Gasoline power
in use
During normal driving, the vehicle runs
mainly on gasoline power. However, the
electric motor, using electric power gener-
ated by the gasoline engine, can supple-
ment the gasoline engine power.
The vehicle controls the optimum ratio of
the gasoline and electric power to help
use energy more efficiently.
12p061b
Electric and gasoline
power in use
When driving at full throttle, additional
electric power is applied from the hybrid
battery. Vehicle performance improves.
12p062b
Storing electric power
When decreasing speed or applying the
brakes, the turning force of the wheels
makes the electric motor operate as a
generator and additional electricity is
stored in the hybrid battery (regenerative
brake).

12
12p063b
Not in use
When stopping, the gasoline engine auto-
matically shuts off.
12p064b
Charging hybrid battery
When the hybrid battery power is insuffi-
cient, the gasoline engine charges the hy-
brid battery. The system always supplies
electricity at a constant level. Your vehicle is equipped with push but-
ton start system. The hybrid system
will start automatically by pressing the
“POWER” switch briefly with the brake
pedal depressed.
With smart function
1. Carry the key with you.
2. Press the “POWER” switch briefly with the brake pedal depressed.
Without smart function
1. Insert the key.
2. Press the “POWER” switch briefly with the brake pedal depressed.
The “READY” light flashes and stays on.
Two beeps sound after a few seconds,
and the hybrid system will start. (If the
ambient temperature is low such as during
winter, it may take time until the “READY”
light comes on.) You cannot start your
vehicle when the brake pedal is not de-
pressed. (For details, see “How to start
the hybrid system—” on page 350.)
The engine may not start even with the
“READY” light on.
Starting your vehicle

13
Drive your vehicle with a smooth accel-
eration and deceleration.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for more
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.
Avoid abrupt acceleration and decelera-
tion.
The remaining capacity of the hybrid
battery can be confirmed on the energy
monitor screen of the multi−information
display. See “Information” on page 166
for details. Gradual or non −abrupt ac-
celeration or deceleration will more ef-
fectively use the benefits of an electric
motor without having to use gasoline
engine power. When parking, be sure to put the hy-
brid transaxle in “P”. While driving, use
the hybrid transaxle in “D”.
In “N”, the gasoline engine operates
but electricity cannot be generated. The
battery will be discharged requiring un-
necessary engine power to recharge.
The hybrid system automatically re-
charges the hybrid battery when the
remaining battery power is reduced.
However, the charging is not available
if the hybrid transaxle is “N”.
INFORMATION
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle is stopped.)
If the “READY” light remains on, you
can start your vehicle using the elec-
tric motor even with the gasoline en-
gine stopped.
The gasoline engine may not stop au-
tomatically in the following condi-
tions:
During gasoline engine warmup
During hybrid battery charging
During low or high hybrid battery
temperature
For efficient use of your
vehicle

14
The vehicle runs in combination with
the gasoline and electric power. Pay
special attention to the following items.
Be careful of high voltage and high
temperature.
Your vehicle is equipped with the orange
colored cables connected to the hybrid
battery (about 200 V) and to other compo-
nents that are all high voltage.
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.
An electric motor, coolant radiator and
some other parts reach high temperature
while driving. Caution labels are applied to
these parts. Carefully observe the instruc-
tions on these caution labels.
CAUTION
Never remove or disassemble any
high voltage part, high voltage cables
(orange color) and their connectors.
It may cause death or serious injury.

Do not touch the service plug.
The service plug is installed in the left
side trim of the luggage compartment. It
is provided to disable high voltage current
from the hybrid battery when the vehicle
is in need of repairs at your Toyota
dealer.
CAUTION
The shaded parts in the illustration
are subjected to high voltage.
Inappropriate handling may cause
an electric shock resulting in seri-
ous injury or death. Never touch
any item in shaded area.
These high voltage parts or cables
consisting of an electromagnetic
shielding structure produce relatively
the same amount of electromagnetic
waves as conventional gasoline
fueled vehicles or home electric ap-
pliances.
As unwanted noise may occur in the
reception of mobile radios, contact
your Toyota dealer for installation or
removal.
Always keep your hybrid vehicle’s driv-
ing characteristics in mind.
CAUTION
The driver should pay full attention
around the vehicle especially when it
is driven only by the electric motor
(with the gasoline engine stopped).
People in the immediate area might
misjudge the hybrid vehicle move-
ment based on the absence of the
regular engine noise.
Precautions for use

