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
folded down 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 accessories for the
seats which cover the parts where
the side airbags inflate. Such acces-
sories may prevent the side airbags
from activating 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, push
back your body to make sure it is
locked in position.

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.
CAUTION
Adjustment should not be made
while the vehicle is moving.
When adjusting the seat, be careful
that the seat does not hit a passen-
ger or luggage.
Third seats only: Adjust both seat
cushions to the same position and
align both seatbacks at the same
angle when a person sits in the
third seat center position. Other-
wise, the person cannot wear the
seat belt properly and this may
cause serious injuries in a collision.
After adjusting the seat position,
try sliding it forward and backward
to make sure it is lock in position.
After adjusting the seatback, push
back your body to make sure it is
locked in position.
When returning seats to their original
position, observe the following pre-
cautions in order to prevent personal
injury in a collision or sudden stop:
Make sure the seat is securely
locked by pushing forward and rear-
ward on the top of the seatback
and by trying to pull up the edge
of the bottom cushion. Failure to
do so will prevent the seat belt
from operating properly.
Make sure the seat belts are not
twisted or caught under the seat
and are arranged in their proper
position and are ready to use.
Folding the seats up will enlarge the lug-
gage compartment. See “Luggage stowage
precautions” in Section 2 for precautions
in loading luggage.
