Seat Precautions
When returning a rear seat to its original position, place the seat belt
in its normal position. Verify t hat the seat belt pulls out and retracts.
WARNING
■Make sure the adjustable components of a seat are locked in place
Adjustable seats and seatbacks that are not securely locked are dangerous.
In a sudden stop or collision, the seat or seatback could move, causing
injury. Make sure the adjustable components of the seat are loc ked in place
by attempting to slide the seat forward and backward and rocking the seat-
back.
■ Never allow children to adjust a seat
Allowing children to adjust a seat is dangerous as it could res ult in serious
injury if a child’s hands or feet become caught in the seat.
■ Do not drive with t he seatback unlocked
All of the seatbacks play an important role in your protection in a vehicle.
Leaving the seatback unlocked is dangerous as it can allow passengers to
be ejected or thrown around and baggage to strike occupants in a sudden
stop or collision, resulting in severe injury. After adjusting the seatback at
any time, even when there are no other passengers, rock the seatback to
make sure it is locked in place.
■ Adjust a seat only when the vehicle is stopped
If the seat is adjusted while the vehicle is being driven, the seating posture
may become unstable and the seat could move unexpectedly result ing in
injury.
■ Do not modify or replace the front seats
Modifying or replacing the front seats such as replacing the up holstery or
loosening any bolts is dangerous. The front seats contain air b ag compo-
nents essential to the supplemental restraint system. Such modi fications
could damage the supplemental restraint system and result in serious injury.
Consult your Toyota dealer if there is any need to remove or re install the
front seats.
■ Do not drive with d amaged front seats
Driving with damaged front seats, such as seat cushions torn or damaged
down to the urethane, is dangerous. A collision, even one not strong
enough to inflate the air bags, could damage the front seats wh ich contain
essential air bag components. If there was a subsequent collision, an air
bag may not deploy which could lead to injuries. Always have yo ur Toyota
dealer inspect the front seats, front seat belt pretensioners a nd air bags
after a collision.

Essential Safety Equipment
WARNING
■Do not drive with either front seats reclined
Sitting in a reclined position while the vehicle is moving is d angerous
because you do not get the full protection from seat belts. During sudden
braking or a collision, you can slide under the lap belt and su ffer serious
injuries. For maximum protection, sit well back and upright.
■ Do not place an object such as a cushion between the seatback a nd
your back
Putting an object such as a cushion between the seatback and yo ur back is
dangerous because you will be unable to maintain a safe driving posture
and the seat belt cannot function at its full capacity in a collision, which
could result in a serious accident, injury or death.
■ Do not place objects under the seat
The object could get stuck and cause the seat to not be fixed s ecurely, and
result in an accident.
■ Do not stack cargo hig her than the seatbacks
Stacking luggage or other cargo higher than the seatbacks is da ngerous.
During sudden braking or a collision, objects can fly around an d become
projectiles that may hit and injure passengers.
■ Make sure luggage and cargo is secured before driving
Not securing cargo while driving is dangerous as it could move or be
crushed during sudden braking or a collision and cause injury.
■ Never allow a passenger to sit o r stand on the folded seatback while
the vehicle is moving
Driving with a passenger on the folded seatback is dangerous. A llowing a
child to sit up on the folded seatback while the vehicle is mov ing is particu-
larly dangerous. In a sudden stop or even a minor collision, a child not in a
proper seat or child-restraint system and seat belt could be th rown forward,
back or even out of the vehicle resulting in serious injuries o r death. The
child in the baggage area could be thrown into other occupants and cause
serious injury.
■ Never give the car keys to children and do not allow them to pl ay in the
vehicle
Playing with the folding rear seats is dangerous. Once the seat backs are
back up, a child in the trunk would not be able to get out the way they had
entered. If you have small children, keep the seatbacks locked.

Rear Seat
By lowering the rear seatbacks the luggage compartment space can
be expanded.
Split Folding the Seatback
WARNING
■ Do not drive the vehicle with occupants on folded down seatbacks or
in the luggage compartment.
Putting occupants in the luggage compartment is dangerous because seat
belts cannot be fastened which could lead to serious injury or death during
sudden braking or a collision.
■ Do not allow children to play inside the vehicle with the seatb acks low-
ered.
Allowing children to play in the vehicle with the seatbacks folded down is
dangerous. If a child enters the luggage compartment and the se atbacks
were raised back up, the child may become trapped in the luggag e com-
partment which could lead to an accident.
■ Tightly secure cargo in the luggage compartment when it is tran s-
ported with the seatbacks folded down.
Driving without tightly securing cargo and luggage is dangerous as it could
move and become an obstruction to driving during emergency brak ing or a
collision resulting in an unexpected accident.
■ When transporting cargo, do not allow the cargo to exceed the height
of the seatbacks.
Transporting cargo stacked higher than the seatbacks is dangero us as visi-
bility to the rear and sides of the vehicle is reduced which could interfere
with driving operations and lead to an accident.

WARNING
■Always drive with the head restraints installed when seats are being
used and make sure they are properly installed
● Driving with the head restraints not installed is dangerous. Wi th no support
behind your head, your neck could be seriously injured in a col lision.
● When installing a head restraint, make sure that it is installed correctly with
the front of the head restraint facing forward. If the head res traint is
installed incorrectly, it could detach from the seat during a c ollision and
result in injury.
● The head restraints on each of the front and rear seats are spe cialized to
each seat. Do not switch around the head restraint positions. I f a head
restraint is not installed to its correct seat position, the ef fectiveness of the
head restraint during a collision will be compromised which cou ld cause
injury.
■ After installing a head restrain t, try lifting it to make sure that it does
not pull out
Driving with an unsecured head restraint is dangerous as the ef fectiveness
of the head restraint will be compromised which could cause it to unexpect-
edly detach from the seat.

Essential Safety Equipment
Seat Belt Precautions
All of the seat belt retractors are designed to keep the lap/shoulder
belts out of the way when not in use.
The driver’s seat belt has no provisions for child-restraint sy stems and
has only an emergency locking mode . The driver may wear it comfort-
ably, and it will lock during a collision.
However, the front passenger’s seat and all rear lap/shoulder b elt
retractors operate in two modes: emergency locking mode, and fo r
child-restraint systems, automatic locking mode. While we recom -
mend you put all children in the rear seats, if you must use th e front
passenger seat for a child, slide the front passenger seat as f ar back
as possible and make sure any ch ild-restraint system is secured prop-
erly.
Seat belts help to decrease the possibility of severe injury
during accidents and sudden st ops. Toyota recommends that
the driver and all passengers always wear seat belts.
WARNING
■ Always wear your seat belt and ma ke sure all occupants are properly
restrained
Not wearing a seat belt is extremely dangerous. During a collis ion, occu-
pants not wearing seat belts could hit someone or things inside the vehicle
or even be thrown out of the vehicle. They could be seriously i njured or
even killed. In the same collision, occupants wearing seat belt s would be
much safer.
