To use the armrest, pull it down as
shown above.
NOTICE
To prevent damage to the armrest,
avoid putting heavy loads on it.
To turn on the seat heater, push the
switch.
At this time, the indicator light will illu-
minate to indicate the seat heater is
operating.
The seat heater switches have the follow-
ing positions.
“HI”—High heating temperature
“LO”—Low heating temperature
The key must be in the “ON” position.
Pushing lightly on the opposite side will
turn it off.
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 handicapped
persons
Persons who have delicate 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.
 To prevent the battery from being
discharged, turn the switch off
when the engine is not running.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
for details.
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow the child to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. It does not provide sufficient
restraint.
Pregnant woman.
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.

CAUTION
Do not adjust the steering wheel
while the vehicle is moving. Doing
so may cause the driver to mishan-
dle the vehicle and an accident may
occur resulting in death or serious
injuries.
After adjusting the steering wheel,
try moving it up and down to make
sure it is locked in position.
Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side.
It is a convex mirror with a curved sur-
face. Any object seen in a convex mirror
will look smaller and farther away than
when seen in a flat mirror.
On some models, when you push the rear
window defogger switch, the heater panels
in the outside rear view mirrors will quick-
ly clear the mirror surface. (See “Rear
window and outside rear view mirror de-
foggers” in Section 14.)
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the
vehicle and an accident may occur
resulting in death or serious inju-
ries.
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is
on.
Outside rear view mirrors—

03 SIENNA_U (L/O 0207)
1342003 MY SIENNA (OM45410U)
To defog or defrost the rear window,
push the switch.
The key must be in the “ON” position.
The thin heater wires on the inside of the
rear window will quickly clear the window
surfaces. An indicator light will illuminate
to indicate the defogger is operating.
On some models, heater panels in the
outside rear view mirrors will also quickly
clear the surfaces.
Push the switch once again to turn the
defoggers off.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes.
CAUTION
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is on.
Make sure you turn the defoggers off
when the surfaces are clear. Leaving the
defoggers on for a long time could cause
the battery to discharge, especially during
stopandgo driving. The defoggers are
not designed for drying rain water or for
melting snow.If the outside rear view mirrors are heavi-
ly coated with ice, use a spray deicer
before operating the switch.
NOTICE
When cleaning the inside of the rear
window, be careful not to scratch or
damage the heater wires or connec-
tors.

The windows may be cleaned with any
household window cleaner.
NOTICE
When cleaning the inside of the rear

tors.
Air conditioning control panel, car au-
dio, instrument panel,
c onsole panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly
w ipe off dirt.
NOTICE
 Do not use organic substances (sol-
vents, kerosene, alcohol,
g asoline,
etc.) or alkaline or acidic solutions.
These chemicals can cause discol-
oring, staining or peeling of the
surface.
 If you use cleaners or polishing
agents, make sure their ingredients
do not include the substances men-
tioned above.
If you use a liquid car freshener, do
not spill the liquid onto the ve-
hicle’s interior surfaces. It may con-
tain the ingredients mentioned
a-
bove. Immediately clean any spill
using the method mentioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.
NOTICE
 If a stain should fail to come out
with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.
 Never use organic substances such
as benzine, alcohol or gasoline,
or
alkaline or acid solutions for clean-
ing the leather as these
could
c ause discoloring.
 Use of a nylon brush or synthetic
fiber cloth, etc. may scratch the
fine grained surface of the leather.
 Mildew may develop on soiled leath-
er upholstery. Be especially careful
to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight
may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.
