Occupant safety
57
Your vehicle takes preventive measures to
better protect the occupants in the following
hazardous situations automatically.
PRE-SAFE
®
takes preventive measures in
R
emergency braking situations, e.g. if the
Brake Assist System (BAS) (Y page 66) is
activated
or when
BAS Plus (Y page 66) or the PRE-SAFE
Brake (Y page 72) is strongly intervening
R
critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded its
physical limitations or in case of evasive
steering maneuvers at speeds above
approximately 85 mph (140 km/h)
When you are driving faster than 20 mph
(30 km/h), PRE-SAFE
®
takes the following
measures in such situations:
R
If the passenger seat is in an unfavorable
position, it will be adjusted to a better
position.
R
The system increases the air pressure in
the air pockets (on the sides of the seat
cushion and backrest) of the drive-dynamic
multicontour front seats.
R
If the vehicle is in a critical dynamic driving
situation, the front side windows and the
tilt/sliding sunroof also closes until only a
small gap remains.
If the closing procedure of the side windows
or tilt/sliding sunroof is blocked, the side
windows or tilt/sliding sunroof will stop and
open slightly.
Once the hazardous situation is over without
an accident occurring, PRE-SAFE
®
decreases
the air pressure in the air pockets of the drive-
dynamic multicontour front seats. You can
readjust all of the settings made by PRE-
SAFE
®
.
If the seat belts do not release:
X
Adjust the seat backrest to the rear until
the seat belt tension is diminished.
The locking mechanism releases.
!
When adjusting the seat backrests, make
sure there are no items behind the seats.
Otherwise, you could damage the seats.
Correct driver seat adjustment
G
Warning!
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel, and rear view mirror adjustments, as
well as fastening of seat belts, must be
done before the vehicle is put into motion.
