulse side inoperative
