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
vehicle 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 vehicle 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.
If you do not use the vehicle for a
long time (2 weeks or more), the hy-
brid vehicle battery and auxiliary battery
will discharge and their condition is li-
able to decline. Therefore, in order to
make up for discharging, charge them
once in every 2 weeks for about 30
minutes by starting the hybrid system
with all electrical components turned off.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.

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 electric
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions:
During gasoline engine warmup
 During hybrid vehicle battery charg-
ing
 During low or high hybrid vehicle
battery temperature 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
vehicle battery (about 200 V) and to other
components 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 vehicle battery when the
vehicle is in need of repairs at a 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.
Precautions for use

13
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.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid vehicle battery in the
luggage compartment. However, this
does not indicate any trouble.
As the vehicle runs with both the gaso-
line engine and electric motor, you may
hear a motor sound coming from the
engine compartment.
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 vehicle battery assembly
is not charged, even if the gasoline en-
gine is operating. You cannot run your
vehicle if the hybrid transaxle is left in “N”
for a long time because the hybrid vehicle
battery assembly will be discharged. When you leave your vehicle, apply the
parking brake to put the hybrid trans-
axle in “P” and 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 auxiliary battery will be
discharged.
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.

INFORMATION
When changing the mode, be sure
to push both “ ” (lock) and “ ”
(panic) buttons firmly, or panic
alarm may be activated.
 This operation will not change the
wireless remote control unlocking
function.
 In the single or driver’s door un-
locking mode, if you get into the
vehicle from the driver’s door carry-
ing the smart key, all the smart un-
locking controls activated by the
smart key will be stopped for secu-
rity. If you get out of the vehicle
from the driver’s door carrying the
smart key and get out of the effec-
tive range of the smart function,
unlocking control by the smart key
will be possible. However, unlocking
control may not be carried out for
5 seconds after you get out from
the vehicle. In this case, operate
unlock control again after 5 sec-
onds.
BATTERY POWER SAVING
When doors are locked, the smart entry
and start system transmits electromagnetic
waves to the outside of the vehicle at
regular intervals. For this reason, the ve-
hicle battery will be discharged if the ve-
hicle is left for a long time. If the key is
left within the effective range of the smart
function outside of the vehicle, the key
and the vehicle transmit electromagnetic
waves periodically. If these conditions con-
tinue for a long time, the battery in the
key and vehicle will be discharged.
To prevent the batteries from being dis-
charged, the smart function is automatical-
ly deactivated in the following conditions:
If there is no response from the key
for more than 14 days
If the key is left within the effective
range of the smart function outside of
the vehicle for more than 10 minutes To reactivate the smart function, perform
any of the following:
(a) Press the lock button on the outside front door handle or back door while
carrying the smart key.
(b) Perform a wireless remote control op- eration.
(c) Insert and turn the mechanical key in the keyhole of the driver’s door.
