The hybrid system automatically con-
trols the level of electrical power re-
maining in the hybrid vehicle battery.
With the selector lever in a position
other than “N”, electricity is generated
and charging occurs when the level of
electrical power in the hybrid vehicle
battery decreases. It is unnecessary to
charge the hybrid vehicle battery from
outside.
INFORMATION:
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle 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 under gasoline engine warm
up
 During hybrid vehicle battery charg-
ing
 When the air conditioning is used in
the “MAX” mode, the gasoline engine
is frequently used. If the output control warning light ()
comes on in the instrument cluster, the
hybrid vehicle battery temperature is
low or high, or the hybrid vehicle bat-
tery capacity is decreased with the se-
lector lever at “R” during driving. As it
does not indicate the failure of the sys-
tem, you can continue driving but avoid
hard acceleration because the power is
insufficient (which is caused by the bat-
tery power deterioration).
The vehicle runs in combination with
the gasoline and electric power. Pay
special attention to the following items.
Be careful of a high voltage and high
temperature.
Your vehicle is equipped with the orange
colored cables connected to the hybrid
vehicle battery which contain a high volt-
age (about 300 V) and to other high volt-
age parts.
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.
A electric motor, coolant radiator and
some other parts reach high temperature
when you are driving. Caution labels are
applied to these parts. Carefully observe
the instructions on these caution labels.
10.Precautions for use

13
CAUTION
Never remove or disassemble the
high voltage parts, high voltage
cables (orange color) and their con-
nectors. It may cause death or seri-
ous injury.

Inverter unitHybrid vehicle battery
Service
plug
High volt-
age cables
Do not touch the service plug.
The service plug is installed in the left
side trim of the trunk. It is provided to
shut out high voltage current of 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 a high voltage.
Inappropriate handling may cause
an electric shock resulting in seri-
ous injury or death. Never touch
any item in shaded area.
Keep your hybrid vehicle’s driving char-
acteristics in mind.
As the vehicle runs with both the gaso-
line engine and electric motor, you may
hear a motor sound coming from the
engine compartment.
When the ignition switch is turned to
on or off, you may hear a sound com-
ing from the hybrid vehicle battery in
the trunk. However, this does not indi-
cate any trouble.
If the “READY” light is on, you can
start even with the gasoline engine
stopped.
When the hybrid vehicle battery tem-
perature is low or high, or the hybrid
vehicle battery capacity is decreased
with the selector lever at “R” during
driving, the output control warning light
comes on and the output might be lim-
ited for longer battery charge life.
If the output control warning light is on,
drive your vehicle without hard accel-
eration. The output power will be limit-
ed particularly when backing up.

14
When you put the running mode selec-
tor lever in “B” position and release
your foot from the accelerator pedal,
engine braking will be applied. Howev-
er, during the high speed driving you
may feel that deceleration by engine
braking is less than that of ordinary
vehicle.
Drive your vehicle without hard accel-
eration if the output control warning
light
() is on.
The hybrid vehicle battery temperature is
low or high, or the hybrid vehicle battery
capacity is decreased with the selector
lever at “R” during driving. If this occurs,
the output control warning light comes on.
If the output control warning light is on,
the hybrid system output is limited. Drive
your vehicle without hard acceleration.
Vehicle performance might be reduced sig-
nificantly especially when backing up.
Be sure to put the running mode selec-
tor lever in “P” position when parking.
With the selector lever in “N” position, the
hybrid vehicle battery assembly is not
charged, even if the gasoline engine is
operating. You cannot run your vehicle if
the selector lever is left in “N” position for
a long time because the hybrid vehicle
battery assembly will be discharged. When you leave your vehicle, apply the
parking brake with the running mode
selector lever in “P” position and be
sure to remove the key and lock all the
doors.
When you leave the the ignition key in the
“ACC” or “ON” position if the hybrid sys-
tem is not operating, the hybrid system
may not start because the auxiliary bat-
tery will be discharged.
CAUTION
When you leave your vehicle, be
sure to shut off the hybrid system.
Be sure to put the running mode
selector lever in “P” position be-
cause 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 vehicle with
the running mode selector lever in
a position other than “P” and “N”,
the vehicle will creep and start
abruptly with the accelerator pedal
being depressed by mistake. It may
cause death or serious injury.
12p008a
If the multiinformation display shows
a message, the master warning light
() comes on in the instrument clus-
ter. Read the message and follow the
instruction.
When you leave your vehicle, or stop
or park for a while, put the selector
lever in “P”.
Charging is necessary. With the selec-
tor lever in “N” position, charging will
not be applied. The electric generator
operates in “P”, “D” or “B” position. If
you continue driving, put the selector
lever in “D” or “B” position and depress
the accelerator pedal. Do not leave it
in “N” position. When driving in traffic
jam, run in “D” position.

If you lose your transmitter, contact your
Toyota dealer as soon as possible to
avoid the possibility of theft, or an acci-
dent. (See “If you lose your wireless re-
mote control transmitter” on page 189 in
Section 5.)

22p010
This indicator comes on when the igni-
tion key is turned to the “ACC” or
“ON” position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, warning light, in-
terconnecting wiring and power sources.
(For details, see “Service reminder indica-
tors and warning buzzers” on page 93 in
Section 24.)
22p011
The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor. When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smokelike
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repairs and modifications.
