Clock
28p009d
The digital clock indicates the time.
The hybrid system must be in “ACC” or
“IG−ON”.
To set the hour: Push the “H” button.
To set 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.
When the instrument panel lights are
turned on, the brightness of the time indi-
cator will be reduced. The rear view monitor system assists
the driver by displaying an image of
the view behind the vehicle while back-
ing up. The image is displayed in re-
verse on the screen. This allows the
image to appear in the same manner as
that of the rear view mirror.
To display the rear view image on the
screen, place the selector lever in the
“R” position when the “IGON” mode is
enabled.
If you move the selector lever out of the
“R” position, the screen returns to the
previous screen. Operating another func-
tion of the navigation system will display
another screen.
The rear view monitor system is a supple-
ment device intended to assist back up.
When backing up, be sure to check be-
hind and all around the vehicle visually.
CAUTION
Never depend on the rear view
monitor system entirely when back-
ing up. Always make sure your in-
tended path is clear.
Use caution just as you would when
backing up any vehicle.
Never back up while looking only at
the screen. The image on the
screen is different from actual con-
ditions. Depicted distances between
objects and flat surfaces will differ
from actual distances. If you back
up while looking only at the screen,
you may hit a vehicle, a person or
an object. When backing up, be
sure to check behind and all around
the vehicle visually and with mir-
rors before proceeding.
Do not use the system when the
back door is not completely closed.

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.

28p010a
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.

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 \bC
(14 \bF).)
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 fuel has leaked onto the
ground, the fuel system has been
damaged and 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 red and 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 and yellow brake
system warning light and buzzer. It is nor-
mal 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.
Brake system

328
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
increase.
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 stability
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, the slip indicator in
the instrument cluster flashes and you
will 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
performance.
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). Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti
−lock brake sys-
tem.
When the antilock brake system is ac-
tivated, the following condition may oc-
cur. They do not indicate a malfunction
of the system:
You may hear the anti −lock brake sys-
tem operating and the vibrations of the
vehicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.

330
“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 on), the
anti−lock brake system does not operate,
but the brake system still operates con-
ventionally.
If any 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 function and brake as-
sist function will fail but also the ve-
hicle will become extremely unstable
during braking.
Any of the following conditions may oc-
cur, 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 125.

331
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.
