While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow sitting on top of a
foldeddown seatback, or in the
luggage compartment or cargo area.
Persons not properly seated and/or
properly restrained by seat belts
can be severely injured in the event
of emergency braking or a collision.
During driving, do not allow pas-
sengers to stand up or move
around between seats. Severe inju-
ries can occur in the event of emer-
gency braking or a collision.
CAUTION
The SRS side airbags are installed in
the driver and front passenger seats.
Observe the following precautions.
Do not lean against the front door
when the vehicle is in use, since
the side airbag inflates with consid-
erable speed and force. Otherwise,
you may be killed or seriously in-
jured.
Do not use seat accessories which
cover the parts where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.
Do not modify or replace the seats
or upholstery of the front seats
with the side airbags. Such changes
may disable the system or cause
the side airbags to inflate acciden-
tally, resulting in death or serious
injury. Consult your Toyota dealer if
you insist on modifications of this
kind.
Adjust the driver’s seat so that the foot
pedals, steering wheel and instrument
panel controls are within easy reach of
the driver.
CAUTION
Adjustments should not be made
while the vehicle is moving, as the
seat may unexpectedly move and
cause the driver to lose control of
the vehicle.
When adjusting the seat, be careful
that the seat does not hit a passen-
ger or luggage.
After adjusting the seat position,
try sliding it forward and backward
to make sure it is locked in posi-
tion.
After adjusting the seatback, exert
body pressure to make sure it is
locked in position.
Do not put objects under the seats.
Otherwise, the objects may interfere
with the seatlock mechanism or
unexpectedly push up the seat posi-
tion adjusting lever and the seat
may suddenly move, causing the
driver to lose control of the vehicle.

CAUTION
To reduce the risk of sliding under
the lap belt during a collision, avoid
reclining the seatback any more than
needed. The seat belts provide maxi-
mum protection in a frontal or rear
collision when the driver and the pas-
senger are sitting up straight and
well back in the seats. If you are
reclined, the lap belt may slide past
your hips and apply restraint forces
directly to the abdomen. In the event
of a frontal collision, the more the
seat is reclined, the greater the risk
of personal injury.

passengers are sitting up straight
and well back in the seats. If you
are reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen. In
the event of a frontal collision, the
more the seat is reclined, the great-
er the risk of personal injury.

NOTICE
Do not fold the seatback forward
while the luggage cover is set.

For your safety and comfort, adjust the
head restraint before driving.
To raise: Pull it up.
To lower: Push it down while pressing the
lock release button.
Front head restraints only—On some mod-
els, you can also move the front head
restraint forward or backward. If such ad-
justment is desired, pull or push the head
restraint.
Rear center head restraint—When an oc-
cupant sits on the rear center seat, al-
ways pull up the rear center head re-
straint to the lock position.
The head restraint is most effective when
it is close to your head. Therefore, using
a cushion on the seatback is not recom-
mended.
CAUTION
Adjust the center of the head re-
straint so that it is closest to the
top of your ears.
After adjusting the head restraint,
make sure it is locked in position.
Do not drive with the head re-
straints removed.
