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.

The hybrid system automatically con-
trols the level of electrical power re-
maining in the hybrid vehicle battery.
With the selector lever in a position
other than “N”, electricity is generated
and charging occurs when the level of
electrical power in the hybrid vehicle
battery decreases. It is unnecessary to
charge the hybrid vehicle battery from
outside.
INFORMATION:
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle stopped.)
If the “READY” light remains on, you
can start your vehicle using the electric
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions:
 During under gasoline engine warm
up
 During hybrid vehicle battery charg-
ing
 When the air conditioning is used in
the “MAX” mode, the gasoline engine
is frequently used. If the output control warning light ()
comes on in the instrument cluster, the
hybrid vehicle battery temperature is
low or high, or the hybrid vehicle bat-
tery capacity is decreased with the se-
lector lever at “R” during driving. As it
does not indicate the failure of the sys-
tem, you can continue driving but avoid
hard acceleration because the power is
insufficient (which is caused by the bat-
tery power deterioration).
The vehicle runs in combination with
the gasoline and electric power. Pay
special attention to the following items.
Be careful of a high voltage and high
temperature.
Your vehicle is equipped with the orange
colored cables connected to the hybrid
vehicle battery which contain a high volt-
age (about 300 V) and to other high volt-
age parts.
CAUTION
Do not touch or come in contact with
orange cables or battery terminals.
Electric shock may cause serious in-
jury or death. Read all caution labels.
A electric motor, coolant radiator and
some other parts reach high temperature
when you are driving. Caution labels are
applied to these parts. Carefully observe
the instructions on these caution labels.
10.Precautions for use

13
CAUTION
Never remove or disassemble the
high voltage parts, high voltage
cables (orange color) and their con-
nectors. It may cause death or seri-
ous injury.

plug
High volt-
age cables
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.

21p003a
When starting the hybrid system,
do not use the key in proximity
with other transponder keys (includ-
ing keys of other vehicles) and do
not press other key plates against
the key grip. Doing so may prevent
the hybrid system from starting or,
may cause the hybrid system to
stop soon after it starts. If this hap-
pens, remove the key once and
then insert it again after taking off
other transponder keys (including
keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
hybrid system.
21p004a
Do not bend the key grip.
Do not cover the key grip with any
material that cuts off electromagnet-
ic waves.
 Do not knock the key hard against
other objects.
 Do not leave the key exposed to
high temperatures for a long period,
such as on the dashboard or hood
under direct sunlight.
 Do not put the key in water or
wash it in an ultrasonic washer.
 Do not use the key with electromag-
netic materials.

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.
