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
■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 airbags)
The SRS side and curtain shield airbags and SRS front seat center 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.
●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 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

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 air-
bag 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 breast-
bone. 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 7 )

WARNING
●Do not use seat accessories which cover the parts where the SRS side
airbags and SRS front seat center airbags inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the SRS side airbags and SRS front seat center airbags from activating
correctly, disable the system or cause the SRS side airbags and SRS front seat center airbags 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 your Toyota retailer or Toyota authorized repairer,
or any reliable repairer. The SRS air- bags 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 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

Child restraint systems
Before installing a child
restraint system in the vehicle,
there are precautions that need
to be observed, different types
of child restra int 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 seat. Be sure to
follow the installation 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.

■When installing a child
restraint system to a front pas-
senger seat
For the safety of a child, install a
child restraint system to a rear seat.
When installing a child restraint
system to a front passenger seat is
unavoidable, adjust the seat as fol-
lows and install the child restraint
system:
 Move the front seat fully rear-
ward.
 Adjust the seat height to the
upper most position.
 Adjust the seatback angle to the
most upright position.

WARNING
●For effective protection in automo- bile accidents and sudden stops, a
child must be properly restrained, using a seat belt or child restraint system which is correctly installed.
For installation details, refer to the operation manual enclosed with the child restraint system. General
installation instruction is provided in this manual.
●Toyota strongly urges the use of a proper child restraint system that conforms to the weight and size of
the child, installed on the rear seat. According to accident statistics, the child is safer when properly
restrained in the rear seat than in the front seat.
●Holding a child in your or someone else’s arms is not a substitute for a child restraint system. In an acci-
dent, the child can be crushed against the windshield or between the holder and the interior of the
vehicle.
■Handling the child restraint sys-
tem
If the child restraint system is not properly fixed in place, the child or
other passengers may be seriously injured or even killed in the event of sudden braking, sudden swerving, or
an accident.
●If the vehicle were to receive a
strong impact from an accident, etc., it is possible that the child restraint system has damage that is
not readily visible. In such cases, do not reuse the restraint system.
●Depending on the child restraint system, installation may be difficult or impossible. In those cases,
check whether the child restraint system is suitable for installment in the vehicle. ( P.51) Be sure to
install and observe the usage rules after carefully reading the child restraint system fixing method in
this manual, as well as the opera- tion manual enclosed with the child restraint system.
●Keep the child restraint system properly secured on the seat even if
it is not in use. Do not store the child restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment.
