Occupant safety
PRE-SAFE ® Sound: provided that the multi‐
R
media system is switched on, generates a
brief noise signal to stimulate the innate pro‐
tective mechanism of a person's hearing.
* NOTE Damage caused by objects in the
footwell or behind the seat
The automatic adjustment of the seat posi‐
tion may result in damage to the seat and/or
the object.
Stow objects in a suitable place.

®
Reversing the PRE-SAFE system measures
If an accident did not occur, the pre-emptive
measures that were taken are reversed.
You will need to perform certain settings your‐
self.
If the seat belt pre-tensioning is not reduced,
#
move the seat backrest back slightly.
The locking mechanism releases.

Function of PRE-SAFE PLUS (anticipatory
occupant protection plus)
®
PRE-SAFE PLUS can detect certain impacts,
particularly an imminent rear impact, and take
pre-emptive measures to protect the vehicle
occupants. These measures cannot necessarily
prevent 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
R
is stationary. This brake application is cancel‐
led 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:
when reversing
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 braking applica‐
tion in the following situations:
whilst driving
R
or
when entering or exiting a parking space
R
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 centre of the vehicle. It does this by
rapidly inflating an air cushion in the outer seat
side bolster of the seat backrest on the side on
which the impact is anticipated. This increases
