Toyota RAV4 (XA50) 2019-2024 Owners Manual: SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury
to the occupants. They work together with the seat belts to
help reduce the risk of death or serious injury.
SRS airbag system
â– Location of the SRS airbags
SRS front airbags
- SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front passenger from
impact with interior components
- SRS knee airbag
Can help provide driver protection
- SRS seat cushion airbag
Can help restrain the front passenger
SRS side and curtain shield airbags
- SRS side airbags
Can help protect the torso of the front seat occupants
- SRS curtain shield airbags
- Can help protect primarily the head of occupants in the outboard
seats
- Can help prevent the occupants from being thrown from the vehicle in
the
event of vehicle rollover
â– SRS airbag system components
- Front impact sensors
- "AIR BAG ON" and "AIR BAG OFF" indicator lights
- Front passenger airbag
- Side impact sensors (front door)
- Curtain shield airbags
- Seat belt pretensioners and force limiters
- Side impact sensors (front)
- Side airbags
- Seat cushion airbag
- Front passenger's seat belt buckle switch
- Driver's seat belt buckle switch
- Driver's seat position sensor
- Driver airbag
- Front passenger occupant classification system (ECU and sensors)
- Knee airbag
- SRS warning light
- Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) controls airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This information includes crash severity
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.
â– 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.
- The brakes and stop lights will be
controlled automatically.
- The interior lights will turn on automatically.
- The emergency flashers will turn
on automatically.
- Fuel supply to the engine will be
stopped.
- For Safety Connect subscribers, if
any of the following 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 assistance
required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dispatch
the necessary emergency
services.
- An SRS airbag is deployed.
- A seat belt pretensioner is activated.
- The vehicle is involved in a severe
rear-end collision.
â– 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
pretensioners 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 airbags for the front
passenger may deploy if luggage
is put in the seat, even if the seat
is unoccupied.
- The SRS seat cushion airbag on
the front passenger seat will not
operate if the occupant is not
wearing a seat belt.
â– 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] ).
- Both SRS curtain shield airbags
will deploy in the event of a side
collision on either side.
- Both SRS curtain shield airbags
will deploy in the event of vehicle
rollover.
- Both SRS curtain shield airbags
may also deploy in the event of a
severe frontal collision.
â– Conditions under which the
SRS airbags may deploy
(inflate), other than a collision
The SRS front airbags and SRS curtain
shield airbags may also deploy
if a serious impact occurs to the
underside of your vehicle. Some
examples are 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 SRS curtain shield airbags may
also deploy under the situations
shown in the illustration.
- The angle of vehicle tip-up is marginal.
- The vehicle skids and hits a curb
stone.
â– Types of collisions that may not
deploy 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 lowspeed
frontal collision. But, whenever
a collision of any type causes
sufficient forward deceleration of the
vehicle, deployment of the SRS front airbags may occur.
- Collision from the side
- Collision from the rear
- Vehicle rollover
â– 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.
- Collision from the side to the vehicle
body other than the passenger
compartment
- Collision from the side at an angle
The SRS side airbags do not generally
inflate if the vehicle is involved
in a frontal or rear collision, if it rolls
over, or if it is involved in a lowspeed
side collision.
- Collision from the front
- 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.
- Collision from the rear
- Pitching end over end
â– When to contact your Toyota
dealer
In the following cases, the vehicle
will require inspection and/or repair.
Contact your Toyota dealer as soon
as possible.
- Any of the SRS airbags have
been inflated.
- The front of the vehicle is damaged
or deformed, or was
involved in an accident that was
not severe enough to cause the
SRS front airbags to inflate.
- A portion of a door or its surrounding
area is damaged, deformed or
has had a hole made in it, or the vehicle was involved in an accident
that was not severe enough
to cause the SRS side and curtain
shield airbags to inflate.
- The pad section of the steering
wheel, dashboard near the front
passenger airbag or lower portion
of the instrument panel is
scratched, cracked, or otherwise
damaged.
- The seat cushion surface is
scratched, cracked, or otherwise
damaged.
