If manual onoff of the air conditioning
is desired—
Touch the “A/C” switch to turn the air
conditioning on and touch it again to turn
the air conditioning off.
If the system is used for ventilation, heat-
ing in dry weather or removing frost or
exterior fog on the windshield, turn the air
conditioning off once it is no longer re-
quired. This will improve fuel economy.
The air conditioning can be used for year−
round automatic temperature control in-
cluding cooling and dehumidifying opera-
tion.

To remove interior fog on the wind-
shield—
Touch the front windshield switch.
To remove frost or exterior fog on the
windshield— 1. Touch the upper side of the tempera- ture control switch until maximum fig-
ure appears on the temperature dis-
play.
2. Touch the front windshield switch.
3. Push the “HI” of the air flow control switch to obtain a maximum air flow.
4. Leave the air conditioning on −off button
off. When the front windshield switch is
touched, the air conditioning is set to op-
erate and the OUTSIDE AIR mode is set.
If you touch the front windshield switch
once again while in the FRONT WIND-
SHIELD mode, the mode then returns to
the last mode used.
The indicator will come on in the instru-
ment cluster while the FRONT WIND-
SHIELD mode is on.
CAUTION
Do not use the front windshield
switch during cooled air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
could cause the outer surface of the
windshield to fog up blocking your
vision.

The light sensor is located on the driv-
er ’s side edge of the instrument panel.
If you put anything on this area or
cover the area, the sensor function
may be adversely affected.
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
On cold days, set the fan speed to
high for a minute to help clear the
intake ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
OUTSIDE AIR and the fan speed se-
lector to any setting except “OFF”.
If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior.

operating a garage door or other
device. Make sure people and ob-
jects are out of the way of the ga-
rage door or other device to pre-
vent potential harm or damage.
Do not use this HomeLink\b Univer-
sal Transceiver with any garage
door opener that lacks the safety
stop and reverse feature as re-
quired by federal safety standards.
(This includes any garage door
opener model manufactured before
April 1, 1982.) A garage door open-
er which cannot detect an object
(signaling the door to stop and re-
verse), does not meet current feder-
al safety standards. Using a garage
door opener without these features
increases risk of serious injury or
death.
This device complies with Part 15 of the
FCC Rules and with RSS −210 of the IC
Rules. Operation is subject to the fol-
lowing two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.

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).

REGENERATIVE BRAKE
When the brake is applied, the electric
motor used as a generator converts kinet-
ic energy into electric energy.
The regenerative brake works in the fol-
lowing operations.1. When the accelerator pedal is re- leased, the reduced speed equal to en-
gine braking in a gasoline −fueled ve-
hicle is obtained in accordance with the
running mode position of the shift le-
ver.
2. When the brake pedal is depressed with the shift lever in “D” or “B”, the
regenerative brake works. HYDRAULIC BRAKE
This brake system has 3 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 increase. 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 ACTUATOR
The brake actuator uses brake fluid pres-
surized by the pump to power
−assist the
brakes. If the brake actuator 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 yellow brake system warning light
may stay on for about 60 seconds after
the “IG
−ON” mode is enabled. It is normal
if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red 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.
In the following conditions, you may hear
a motor sound in the engine compartment.
The brake pedal is depressed when the
hybrid system is turned off.
The driver ’s door is opened.
For a few seconds after the hybrid
system is “OFF” and a bout 90 seconds
have passed.
The brake pedal stroke may be short
when you press the “POWER” switch with
the brake pedal depressed.

“ABS” warning light
The light comes on when the “IGON”
mode is enabled. If the antilock brake
system works 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
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 components 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
“IG −ON” mode is enabled, or the
“READY” light 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 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.
Either of the following conditions may
occur, but does not indicate a malfunc-
tion:
The light may stay on for about 60
seconds after the “IG
−ON” mode is en-
abled. It is normal if it turns off after
a whi l e.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if
it turns off after a few seconds. BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment. This does not indicate a
malfunction.
The brake assist system becomes opera-
tive 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).
For an explanation of this system’s warn-
ing light, see “Service reminder indicators
and warning buzzers” on page 117.

215
The electric power steering system, us-
ing an electric motor, assists the turn-
ing of the steering wheel.
In the following cases, you may feel the
steering becomes heavy. However, the
electric power steering system warning
light does not come on. (Because it is
not a malfunction.)
When maneuvering the steering fre-
quently or keeping the steering wheel
turned fully while the vehicle is stopped
or moving very slowlyThe power steering effect will be re-
duced to prevent the system from over-
heating. Avoid turning the steering
wheel, or stop the vehicle. When you
leave the vehicle in the “IG −ON” mode
for a while, the system will become
cool.
NOTICE
If you repeat the operation which will
turn on the overheating prevention
function, the electric power steering
system may be damaged.
When the auxiliary battery is dis-
charged
Check the auxiliary battery’s condition.
If necessary, recharge or replace the
battery. For details, see “Checking aux-
iliary battery condition” on page 300.
When the steering wheel is operated
with the hybrid system not to be turned
on (with the “READY” light off)
The auxiliary battery capacity is de-
creased temporarily. The system re-
turns to normal some time after the
hybrid system is turned on.
If there is a problem somewhere in the
electric power steering system, the warn-
ing light comes on in the multi −information
display. For details, see “Multi −information
display” on page 124.30p003
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

Toyota does not recommend towing a
trailer with your Toyota. It is not de-
signed for trailer towing.Improving fuel economy is easy
−just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See page
291 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Accelerate slowly and smoothly.
Avoid jackrabbit starts.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes power.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on brake ped-
al. This causes premature wear, over-
heating and poor fuel economy.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tunedup and in
top shape . A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance.
Trailer towing How to save fuel and make
your vehicle last longer, too

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
hybrid system” on page 234 and that you
have sufficient fuel. Also check whether
the other keys will start the hybrid
system. If they work, your key may be
broken. Have the key checked at your
Toyota dealer. If none of your keys work,
there may be a malfunction in the hybrid
vehicle immobilizer system. Call your
Toyota dealer. (See “Keys” on page 20.)
If the instrument cluster dims or the
instrument cluster display turns off
with the hybrid system on—1. Check that the auxiliary battery termi- nals are tight and clean.
2. If the auxiliary battery terminals are O.K., the auxiliary battery is dis-
charged. You may try jump starting.
See “(b) Jump starting” for further in-
structions.
NOTICE
Hybrid vehicles cannot be push
started.
If the instrument cluster is shown in
appropriate brightness with the hybrid
system is in the “IGON” mode—
The hybrid vehicle system is suspected to
be faulty. Contact your Toyota dealer. If the auxiliary battery is discharged,
the hybrid system can be started by
jump starting. Depending on the vehicle
condition, the engine may not start.
To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If the auxiliary battery is discharged, you
cannot access to the auxiliary battery in
the luggage compartment because the
back door cannot be opened. Use the ex-
clusive jump starting terminal in the en-
gine compartment. For details, see “JUMP
STARTING PROCEDURE” on page 243.
NOTICE
If the auxiliary battery is discharged
with the transaxle in “P”, your vehicle
cannot be moved unless the front
wheels are raised. This is because the
front wheels are locked by means of
the parking lock mechanism.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent qualified
technician or towing service.
If your vehicle will not start—
