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:
R
Tightening the seat belts on the driver's seat
and front passenger seat.
R
Increasing brake pressure when the vehicle is
stationary. This brake application is canceled
automatically when the vehicle pulls away.
If an accident did not occur, the pre-emptive
measures that were taken are reversed.
System limits
The system will not initiate any action in the fol-
lowing situations:
R
if the vehicle is backing up
The system will not initiate any braking application
in the following situations:
R
while driving
or
R
when entering or exiting a parking space while
using Active Parking Assist
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 toward
the center of the vehicle. It does this by rapidly
inating 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 Pulse Side Inoperative
