PRE-SAFE (anticipatory occupant
protection system)
Introduction
®
PRE-SAFE takes preemptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes
! Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Despite your vehicle being equipped with the
®
PRE-SAFE system, the possibility of per-
sonal injuries occurring as a result of an acci-
dent cannot be eliminated.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.

NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection for the driver's and front passenger's
head and neck. In the event of a rear collision
of a certain severity, the NECK-PRO head
restraints on the driver's and the front-
passenger seats are moved forwards and
upwards. This provides better head support.
