Warning!
®
The PRE-SAFE
system is intended to re-
duce the effects of an accident on properly
seat-belted vehicle occupants. Despite
®
having the PRE-SAFE
system in your vehi-
cle, the possibility of injuries occurring as a
result of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations.

PRE-SAFE
takes action in the following in-
stances:
Emergency braking situations, e.g.
G
when BAS ( page 71) is activated or
when
BAS Plus* ( page 71) is strongly inter-
vening.
Critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded
its physical limitations.
Evasive steering maneuvers at speeds
above 19 mph (30 km/h).
When you are driving faster than 19 mph
(30 km/h), PRE-SAFE
measures in such situations:
The front seat belts are pre-tensioned
electrically.
If the OCS senses that the front pas-
senger seat is occupied and the seat is
in an unfavorable position, it will be
adjusted to a better position.
If the vehicle is equipped with power
adjustable rear seats* and the passen-
ger outer seats are in an unfavorable
position, they will be adjusted to a bet-
ter position.
It increases the air pressure in the air
pockets (on the sides of the seat cush-
ion and backrest) of the multicontour*
and/or drive-dynamic front seats*.
If the vehicle is understeering or over-
steering, the tilt/sliding sunroof and
the side windows also close until only a
small gap remains.
Once the hazardous situation is over with-
out an accident occurring, PRE-SAFE
®
takes the following
loosens the belt pre-tension and decreas-
es the air pressure in the air pockets of the
multicontour and drive-dynamic seats*.
You can readjust all of the settings made
by PRE-SAFE
i
If the closing procedure of the tilt/sliding
sunroof or door windows is blocked, the tilt/slid-
ing sunroof or door windows will stop and open
