Safety and Security
Occupant safety
Preventive occupant safety (PRE-SAFE)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:
ț You execute an emergency braking ma-
neuver and the Brake Assist System
(
୴ page 78) is activated.
ț The PRE-SAFE system detects a critical
driving dynamics situation.
In such cases, the following systems are
automatically activated:
ț A front seat belt with the seat belt
buckled is pre-tensioned electrically.
ț If the occupied front passenger seat or
rear seats are in an unfavorable posi-
tion, they are adjusted to a better posi-
tion. Rear seat adjustment occurs only
in vehicles with individual seats* in the
rear.
ț The sliding/pop-up roof closes if the
vehicle is in a severe skid or is spin-
ning.
If the seat belts do not release:
̈ Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning
G
The PRE-SAFE system is intended to reduce
the effects of an accident on properly seat
belted vehicle occupants. Despite having
the PRE-SAFE systems in your car, the pos-
sibility of injuries occurring as a result of an
accident cannot be totally eliminated.
Therefore you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
i
The PRE-SAFE systems are activated in
the previously described circumstanc-
es only at speeds exceeding 22 mph
(35 km/h).
When the driving dynamic situation has
passed without an accident occurring,
the pre-tensioning on the seat belts is
deactivated.
You can then adjust the seats and the
sliding sunroof to their previous posi-
tion.
