features of the Toyota audio system.
Some information may not pertain to your
system.
Your audio system works when the hybrid
system is in “ACC” or “IG−ON”.
NOTICE
To prevent the battery from being
discharged, do not leave the audio on
longer than necessary when the
hybrid system is not running.

The automatic air conditioning automat-
ically maintains the set temperature.
This air conditioning features automatic
fan speed and air flow control which auto-
matically selects the most suitable fan
speed and air flow to control the tempera-
ture. The hybrid system must be in the
“IG−ON” mode.
CLIMATE: Push this button to display
switches for automatic air conditioning
controls.
NOTICE
To prevent the battery from being dis-
charged, do not leave the air condi-
tioning on longer than necessary
when the hybrid system is not operat-
ing.

Check surroundings for safety.
If a bright light (for example, sunlight re-
flected off the vehicle body) is picked up
by the camera, the smear effect* peculiar
to the camera may occur.
*: Smear effect—A phenomenon that oc-
curs when a bright light (for example, sun-
light reflected off the vehicle body) is
picked up by the camera; when trans-
mitted by the camera, the light source
appears to have a vertical streak above
and below it.
Power outlets

Instrument panel
28p107
Rear console box
The power outlets are designed for
power supply for car accessories.
The hybrid system must be in “ACC” or
“IG−ON” for the power outlets 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
anything other than an appropriate
plug that fits the outlet, or allowing
any liquid to get into the outlet
may cause electrical failure or short
circuits.

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 12 volt battery is discharged
Check the 12 volt battery’s condition.
If necessary, recharge or replace the
battery. For details, see “Checking 12
volt battery condition” on page 418.
When the steering wheel is operated
with the hybrid system not to be turned
on (with the “READY” light off)
The 12 volt 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 133.
When you move the steering wheel, an
electrical motor noise may be heard. This
is power steering motor noise, and is not
a malfunction.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.

You may hear a motor sound in the en-
gine compartment when the brake pedal is
depressed with the hybrid system off.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery in the luggage
compartment. However, this does not indi-
cate any trouble.
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
your Toyota dealer.
CAUTION
Never start the hybrid system from
outside the vehicle, or an accident
may occur. Be sure to sit on the driv-
er seat, then start the system when
driving.
NOTICE
The hybrid system cannot be
started when the shift position is
“N”. Be sure to put it in “P” and
then start the system.
 If any warning light comes on (See
page 125 for details.) or the 12 volt
battery is disconnected, the hybrid
system may not start by pushing
the “POWER” switch. In that case,
push it once again. If the “READY”
light does not come on, contact
your Toyota dealer.
 When you start the hybrid system
at a lowered outside temperature, it
may take longer before the blinking
“READY” light changes to stay on.
40p002d
Before starting the hybrid system, be sure
to follow the instructions in “(a) Before
starting the hybrid system”.
Normal starting procedure
Insert the key and press the “POWER”
switch briefly and firmly with the brake
pedal depressed. The “READY” light starts
blinking. After a few seconds, the blinking
“READY” light remains on and two beeps
sound. (If the ambient temperature is low,
such as during winter driving conditions,
it may take time until the “READY” light
is on.)
The engine may not start even with the
“READY” light on.

You may hear a motor sound in the en-
gine compartment when the brake pedal is
depressed with the hybrid system off.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery in the luggage
compartment. However, this does not indi-
cate any trouble.
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
your Toyota dealer.
CAUTION
Never start the hybrid system from
outside the vehicle, or an accident
may occur. Be sure to sit on the driv-
er seat, then start the system when
driving.
NOTICE
The hybrid system cannot be
started when the shift position is
“N”. Be sure to put it in “P” and
then start the system.
 If any warning light comes on (See
page 125 for details.) or the 12 volt
battery is disconnected, the hybrid
system may not start by pushing
the “POWER” switch. In that case,
push it once again. If the “READY”
light does not come on, contact
your Toyota dealer.
 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 such
as a tire burst.
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 hybrid
transaxle “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 applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Tips for driving in various
conditions

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
hybrid system” on page 350 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 12 volt battery terminals are tight and clean.
2. If the 12 volt battery terminals are O.K., the 12 volt battery is discharged.
You may try jump starting. See “(b)
Jump starting” for further instructions.
NOTICE
Hybrid vehicles cannot be push
started.
If the instrument cluster is shown in
appropriate brightness when the hybrid
system is in the “IGON” mode—
The hybrid vehicle system is suspected to
be faulty. Contact your Toyota dealer. If the 12 volt battery is discharged, the
hybrid system can be started by jump
starting. Depending on the vehicle con-
dition, 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 12 volt battery is discharged, you
cannot access to the 12 volt battery in the
luggage compartment because the back
door cannot be opened. Use the exclusive
jump starting terminal in the engine
compartment. For details, see “JUMP
STARTING PROCEDURE” on page 361.
NOTICE
If the 12 volt 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—
(a) Simple checks
(b) Jump starting
