■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as thefront seats, parts of the front and rear pillars , and roof side rails, may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force corresponding to an approximately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be cons iderably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possib le that only the seat belt pretensioners will
activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact force produced by an approximately 1500 kg [3300 lb.] vehicle colliding with the vehiclecabin from a direction perpendicular to the vehicle orientation at an approximate
sp ee d o f 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags will de ploy in the event of a severe frontal colli- sion.

■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain sh ield airbags may also deploy if a serious impact occurs to the underside of your vehi cle. Some examples are shown in the illustra-
tion.
■Types of collisions that may not depl oy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forward deceleration of the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumpin g over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

■Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to a
collision from the side at certain angles, or a co llision to the side of the vehicle body other than the passenger compartment.
The SRS side and curtain shield airbags do not generally inflate if the vehicle is involved in a rear collision, if it rolls over, or if it is involved in a low-speed side or low-speed frontal
collision.
●Collision from the side to the vehicle body other than the passenger compartment
●Collision from the side at an angle
●Collision from the rear
●Vehicle rollover

WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint system in a rear seat. In the event that the rear seat cannot be used, the front seat can be used as long as the airbag manualon-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to “ON”. If it is left off, the airbag may not deploy in the event of an accident, which may result inserious injury or even death.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object

WARNING
■When installing a child restraint system
Observe the following when in stalling child restraint system to the front passenger seat if it is unavoidable. The front passenger SRS airbag inflates with considerable speed
and force that if not observed may lead to death or serious injury to the child.
●Never use a rear-facing child restraint system
on the front passenger seat when the airbag manual on-off switch is on. ( P. 54) The force of the rapid inflation of the front
passenger airbag can cause death or serious injury to children in the event of an accident.
●There is a label(s) on the passenger side sunvisor, indicating it is forbidden to attach arear-facing child restraint system to the front
passenger seat. Details of the label(s) are shown in theillustration below.
