Operation Manual

the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R
the distribution of forces during the collision
R
the collision angle
R
the deformation characteristics of the vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-
sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the control unit of the restraint system
dete
cts
a side impact or a vehicle rollover, the relevant
components of the restraint system are activa-
ted separately depending on the anticipated
type of accident.
R
Side impact air bags and pelvis air bag on the
side the impact takes place, independently of
the Emergency Tensioning Device and the use
of the seat belt on the driver's seat and outer
seats in the second row
-
the OCS system detects that the front-
passenger seat is occupied or
-
the belt tongue is engaged in the belt
buckle of the front-passenger seat
R
Window curtain air bag on the side of impact,
independently of the use of the seat belt and
independently of whether the front-
passenger seat is occupied
R
Emergency Tensioning Devices, if the system
determines that deployment can offer addi-
tional protection in this situation
R
Window curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the seat
belt
i
Not all air bags are deployed in an accident.
The different air bag systems work independ-
ently o
f each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
R
Frontal collision
R
Side impact
R
Rollover

Important safety notes
G
WARNING
The function of the head restraint may be
impaired if you:
R
attach objects such as coat hangers to the
head restraints, for example
R
use head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head
restraints and do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraints/NECK-PRO luxury
head restraints offer additional protection
against head and neck injuries. In the event of a
rear collision of a certain severity, the NECK-
PRO head restraints/NECK-PRO luxury head
restraints on the driver's and front-passenger
seats are moved forwards and upwards. This
provides better head support.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in an
accident, reset the NECK-PRO head restraints/
NECK-PRO luxury head restraints on the driver's
