uuAirbags uFront Airbags (SRS)
Safe Driving
The front passenger’s ad vanced airbag system
has weight sensors. The sensors are used for
occupant classification to activate or
deactivate the front passenger’s airbag.
For adult size occupant s, the system will
automatically activate the front passenger’s
airbag. If a small adult sits in the front
passenger seat and the system does not
recognize him/her as an adult, see
2 Passenger Front Airbag Off Indicator P. 61
We advise against allowing a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a small child or
infant to ride in the front passenger’s seat, the
system is designed to automatically deactivate
the front passenger’s airbag. Do not let a
small child or infant ride in the front
passenger’s seat if the airbag does not
automatically deactivate.
1 Advanced Airbags
For the advanced front airbags to work properly,
confirm that:
•The occupant is sitting in an upright position,
wearing the seat belt prope rly and the seat back is
not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are plac ed on the floor in front
of them.
•There are no objects ha nging from the front
passenger’s seat.
•Only small, lightweight objec ts are in the seat back
pocket.
•The steering wheel and passenger’s side dashboard
are not obstructed by any object.
•No liquid has been spille d on or under the seat.•There is no child seat or other object pressing
against the rear of the seat or seat back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.
•There are no objects placed under or beside the
front passenger’s seat . Improperly positioned
objects can interfere with the advanced airbag
sensors.
•The head restraint is not contacting the roof.

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 this 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
1 Side 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.
