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.
Increasing brake pressure when the vehicle is
R
stationary. This brake application will be can-
celed automatically when the vehicle pulls
away.
If an accident did not occur, the pre-emptive
measures that were taken will be reversed.
System limits
The system will not initiate any action in the fol-
lowing situations:
when the vehicle is backing up
R
or
when the vehicle is towing a trailer and there
R
is a risk of a rear impact
The system will not initiate any brake application
in the following situations:
while you are driving
R
or
when you are entering or exiting a parking
R
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 towards
the center 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, a display message reading PRE-SAFE
Pulse Side Inoperative See Operator's Man-
ual( page 402)will appear.
