SRS airbag precautions

●

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 air-
bag 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 sys-
tem. 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. (

P. 58)

●

If the seat belt extender has been con-
nected 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.

SRS airbag precautions

●

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 pil-
lars.

●

Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.

WARNING

■

SRS airbag precautions

●

Do not hang coat hangers or other hard objects on the coat hooks. All of
these items could become projectiles and may cause death or serious
injury, should the SRS curtain shield airbags deploy.

●

If a vinyl cover is put on the area where the SRS knee airbag will deploy,
be sure to remove it.

●

Do not use seat accessories which cover the parts where the SRS side
airbags and SRS seat cushion airbag inflate as they may interfere with
inflation of the SRS airbags. Such accessories may prevent the side air-
bags and seat cushion airbag from activating correctly, disable the system
or cause the side airbags and seat cushion airbag to inflate accidentally,
resulting in death or serious injury.

●

Do not strike or apply significant levels of force to the area of the SRS air-
bag components or the front doors.
Doing so can cause the SRS airbags to malfunction.

●

Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.

●

Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.

●

Do not attach anything to areas such as
a door, windshield, side windows, front
or rear pillar, roof side rail and assist
grip.

WARNING

■

SRS airbag precautions

●

If breathing becomes difficult after the SRS airbags have deployed, open a
door or side window to allow fresh air in, or leave the vehicle if it is safe to
do so. Wash off any residue as soon as possible to prevent skin irritation.

●

If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.

●

Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.

■

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, front door trims or front door
speakers

●

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

■

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 hybrid system will be stopped and fuel supply to the engine will be
stopped. (

P. 99)

●

The emergency flashers will turn on automatically. (

P. 652)

●

For Safety Connect subscribers, if any of the following situations occur, the
system is designed to send an emergency call to the response center, noti-
fying them of the vehicle’s location (without needing to push the “SOS” but-
ton) 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. (

P. 76)

• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.

■

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 and seat cushion airbag 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.

●

The SRS seat cushion airbag on the front passenger 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]).

●

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.

■

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.

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
frontal or rear collision, if it rolls over, or if it is involved in a low-speed side
collision.

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.

WARNING

■

Front passenger occupant classification 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 plate has not been left inserted
into the buckle before someone sits in the front passenger seat.

●

Make sure the “AIR BAG OFF” indicator light 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, and 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 illumi-
nated, the SRS airbags for the front passenger will not activate, which
could cause death or serious injury in the event of a collision.

●

Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).

●

Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat 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 SRS airbags for the front passenger will not acti-
vate in the event of a severe accident. If the seatback touches the rear
seat, return the seatback 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.

WARNING

■

Front passenger occupant classification 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 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 still
remains 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 a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. (

P. 58)

●

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 of the
front passenger occupant classification 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 and seat cover, that cov-
ers the seat cushion surface.

●

Do not modify or replace the upholstery of the front seat.

●

Adjust the front passenger seat so that the head restraint does not touch
the ceiling. If the head restraint is left in contact with the ceiling, the system
may not detect the front passenger properly, leading to improper operation
of the airbags.
