Example: side impact ai
rbag on the driver's side
Side impac tair bags 0003deploy nex tto the
outer side bolsters of the seat backrest.
When deployed, the side impact air bags offer
additional protection for the thorax of the
vehicle occupants on the side of the vehicle
on which the impact occurs. However, they
do not protect the:
R head
R neck
R arms
The side impact air bags are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in aside impact
R depending on whether the seat belt is being
used
R independently of the front air bags
R independently of the ETDs
If the vehicle overturns, the side impac tair
bags are generally not deployed. Side impact
air bags are deployed if the system detects
high vehicle deceleration or acceleration in a
lateral direction and determines that side
impac tair bag deploymen tcan offer
additional protection to that provided by the
seat belt.
Side impac tair bags will not deploy in side
impacts which do not exceed the system's
prese tdeployment thresholds for lateral
acceleration/deceleration .You will then be
protected by the fastened seat belt. The side impact air bag on the front-
passenger side does not deploy under the
following conditions:
R
the OCS system detects that the front-
passenger seat is not occupied, and
R the front-passenger seat belt is not
fastened.
The side impact air bag on the front-
passenger side will deploy if the front-
passenger seat belt is fastened, regardless of
whether the front-passenger seat is occupied
or not.
Head bags Example: headbag on the front-passenger side
Headbags
0003deploy in the area of the side
windows at the front.H eadbags enhance the
level of protection for the head, but not chest
or arms, of the vehicle occupants on the side
of the vehicle on which the impact occurs.
The headbags are deployed:
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in aside impact
R on the side on which an impac toccurs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that ai rbag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the use of the seat belt
R independently of the fron tair bags
Headbags will not deploy in side impacts
which do not exceed the system's preset 44

PRE-SAFE
®
(preventative occupant
protection)
i AMG vehicles do not include the PRE-
SAFE ®
system.
All vehicles (except AMG vehicles): the
PRE-SAFE ®
system is only available in
vehicles with DISTRONIC PLUS. G
WARNING
Make sure that nobody can become trapped
as you adjust the seat. G
WARNING
The PRE-SAFE ®
system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R if BAS intervenes, e.g. in emergency
braking situations.
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS.
R when the radar sensor system detects an
imminent danger of collision in certain
situations on vehicles with DISTRONIC
PLUS.
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely. PRE-SAFE
®
takes the following measures
depending on the hazardous situation
detected:
R the seat belts are pre-tensioned.
R on vehicles with memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
R if the vehicle skids, the side windows are
closed almost completely.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.

Important safety notes G
WARNING
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags are deployed, or they can
prevent this completely. The NECK-PRO head
restraints or side impact air bags can
therefore not provide the intended protection.
Do not use any seat or head restraint covers. 50
