Adjust the angle of the seat-
back so that you are sitting
straight up and so that you do
not have to lean forward to

Adjust the seat so that you
can depress the pedals fully
and so that your arms bend
slightly at the elbow when
gripping the steering wheel.
( P.169)
Lock the head restraint in
place with the center of the
head restraint closest to the
top of your ears. ( P.182)

■Before driving
●Check that the floor mat is
securely fixed in the correct
place with all the provided
retaining hooks (clips). Be espe-
cially careful to perform this
check after cleaning the floor.
●With the hybrid system stopped
and the shift lever in P, fully
depress each pedal to the floor
to make sure it does not inter-
fere with the floor mat.
For safe driving
For safe driving, adjust the

been inflated.
●The front of the vehicle is dam-
aged or deformed, or was
involved in an accident that was
not severe enough to cause the
SRS front airbags to inflate.
●A portion of a door or its surround-
ing area is damaged, deformed or
has had a hole made in it, or the
vehicle was involved in an acci-
dent that was no t severe enough
to cause the SRS side and curtain
shield airbags to inflate.
●The pad section of the steering
wheel, dashboard near the front
passenger airbag o r lower portion
of the instrument panel is
scratched, cracked, or otherwise
damaged.
●The front passenger’s seat cush-
ion surface is scratched, cracked,
or otherwise damaged.
●The surface of the seats with the
SRS side airbag is scratched,
cracked, or otherwise damaged.
●The portion of the front pillars, rear
pillars or roof side rail garnishes
(padding) containing the SRS cur-
tain shield airbags inside is
scratched, cracked, or otherwise
damaged.
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 supple-
mental devices to be used with
the seat belts.

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.
