For safety and security
WARNING
●The SRS driver airbag deploys
with considerable force, and
can cause death or serious
injury especially i f 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 provides
you with a clear margin of
safety. This distance is mea-
sured from the center of the
steering wheel to your breast-
bone. 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 reach-
ing 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 adjust- able, tilt it downward. This
points the airbag 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.
●If the seat belt extender has
been connected 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 passenger are wearing the
seat belt even though the seat
belt has not been connected. In
this case, the SRS front airbags
may not activate correctly in a
collision, resulting in death or
serious injury in the event of a
collision. Be su re to wear the
seat belt with the seat belt
extender.
●The SRS front passenger air-
bag also deploys with consider-
able 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 seat-
back adjusted, so the front pas-
senger 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 recom-
mends that all infants and chil-
dren 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.58)

481-1. For safe use
WARNING
●Do not sit on the edge of the
seat or lean against the dash-
board.
●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 seats 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 pro-
jectiles when the SRS driver,
front passenger and driver’s
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.

521-1. For safe use
WARNING
●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” indi-
cator light is illuminated, discon-
nect the extender tongue from
the seat belt buckle, and recon-
nect 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” indi-
cator light is illuminated, the
SRS airbags for the front pas-
senger will not activate, which
could cause death or serious
injury in the ev ent of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. seatback pocket).
●Do not put weight on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.
●Do not recline t he front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “AIR BAG OFF” indi-
cator light to be illuminated,
which indicates that the SRS
airbags for the front passenger
will not activate in the event of a
severe accident. If the seatback
touches the rear seat, return the
seatback to a position where it
does not touch the rear seat.
Keep the front passenger seat-
back as upright as possible
when the vehicle is moving.
Reclining the seatback exces-
sively may lessen the effective-
ness of the seat belt system.
●If an adult sits i n the front pas-
senger seat, the “AIR BAG ON”
indicator light i s 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 illumi nated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger 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 passenger
seat in the proper order.
(  P.61)
●Do not modify or remove the
front seats.
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light m ay come on to
indicate a malfu nction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.

Riding with children
Observe the following pre-
cautions 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 sliding door child-
protector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.142, 203)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children ma y injure them-
selves by playing with the side
windows, the moon roof (if
equipped) or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.
