When deployed, the side impact air bags offer
additional protection for the thorax and, on
the front seats, the pelvis of the vehicle
occupants on the side of the vehicle on which
the impact occurs. However, they do not
protect the:
Rhead
Rneck
Rarms
The side impact air bags are deployed:
Ron the side on which an impact occurs
Rat the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
Rregardless of whether the seat belt on the
driver's seat and the outer seats of the 2nd
row of seats is used
Rindependently of the front air bags
Rindependently of the ETDs
If the vehicle rolls over, the side impact air
bags are generally not deployed. side impact
air bags are deployed if the system detects
high vehicle deceleration or acceleration in a
lateral direction, or also if the vehicle rolls
over, and the system determines that side
impact air bag deployment can offer
additional protection to that provided by the
seat belt.
Side impact air bags will not deploy in side
impacts which do not exceed the system's
preset deployment 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 is not deployed in the
following situations:
Rthe OCS system detects that the front-
passenger seat is not occupied, and
Rthe 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.
Window curtain air bags
Window curtain air bagsCenhance 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 window curtain air bags are integrated
into the side of the roof frame and deploy in
the area extending from the front door (A-
pillar) to the rear side window (D-pillar).
Window curtain air bags are deployed:
Rat the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
Ron the side on which an impact occurs
Ron the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
Rindependently of the use of the seat belt
Rregardless of whether the front-passenger
seat is occupied
Rindependently of the front air bags
Window curtain air bagsCwill not deploy in
the event of impacts which do not exceed the
system's preset deployment thresholds for
vehicle acceleration/deceleration. You will
then be protected by the fastened seat belt.
