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 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, simply 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 recommended above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.
● The SRS front passenger airbag also 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 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 sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 55)

WARNING
■SRS airbag precautions
●Vehicles without an SRS driver knee
airbag: Do not attach anything to or lean
anything against areas such as the
dashboard or steering wheel pad.
These items can become projectiles
when the SRS driver and front passen-
ger airbags deploy.
● Vehicles with an SRS driver knee
airbag: 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 projectiles
when the SRS driver, front passenger
and driver knee airbags deploy.
● Vehicles without SRS curtain shield
airbags: Do not attach anything to areas
such as a door, windshield and side
window.
● Vehicles with SRS curtain shield
airbags: Do not attach anything to areas
such as a door, windshield, side win-
dow, front or rear pillar, roof side rail and
assist grip. (Except for the speed limit
label P. 436)
● Vehicles with an SRS driver knee
airbag, but do not use 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 driver knee airbag infla-
tion or be thrust into the driver’s seat
area by the force of the deploying
airbag, thus causing a danger.

■ Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags, 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.
■ Types of collisions that may not deploy the SRS airbags (SRS front
airbags)
The SRS front airbags do not generally infl ate 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.
■ Types of collisions that may not deploy the SRS airbags
(SRS side airbags and SRS curtain shield airbags [if equipped])
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.
● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● 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

WARNING
■ 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 be used as long
as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is le ft “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 passenger
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.

Child restraint systems
Studies have shown that installing a child restraint on a rear seat is
much safer than installing one on the front passenger seat.
● Choose a child restraint system that suits your vehicle and is appro-
priate to the age and size of the child.
● For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual.
( P. 6 5 )
● If child restraint system regulations exist in the country where you
reside, please contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional for the child
restraint system installation.
● Toyota recommends that you use a child restraint system which
conforms to the regulation ECE No.44.
Toyota strongly urges the use of child restraint systems.
