Function of PRE-SAFE PLUS (anticipatory occu-
pant protection plus)
®
PRE-SAFE PLUS can detect certain impacts, par-
ticularly an imminent rear impact, and take pre-
emptive measures to protect the vehicle occu-
pants. These measures cannot necessarily pre-
vent 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 is
R
stationary. This brake application is cancelled
automatically when the vehicle pulls away.
If an accident did not occur, the pre-emptive
measures that were taken are reversed.
System limits

lowing situations:

Function of 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 bol-
ster 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
