301-1. For safe use
based on US motor vehicle safety standards (FMVSS208). The air-
bag sensor assembly (ECU) controls airbag deployment based on
information obtained from the sensors, etc., shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed of deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the parts
around the airbags may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●All of the doors will be unlocked.
( P.105)
●The brakes and st op lights will be
controlled automatically. ( P.275)
●The interior lights will turn on auto-
matically. ( P.303)
●The emergency flashers will turn
on automatically. ( P.382)
●Fuel supply to the engine will be
stopped. (P.390)
●For Safety Connect subscribers, if
any of the followin g situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call as an emergency and helps to dis-
patch the necessary emergency
services. (

• When an SRS airbag has been
deployed
• When a seat belt pretensioner has operated
• When the vehicle has been involved in a severe rear-end colli-
sion
■The SRS airbags deploy in a
frontal impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds a th reshold level
(level of force corresponding to an
approximately 12 - 18 mph [20 -
30 km/h] frontal collision with a
fixed wall that does not move or
deform):
• SRS front airbags
• SRS knee airbag
●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle “underrides”, or goes under,
the bed of a truck
●Depending on the type of collision,
only the following may deploy:
• Seat belt pretensioners
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passe nger in the front
passenger seat. However, the

Driving
●If the orientation of a sensor has
been changed due to a collision or
other impact
●The vehicle is approaching a tall
or curved curb
●Driving close to columns
(H-shaped steel beams, etc.) in
multi-story parking garages, con-
struction sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning
●On an extremely bumpy road, on
an incline, on gravel, or on grass
●When a tire chains or compact
spare tire is used
■Detection range of the sen-
sors
Approximately 3.3 ft. (100
cm)
Approximately 4.9 ft. (150
cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
