INFORMATION:
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle is stopped.)
If the “READY” light remains on, you
can start your vehicle using the electric
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions:
During gasoline engine warmup
 During hybrid vehicle battery charg-
ing
 During low or high hybrid vehicle
battery temperature The vehicle runs in combination with
the gasoline and electric power. Pay
special attention to the following items.
Be careful of high voltage and high
temperature.
Your vehicle is equipped with the orange
colored cables connected to the hybrid
vehicle battery (about 200 V) and to other
components that are all high voltage.
CAUTION
Do not touch or come in contact with
orange cables or battery terminals.
Electric shock may cause serious in-
jury or death. Read all caution labels.
An electric motor, coolant radiator and
some other parts reach high temperature
while driving. Caution labels are applied to
these parts. Carefully observe the instruc-
tions on these caution labels.
CAUTION

Precautions for use

126
(a) Discharge Warning Light
This light warns that the auxiliary battery
is being discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The hybrid system will continue to oper-
ate, however, until the auxiliary battery is
discharged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.(b) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it stays on while you are driving, pull
off the road to a safe place and stop the
engine immediately. Call a Toyota dealer
or qualified repair shop for assistance.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(c) High Coolant Temperature Warning Light
The light operates to warn that the hybrid
system is almost over heating.
If it comes on while you are driving, stop
the vehicle and check your hybrid system.
For detailed instructions, see “If your ve-
hicle overheats” on page 246.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
NOTICE
 Do not remove the thermostat in
the cooling system as this may
cause the hybrid system to over-
heat. The thermostat is designed to
control the flow of coolant to keep
the temperature of the hybrid sys-
tem within the specified operating
range.
 Continued driving with the light on
could result in the overheating of
hybrid system.

Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations—Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multi−path—FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.
Static and fluttering—These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping—If the FM signal you
are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the origi-
nal signal can be picked up again. AM
Fading—AM broadcasts are reflected by
the upper atmosphere—especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound
alternately strong and weak.
Station interference—When a reflected sig-
nal and a signal received directly from a
radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static—AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
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.
CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS
The player is intended for use with
12cm (4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning
to cool the vehicle interior before you
listen to a disc.

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.
27p116a
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.
(b) Windshield defogging and
defrosting

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.
