Toyota hybrid system combines a gaso-
line engine and electric motor power to
improve the fuel economy and minimize
the emissions as well as to provide
better power performance than the ordi-
nary gasolinepowered vehicles.
Depending on the driving condition, the
vehicle runs on the best combination of;
Gasoline engine power
Electric motor power generated by
the gasoline engine
Electric motor power of the hybrid
battery
Furthermore, the energy is efficiently used
in the following ways:
When stopping the vehicle, the gaso-
line engine is automatically stopped.
When applying the brakes or decelerat-
ing, electricity is converted from the
turning force of the wheels and stored
in the hybrid battery. (This is called
regenerative brake.)
Since the battery is charged by the
gasoline engine as needed, it does not
require charging from an outside
source like an electric vehicle. Basic operations are described below. Be-
sides, Toyota hybrid system performs vari-
ous controls depending on the operating
condition: The “Energy Monitor” screen
tells you which power is used currently.

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

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.

(a) Charging System Warning Light
When there are problems in the charging
system while the hybrid system is running,
the warning light comes on.
NOTICE
When the charging system warning
light comes on while the hybrid sys-
tem is running, malfunctions may
have occurred. If the warning light
comes on, immediately stop the ve-
hicle in a safe place and contact your
Toyota dealer.
(b) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it stays on while you are driving, pull
off the road to a safe place and stop the
engine immediately. Call a Toyota dealer
or qualified repair shop for assistance.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(c) High Coolant Temperature Warning Light
The light operates to warn that the hybrid
system is almost over heating.
If it comes on while you are driving, stop
the vehicle and check your hybrid system.
For detailed instructions, see “If your ve-
hicle overheats” on page 364.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
NOTICE
 Do not remove the thermostat in
the cooling system as this may
cause the hybrid system to over-
heat. The thermostat is designed to
control the flow of coolant to keep
the temperature of the hybrid sys-
tem within the specified operating
range.
 Continued driving with the light on
could result in the overheating of
hybrid system.

and then the positive cable.
12. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
13. If removed, replace all the battery vent plugs.
If the cause of your 12 volt battery dis-
charging is not apparent (for example,
lights left on), you should have it checked
at your Toyota dealer.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your hybrid
system in the normal way.
