If the engine is started during operating,
the seat operation may also be stopped.
If an object is caught between the seat
and floor, the object prevents the seat
from moving. Do not continue the op-
eration. Remove the object before oper-
ating the seat again.
If the indicator light above the switches
flashes even though there is no object
between the seatback and seat cushion,
contact your Toyota dealer.
CAUTION
When stowing 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. Be sure to operate the seats
from outside the vehicle.
When the indicator above the stowing
switch and returning switch come on
or flash, do not continue the opera-
tion. An object or a person may be
caught in the seat. If a person is
caught, serious injury may result.
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 ignition key in “ON” during the
operation. Doing so may cause the
vehicle to move and result in serious
personal injury.
NOTICE
Make sure that the seat path is clear
before stowing or returning the seat.
Otherwise, the seat cushion and seat
legs may be damaged if the seat
comes into contact with the luggage.
This “3RD SEAT” warning light warns the
third seat operation is not yet complete
when the ignition key is turned to the
“ON” position.

To turn on the seat heater, move the
dial upward (“L” dial for the left front
seat or “R” dial for the right front
seat). At this time, the indicator light
will illuminate to indicate the seat heat-
er is operating.
Move the dial upward or downward to ad-
just to the desired temperature.
To turn it off, move the dial downward
until it stops.
When the seat heater is not in use, move
the dial fully downward.
The key must be in the “ON” position to
operate seat heaters.
CAUTION
Occupants must use caution when op-
erating the seat heater because it
may make them feel too hot or cause
burns at low temperatures (erythema,
varicella). Use extra caution for;
Babies, small children, elderly per-
sons, sick persons or persons with
physical disabilities
Persons who have sensitive skin
Persons who are exhausted
Persons who have taken alcohol or
drugs which induce sleep (sleeping
drug, cold remedy, etc.)
To prevent the seat from overheating,
do not use the seat heater with a
blanket, cushion, or other insulating
objects which cover the seat.
NOTICE
 Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
 When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.

Low fuel level
warning light
Ty p e B
The gauge indicates the approximate
quantity of fuel remaining in the tank
when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
The needle moves when braking, acceler-
ating or making turns. This is caused by
the movement of the fuel in the tank.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

2006 SIENNA from March ‘06 Prod. (OM45443U)
The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop−and− go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 420 in
Section 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
