versing the PRE- SAFE®
sy stem measures If an accident did not occur,
the pre-em ptive
measures that we retak en are reve rsed.

The locking mechanism releases. Fu
nction of PRE-SAFE ®
PLUS (anticipatory
occupant pr otection plus) PRE-
SAFE®
PLUS can de tect cer tain impacts,
particular lyan imminent rear impact, and take
pre-em ptive measures toprotect theve hicle
occupants. These measures cannot necessarily
pr eve nt an imminent impact.
PRE-SAFE ®
PLUS can implement thefo llowing
measures independently of each other:
R Tightening the seat belts on the driver's seat
and front passenger seat.
R Activating there ar hazard warning lights at a
higher flashing frequenc y. R
Increasing brake pressure when theve hicle
is stationar y.This brake application is cancel‐
led automatically when theve hicle pulls
aw ay.
If an accident did not occur, the pre-em ptive
measures that we retake n are reve rsed.
Sy stem limitations
The sy stem will not initiate any action in thefo l‐
lowing situations:
R when reve rsing
or
R when theve hicle is towing a trailer and there
is a risk of a rear impact
The sy stem will not initiate any braking applica‐
tion in thefo llowing situations:
R whilst driving
or
R when entering or exiting a parking space
while using Active Parking Assist Information on PRE-
SAFE®
Impulse Side If an imminent side impact is de
tected, PRE-
SA FE®
Impulse Side can pre-emptively mo vethe
front seat vehicle occupant's upper body
to wa rdsth e cent reoftheve hicle. It does this by
ra pidly inflating an air cushion in the outer seat
side bols ter of the seat backrest on the side on
which the impact is anticipated. This increases
th e dis tance between the door and theve hicle
occupant.
If PRE-SAFE ®
Impulse Side has been deplo yed or
