Safety and Security
Occupant safety
The side impact air bags are deployed:
앫
in side impacts exceeding a preset de-
ployment threshold
앫
on the impacted side of the vehicle
앫
independently of the front air bags
The front passenger side impact air bag
1
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy regardless
of the empty seat.
The side impact air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
Window curtain air bags

Window curtain air bag
The side window curtain air bags are de-
ployed:
앫
in side impacts exceeding a preset de-
ployment threshold
앫
on the impacted side of the vehicle
앫
independently of the front air bags
앫
in certain vehicle rollovers
The side window curtain air bags are not
deployed in side impacts which do not ex-
ceed the system’s deployment threshold.
The window curtain air bags fill up the area
indicated by the arrows.
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category.
i
The system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the emergency tensioning de-
vice.
