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 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.

This section describes some of the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR·VOL” to turn the audio system
on and off.
Push “AM”, “FM1·2”, “TAPE” or “CD” to
turn on that function without pushing
“PWR·VOL”.
You can turn on each player by inserting
a cassette tape or compact disc.
You can turn off each player by ejecting
the cassette tape or compact disc. If the
audio system was previously off, then the
entire audio system will be turned off
when you eject the cassette tape or com-
pact disc. If the another function was pre-
viously playing, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM1·2”, “TAPE” or “CD” if the
system is already on but you want to
switch from one function to another.TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.
YOUR RADIO ANTENNA
Mast type antenna—To remove an anten-
na, carefully turn it counterclockwise.
NOTICE

Mast type antenna:
To prevent damage to the antenna,
make sure it is removed before
driving your Toyota through an au-
tomatic car wash.
 Onglass antenna (builtin on the
rear window glass):
Attaching the film (especially con-
ductive or metallic type) on the rear
glass will noticeably reduce the
sensitivity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
