For safety and security
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 con- trolled automatically. ( P.357)
●The interior lights will turn on automat- ically. ( P.437)
●The emergency flashers will turned on automatically. ( P.502)
●Fuel supply to the engine will be stopped. ( P.510)
●Vehicles with eCall: If any of the fol-
lowing 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 automati- cally treats the call as an emergency
and helps to dispatch the necessary
emergency services. ( P. 6 9 ) • An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.*: In some cases, the call cannot be
made. ( P. 7 0 )
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold le vel (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 situ-
ations: • 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
■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 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 may
deploy in the event of a severe side collision.
●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 side
and curtain shield airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some exam-
ples 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

401-1. For safe use
■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)
The SRS side and curtain shield airbags
may not activate if the vehicle is sub- jected to a collision from the side at cer-
tain angles, or a collision to the side of
the vehicle body other than the passen- ger 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 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
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 case s, 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.

■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.

421-1. For safe use
WA R N I N G
●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.
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 pro-
vides 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 sev-
eral 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 airbag 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 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. (P. 4 8 )
●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, steering wheel pad and
lower portion of the instrument panel.
These items can become projec-
tiles when the SRS driver, front pas- senger 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. (Except for the speed limit label P.525)
●Vehicles without a smart entry & start 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.
●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.
●If a vinyl cover is put on the area
where the SRS driver’s knee airbag will deploy, be sure to remove it.

441-1. For safe use
WA R N I N G
●Do not use seat accessories which
cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the
side airbags from activating cor- rectly, disable the system or cause
the side airbags 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 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 your Toyota
retailer or Toyota authorized repairer, or any reliable repairer. The SRS
airbags may malfunction or deploy
(inflate) accidentally, causing death or serious injury.
●Installation, remo val, 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 mobile two-way radios
(RF-transmitter) and CD players

Exhaust gas precautions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WA R N I N G
Exhaust gases include harmful car-
bon monoxide (CO), which is color-
less and odorless. Observe the following precautions.
Failure to do so may cause exhaust
gases enter the vehicle and may lead to an accident caused by
light-headedness, or may lead to
death or a serious health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in the
vehicle even when the back door is closed, open the windows and have
the vehicle inspected at any author-
ized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area, such as a garage, stop the engine.
●Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be
avoided, park the vehicle in an open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in
an area with snow build-up, or where it is snowing. If snowbanks
build up around the vehicle while
the engine is running, exhaust gases may collect and enter the
vehicle.
■Exhaust pipe
The exhaust system needs to be
checked periodically. If there is a hole
or crack caused by corrosion, dam- age to a joint or abnormal exhaust
noise, be sure to have the vehicle
inspected and repaired by any author- ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer.

■When installing a child restraint
system
For safety reasons, always install a child restraint system in a rear seat. In
the event that the rear seat cannot be
used, the front seat can be used as long as the airbag manual on-off sys-
tem is set to “OFF”.
If the airbag manual on-off system is
left on, the strong impact of the airbag deployment (inflation) may cause
serious injury or even death.
■When a child restraint system is
not installed on the front passen-
ger seat
Ensure that the airbag manual on-off
system is set to “ON”.
If it is left off, the airbag may not deploy in the event of an accident,
which may result in serious injury or
even death.
Riding with children
Observe the following precau-
tions when children are in the
vehicle.
Use a child restraint system
appropriate for the child, until
the child becomes large
enough to properly wear the
vehicle’s seat belt.
 It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact with
the shift lever, wiper switch,
etc.
 Use the rear door child-protec-
tor lock or the window lock
switch to avoid children open-
ing the door while driving or
operating the power window
accidentally. ( P.123, 153)
 Do not let small children oper-
ate equipment which may
catch or pinch body parts,
such as the power window,
hood, back door, seats, etc.

WA R N I N G
■When children are in the vehicle
Never leave children unattended in
the vehicle, and never allow children to have or use the key.
Children may be able to start the vehi-
cle or shift the vehicle into neutral. There is also a danger that children
may injure themselves by playing with
the windows, the panoramic moon
roof, or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle
can be fatal to children.
Child restraint systems
Before installing a child
restraint system in the vehicle,
there are precautions that need
to be observed, different types
of child restraint systems, as
well as installation methods,
etc., written in this manual.
 Use a child restraint system
when riding with a small child
that cannot properly use a seat
belt. For the child’s safety,
install the child restraint sys-
tem to a rear se at. Be sure to
follow the insta llation method
that is in the operation manual
enclosed with the restraint sys-
tem.
 The use of a Toyota genuine
child restraint system is rec-
ommended, as it is safer to
use in this vehicle. Toyota gen-
uine child restraint systems
are made specifically for
Toyota vehicles. They can be
purchased at a Toyota dealer.
