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 ®

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

The sy stem will not initiate any action in thefo l‐
lowing situations:
R when reve rsing

SAFE®
Impulse Side If an imminent side impact is de

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.
