“START”—The hybrid system is ready
to operate.
Turn the key to the “START” position and
hold the ignition switch at this position for
about a few seconds until the “READY”
light comes on and a beep sounds. (If the
ambient temperature is low such as during
winter conditions, it may take time until
the “READY” light is on.” The key will
return to the “ON” position when released.
Being different from ordinary vehicles, you
cannot start your vehicle with the running
mode selector lever in “N” position.
“ON”—The hybrid system starts to run
when the accelerator pedal is depressed
with the “READY” light and all accesso-
ries on.This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the hybrid system is off.
If you leave your key in the “ACC” posi-
tion for a while, put the running mode
selector lever in “P” position.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.
“LOCK”—The hybrid system is off and
the steering wheel is locked. The key
can be removed only at this position.
You must push in the key to turn it from
“ACC” to the “LOCK” position. The selec-
tor lever must be put in the “P” position
before pushing the key.
Vehicles with hybrid vehicle immobiliser
system–Once you remove the key, the hy-
brid vehicle immobiliser system is auto-
matically set. (See “Hybrid vehicle immobi-
liser system” on page 20 in Section 2
−1.)
When starting the hybrid system, the key
may seem stuck at the “LOCK” position.
To free it, first be sure the key is pushed
all the way in, and then rock the steering
wheel slightly while turning the key gently.
NOTICE
Do not leave the key in the “ACC” or
“ON” position for a long time when
the hybrid system is off. The auxiliary
battery will discharge.

Hybrid transaxle
Your hybrid transaxle has a shift lock sys-
tem to minimize the possibility of incorrect
operation. This means you can only shift
out of “P” position when the brake pedal
is depressed (with the ignition switch in
“ON” position and the lock release button
depressed).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.
P:Parking, hybrid system starting and
key removal position
R: Reverse position
N: Neutral position
D: Normal driving position
B: Engine braking position
When the cruise control is being used
even if you shift the selector lever to “B”
position, engine braking will not be applied
because the cruise control is not can-
celled. For ways to decrease the vehicle
speed, see “Cruise control” on page 107.

“ON”, the initial “TOYOTA” screen appears
and the system begins operating.
After a few seconds, the previous mode
display will appear.
If the electrical power source has been
disconnected from the multi−information
display, the display will be automatically
set to the initial mode.
CAUTION
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.
Switch operation
This system operates mainly by the
switches on the screen. To protect the
screen, lightly touch switches on the
screen with your finger. When you touch
a switch on the screen or on the bezel,
a beep sounds.
If the system does not respond to a
touch of a switch, move your finger
away from the screen and then touch
it again.
You cannot operate dimmed switches.
Wipe off fingerprints on the surface of
the display using a glass cleaning
cloth.

information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR” to turn the audio system on
and off.
Push “AUDIO” to display switches for au-
dio system.
Push “AM”, “FM” or “TAPE” to turn on that
function without pushing “PWR”.
You can turn on each player by inserting
a cassette tape.
You can turn off each player by ejecting
the cassette tape. If the audio system was
previously off, then the entire audio sys-
tem will be turned off when you eject the
cassette tape. If another function was pre-
viously playing, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM” or “TAPE” if the system
is already on but you want to switch from
one function to another.VOLUME CONTROL
To adjust the volume, turn the “VOL”.

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, 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).

1. Threeway catalytic converter
2. Toyota HC adsorber and catalyst sys-tem
The threeway catalytic converter and
Toyota HC adsorber and catalyst system
are emission control devices installed
in the exhaust system.
Its purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases
flowing into the threeway catalytic
converter and Toyota HC adsorber
and catalyst system may cause it to
overheat and create a fire hazard. To
prevent this and other damage, ob-
serve the following precautions:
 Use only unleaded gasoline.
 Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three
way catalytic converter and Toyota
HC adsorber and catalyst system.
 Do not turn off the ignition while
the vehicle is moving.
 Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high temperature of three
way catalytic converter and Toyota
HC adsorber and catalyst system.

HYDRAULIC BRAKE
This brake system has 2 independent hy-
draulic circuits. If either circuit should fail,
the other will still work. However, the ped-
al will be harder to press, and your stop-
ping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sounds continuous-
ly. In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er. The brake system warning light may stay
on for about 60 seconds after the ignition
key is turned to the “ON” position. It is
normal if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the brake system 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.
CAUTION
Do not pump the brake pedal if the
hybrid system is not operating.
Each push on the pedal uses up
your reserved brake fluid pressure.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
be longer.
ANTILOCK BRAKE SYSTEM
The antilock brake system is designed
to automatically help prevent lockup of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing directional stab
ility
and steering performance of the vehicle
under these circumstances.
Effective way to press the ABS brake
pedal: When the anti −lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti −lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking perfor-
mance.
The anti −lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).

“ABS” warning light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system works prop-
erly, the light turns off after a few sec-
onds. Thereafter, if the system malfunc-
tions, 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
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the parts monitored by the
warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains 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 brake system warn-
ing light, immediately stop your ve-
hicle 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.
Either of the following conditions may
occur, but does not indicate the mal-
function:
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 light. It is normal if
it turns off after a few seconds.

1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, head restraint height and steering
wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
When you get in the vehicle, check
whether the “READY” light is on or
not.
CAUTION
Your vehicle does not produce any
noise or vibration when the vehicle is
ready to start with the “READY” light
on. Be careful not to start the vehicle
abruptly by depressing the accelera-
tor pedal inadvertently.

Before starting the hybrid system, be sure
to follow the instructions in “(a) Before
starting the hybrid system”.
Normal starting procedure
Turn and hold the ignition switch to
“START” with the brake pedal depressed.
The “READY” light starts blinking. After a
few seconds, the blinking “READY” light
remains on and a beep sounds. (If the
ambient temperature is low, such as dur-
ing winter driving conditions, it may take
time until the “READY” light is on.) Then
release your hand from the ignition switch.

When the ignition switch is turned to on
or off, you may hear a sound coming from
the hybrid vehicle battery in the trunk.
However, this does not indicate any
trouble.
NOTICE
The “READY” light does not come on
when the selector lever is put in a
position other than “P”. Depress the
brake pedal and put the selector lever
in “P” and turn the ignition switch to
“START” again.
If there is a problem somewhere in the
hybrid system, the hybrid system malfunc-
tion warning light will come on in place of
the “READY” light. If this happens, contact
Toyota dealer.
NOTICE
When you start the hybrid system at
a lowered outside temperature, it may
take longer before the blinking
“READY” light changes to stay on.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp−edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and put the selector le-
ver into “P”. If necessary, block the
wheels.
Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake pulled. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
CAUTION
Before driving off, make sure the
parking brake is fully released and
that the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended with the “READY” light on.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating or
braking on a slippery surface. Sud-
den acceleration or engine braking,
could cause the vehicle to spin or
skid.
