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 the front 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.

●

For U.S.A.: For Safety Connect subscribers, if the SRS airbags deploy or in
the event of a severe rear-end collision, the system is designed to send an
emergency call to the response center, notifying them of the vehicle's loca-
tion (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 auto-
matically treats the call as an emergency and helps to dispatch the
necessary emergency services. (

→P. 490)

■

SRS airbag deployment conditions (SRS front airbags)

●

The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the 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).

However, this threshold velocity will be considerably 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 possible that only the seat belt pre-
tensioners will activate.

●

The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied. (

→P. 53)

●

The SRS seat cushion airbag on the front passenger’s seat will not operate
if the occupant is not wearing a seat belt.

SRS airbag deployment conditions (SRS side and curtain shield airbags)

●

The SRS side and curtain shield airbags will 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 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).

●

The SRS curtain shield airbags will deploy in the event of vehicle rollover.

●

The SRS side and curtain shield airbags will deploy in the event of a severe
frontal collision.

■

Conditions under which the SRS airbags may deploy (inflate), other than
a collision 
The SRS front airbags and SRS side and curtain shield airbags may also
deploy if a serious impact occurs to the underside of your vehicle. Some
examples are shown in the illustration.

The SRS curtain shield airbags may also deploy under the situations shown
in the illustration.

●

Hitting a curb, edge of pavement or hard
surface

●

Falling into or jumping over a deep hole

●

Landing hard or falling

●

The angle of vehicle tip-up is marginal

●

The vehicle skids and hits a curb stone

■

Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
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.

■

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 collision to the
side of the vehicle body other than the passenger compartment.

The SRS side 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

●

Collision from the rear

●

Vehicle rollover

●

Collision from the side to the vehicle
body other than the passenger compart-
ment

●

Collision from the side at an angle

●

Collision from the rear

●

Vehicle rollover

The SRS curtain shield airbags do not generally inflate if the vehicle is
involved in a rear collision, if it pitches end over end, or if it is involved in a
low-speed side or low-speed frontal collision.

■

When to contact your Toyota dealer
In the following cases, the vehicle will require inspection and/or repair. Con-
tact your Toyota dealer as soon as possible. 

●

Any of the SRS airbags have been inflated.

●

Collision from the rear

●

Pitching end over end

●

The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS front airbags to inflate.

●

A portion of a door or its surrounding
area is damaged or deformed, or the
vehicle was involved in an accident that
was not severe enough to cause the
SRS side and curtain shield airbags to
inflate.
