Window curtain air bag
When deployed, the window curtain air bags
are designed to provide increased protection
for the head (but not the chest or arms) of the
occupants on the side of the vehicle on which
the impact occurs.
The window curtain air bags are deployed:
R
on the impacted side of the vehicle
R
in side impacts exceeding a preset deploy-
ment threshold
R
independently of the front air bags
R
regardless of whether the front passenger
seat is occupied
R
in certain vehicle rollovers, if the system
determines that air bag deployment can
offer additional protection to that provided
by the seat belt
The window curtain air bags are not deployed
in impacts which do not exceed the system’s
deployment threshold.
The window curtain air bags deploy in 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 classified occu-
pant weight category determined by weight
sensor readings from the front passenger
seat.
The system does not deactivate the front pas-
senger side impact air bag, the window cur-
tain air bag and the Emergency Tensioning
Devices (ETDs).
Occupants must sit with the seat belt prop-
erly fastened in a position 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 trans-
ferred to another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the occupant’s
weight category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between the
seat and middle console or the seat and door,
other passengers pushing on the seat, or
objects applying pressure to the back of the
seat. Always make sure the seat has clear-
ance in all directions at all times.
