SEATBACK ANGLE ADJUSTING STRAP
Lean forward and pull the strap for-
ward. Then lean back to the desired
angle and release the strap.
CAUTION
Align both seatbacks at the same
angle when a person sits in the
third seat center position. Other-
wise, the person cannot wear the
seat belt properly and this may
cause serious injuries in a collision.
Avoid reclining the seatback any
more than needed. The seat belts
provide maximum protection in a
frontal or rear collision when the
passengers are sitting up straight
and well back in the seats. If you
are reclined, the lap belt may slide
past your hips and apply restraint
forces directly to the abdomen or
your neck may contact the shoulder
belt. In the event of a frontal colli-
sion, the more the seat is reclined,
the greater the risk of death or per-
sonal injury.BEFORE STOWING THIRD SEATS1. Stow the third seat belt buckles as shown in the illustration.
This prevents the belt buckles from falling
out when you stow the third seat.
NOTICE
The seat belt buckles must be stowed
before you stow the third seat.
2. To stow the center seat belt, pull it slightly out of its cover. It will auto-
matically roll back partway. Roll the
seat belt backwards as shown above
and insert it into the slot of its cov-
er. Make sure the tabs are securely
locked in the cover.
NOTICE
The seat belt must be stowed before
you fold the seatback.

CAUTION
Do not sit on the third seat when it
is in the stowed position as shown in
the illustration. It may cause an acci-
dent or severe injury in the event of
emergency braking or collision.
CAUTION
When stowing or returning the seat,
observe the following precautions in
order to prevent personal injury:
Make sure the seat is free of people
or luggage. Then, hold the seat and
slowly move it. Otherwise, people
may be injured or luggage may be
damaged if the seat hits them.
Be careful not to get your hands or
feet pinched in the seat.
Do not stow and return the seats
when you are inside the vehicle in
order to prevent pinching your
hands or feet in the seat. Be sure
to stow and return the seats from
outside the vehicle.
When returning seats to their original
position, observe the following pre-
cautions in order to prevent personal
injury in a collision or sudden stop:
Make sure the seat is securely
locked by pushing forward and rear-
ward on the top of the seatback or
by trying to pull up the edge of the
bottom cushion. Failure to do so
will prevent the seat belt from oper-
ating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.

Idling for a long period with the air
conditioning on in stop−and− go traffic.
Towing a trailer.
It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
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 410 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.
It is not a malfunction even if the needle
of the tachometer returns to the bottom
position when the ignition switch is turned
to the “START” position.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

(b) Normal driving1. Start the engine as instructed in “How to start the engine” on page 394 in
Section 3. The transmission must be in
“P” or “N”.
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low, the transmis-
sion will not shift into the overdrive gear
even in the “D” position.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the “4” position. The trans-
mission will downshift to fourth gear
and engine braking will be enabled.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.
Tw o −wheel drive models
141 km/h (88 mph)
All −wheel drive models
137 km/h (86 mph)
Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.
Tw o −wheel drive models
91 km/h (57 mph)
All −wheel drive models
88 km/h (55 mph)
Shift into the “L” position. The trans-
mission will downshift to first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be en-
abled.
Tw o −wheel drive models
43 km/h (27 mph)
All −wheel drive models
42 km/h (26 mph)
Vehicles with cruise control or dynamic
laser cruise control—When the cruise con-
trol is being used, even if you downshift
from “D” to “4”, engine braking will not be
enabled because the cruise control is not
cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 192 or “Dy-
namic laser cruise control” on page 195
in this Section.

2004 SIENNA from Aug. ’04 Prod. (OM45422U)
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(d) Using “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ”3”, “2” or “L”,
you can start the vehicle in motion as
with the lever in “D”.
With the selector lever in “3” or “2”, the
vehicle will start in first gear and automat-
ically shift to third gear or second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
Twowheel drive models “3” 90 km/h (56 mph) . . . . . . . . . .
“2” 58 km/h (36 mph) . . . . . . . . . .
“L” 32 km/h (20 mph) . . . . . . . . . .
Allwheel drive models “3” 87 km/h (54 mph) . . . . . . . . . .
“2” 56 km/h (35 mph) . . . . . . . . . .
“L” 30 km/h (19 mph) . . . . . . . . . .
 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “4” position
should be used in hill climbing or
hard towing.
(e) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
Vehicles with rear view monitor system—
When the selector lever is shifted into “R”
position with the ignition switch in the
“ON” position, rear view monitor system
will activate. For instructions, see “Rear
view monitor system” on page 337 in Sec-
tion 1 −9.
(f) Parking 1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.

CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(g) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
shift the selector lever to the “4” posi-
tion. Be sure to shift the selector lever
to the “D” position immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use “D” position.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
(h) If you cannot shift the selector le-ver out of “P” position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift automatic transmission
selector lever” on page 429 in Section 4. The traction control system automatical-
ly helps prevent the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

Rapid acceleration/deceleration or
sharp turns is continue.
Towing a trailer.
The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Vehicles with the standard tires—
Adjust the tire pressure to the spe-
cified level as soon as possible.
Vehicles with the runflat tires—
Decelerate as soon as possible to
the lowest appropriate speed that
conditions permit. Do not drive for
longer than 160 km (100 miles) or
over 90 km/h (55 mph).
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
Note: The tire pressure warning sys-
tem on your vehicle will warn you
when one of your tires is significantly
underinflated and when some com-
binations of your tires are significant-
ly underinflated. However, there are
other combinations of significantly
underinflated tires for which your
tire pressure warning system may not
warm you. These other combinations
are relatively common, accounting for
approximately half the instances in
which vehicles have significantly un-
derinflated tires. For example, your
system may not warm you when both
tires on the same side or on the
same axle of your vehicle are signifi-
cantly underinflated. It is particularly
important, therefore, for you to check
the tire pressure in all of your tires
regularly and maintain proper pres-
sure.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system need
to be initialized in the following condi-
tions:
When the low tire pressure warning
light blinks twice every second
After replacing or rotating tires or
wheels
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard.
