The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly full–Indicator at “F”
Nearly empty–Indicator at “E”
It is a good idea to keep the tank over
1/4 full.
When you refuel on the slope, the indica-
tor may not show the correct level.
When you refuel less than about 11.4 L
(3.0 gal., 2.5 lmp. gal.), the fuel indicator
may not change.
After the auxiliary battery is reconnected,
one segment will flash for a while.Depending on the ambient temperature,
the fuel quantity is less than 45 L (11.9
gal., 9.9 lmp. gal.) even at “F”. However,
this does not affect the fuel consumption
and the remaining fuel ratio indicated on
the gauge. (For details, see “Fuel” on
page 146 in Section 3.)

The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
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 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 p edal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction. (b) Driver’s Seat Belt Reminder Light
and Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to ”ON” or
”START”, the reminder light flashes and
the buzzer sounds if the driver ’s seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps on flashing and
the buzzer sounds 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Unless
the front passenger fastens the belt, the
light stays flashing.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, built −in
sensors in the seat cushion may detect
the pressure, causing the reminder light to
come on. (d) 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.

(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following:
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
This case is a temporary malfunction. The
malfunction indicator lamp will go off after
taking several driving trips.
If the lamp will not go off even after
several trips, contact your Toyota deal-
er as soon as possible.
There is a problem somewhere in the
hybrid system or warning light system
itself.
Contact your Toyota dealer as soon as
possible to service the vehicle. Emissions inspection and maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (On
−Board Diag-
nostics) system before taking your vehicle
for the inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 198
in Section 7.
(f) Master Warning Light
()
If the master warning light comes on, the
warning light for the faulty system is high-
lighted or the message such as “When
you park your car, make sure you shift to
Park P.” and “The batteries will not charge
if the shifter is in N” appears on the mul-
ti −information display. (See “Service re-
minder indicators and warning buzzers—
—Multi −information display” on page 97
in this section or “Precautions for use” on
page 12 in Section 1 −2 or “Fuel gauge”
on page 88 in Section 2− 4 for instruc-
tions.) (g) Output Control Warning Light
()
This light comes on when the ignition
switch is on. It goes off when the electric
motor is ready to run.
The warning light comes on when the hy-
brid vehicle battery temperature is low or
high, or the hybrid vehicle battery capacity
is decreased with the selector lever at “R”
during driving. If the light comes on, the
power will be limited. Drive your vehicle
without hard acceleration.
(h) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or 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 occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
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.

(a) Power Steering System Warning
Light
This light comes on when the power
steering control system fails.
If the vehicle starts moving on the decline
before the ignition is turned on, turning
the ignition switch to “ON” will light up
this light. At this time, you may feel the
steering wheel heavy.
If this occurs, stop your vehicle complete-
ly, turn the ignition switch to “ACC” or
“LOCK” and start the hybrid system again.
CAUTION
If this light comes on, take your ve-
hicle to the Toyota dealer as soon as
possible. In this case, you may feel
the heavy steering wheel maneuver-
ing. Drive your vehicle while gripping
the steering wheel firmly.
(b) Hybrid Vehicle Battery Warning Light
This light comes on in the following
cases.
a. The hybrid vehicle battery voltage
drops with the running mode selector lever
left in “N” position.
The system works properly if you put the
running mode selector lever to “P” position
and the light goes off.
b. The fuel tank is completely empty. (See
“Fuel gauge” in this section for instruc-
tions.)
c. The hybrid vehicle battery is dis-
charged.
If this light comes on with the “READY”
light on in case of c., stop your vehicle
in a safe place and contact your Toyota
dealer.

“START”—The hybrid system is ready
to operate.
Turn the key to the “START” position and
hold the ignition switch at this position for
about a few seconds until the “READY”
light comes on and a beep sounds. (If the
ambient temperature is low such as during
winter conditions, it may take time until
the “READY” light is on.” The key will
return to the “ON” position when released.
Being different from ordinary vehicles, you
cannot start your vehicle with the running
mode selector lever in “N” position.
“ON”—The hybrid system starts to run
when the accelerator pedal is depressed
with the “READY” light and all accesso-
ries on.This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the hybrid system is off.
If you leave your key in the “ACC” posi-
tion for a while, put the running mode
selector lever in “P” position.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.
“LOCK”—The hybrid system is off and
the steering wheel is locked. The key
can be removed only at this position.
You must push in the key to turn it from
“ACC” to the “LOCK” position. The selec-
tor lever must be put in the “P” position
before pushing the key.
Vehicles with hybrid vehicle immobiliser
system–Once you remove the key, the hy-
brid vehicle immobiliser system is auto-
matically set. (See “Hybrid vehicle immobi-
liser system” on page 20 in Section 2
−1.)
When starting the hybrid system, the key
may seem stuck at the “LOCK” position.
To free it, first be sure the key is pushed
all the way in, and then rock the steering
wheel slightly while turning the key gently.
NOTICE
Do not leave the key in the “ACC” or
“ON” position for a long time when
the hybrid system is off. The auxiliary
battery will discharge.

105
If the driver ’s door is opened when the
the “READY” light is on and the the selec-
tor lever is at a position other than “P”
with the parking brake applied, you will
hear beeps to warn you to shift the selec-
tor lever to the “P” position.
CAUTION
While the vehicle is moving, never
attempt to move the running mode
selector lever into “P” position under
any circumstances. Serious mechani-
cal damage and loss of vehicle con-
trol may result.
NOTICE
Be sure to put the selector lever in
“P” position when parking. With the
selector lever in “N” position, the hy-
brid vehicle battery will not be
charged even the gasoline engine op-
erates. You cannot start your vehicle
if the selector lever is left in “N”
position for a long time because the
hybrid vehicle battery will discharge.
(f) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, vehicle is designed
like an ordinary automatic transmission
vehicle which tends to move without de-
pressing the accelerator pedal with the
selector lever in a position other than “P”
or “N”.
With the selector lever in a position other
than “P” or “N”, depress the brake pedal
firmly even when stopped and apply the
parking brake as required.
When moving in a restricted area or dur-
ing traffic jam, it is an effective way to
control the speed using only the brake
pedal operation without depressing the ac-
celerator pedal.
Regenerative brake
When the accelerator pedal is released or
the brake pedal is depressed, the electric
motor acts as a generator and converts
kinetic energy to electric energy to provide
deceleration and recover the electric ener-
gy to charge the hybrid vehicle battery.
At this time, the electric motor running
noise becomes larger.The operation is the same as an ordinary
gasoline powered vehicle.
You may experience the following condi-
tions while braking. As they do not indi-
cate the malfunction, perform braking as
usual:
When you turn the ignition switch to
“ON” with the brake pedal depressed,
you may feel a little push from the
brake pedal.
When you turn the ignition switch to
“ACC” or “LOCK” from “ON”, the brake
pedal may move a little.

106
Hybrid driving
This vehicle runs in combination with the
gasoline engine and electric motor.
If the “READY” light is on, you can start
your vehicle even with the gasoline engine
stopped.
When the hybrid vehicle battery tempera-
ture is low or high, or the hybrid vehicle
battery capacity is decreased with the run-
ning mode selector lever at “R” during
driving, the output control warning light is
on and the output power may be limited.
If the output control warning light is on,
drive your vehicle without hard accelera-
tion. The output power will be limited par-
ticularly when backing up.
(g) If you cannot shift lever out of “P”position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift running mode selector
lever” on page 182 in Section 5.

pedal while depressing the brake pedal.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Driving with the parking brake en-
gaged can reduce braking power.
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