15

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 hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery in the luggage
compartment. However, this does not
indicate any trouble.
If the “READY” light is on, you can
start even though the gasoline engine
may be off.
When you shift the shift lever to “B”
and release it to its original position
and your foot from the accelerator ped-
al, engine braking will be applied. How-
ever, during high speed driving you
may feel that deceleration by engine
braking is less than that of ordinary
vehicle.
Be sure to put the hybrid transaxle in
“P” when parking.
In “N”, the hybrid battery assembly is not
charged, even if the gasoline engine is
operating. You cannot run your vehicle if
the hybrid transaxle is left in “N” for a
long time because the hybrid battery as-
sembly will be discharged. When you leave your vehicle, put the
hybrid transaxle in “P” and set the
parking brake. Be sure to carry the key
with you and lock all the doors.
If you leave the hybrid system in “ACC”
or “IG
−ON”, the hybrid system may not
start because the 12 volt battery will be
discharged.
If the vehicle is parked for a long time,
the hybrid battery will discharge gradually.
To keep the hybrid battery in good condi-
tion, drive the vehicle at least once every
several months for at least 30 minutes or
ten miles. If the hybrid battery becomes
fully discharged and the vehicle will not
start even with a jump −start to the 12 volt
battery, contact your Toyota dealer.
CAUTION
When you leave your vehicle, be
sure to shut off the hybrid system.
Be sure to put the hybrid transaxle
in “P” because 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 ve-
hicle in shift position other than
“P” and “N”, the vehicle will creep
and start abruptly with the accelera-
tor pedal being depressed by mis-
take. This may cause death or seri-
ous injury.

When the multiinformation display
shows this message, the master warn-
ing light
() comes on in the instru-
ment cluster. Read the message and
follow the instruction.
When you leave your vehicle, or stop
or park for a while, put the hybrid
transaxle in “P”.
Charging is necessary. In “N”, charging
will not be applied. The electric genera-
tor operates in “P”, “D” or “B”. If you
continue driving, put the hybrid trans-
axle in “D” or “B” and depress the
accelerator pedal. Do not leave the hy-
brid transaxle in “N”. When driving in
traffic jam, operate in “D”.
12P009d
Do not allow anyone to lean against the
side of the rear right seatback, nor put
any luggage or other obstructions on it.
An air vent is provided on the side of
the rear right seatback to cool the hy-
brid battery. If this vent is covered, the
hybrid battery will overheat resulting in
a reduction of the output performance
of the hybrid system.
The seat belt not properly set in the
guide on the top of the rear seat may
block the air vent. Be sure to pass the
seat belt through the guide properly.

17

Do not wet or put foreign objects over
the air vent. Otherwise, the hybrid bat-
tery may be adversely affected and be
damaged.
You may hear a cooling fan noise from
the air vent.
If water is used to wash the inside of
the vehicle or inside the luggage
compartment, or a large volume of wa-
ter is spilled in these areas, the hybrid
battery may be damaged, or a short
circuit may occur.
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 Nickel −Metal 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 apply
the parking brake.
 Press the “P” position switch and
stop the hybrid system.
 If the key is inserted into key slot,
remove it.
If your vehicle has experienced ma-
jor damage, you may get an electric
shock. To prevent this, never touch
the high voltage parts (hybrid bat-
tery assembly, etc.) or cables
(orange color) connecting these
parts. If some exposed electric
wires are protruding inside or out-
side 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 bat-
tery. 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 immedi-
ate 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. 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.
If your vehicle needs to be towed,
do it with the front wheels or all
four wheels raised. If the front
wheels are on the ground when
towing, the electric motor may con-
tinue to generate electricity which
could leak electricity. A fire could
occur depending on the degree of
damage. See “If your vehicle needs
to be towed” on page 376.

need one of them to make a new key
with a built −in transponder chip.
3. Mechanical keys (attached to the mas- ter keys)—These key work for the driv-
er ’s door only.
21P112
USING A MECHANICAL KEY
When you use the mechanical key in-
cluded on the side of the key, slide the
lock knob in the arrow direction and take
out the key as shown. To put the key
back, slide the lock knob in the arrow
direction and replace the key. Be sure to
put the key back when not in use.
Since the doors can be locked without a
key, you should always carry a spare
master key in case you accidentally lock
your keys inside the vehicle.
CAUTION
People with implanted pacemakers
or cardiac defibrillators s hould keep
away from the smart entry and start
system antennas, because the radio
waves may affect the operation of
such devices. For the antenna loca-
tions, see “ANTENNA LOCATIONS”
on page 26.
Users of any electrical medical de-
vice other than implanted pacemak-
ers and implanted cardiac defibrilla-
tors should consult the manufactur-
er of the device for information
about its operation under the influ-
ence of radio waves. Radio waves
could have unexpected effects on
the operation of such medical de-
vices.
If necessary, the smart function can
be disabled. See “DEACTIVATING
THE SMART FUNCTION” on page
34.
