NOTICE
To ensure correct audio system op-
erations:
Be careful not to spill beverages
over the audio system.
 Do not put anything other than a
cassette tape into the cassette tape
slot.
 The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio system which you are listening
to. However, this does not indicate
a malfunction.
RADIO RECEPTION
FM broadcasts have a range of about 40
km or 25 miles. When driving away from
a station, you may have to fine −tune your
radio and turn up the volume as the sta-
tion gets weaker. Because FM uses a
line −of −sight signal, tall buildings or hills
may sometimes block reception. These
are all normal characteristics of FM recep-
tion and do not indicate any problem with
the radio itself. CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)
Use high −quality cassettes:
Low −quality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant auto −reversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.

Clock
28p009c
The digital clock indicates the time.
The key must be in the “ACC” or “ON”
position.
To set the hour: Push the “H” button.
To reset the minutes: Push the “M” button.
If the electrical power source has been
disconnected from the clock, the time dis-
play will automatically be set to 1:00 (one
o’clock).
When the instrument panel lights are
turned on, the brightness of the time indi-
cator will be reduced.
Power outlet
28p010
The power outlet is designed for power
supply for car accessories.
The key must be in the “ACC” or “ON”
position for the power outlet to be used.
NOTICE
To prevent the fuse from being
blown, do not use the electricity
over the total vehicle capacity of
12V/120W.
 To prevent the battery from being
discharged, do not use the power
outlet longer than necessary when
the hybrid system is not operating.
Close the power outlet lid when the
power outlet is not in use. Inserting
a foreign object other than the ap-
propriate plug that fits the outlet,
or allowing any liquid into the out-
let may cause electrical failure or
short circuits.

146
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:
Do not drive over 100 km/h (62 mph).
Avoid full −throttle starts.
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 3.5 −M93
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, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no
cause 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.

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.
Tips for driving in various
conditions

166
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
214 in Section 8 −2 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.
CAUTION
Never turn off the hybrid system to
coast down hills. Your power steering
and brake booster will not function
without the hybrid system running.
Also, the emission control system op-
erates properly only when the hybrid
system is running.
