Spark ignition system of your Toyota
The spark ignition system in your Toyota meets all re-
quirements of the Canadian InterferenceCausing Equip-
ment Standard.
Installation of a mobiletwoway radio system
As the installation of a mobile twoway radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system / sequential multiport fuel
injection system, cruise control system, antilock brake
system, SRS airbag system, seat belt pretensi oner sys-
tem and Toyota hybrid system, be sure to check with
your Toyota dealer for precautionary measures or special
instructions regarding installation.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in
your Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
CAUTION
When your vehicle or battery needs to be dis-
posed of, be sure to consult your Toyota dealer.
Hybrid vehicle batteries must be collected
through Toyota dealers. If your vehicle is dis-
posed of without dismantling, someone could
receive an electric shock by touching the high
voltage parts of the hybrid vehicle battery. If the
battery is not disposed of properly, its contents
can cause death or serious injury.

vi
CAUTION
If an accident occurs
Pull your Toyota off the road, put the selector le-
ver in “P” and remove the ignition key.
In order to avoid personal injuries, do not touch
any high voltage wirings and their connectors, and
high voltage parts (inverter unit, hybrid vehicle
battery, etc.).
If some exposed electric wirings are protruding in-
side or outside of your Toyota, an electric shock
may occur. Never touch the electric wirings.
If fluid leaks or gets in some parts of the vehicle,
never touch it because it may be electrolyte
(strong alkali) from the hybrid vehicle battery. If it
gets into your skin or eyes, wash off immediately
with a large amount of water, if possible, boric
acid solution, and get immediate medical attention
in order to help avoid serious injury.
If a vehicle fire occurs, extinguish it using a fire
extinguisher for the exclusive use on electric fires.
Or, use a large amount of water to prevent flam-
mable gas from being generated from the batteries.
When your Toyota needs to be towed, do it with
the front wheels raised. For details on towing, see
“If your vehicle needs to be towed” on page 182 in
Section 5.

Turn the ignition key from “ON” to
“START” with the running mode selector
lever in “P” position only. When the
“READY” light flashes and stays on and
a beep sounds after a few seconds, the
hybrid system starts. (If the ambient tem-
perature is low such as during winter con-
ditions, it may take time until the
“READY” light is on.) Being different from
ordinary vehicles, you cannot start your
vehicle with the running mode selector le-
ver in “N” position. (For details, see “How
to start the hybrid system—” on page 164
in Section 4.)Drive your vehicle with a smooth accel-
eration and deceleration.
When driving, energy is effectively re-
covered through the regenerative brake
as the vehicle decelerates. However,
for more efficient use, do not acceler-
ate or decelerate your vehicle more
than necessary.
By avoiding abrupt acceleration and de-
celeration, the remaining capacity of
the hybrid vehicle battery can be pre-
served and it makes it possible to run
the vehicle utilizing the gasoline engine
and the electric power from the hybrid
vehicle battery.
The remaining capacity of the hybrid
vehicle battery can be confirmed on
the energy monitor screen of the multi
information display. See “Information”
on 115 page in Section 26 for details.
As the way in which you drive may
decrease the remaining capacity of the
hybrid vehicle battery and reduce fuel
economy, drive your vehicle without
abrupt acceleration or deceleration.Use the “A/C” mode (with the “A/C”
button only on) when you use the air
conditioning.
As the gasoline engine starts and
stops automatically in this mode, eco-
nomical driving with less emissions is
possible.
In the “MAX” mode (with the “A/C” but-
ton and “MAX” button on), the gasoline
engine is frequently used. Use this
mode only when you need to operate
the air conditioning fully such as when
you should dehumidify or when you are
under a burning sun.
When parking, be sure to put the run-
ning mode selector lever in “P” posi-
tion. While driving, use “D” position.
With the selector lever in “N” position,
the gasoline engine operates but elec-
tricity cannot be generated. The
constant electrical power remaining in
the hybrid vehicle battery becomes in-
sufficient and the battery will be dis-
charged.

Do not touch the service plug.
The service plug is installed in the left
side trim of the trunk. It is provided to
shut out high voltage current of the hybrid
vehicle battery when the vehicle is in
need of repairs at a Toyota dealer.
CAUTION
The shaded parts in the illustration
are subjected to a high voltage.
Inappropriate handling may cause
an electric shock resulting in seri-
ous injury or death. Never touch
any item in shaded area.
Keep your hybrid vehicle’s driving char-
acteristics in mind.
As the vehicle runs with both the gaso-
line engine and electric motor, you may
hear a motor sound coming from the
engine compartment.
When the ignition switch is turned to
on or off, you may hear a sound com-
ing from the hybrid vehicle battery in
the trunk. However, this does not indi-
cate any trouble.
If the “READY” light is on, you can
start even with the gasoline engine
stopped.
When the hybrid vehicle battery tem-
perature is low or high, or the hybrid
vehicle battery capacity is decreased
with the selector lever at “R” during
driving, the output control warning light
comes on and the output might be lim-
ited for longer battery charge life.
If the output control warning light is on,
drive your vehicle without hard accel-
eration. The output power will be limit-
ed particularly when backing up.

