G Warning!
Pyrotechnic ETDs that were activated must
be replaced.
For your safety, when disposing of the

authorized Mercedes-Benz Center.
PRE-SAFE
® has electrically operated
reversible pre-tensioners that do not
require replacement after activation.
Preventive occupant safety (PRE-
SAFE
® )
G Warning!
PRE-SAFE ® is intended to reduce the
effects of an accident on vehicle occupants
who are wearing their seat belt properly.
Despite having the PRE-SAFE
® system in
your vehicle, 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 takes preventive measures to
better protect the occupants in the following
hazardous situations automatically.
PRE-SAFE
® takes action in
R emergency braking maneuvers with the
Brake Assist System (BAS) (
Y page 77)
activated
R critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded its
physical limitations
When you are driving faster than 22 mph
(35 km/h), PRE-SAFE
® takes the following
measures in such situations:
R The front seat belts are pre-tensioned
automatically.
R Vehicles with front passenger seat memory
function: If the passenger seat is in an
unfavorable position, it will be adjusted to
a better position.
R If the vehicle is in a severe skid or is
spinning, the door windows close until only
a small gap remains.
R Vehicles with power tilt/sliding sunroof: If
the vehicle is in a severe skid or is spinning,
the tilt/sliding sunroof also close until only
a small gap remains.
If the closing procedure of the door windows
or tilt/sliding sunroof is blocked, the door
windows or tilt/sliding sunroof will stop and
open slightly.
Once the hazardous situation is over without
an accident occurring, the seat belt pre-
tensioning is deactivated. You can readjust all
of the settings made by PRE-SAFE
® .
If the seat belts do not release:
X Adjust the seat backrest or seat slightly to
the rear until the seat belt tension is
diminished.
The locking mechanism releases.
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats.
