SRS airbag deployment conditions (front airbags)
● The SRS front airbag will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to a 12 - 18 \
mph
[20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbags will not activate, if there is no passen-
ger sitting in the front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 126)
■ SRS airbag deployment conditions (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 a 3300 lb. [1500 kg] vehicle colliding with the vehi-
cle cabin from a direction perpendicular to the vehicle orientation at a speed
of 12 - 18 mph [20 - 30 km/h]).

SRS airbag precautions
Observe the following precautions regarding the 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.
The National Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver 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 cen-
ter of the steering wheel to your breastbone. If you sit less than 10 in. (250
mm) 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
pedals comfortably.
• Slightly recline the back of the seat. 
Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) 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 recommended by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.

CAUTION
■SRS airbag precautions
● 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 air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● A deploying airbag can cause death or serious injuries to improperly
seated and/or restrained infants and children. 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 the safest for infants and children. ( P. 132)
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s air-
bag system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the driver’s airbag may not
activate correctly in a collision, resulting
in death or serious injury in the event of
collision. Be sure to wear the seat belt
with the seat belt extender.

There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a
smaller adult sits in the front pa ssenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2: In the event the front passenge r does not wear a seat belt.
*3: When a large child who has outgrown a child restraint system sits
in the front passenger seat, the system may recognize him/her as
an adult depending on his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front pas- senger seat. A forward-facing chil d restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P. 132)
*5: In case the indicator is not illumin ated, consult this manual as for
installing the child restraint system properly. ( P. 137)

CAUTION
■Front passenger occupant cl assification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system. 
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt tab has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, then reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-
nated, the front passenger airbag on the front passenger side may not
activate correctly, which could cause death or serious injury in the event of
collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.
● Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the passenger’s airbags will not deploy in the event of
a severe accident. If the seatback touches the rear seat, return the seat-
back to a position where it does not touch the rear seat. Keep the front\

passenger seatback as upright as possible when the vehicle is moving.
Reclining the seatback excessively may lessen the effectiveness of the
seat belt system.

Front passenger occupant cl assification system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator light is illuminated, ask
the passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the “AIR BAG OFF” indicator light still
remain illuminated, either ask the passenger to move to the rear seat, or if
that is not possible, move the front passenger seat fully rearward.
● When it is unavoidable to install the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( P. 137)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction on the
detection system. In this case, contact your Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion or seat cover, that covers
the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.
