Key off operation: If all the side doors
and back door are closed, it works for 43
seconds even after the ignition switch is
turned off. It stops working when either
front door is opened.
Jam protection function:
If something gets caught between the
moon roof and frame during slide clos-
ing operation, the moon roof stops and
then opens slightly.
If something gets caught between the
moon roof and frame during tilting
down operation, the moon roof stops
and then tilts up fully.
If the moon roof receives a strong impact,
this function may work even if nothing is
caught.
If the battery is disconnected or run
down, the moon roof may not operate
automatically and the jam protection func-
tion will not function correctly after you
reconnect, replace or recharge the battery.
In any of these cases, you should normal-
ize the moon roof.
To normalize the moon roof, push and
hold the switch toward the “TILT UP” side.
The moon roof will tilt up and down, then
slide open and close. After the slide close
operation, release the switch. Make sure that the moon roof opens and
closes automatically. If the moon roof can-
not be operated properly, have it checked
by your Toyota dealer.
CAUTION
To avoid serious personal injury, you
must do the following.
While the vehicle is moving, always
keep the heads, hands and other
parts of the bodies of all occupants
away from the roof opening. Other-
wise, they could be seriously in-
jured if the vehicle stops suddenly
or if the vehicle is involved in an
accident.
Before you close the moon roof,
always make sure there is nobody
around the moon roof. You must
also make sure nobody places his
or her head, hands and other parts
of the body in the roof opening. If
someone’s neck, head or hands get
caught in the closing roof, it could
result in a serious injury. When
anyone closes the moon roof, first
make sure it is safe to do so.
Be sure to remove the ignition key
when you leave your vehicle.
Never leave anyone (particularly a
small child) alone in your vehicle,
especially with the ignition key still
inserted. Otherwise, he/she could
use the moon roof switch and get
trapped in the roof opening. Unat-
tended person (particularly a small
child) can be involved in a serious
accident.
Never sit on top of the vehicle
around the roof opening.
Never try jamming any part of your
body to activate the jam protection
function intentionally.
The jam protection function may
not work if something gets caught
just before the moon roof is fully
closed.

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 any passengers to sit on
top of a foldeddown seatback, or
in the luggage compartment or car-
go area. Persons not properly
seated and/or not properly re-
strained by seat belts can be se-
verely injured in the event of emer-
gency braking or a collision.
During driving, do not allow any
passengers to stand up or move
around between seats. Otherwise,
severe injuries can occur in the
event of emergency braking or a
collision.
Driver seat
CAUTION
The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if
the driver is very close to the airbag.
The National Highway Traffic Safety
Administration (“NHTSA”) advises:
Since the risk zone for driver airbag
is the first 50—75 mm (2—3 in.) of
inflation, placing yourself 250 mm (10
in.) from your driver airbag provides
you with a clear margin of safety.
This distance is measured from the
center of the steering wheel to your
breastbone. If you sit less than 250
mm (10 in.) away now, you can
change your driving position in sever-
al ways:
Move your seat to the rear as far
as you can while still reaching the
pedals comfortably.
Slightly recline the back of the
seat. Although vehicle designs vary,
many drivers can achieve the 250
mm (10 in.) distance, even with the
driver seat all the way forward, sim-
ply by reclining the back of the
seat somewhat. If reclining the back
of your seat makes it hard to see
the road, raise yourself by using a
firm, nonslippery cushion, or raise
the seat if your vehicle has that
feature.
If your steering wheel is adjustable,
tilt it downward. This points the air-
bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec-
ommended by NHTSA above, while
still maintaining control of the foot
pedals, steering wheel, and your view
of the instrument panel controls.

Front passenger seat
CAUTION
The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury es-
pecially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the
airbag as possible with the seatback
adjusted, so the front passenger sits
upright.
Front seats (with SRS side airbags)
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 area 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 seats equipped
with side airbags. Such change may
prevent the side airbag system from
activating correctly, disable the sys-
tem or cause the side airbag sys-
tem to inflate accidentally, resulting
in death or serious injury.
CAUTION
Do not adjust the seat while the
vehicle is moving as the seat may
unexpectedly move and cause the
driver to lose control of the vehicle.
Be careful that the seat does not
hit a passenger or luggage.
After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.
After adjusting the seatback, push
your body back against the seat to
make sure the seat 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
front passenger 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.

When returning the seatback to the
upright position, observe the follow-
ing precautions in order to prevent
personal injury in a collision or
sudden stop:
Make sure the seatback is securely
locked by pushing forward and rear-
ward on the top of the seatback.
Failure to do so will prevent the
seat belt from operating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.
Folding down the rear seatbacks will en-
large the luggage compartment. See
“—Stowage precautions” on page 305 in

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 maximum protection in a
frontal or rear collision when the
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.
After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.
After adjusting the seatback, push
your body back against the seat to
make sure the seat is locked in
position.
NOTICE
Do not fold the second seat seatback
forward with the luggage cover hooks
attached.
For easy access to the third seat, do
this.
1. Lift the lever on the side of the seat- back and fold the seatback.
The seat will slide forward.
2. Move the seat to the front −most posi-
tion.
After passengers are in, lift up the seat-
back and return the seat until it locks.
CAUTION
After putting back the seat, try push-
ing the seat forward and rearward to
make sure it is secured in place.
To fold down the second seat after it has
been moved to access the third seat,
push the seatback up slightly and then
pull the seatback adjusting lever before
folding the seatback down. (See “—Fold-
ing down second seats” described below
for instructions about folding down the
second seat.)
