84 1-7. Safety information
■SRS airbag deployment conditions (SRS front airbags/SRS seat cush-
ion airbags)
● The SRS front airbags and seat cushion airbags will deploy in the event
of an impact that exceeds the set threshold level (the level of force corre-
sponding to an approximately 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 and 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, SRS seat cushion airbags and the seat belt pretensioners may not
activate together.
● The SRS front airbags and seat cushion airbag for the front passenger
will not activate if there is no passenger sitting in the front passenger
seat. However, the SRS front airbags and seat cushion airbag for the
front passenger may deploy if luggage is put in the seat, even if the seat
is unoccupied.
● The SRS seat cushion airbags on the front seats will not operate if the
occupant is not wearing a seat belt.
■ SRS airbag deployment conditions (S RS side and curtain shield air-
bags)
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 3300 lb. [1500 kg] vehicle collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orien-
tation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).

88 1-7. Safety information
CAUTION
■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.
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 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 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, 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 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.

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.
● 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 properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( →P. 98)
●If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be sure
to wear the seat belt with the seat belt
extender.
●Do not sit on the edge of the seat or
lean against the dashboard.

CAUTION
■Front passenger occupant cl assification system precautions
Observe the following precautions regarding the front passenger occupant
classification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt plate 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, and 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 SRS airbags for the passenger 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 seat 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.

CAUTION
■
Front passenger occupant cl assification system precautions
● 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.
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator 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 still
remains 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 a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. ( →P. 102)
● 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 of 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 and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

1-7. Safety information
Child restraint systems
Points to rememberStudies 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 th at suits your vehicle and is
appropriate 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. 102)
Types of child restraints
Child restraint systems are clas sified into the following 3 types
according to the age and size of the child:
Rear facing — Infant seat/convertible seat
A child restraint system for a small ch ild or baby must itself be prop-
erly restrained on the seat with the lap portion of the lap/shoulder
belt.
The laws of all 50 states of the U.S.A. and Canada now require the
use of child restraint systems.
