Approximately five hours after
the hybrid system is turned off, you may hear sound coming
from under the vehicle for sev-
eral minutes. This is the sound
of a fuel evaporation leakage
check and, it does not indicate a
malfunction.

cals. If the vehicle is scrapped
with the airbags and seat belt
pretensioners left as they are,
this may cause an accident such
as fire. Be sure to have the sys-
tems of the SRS airbag and seat
belt pretensioner removed and
disposed of by a qualified ser-
vice shop or by your Toyota
dealer before you scrap your
vehicle.

WARNING
■General precautions while
driving
Driving under the influence: Never
drive your vehicle when under the
influence of alcohol or drugs that
have impaired your ability to oper-
ate your vehicle. Alcohol and cer-
tain drugs delay reaction time,
impair judgment and reduce coor-
dination, which could lead to an
accident that could result in death
or serious injury.
Defensive driving: Always drive
defensively. Anticipate mistakes
that other drivers or pedestrians
might make and be ready to avoid
accidents.
Driver distraction: Always give
your full attention to driving. Any-
thing that distracts the driver,
such as adjusting controls, talking
on a cellular phone or reading can
result in a collisio n with resulting
death or serious injury to you,
your occupants or others.

bag 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 sever-
ity 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.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed of deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the parts
around the airbags 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.87)
●The brakes and st op lights will be
controlled automatically.
(  P.425)
●The interior lights will turn on auto-
matically. ( P.446)
●The emergency flashers will turn
on automatically. ( P.546)
●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 a ttempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency services. (

• When an SRS airbag has been deployed
• When a seat belt pretensioner has
operated
• When the vehicle has been involved in a severe rear-end colli-
sion
■The SRS airbags deploy in a
frontal impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds a threshold level
(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):
• SRS front airbags
●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle underrides, or goes under, the
bed of a truck
●Depending on the type of collision,
only the following may deploy:
• Seat belt pretensioners
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passenger in the front
passenger seat. However, the
SRS airbags for the front passen-
ger’s seat may deploy, even if the
seat is unoccupied, if luggage is
put on the seat.

381-1. For safe use
●In the event of an especially
severe frontal collision, the left
and right SRS curtain shield air-
bags may also deploy.
■The SRS airbags deploy in a
side impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds the set threshold
level (level of force corresponding
to the impact force produced by
an approximately 3300 lb. [1500
kg] vehicle collidin g with the pas-
senger compartment at a perpen-
dicular angle at an approximate
speed of 12 - 18 mph [20 - 30
km/h]):
• SRS side airbags
• SRS curtain shield airbags
●In the event of a side collision,
regardless of the impacted side,
both the left and right SRS curtain
shield airbags will deploy.
●If the vehicle is involved in a roll-
over, the following SRS airbags
will deploy:
• Both left and right SRS curtain shield airbags
■The SRS airbags deploy in an
underside impact when
●The following airbags may deploy
if the underside of the vehicle col-
lides with a hard object:
• SRS front airbags
• SRS side airbags
• SRS curtain shield airbags
●The following airbags may deploy
if the vehicle becomes signifi-
cantly tilted or is strongly impacted
by skidding into a curb, etc.:
• SRS curtain shield airbags
■The SRS side airbags will not
deploy when
●The following SRS airbags will not
normally deploy in side or rear col-
lisions, vehicle rollovers, or low
speed frontal collisions. However,
if such a collision causes sufficient
sudden deceleration, the SRS air-
bags may deploy.
• SRS front airbags
●The following SRS airbags may
not deploy if the vehicle is collided
with at a certain angle or in a side
collision where an area of the
vehicle other than the passenger
compartment is collided with:
• SRS side airbags
• SRS curtain shield airbags
●The following SRS airbags will not
normally deploy in front or rear
collisions, vehicle rollovers, or low
speed side collisions:
• SRS side airbags

WARNING
■SRS airbag precautions
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
●The driver and all passengers
must wear their seat belts cor-
rectly.
The SRS airbags are supple-
mental 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 airbag. The
National Highway Traffic Safety
Administration (NHTSA)
advises:
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 breast-
bone. If your current driving posi-
tion places you less than 10 in.
(250 mm) away from the driver
airbag, you can change your driv-
ing position in several ways:
• Move your seat to the rear as far as possible while still being
able to reach the pedals com-
fortably.
• Slightly recline the seatback. 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
seatback somewhat. If reclining
the seatback makes it hard to
see the road, raise yourself by
using a firm, non-slippery cush-
ion, or raise the seat if your
vehicle has that feature.
• If your steering wheel is adjust- able, tilt it downward. This
points the airbag toward your
chest instead of your head and
neck. The seat should be
adjusted as recommended by
the NHTSA, while still being
able to control the vehicle with
the pedals and steering wheel,
and maintaining your view of the
instrument panel controls.
●If a seat belt extender has been
connected to the passenger’s
seat belt buckle but the latch
plate of the passenger’s seat
belt has not been fastened to
the seat belt extender, the SRS
airbag system will judge that the
occupant is wearing the seat
belt even though the seat belt
has not been fastened. In this
case, the SRS front airbags for
the passenger may not deploy
correctly in a collision, resulting
in death or serious injury. Be
sure to wear the seat belt cor-
rectly when using a seat belt
extender.

For safety and security
WARNING
●The SRS front passenger air-
bag 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 positioned as far
possible from the airbag with
the seatback adjusted so that
the passenger is sat 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 recom-
mends that all infants and chil-
dren 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.51)
●Do not sit on the edge of the
seat or lean against the dash-
board.
●Do not allow a child to stand in
front of the SRS front passenger
airbag or sit on the lap of a front
passenger.
●Front seat occupants should
never hold items on their lap.
●Do not lean against the door,
roof side rail, or front, side, or
rear pillar.
●Do not allow anyone to kneel on
a 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 steer-
ing wheel pad.
