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.

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 vehicle battery (regen-
erative brake).

Not in use
When stopping, the gasoline engine auto-
matically shuts off.
12p030b
Charging hybrid vehicle battery
When the hybrid vehicle battery power is
insufficient, the gasoline engine charges
the hybrid vehicle battery. The system al-
ways supplies electricity at a constant lev-
el.

Your vehicle is equipped with push but-
ton start. The hybrid system will start
automatically by pressing the “POWER”
switch briefly with the brake pedal de-
pressed.
Without smart function1. Insert the key.
2. Press 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.
The “READY” light flashes and stays on.
A beep sounds after a few seconds, and
the hybrid system will start. (If the ambi-
ent 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 230.)
The engine may not start even with the
“READY” light on. 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
vehicle battery can be confirmed on
the energy monitor screen of the multi
−
information display. See “Information”
on page 150 for details. Gradual or
non− abrupt acceleration or deceleration
will more effectively 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 vehicle battery
when the remaining battery power is
reduced. However, the charging is not
available if the hybrid transaxle is “N”.

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.

15
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 ve-
hicle battery assembly, etc.) or
cables (orange color) connecting
these parts. If some exposed elec-
tric wires are 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.
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 254.

UNLOCKING THE DOOR(S) WITH
SMART FUNCTION
The smart entry and start system can
be used to unlock the door(s) without
being inserted into the door keyhole.
When you get close to your vehicle (about
1 m (3 ft.) from each outside front door
handle), and are carrying the smart key,
the electronic code emitted from the key
is automatically checked to determine if it
corresponds to the registered ID code for
the vehicle. When you take hold of the
side back of the outside door handle sur-
face, it will unlock. At this time, two
beeps sound and the turn signal lights
flash twice.When you push and hold down the back
door opener switch, carrying the smart
key, the ID code is checked in the same
way as in the front door case. And all the
doors will unlock. At this time, two beeps
sound and the turn signal lights flash
twice.
When you get close to your vehicle (about
1 m or 3 ft. from either front door), carry-
ing the smart key or unlock the back door
using smart key function, the interior light
comes on for 15 seconds if the interior
light switch is in the “DOOR” position.
However, the interior lights go out when
you push the power door lock switch in
the lock position or press the “POWER”
switch once or twice from the off setting
to select the “ACC” or “IG
−ON” mode
without depressing the brake pedal. For
further information, see “Interior lights” on
page 107.
You have 30 seconds to open a door after
operating the smart unlocking function. If
a door is not opened by then, all the
doors will be automatically locked again.
INFORMATION
The rear doors are not equipped
with smart function.
When unlocking the door(s), be sure
to take hold of the back side of the
outside door handle firmly as
shown in the illustration. Taking
hold of the handle with a gloved
hand might cause a delay in unlock-
ing.
