Before driving
PRIUS_U_(OM47614U)
Your vehicle is equipped with “ADVANCED AIRBAGS” designed
based on US motor vehicle safety standards (FMVSS208). The air-
bag system controls air
bag deployment power for the driver and front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants.
■ If the SRS airbags deploy (inflate)
● Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the seats, and parts of the front and rear pillars and roof side
rail, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.

smaller adult sits in the front passenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2:In the event the front passenger does not wear a seat belt.
*3:When a large child who has outgro wn a child restraint system sits
in the front passenger seat, the system may recognize him/her as
an adult depending on his/her physique or posture.

■
Front passenger occupant cl assification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt tab has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator lights is not illuminated when
using the seat belt extender for the front passenger seat. If the “AIR BAG
OFF” indicator light is illuminated, disconnect the extender tongue from
the seat belt buckle, then reconnect the seat belt. Reconnect the seat belt
extender after making sure the “AIR BAG ON” indicator light is illuminated.
If you use the seat belt extender while the “AIR BAG OFF” indicator light is
illuminated, the front passenger airbag and side airbag on the front pas-
senger side may not activate correctly, which could cause death or serious
injury in the event of collision.
● Do not apply a heavy load to the front passenger seat.
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.
● Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the passenger’s airbags will not deploy in the event of
a severe accident. If the seatback touches the rear seat, return the seat-
back to a position where it does not touch the rear seat. Keep the front
passenger seatback as upright as possible when the vehicle is moving.
Reclining the seatback excessively may lessen the effectiveness of the
seat belt system.

CAUTION
■Front passenger occupant cl assification system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator light is illuminated, ask
the passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the “AIR BAG OFF” indicator light still
remain illuminated, either ask the passenger to move to the rear seat, or if
that is not possible, move the front passenger seat fully rearward.
● When it is unavoidable to install the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( P. 1 1 1 )
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction on the
detection system. In this case, contact your Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion or seat cover, that covers
the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.
