Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The yellow warning light may stay on
for about 60 seconds after the hybrid
system is started. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red warning light and
buzzer. It is normal if the light turns off
and the buzzer stops sounding after a
few seconds.
You may hear a small sound in the
engine compartment after the hybrid
system is started or the brake pedal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem off.
The brake pedal stroke may be short
when you press the “POWER” switch
with the brake pedal depressed. (b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes and the buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
sounds 4 to 8 seconds.
If the vehicle speed rises above 20 km/h
(12 mph) without the belt fastened, a
buzzer sounds.
(c) Front Passenger ’s Seat Belt Reminder Light and Buzzer
This light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes if a passenger sits
in the front passenger seat and does not
fasten the seat belt. Unless the front pas-
senger fastens the belt, the light continues
flashing.
If the vehicle speed rises above 20 km/h
(12 mph) without the belt fastened, a
buzzer sounds. If luggage or other load is placed on the
front passenger seat, depending on its
weight, causing the reminder light to flash
and buzzer to sound.
(d) Malfunction Indicator Lamp
This lamp comes on when the “IGON”
mode is enabled and goes off after the
hybrid system starts. This means that
the warning light system is operating
properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following:
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
This case is a temporary malfunction. The
malfunction indicator lamp will go off after
taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota deal-
er as soon as possible.
There is a problem somewhere in the
engine, hybrid system, throttle control
system or warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.

129
Emissions inspection and maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (On−Board Diag-
nostics) system before taking your vehicle
for the inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 390.
(e) Master Warning Light
()
If the master warning light comes on, the
warning light for the faulty system is high-
lighted or the message such as “Please
press “P” to engage Park.” and “The bat-
teries will not be charged if the transaxle
is in Neutral N.” appears on the multi −in-
formation display. (See “Service reminder
indicators and warning buzzers— —Multi −
information display” on page 132 or “Pre-
cautions for use” on page 14 or “Fuel
gauge” on page 122 for instructions.) (f) “ABS” Warning Light
The light comes on when the “IG
−ON”
mode is enabled. If the anti −lock brake
system and the brake assist system work
properly, the light turns off after the
“READY” light comes on. Thereafter if the
system malfunctions, the light comes on
again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist system still operates.
In this case, the wheels could lock up
during a sudden braking or braking on
slippery road surfaces.
If any of the following conditions
occurs, this indicates a malfunction
somewhere in the parts monitored by
the warning light system. Contact your
Toyota dealer as soon as possible so
service the vehicle.
The light does not come on when the
“IG −ON” mode is enabled, or the light
remains on after the “READY” light
comes on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the red brake system
warning light, immediately stop your
vehicle at a safe place and contact
your Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Any of the following conditions may oc-
cur, but does not indicate the malfunc-
tion:
The light may stay on for about 60
seconds after the hybrid system is
started. It is normal if it turns off after
a whi l e.

(d) Using engine braking
To use engine braking, shift the shift lever
to “B” position.
During high speed driving, you may feel
that deceleration by engine braking is less
than that of a typical vehicle.
Do not continue normal driving with the
transaxle in “B” for a long time. This may
cause decreased fuel economy. To prevent
this, use “D” for normal driving.
When you shift the transaxle to “B” from
a position other than “D”, an alarm sounds
and the transaxle is automatically shifted
to “N”.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(e) Backing up1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the shift lever to the
“R” position. You will hear beeps while
the transaxle is in “R”.
When you shift the transaxle to “R” while
driving, an alarm sounds and the transaxle
is shifted to “N”.
(f) Parking 1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, push the “P” position switch.
If you press the “POWER” switch while
stopping, the transaxle is automatically
shifted to the “P” and the hybrid system
is turned off. If the driver ’s door is opened when the
transaxle is in “N”, “D” or “B”, beep
sounds and a warning message appears
on the multi
−information display to warn
you to shift the transaxle to “P”.
If you push the “P” position switch while
driving, an alarm sounds and the transaxle
is automatically shifted to “N”.NOTICE
Be sure to put the hybrid transaxle in
“P” when parking. In “N”, the hybrid
battery will not be charged even if the
gasoline engine is running. You can-
not start your vehicle if the transaxle
is left in “N” for a long time because
the hybrid battery will discharge.
When shifting the transaxle from “P” on
the slope, a large parking lock releasing
noise will be generated. However, this
does not indicate a malfunction.

