Spark ignition system of your Toyota
The spark ignition system in your Toyota meets all re-
quirements of the Canadian InterferenceCausing Equip-
ment Standard.
Installation of a mobiletwoway radio system
As the installation of a mobile twoway radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system / sequential multiport fuel
injection system, cruise control system, antilock brake
system, SRS airbag system, seat belt pretensi oner sys-
tem and Toyota hybrid system, be sure to check with
your Toyota dealer for precautionary measures or special
instructions regarding installation.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in
your Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
CAUTION
When your vehicle or battery needs to be dis-
posed of, be sure to consult your Toyota dealer.
Hybrid vehicle batteries must be collected
through Toyota dealers. If your vehicle is dis-
posed of without dismantling, someone could
receive an electric shock by touching the high
voltage parts of the hybrid vehicle battery. If the
battery is not disposed of properly, its contents
can cause death or serious injury.

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 (2 weeks or more),
the hybrid ve-
hicle battery and auxiliary battery will dis-
charge and their condition is liable to de-
cline. 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 com-
ponents turned off. 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.

operating condition

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 164
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 115 page in Section 26 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.

1. To open the fuel filler door, pull thelever up.
When refueling, turn off the hybrid
system.
CAUTION
Do not smoke, cause spark or allow
open flames when refueling. The
fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out the filler
neck if the cap is suddenly re-
moved.
Insert the fuel nozzle fully, or fuel
may splash out.

2. To remove the fuel tank cap, turnthe cap slowly counterclockwise,
then pause slightly before removing
it. After removing the cap, hang it
on the cap hanger.
It is not unusual to hear a slight swoosh
when the cap is opened. When insta lling,
turn the cap clockwise till you hear a
click.
If the cap is not tightened securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

CAUTION
Make sure the cap is tightened se-
curely to prevent fuel spillage in
case of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It is designed
to regulate fuel tank pressure.
