However, if you do allow a small child or in fant to ride in the front passenger’s seat,
the system is designed to automatically de activate the front passenger’s airbag. Do
not let a small child or infant ride in the fr ont passenger’s seat if the airbag does not
automatically deactivate.1 Advanced Airbags

uuAirbags uSide Curtain Airbags
Safe Driving
Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and passengers in the
outer seating positions during a moderate-to -severe side impact. The side curtain
airbags equipped in th is vehicle are also designed to help reduce the likelihood of
partial and complete ejection of vehicle occupants through side windows in crashes,
particularly rollover crashes.
The side curtain airbags are located in the
ceiling above the side windows on both sides
of the vehicle.
The side curtain airbag is designed to deploy
in a rollover or a moderate-to-severe side
impact.
■Housing Locations
1Side Curtain Airbags
To get the best protecti on from the side curtain
airbags, occupants should wear their seat belts
properly and sit upr ight and well back in their seats.
Do not attach any objects to the side windows or roof
pillars as they can interfere with the proper operation
of the side curtain airbags.
If the impact is on the passenger’s side, the
passenger’s side curtain airbag deploys even if there
are no occupants on that side of the vehicle.
If the SRS control unit sens es that your vehicle is
about to rollover, it imme diately deploys both side
curtain airbags and activates both front seat belt
tensioners.