(g) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, your vehicle is de-
signed like a typical automatic transmis-
sion vehicle which tends to move without
depressing the accelerator pedal with the
transaxle in a position other than “P” or
“N”.
With the transaxle in a position other than
“P” or “N”, depress the brake pedal firmly
even when stopped and apply the parking
brake as required.
When moving in a compact area or during
a traffic jam, it is an effective way to
control the speed using only the brake
pedal operation without depressing the ac-
celerator pedal.
Regenerative brake
When the accelerator pedal is released or
the brake pedal is depressed, the electric
motor acts as a generator and converts
kinetic energy to electric energy to provide
deceleration and recover electric energy to
charge the hybrid battery.
At this time, the electric motor running
noise may increase.The operation is the same as a typical
gasoline powered vehicle.
You may experience the following condi-
tion while braking. As they do not indicate
a malfunction, perform braking as usual:
In the “OFF” mode, pressing the
“POWER” switch once or twice will se-
lect “ACC” or “IG
−ON” only if the brake
pedal is not depressed. In this condi-
tion, the brake pedal may move a little.
Hybrid driving
This vehicle runs in combination with the
gasoline engine and electric motor.
If the “READY” light is on, you can start
your vehicle even with the gasoline engine
stopped. (h) If the system malfunctions
In the following conditions, there is some
problem in the system.
The indicator on the “P” position switch
flashes. However, this does not indi-
cate a malfunction unless a warning
message appears in the multi
−informa-
tion display.
All frames of shift position indicators in
the instrument cluster flash.
The parking system error message ap-
pears on the multi −information display.
The instrument cluster and multi −infor-
mation display does not come on when
the “IG −ON” mode is enabled.
In these cases, stop your vehicle in a
safe and level place, apply the parking
brake securely and contact your Toyota
dealer immediately.
(i) When the 12 volt battery is discon- nected
Before you disconnect the 12 volt battery,
confirm the shift position is “P” and apply
the parking brake completely.
After you reconnect the 12 volt battery,
shift the shift lever to “N” and confirm the
shift position is in “N” when the “IG −ON”
mode is enabled.

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1000 km (600 miles) can add
to the future economy and long life of
your vehicle:
Avoid full −throttle acceleration when
starting and driving.
Avoid racing the hybrid engine.
Try to avoid hard stops during the first
300 km (200 miles). FUEL TYPE
Your vehicle must use only unleaded
gasoline.
To help prevent gas station mixups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5
−M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
Select unleaded gasoline with an Oc-
tane Rating of 87 (Research Octane
Number 91) or higher. Use of unleaded fuel with an octane num-
ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline
that contains detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S.
contains detergent additives to keep clean
and/or clean intake systems.
Breakin period
Fuel

320
FUEL TANK CAPACITY45 L (11.9 gal., 9.9 lmp.gal.)
The given fuel tank capacity is measured
on EPA/CARB ORVR testing condition
which is approved for nominal capacity
measurement condition.
The fuel tank capacity is decreased at low
ambient temperature. (decreased by about
5 L (1.3 gal., 1.1 lmp.gal.) at −10 C
(14 F).)
Fuel pump shutoff system
The fuel pump shut −off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the hybrid system after the fuel
pump shut −off system activates, press the
“POWER” switch to the “OFF” mode and
start it.
CAUTION
Inspect the ground under the vehicle
before restarting the hybrid system. If
you find that liquid has leaked onto
the ground, the fuel system has been
damaged and it is in need of repair.
In this case, do not restart the hybrid
system.
If you plan to drive your Toyota in
another country...
First , comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

Electric water pumpCoolant heat storage
tank
Coolant flow control
valve
The coolant heat storage tank system
stores hot coolant and feeds it via the
electric water pump automatically to warm
the engine as required. This system helps
generate clean emissions. To confirm the
coolant heat storage system check, the
pump may operate automatically with the
vehicle stopped (in the “IG −OFF” mode).
Although the pump may operate and
cause noise while the vehicle is stopped,
this does not indicate a malfunction.
CAUTION
The coolant in this tank is hot even
if the engine and radiator are cold.
For replacement of the coolant,
contact your Toyota dealer.
Do not touch bolts (9 pieces)
painted in yellow.
In case the bolts are loosened,
there is a risk of hot coolant com-
ing out from inside the tank.
When this has any malfunction, the
surface of this tank gets hot. To
prevent burning yourself, do not
touch the tank.
INFORMATION
In such cases as the time of engine
starting and a short trip after the
engine is stopped, the electric water
pump will work for a moment, but
this is no problem.
This is for the preparation for good
emission.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs.
Do not adjust gaps for engine perfor-
mance or smooth drivability.
