several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

curely to prevent fuel sp
illage in
the event of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It is designed
to regulate fuel tank pressure.

2004 SIENNA from Aug. ’04 Prod. (OM45422U)
Key off operation: If both front doors 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
opens half way, and the deflector stops
and raises fully.
If something gets caught between the
moon roof and frame during tilting
down operation, the moon roof stops
and opens 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 on the “TILT UP” side until
the moon roof tilts all the way up and
then tilts down a little automatically. 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 power window switches and
get trapped in a window. 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 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.
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.
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 front seats
equipped with side airbags. Such
changes may prevent the side air-
bags from activating correctly, dis-
able the system or cause the side
airbags to inflate accidentally, re-
sulting in death or serious injury.
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, 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
except for putting them in the auxil-
iary box. Otherwise, the objects
may interfere with the seatlock
mechanism or unexpectedly push
up the seat position adjusting lever
and the seat may suddenly move,
causing the driver to lose control of
the vehicle.