- The surface of the seats with the
SRS side airbag is scratched,
cracked, or otherwise damaged.
- The portion of the front pillars, rear
pillars or roof side rail garnishes
(padding) containing the SRS curtain
shield airbags inside is
scratched, cracked, or otherwise
damaged.
WARNING
â– SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death
or serious injury.
Since the risk zone for the driver's
airbag is the first 2 - 3 in. (50 - 75
mm) of inflation, placing yourself
10 in. (250 mm) from your driver
airbag provides you with a clear
margin of safety. This distance is
measured from the center of the
steering wheel to your breastbone.
If you sit less than 10 in.
(250 mm) away now, you can
change your driving position in
several ways:
- Move your seat to the rear as
far as you can while still reaching
the pedals comfortably.
- Slightly recline the back of the
seat.
Although vehicle designs vary,
many drivers can achieve the
10 in. (250 mm) distance, even
with the driver seat all the way
forward, simply by reclining the
back of the seat somewhat. If
reclining the back of your seat
makes it hard to see the road,
raise yourself by using a firm,
non-slippery cushion, or raise
the seat if your vehicle has that
feature.
- If your steering wheel is adjustable,
tilt it downward. This
points the airbag toward your
chest instead of your head and
neck.
The seat should be adjusted as
recommended by NHTSA above,
while still maintaining control of
the foot pedals, steering wheel,
and your view of the instrument
panel controls.
- If the seat belt extender has
been connected to the front
seat belt buckles but the seat
belt extender has not also been
fastened to the latch plate of the
seat belt, the SRS front airbags
will judge that the driver and
front passenger are wearing the
seat belt even though the seat
belt has not been connected. In
this case, the SRS front airbags
may not activate correctly in a
collision, resulting in death or
serious injury in the event of a
collision. Be sure to wear the
seat belt with the seat belt
extender.
- The SRS front passenger airbag
also deploys with considerable
force, and can cause death
or serious injury especially if the
front passenger is very close to
the airbag. The front passenger
seat should be as far from the
airbag as possible with the seatback
adjusted, so the front passenger
sits upright.
- Improperly seated and/or
restrained infants and children
can be killed or seriously injured
by a deploying airbag. An infant
or child who is too small to use
a seat belt should be properly
secured using a child restraint
system. Toyota strongly recommends
that all infants and children
be placed in the rear seats
of the vehicle and properly
restrained. The rear seats are
safer for infants and children
than the front passenger seat.
- Do not sit on the edge of the
seat or lean against the dashboard.
- Do not allow a child to stand in
front of the SRS front passenger
airbag unit or sit on the knees of
a front passenger.
- Do not allow the front seat occupants
to hold items on their
knees.
- Do not lean against the door,
the roof side rail or the front,
side and rear pillars.
- Do not allow anyone to kneel on
the passenger seat toward the
door or put their head or hands
outside the vehicle.
- Do not attach anything to areas
such as a door, windshield, side
window, front or rear pillar, roof
side rail and assist grip.
- Vehicles without smart key system:
Do not attach any heavy,
sharp or hard objects such as
keys and accessories to the
key. The objects may restrict
the SRS knee airbag inflation or
be thrust into the driver's seat
area by the force of the deploying
airbag, thus causing a danger.
â– Modification and disposal of
SRS airbag system components
Do not dispose of your vehicle or
perform any of the following modifications
without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
- Installation, removal, disassembly
and repair of the SRS airbags
- Repairs, modifications, removal
or replacement of the steering
wheel, instrument panel, dashboard,
seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,

- Modifications to the front door
panel (such as making a hole in
it)
- Repairs or modifications of the
front fender, front bumper, or
side of the occupant compartment
- Installation of a grille guard (bull
bars, kangaroo bar, etc.), snow
plows, winches or roof luggage
carrier
- Modifications to the vehicle's
suspension system
- Installation of electronic devices
such as mobile two-way radios
and CD players
- Modifications to your vehicle for
a person with a physical disability
