(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
When the regenerative brake system
is fails...
When the hydraulic brake booster
fails...
If the hydraulic booster causes a problem
resulting in poor braking performance, the
warning light comes on and buzzer sounds
continuously. Have your vehicle checked at your
Toyota dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If any of the following conditions oc-
curs, immediately stop your vehicle at
a safe place and contact your Toyota
dealer.
The light does not turn off even
after the parking brake is released
while the hybrid system is running.
The warning buzzer comes on to-
gether with the warning light.
In either case, this can indicate that
the brakes may not work properly and
your stopping distance will become
longer. Depress the brake pedal firmly
and bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
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 do not indicate the malfunc-
tion:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the 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 p edal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.

(a) Power Steering System WarningLight
This light comes on when the power
steering control system fails.
If the vehicle starts moving on the decline
before the ignition is turned on, turning
the ignition switch to “ON” will light up
this light. At this time, you may feel the
steering wheel heavy.
If this occurs, stop your vehicle complete-
ly, turn the ignition switch to “ACC” or
“LOCK” and start the hybrid system again.
CAUTION
If this light comes on, take your ve-
hicle to the Toyota dealer as soon as
possible. In this case, you may feel
the heavy steering wheel maneuver-
ing. Drive your vehicle while gripping
the steering wheel firmly.
(b) Hybrid Vehicle Battery Warning Light
This light comes on in the following
cases.
a. The hybrid vehicle battery voltage
drops with the running mode selector lever
left in “N” position.
The system works properly if you put the
running mode selector lever to “P” position
and the light goes off.
b. The fuel tank is completely empty. (See
“Fuel gauge” in this section for instruc-
tions.)
c. The hybrid vehicle battery is dis-
charged.
If this light comes on with the “READY”
light on in case of c., stop your vehicle
in a safe place and contact your Toyota
dealer. (c) Hybrid System Warning Light ()
This light comes on if there is a problem
in the electric motor, inverter unit, hybrid
vehicle battery, etc.
If this light is on, stop your vehicle in a
safe place immediately and contact your
Toyota dealer.
Even if the hybrid system warning light
comes on, you could increase the speed
a little temporarily by depressing the ac-
celerator pedal. Immediately pull up your
vehicle at a safe place and contact your
Toyota dealer.

(b) Normal driving1. Start the hybrid system as instructed in ”How to start the hybrid system” on
page 166 in Section 4. The transmis-
sion must be in ”P”.
2. With your foot holding down the brake pedal, shift the selector lever to ”D”.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
25p004b
(c) Using engine braking
To use engine braking, shift the selector
lever to “B” position.
During high speed driving, you may feel
that deceleration by engine braking is
smaller than that of ordinary vehicle.
Do not continue normal driving with the
selector lever in “B” position for a long
time. This may cause decreased fuel
economy. To prevent this, use “D” position
for normal driving.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(e) 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, shift the selector lever to the “P” posi-
tion.

108
If the driver ’s door is opened when the
the “READY” light is on and the the selec-
tor lever is at a position other than “P”
with the parking brake applied, you will
hear beeps to warn you to shift the selec-
tor lever to the “P” position.
CAUTION
While the vehicle is moving, never
attempt to move the running mode
selector lever into “P” position under
any circumstances. Serious mechani-
cal damage and loss of vehicle con-
trol may result.
NOTICE
Be sure to put the selector lever in
“P” position when parking. With the
selector lever in “N” position, the hy-
brid vehicle battery will not be
charged even the gasoline engine op-
erates. You cannot start your vehicle
if the selector lever is left in “N”
position for a long time because the
hybrid vehicle battery will discharge.
(f) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, vehicle is designed
like an ordinary automatic transmission
vehicle which tends to move without de-
pressing the accelerator pedal with the
selector lever in a position other than “P”
or “N”.
With the selector lever 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 restricted area or dur-
ing 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 the electric ener-
gy to charge the hybrid vehicle battery.
At this time, the electric motor running
noise becomes larger.The operation is the same as an ordinary
gasoline powered vehicle.
You may experience the following condi-
tions while braking. As they do not indi-
cate the malfunction, perform braking as
usual:
When you turn the ignition switch to
“ON” with the brake pedal depressed,
you may feel a little push from the
brake pedal.
When you turn the ignition switch to
“ACC” or “LOCK” from “ON”, the brake
pedal may move a little.

109
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.
When the hybrid vehicle battery tempera-
ture is low or high, or the hybrid vehicle
battery capacity is decreased with the run-
ning mode selector lever at “R” during
driving, the output control warning light is
on and the output power may be limited.
If the output control warning light is on,
drive your vehicle without hard accelera-
tion. The output power will be limited par-
ticularly when backing up.
(g) If you cannot shift lever out of “P”position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift running mode selector
lever” on page 188 in Section 5.

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal while depressing the brake pedal.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Driving with the parking brake en-
gaged can reduce braking power.
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.

3. Powerful cooling and dehumidifying
If the air conditioning does not work well
with the “A/C” button on, push the “MAX”
button. To cancel the “MAX” mode, push
the “MAX” button again. To turn off the air
conditioning, push the “A/C” button.
With the “MAX” button on, the gasoline
engine is frequently used.
The air conditioning may not turn on with
the selector lever in “N” position because
the gasoline engine cannot start.
If the “A/C” button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to your Toyota dealer for service. For economical and environmentfriend-
ly use
Usually, use the air conditioning with the
“A/C” button on (economical and environ-
mentfriendly cooling).
In this mode the gasoline engine starts
and stops automatically and good fuel
economy driving is achieved.
To use the air conditioning in economi-
cal and environmentfriendly way, we
recommend the following setting:
1. Lower the setting temperature if you feel a little hot with the “A/C” button
on.
2. If you feel still hot with the “A/C” but- ton on, push the “MAX” button also.
After the compartment cools, turn off
the “MAX” mode only.

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
breakin. 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 fullthrottle 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 To-
yota has a smaller fuel tank opening.
The
special nozzle on pumps with unleaded fuel
will fit it, but the larger standard 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 3.5M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its
effectiveness and the emission con-
trol 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 build
up of engine deposits.
However, all gasoline sold in the U.S. con-
tains detergent additives
to keep clean and/or
clean intake systems.

106.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).)
107.Fuel pump shutoff system
The fuel pump shutoff 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 shutoff system activates, turn the
ignition switch to “ACC” or “LOCK” once
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).
