Toyota hybrid system combines the
gasoline engine and the electric motor
power to improve the fuel economy
largely and minimize the emissions as
well as to provide higher power perfor-
mance than the ordinary gasolinepow-
ered 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 effectively used
in the following ways:
When stopping the vehicle, the gaso-
line engine is automatically stopped.
When decreasing the speed by apply-
ing the brakes, electricity converted
from the turning force of the wheels is
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 the outside like
an electric vehicle.
In this way, greatly improved fuel economy
and reduced emissions are attained.
If you do not use the vehicle for a long
time, the hybrid vehicle battery will dis-
charge and the battery condition is liable
to decline.
Basic operations are described below. Be-
sides, Toyota hybrid system performs vari-
ous controls depending on the operating
condition, such as at the time of hybrid
system starting, at the time of charging
should be required, at the time of the air
conditioning is in use, etc.

Electric power
in use
When starting or backing up, etc., the
gasoline engine efficiency worsens, so
the vehicle runs on electric power from
hybrid vehicle battery.
12p017a
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, makes up for
any deficiency of gasoline power.
The vehicle controls the optimum ratio of
the gasoline and electric power to help
save energy more effectively.
12p018a
Electric and gasoline
power in use
When driving at full throttle, electric
power is further applied from the hybrid
vehicle battery. Vehicle performance impro-
ves.

12p019a
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).
12p020a
Not in use
When stopping, the gasoline engine auto-
matically shuts off.
12p030
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.

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 162
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 113 page in Section 2 −6 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.