14
When you put the running mode selec-
tor lever in “B” position and release
your foot from the accelerator pedal,
engine braking will be applied. Howev-
er, during the high speed driving you
may feel that deceleration by engine
braking is less than that of ordinary
vehicle.
Drive your vehicle without hard accel-
eration if the output control warning
light
() is on.
The hybrid vehicle battery temperature is
low or high, or the hybrid vehicle battery
capacity is decreased with the selector
lever at “R” during driving. If this occurs,
the output control warning light comes on.
If the output control warning light is on,
the hybrid system output is limited. Drive
your vehicle without hard acceleration.
Vehicle performance might be reduced sig-
nificantly especially when backing up.
Be sure to put the running mode selec-
tor lever in “P” position when parking.
With the selector lever in “N” position, the
hybrid vehicle battery assembly is not
charged, even if the gasoline engine is
operating. You cannot run your vehicle if
the selector lever is left in “N” position for
a long time because the hybrid vehicle
battery assembly will be discharged. When you leave your vehicle, apply the
parking brake with the running mode
selector lever in “P” position and be
sure to remove the key and lock all the
doors.
When you leave the the ignition key in the
“ACC” or “ON” position if the hybrid sys-
tem is not operating, the hybrid system
may not start because the auxiliary bat-
tery will be discharged.
CAUTION
When you leave your vehicle, be
sure to shut off the hybrid system.
Be sure to put the running mode
selector lever in “P” position be-
cause the vehicle can start with the
“READY” light on and the engine
stopped (no engine sound and
vibration). When the “READY” light
is on, if you leave your vehicle with
the running mode selector lever in
a position other than “P” and “N”,
the vehicle will creep and start
abruptly with the accelerator pedal
being depressed by mistake. It may
cause death or serious injury.
12p008a
If the multiinformation display shows
a message, the master warning light
() comes on in the instrument clus-
ter. Read the message and follow the
instruction.
When you leave your vehicle, or stop
or park for a while, put the selector
lever in “P”.
Charging is necessary. With the selec-
tor lever in “N” position, charging will
not be applied. The electric generator
operates in “P”, “D” or “B” position. If
you continue driving, put the selector
lever in “D” or “B” position and depress
the accelerator pedal. Do not leave it
in “N” position. When driving in traffic
jam, run in “D” position.

12p009c
Do not put the luggage on the package
tray behind the rear seatback.
An air vent is provided on the package
tray behind the rear seatback to cool
the hybrid vehicle battery. If this vent
is covered with something, the hybrid
vehicle battery will overheat resulting in
a reduction of the output performance
of the hybrid system.
Do not apply water or put foreign ob-
jects over the air vent. Otherwise, it
may affect the hybrid vehicle battery
adversely and cause damage.
You may hear a cooling fan noise from
the air vent.For vehicle repairs or maintenance, be
sure to consult your Toyota dealer.
If your vehicle is beyond repair because
of accident or something, be sure to
consult your Toyota dealer.
As sealed NickelMetal hydride batteries
are used, be sure to consult your Toyota
dealer when disposing of your vehicle.
CAUTION
If you are involved in an accident,
follow these precautions.
Move the vehicle to a safe place
and perform the followings to re-
duce the risk of high voltage elec-
tricity leakage.
 Depress the brake pedal and put the
selector lever in “P” position.
 Apply the parking brake.
 Turn the ignition switch to “LOCK”
and remove the key.
If your vehicle has experienced ma-
jor damage, you may get an electric
shock. To prevent this, never touch
the high voltage parts (hybrid ve-
hicle battery assembly, etc.) or
cables (orange color) connecting
these parts. If some exposed elec-
tric wiring is protruding inside or
outside of the vehicle, an electric
shock may also occur. Never touch
them.
If the fluid leaks or gets in some
part of the vehicle, never touch it
because it may be electrolyte
(strong alkali) from the hybrid ve-
hicle battery. If it gets on your skin
or eyes, wash off immediately with
a large amount of water, if possible,
with boric acid solution, and get
immediate medical attention in or-
der to help avoid serious injury.
If a vehicle fire occurs, extinguish
it using a fire extinguisher for the
exclusive use on electric fires. As
a small amount of water may be
dangerous, use a large amount of
water, for example from a fire hy-
drant, or wait for a firefighting
team arrival.

KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
If you should lose your keys or if you
need additional keys, duplicates can be
made by a Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.
21p006
The hybrid vehicle immobiliser system
is a theft prevention system. When you
insert the key in the ignition switch,
the transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The hybrid system will start, only
when the electronic code in the chip
corresponds to the registered ID code
for the vehicle.
21p007a
The system is automatically set when the
key is removed from the ignition switch.
The indicator light will start flashing to
show the system is set.
If either of the following indicator condi-
tions occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See ”Theft deterrent
system” on page 34 in this section.)
The indicator light does not start flash-
ing when the key is removed from the
ignition switch.
The indicator light flashes unsteady.

system

21
Inserting the registered key in the ignition
switch automatically cancels the system,
which enables the hybrid system to start.
The indicator light will go off.
For your Toyota dealer to make you a
new key with builtin transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the hybrid system.
NOTICE
Do not modify, remove or disas-
semble the hybrid vehicle immobiliser
system. If any unauthorized changes
or modifications are made, the proper
operation of the system cannot be
guaranteed.
