WARNING
■SRS airbag precautions
● If a vinyl cover is put on the area where the SRS driver’s 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 interfe re with
inflation of the SRS airbags. Such accessories may prevent the side
airbags and seat cushion airbag from activating correctly, disa ble the sys-
tem or cause the side airbags and seat cushion airbag to inflate acciden-
tally, resulting in death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS
airbag 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
airbags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deplo yed, open a
door or window to allow fresh air in, or leave the vehicle if i t is safe to do
so. Wash off any residue as soon as possible to prevent skin ir ritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillars garnishes, are damaged or cracke d, 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of a collision.

WARNING
■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 airbag s
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, s ide and rear
pillars or roof side rails or front door panels, trims and spea kers
● 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 radio s and CD
players
● Modifications to your vehicle for a person with a physical disa bility

■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 g ases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover an d 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 h ot.
● The windshield may crack.
● Fuel supply to the engine will be stopped. (→P. 433)
● 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 t he “SOS” but-
ton) and an agent will attempt to speak with the occupants to a scertain the
level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emer gency 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 condi tions (SRS front airbags)
● The SRS front airbags will deploy i n the event of an impact tha t exceeds the
set threshold level (the level of force corresponding to an app roximately
12 - 18 mph [20 - 30 km/h] frontal collision with a fixed wall th at 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 th e seat belt pre-
tensioners will activate.
● 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 a irbags)
● The SRS side and curtain shield airbags will deploy in the even t 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 may deploy in the event of a severe side
collision.
● Both SRS curtain shield airbags will deploy in the event of veh icle rollover.
● Both SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.
■ Conditions under which the SRS ai rbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS curtain shield airbags may also d eploy if a
serious impact occurs to the underside of your vehicle. Some ex amples are
shown in the illustration.
The SRS curtain shield airbags may also deploy under the situat ions 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 fr ont
airbags)
The SRS front airbags do not generally inflate if the vehicle i s 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 suffici ent forward
deceleration of the vehicle, deployment of the SRS front airbag s may occur.
■ Types of collisions that may not deploy the SRS airbags (SRS si de 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 involv ed in a low-speed side
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 front
● Collision from the rear
● Vehicle rollover

461-1. For safe use
C-HR_OM_USA_OM10684UThe 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-

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 other-
wise damaged.
