The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire pressure is
low, or it may come on when the tire
pressure is actually normal.
The tread wear is uneven among the
installed tires.
A compact spare tire, snow tires, or
tire chains are used.
The tire pressure is excessively higher
than specified, or tire pressure is sud-
denly reduced due to bursts or other
causes.
The vehicle is driven on a slippery
road surface such as rough road and
frozen road.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
Pushing this reset switch after replac-
ing or rotating tires or wheels memo-
ries the present tire condition as a
standard.
After replacing or rotating the tires or
wheels, perform the initial adjustment as
follows.1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust pressures of all the installed tires to the specified level. (See “Tires”
in Section 8.)
3. Turn the ignition key to “ON”. 4. With the vehicle stopped, push the re-
set switch on the left lower instrument
panel and hold it until the low tire
pressure warning light blinks for three
times.
5. The initial adjustment is completed af- ter driving at the speeds of 30 km/h
(19 mph) or over for about total 8
hours, when the tire pressure warning
system detects the normal tire pressur-
es.
Do not push the reset switch without ad-
justing the tire pressure to the specified
level. Otherwise, the low tire pressure
warning light may not come on even if the
tire pressure is low, or it may come on
when the tire pressure is actually normal.
If you push the reset switch while the
vehicle is moving, the initial adjustment is
not performed.
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.

Ty p e A
Ty p e B
When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.

TURNING ON THE SYSTEM
To operate the cruise control, press the
“CRUISE ONOFF” button. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another press will turn the system
completely off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the “CRUISE ON
OFF” switch off when not using the
cruise control.
SETTING AT A DESIRED SPEED
The transmission must be in “D” before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the “SET/COAST”
direction and release it. This sets the ve-
hicle at that speed. If the speed is not
satisfactory, tap the lever up for a faster
speed, or tap it down for a slower speed.
Each tap changes the set speed by 1.6
km/h (1.0 mph). You can now take your
foot off the accelerator pedal.If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the “CANCEL” di-
rection and releasing it.
b.
Depressing the brake pedal.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.

1602003 MY SIENNA (OM45410U)
RESETTING TO A FASTER SPEED
Push the lever up in the “RES/ACC” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will gradually
gain speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “SET/COAST” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “SET/COAST”
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speed
will gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “SET/COAST” direction.
Even if you turn off the overdrive switch,
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. To decrease the
vehicle speed, reset to a slower speed
with the cruise control lever or depress
the brake pedal. If you use the brake
pedal, cruise control is cancelled.RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal, pushing the lever up in the
“RES/ACC” direction will restore the speed
set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “CRUISE ON
OFF” button to turn the system off and
then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

NOTICE
To ensure correct audio system op-
erations:
Be careful not to spill beverages
over the audio system.
 Do not put anything other than a
cassette tape or Compact Disc into
the slot.
 The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio system which you are listening
to. However, this does not indicate
a malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as your vehicle moves. Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations—Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multipath—FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.
Static and fluttering—These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping—If the FM signal you
are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the origi-
nal signal can be picked up again.
AM
Fading—AM broadcasts are reflected by
the upper atmosphere—especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound
alternately strong and weak.
Station interference—When a reflected sig-
nal and a signal received directly from a
radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static—AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)

Use highquality cassettes.
Lowquality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant autoreversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS
Your compact disc player is intended
for use with 12 cm (4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning
to cool the vehicle interior before you
listen to a disc.
Bumpy roads or other vibrations may
make your compact disc player skip.
If moisture gets into your compact disc
player, you may not hear any sound
even though your compact disc player
appears to be working. Remove the
disc from the player and wait until it
dries.
CAUTION
Compact disc players use an invisible
laser beam which could cause hazard-
ous radiation exposure if directed
outside the unit. Be sure to operate
the player correctly.
Use only compact discs marked as
shown above. CDR (CDRecordable),
CDRW (CDRewritable) and personal
computer use CDROMs may not be
playable on your compact disc player.

Labeled discs
NOTICE
To prevent damage to the changer or
player, do not use special shaped, low
quality or labeled discs such as those
shown in the illustrations.
CorrectWrong
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the
disc up to the light.)
Remove discs from the compact disc
player when you are not listening to
them. Store them in their plastic cases
away from moisture, heat, and direct
sunlight.
