CAUTION
When folding or returning the seats,
observe the following precautions in
order to prevent personal injury:
Make sure that the seat path is
clear before moving the seat. Other-
wise, injury may result from contact
with the seat.
Be careful not to allow hands or
feet to get caught or pinched in the
seat.
When returning the seats to their
original position, make sure the seat
belts are not twisted or caught in the
seatback. It could result in serious
injuries in a sudden braking or a col-
lision.
Do not shift the automatic transmis-
sion selector lever out of “P” with
the engine switch in “ON” during the
operation. Doing so may cause the
vehicle to move and result in serious
personal injury.
This “3RD SEAT” warning light warns the
third seat operation is not yet complete
when the engine switch is turned to the
“ON” position. The third seats can be stowed by push-
ing and holding the stowing switch that
is inside the back door opening on the
outer edge of the ceiling.
Before stowing the third seats:
Stow the seat belt buckles and center
seat belt. (See “—Stowing seat belt
buckles of the second and third seats”
on page 114 and “—Stowing the center
seat belt of the third seats” on page 114
in this Section.)
Lower the head restraint to the lowest
position. (See “Head restraints” on
page 106 in this Section.)
Make sure that there is no object on
the seat cushion, floor around the
seats and floor of the luggage compart-
ment. If an object is caught during the
operation, seat operation will stop.

Third seats
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.
Third seats—When an occupant sits on
the seat, always pull up the head restraint
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.

The driver and front passenger seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the sensor detects a severe frontal
impact, the front seat belts are quickly
drawn back by the retractors so that the
belts snugly restrain the occupants.The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger’s
seat belt pretensioner may activate if lug-
gage is put on the seat, or the seat belt
is buckled up regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “—Front pass
enger occupant
classification system” on page 135 in this
Section.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification system (ECU and sensors)
4. Seat belt pretensioner assemblies
5. Front passenger ’s seat belt buckle switch
6. Airbag sensor assembly

If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
When the engine switch is turned to
the “ON” position, the light does not
come on, remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.
In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
Your vehicle is equipped with “ADVANCED
AIRBAGS” designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor etc. The front
passenger ’s airbag system consists of the
front passenger occupant classification
sensor etc.
