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 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.

If the seat legs are locked in the wrong
position, pull up the left side lever un-
der the seat. Then lift and remove the
seat.Ty p e A

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.
On some models, you can also move the
head restraint forward or backward. If
such adjustment is desired, pull or push
the head restraint.
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.

CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatbacks too
much. The seat belts provide maxi-
mum protection when the seatbacks
are in the upright position. (Refer
to the seat adjustment instructions.)
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers—they may severely weaken the
belts. (See “Cleaning the interior”
in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely.

If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.
When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” in this section.) To free the belt
again, fully retract the belt and then pull
the belt out once more.
CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed. It cannot
protect an adult occupant or your
child from injury.
Seat belts with an adjustable shoulder
anchor—
Adjust the shoulder anchor position to
your size.
To raise: Slide the anchor up.
To lower: Push in the lock release button
and slide the anchor down.
After adjustment make sure the anchor is
locked in position.
CAUTION
Always make sure the shoulder belt
is positioned across the center of
your shoulder. The belt should be
kept away from your neck, but not
falling off your shoulder. Failure to
do so could reduce the amount of
protection in an accident and cause
serious injuries in a collision.
