Airbag sensor assembly
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. 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.
■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 EV system will be stopped. ( P. 9 0 )
●All of the doors will be unlocked. ( P.186)
●The brakes and stop lights will be con-
trolled automatically. ( P.406)
●The interior lights will turn on automat-
ically. ( P.432)
●The emergency flashers will turn on
automatically. ( P.506)
●If any of the following situations occur,
the system is designed to send an emergency call to the eCall control 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.
( P. 6 5 ) • 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 approxi-
mately 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 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 under- ride collision, such as a collision in which the front of the vehicle under-
rides, 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.
■SRS airbag deployment conditions
(SRS side and curtain shield air- bags and SRS front seat center air-bag)
●The SRS side and curtain shield air-bags and SRS front seat center airbag
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 1500 kg [3300 lb.] vehi-cle colliding with the vehicle cabin
from a direction perpendicular to the vehicle orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
●Both SRS curtain shield airbags will deploy in the event of a side collision

42

on either side.
●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 seri-ous 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
■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 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.
●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 and SRS front seat center airbag)
The SRS side and curtain shield airbags and SRS front seat center airbag 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 com- partment
●Collision from the side at an angle
The SRS side airbags and SRS front
seat center airbag do not generally inflate if the vehicle is involved in a fron-tal or rear collision, if it rolls over, or if it
is involved in a low-speed side collision.
●Collision from the front
●Collision from the rear
●Vehicle rollover

For safety and security
The SRS 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 rear
●Vehicle rollover
■When to contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer
In the following cases, the vehicle will require inspection and/or repair. Contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer 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 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, 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 and SRS front seat center airbag to inflate.
●The pad section of the steering wheel or dashboard near the front passen-
ger airbag is scratched, cracked, or otherwise damaged.
●The surface of the seats with the SRS side airbag and SRS front seat center airbag is scratched, cracked, or other-
wise damaged.
●The portion of the front pillars, rear pil-
lars or roof side rail garnishes (pad- ding) containing the SRS curtain shield airbags inside, is scratched,
cracked, or otherwise damaged.

WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags. Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the air-bag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation, placing yourself 250
mm (10 in.) 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 250 mm (10 in.) 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 ped-als comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 250
mm (10 in.) distance, even with the driver seat all the way forward, sim-ply 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 air-bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec- ommended above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument panel controls.
●The SRS front passenger airbag also deploys with considerable
force, and can cause death or seri- ous injury especially if the front pas-senger 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 air-bag. 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. ( P. 4 9 )

WARNING
●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 occu-
pants 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 or lean
anything against areas such as the dashboard or steering wheel pad.These items can become projec-
tiles when the SRS driver and front passenger airbags deploy.
●Do not attach anything to areas such as a door, windshield, side window, front or rear pillar, roof side
rail and assist grip. (Except for the speed limit label P.532)
●Do not hang coat hangers or other hard objects on the coat hooks. All of these items could become pro-
jectiles and may cause death or serious injury, should the SRS cur-tain shield airbags deploy.

WARNING
●Do not use seat accessories which cover the parts where the SRS side
airbags and SRS front seat center airbag inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the side airbags and SRS front seat center airbag from activating cor-
rectly, disable the system or cause the side airbags and SRS front seat center 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 airbag components or the front doors.
Doing so can cause the SRS air- bags to malfunction.
●Do not touch any of the component parts immediately after the SRS air-bags have deployed (inflated) as
they may be hot.
●If breathing becomes difficult after
the SRS airbags have deployed, open a door or window to allow fresh air in, or leave the vehicle if it
is safe to do so. Wash off any resi- due 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
any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or per-
form any of the following modifica- tions without consulting any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. The SRS airbags may mal-function or deploy (inflate) acciden-
tally, 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 or winches
●Modifications to the vehicle’s sus-
pension system
●Installation of electronic devices
such as RF-transmitter and CD players

1-2. Child safety
WARNING
WARNING
●Only put a forward-facing child restraint system on the front seat
when unavoidable. When installing a forward-facing child restraint on the front passenger seat, move the
seat as far back as possible. Failing to do so may result in death or seri-ous injury if the airbags deploy
(inflate).
●Do not allow the child to lean
his/her head or any part of his/her body against the door or the area of the seat, front or rear pillars, or roof
side rails from which the SRS side airbags or SRS curtain shield air-
bags deploy even if the child is seated in the child restraint system. It is dangerous if the SRS side and
curtain shield airbags inflate, and the impact could cause death or serious injury to the child.
●When a junior seat is installed, always ensure that the shoulder
belt is positioned across the center of the child’s shoulder. The belt should be kept away from the
child’s neck, but not so that it could fall off the child’s shoulder.

2-1. Electric vehicle system
Electric Vehicle system
12-volt battery
Provides electricity to various vehicle systems such as the SRS airbags, headlights,
wipers, etc.
*: AWD models only
■When braking (regenerative
braking)
The battery electric motor (traction
motor) charges the traction battery.
The driving range can be extended
by actively using this regenerative
braking to store electricity in the
traction battery.
The battery electric vehicle is
driven using electricity, which is
received from an external power
source and stored in the traction
battery. Not only public charging
stations, but also household sock-
ets can be used for charging. Pro-
cedures are different from refueling
a conventional vehicle. Therefore,
make sure to read the following
thoroughly.
 Charging equipment (P.95)
 AC charging cable (P. 9 8 )
 Power sources that can be used
( P.112)
 Things to know before charging
( P.118)
 How to charge your vehicle
( P.121, 129)
 When charging cannot be per-
formed normally ( P.152)
■Regenerative braking
In the following situations, kinetic energy
is converted to electric energy and deceleration force can be obtained in conjunction with the recharging of the
traction battery.
●The accelerator pedal is released
while driving with the shift position in D.
●The brake pedal is depressed while driving with the shift position in D.
■Charging the 12-volt battery
The 12-volt battery is charged from the
traction battery when the EV system is operated or while the traction battery is being charged.
If the vehicle has not been used for a long time, the 12-volt battery may become low due to self-discharge. If this
occurs, follow the correct procedures. ( P.544)
■When not using the vehicle for an
extended period of time
●When the vehicle will not be used for
an extended period of time, charge the traction battery once a month. This protects the traction battery from
extreme voltage decline due to self discharging.
●When the vehicle will not be used for an extended period of time, the 12-volt battery will be charged from the
traction battery to reduce the risk of the 12-volt battery discharged. In this case, the cooling fan may operate,
however it is not a malfunction.
●To prevent the 12-volt battery from
being discharged, do not leave the charging port lid open or the charging cable connected to the vehicle.
