about 6 seconds. This means the SRS
side airbags and curtain shield airbags
are operating properly. The warning light system monitors the air-
bag sensor assembly, front airbag sen-

The “AIRBAG ON” and “AIRBAG OFF”
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger ’s seat belt pretensioner.
The “AIRBAG OFF” indicator light will be
illuminated when the “IG−ON” mode is en-
abled with the condition 2 in the table
shown below.
If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the rear seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “AIRBAG ON” indicator
light is illuminated when an adult is
seated in the front passenger seat. If the
“AIRBAG OFF” indicator light is illumina-
ted, ask the passenger to sit up straight,
well back in the seat, and with the seat
belt worn correctly. If the “AIRBAG OFF”
indicator light still remains illuminated, ei-
ther ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward. The “AIRBAG ON” and “AIRBAG OFF”
indicator lights will be illuminated ini-
tially when the “IGON” mode is en-
abled. After about 4 seconds, they will
go off. After that, the front passenger
occupant classification system operates
and judges which indicator light be illu-
minated.

The gauge indicates the approximate
quantity of fuel remaining in the tank
when the “IGON” mode is enabled.
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 a slope, the indicator
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 12 volt 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 320.)
If the fuel gauge display flashes, there
may be a problem in the system. In this
case, contact your Toyota dealer as soon
as possible.

(a) Brake System Warning Lights andBuzzer
These lights come on in the following
cases when the “IG −ON” mode is enabled.
RED WARNING LIGHT
When the parking brake is applied...
This light comes on when the “IG −ON”
mode is enabled, even after the parking
brake is released.
If the vehicle speed rises above 5 km/h
(3 mph) while the parking brake is ap-
plied, a buzzer sounds.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
YELLOW WARNING LIGHT
When the regenerative brake system
is fails...
RED OR YELLOW WARNING LIGHT
When the hydraulic brake system
fails... When the yellow warning light comes on,
it is no problem to continue driving. How-
ever, if the red warning light comes on,
it indicates a serious problem and you can
continue driving no longer.
Have your vehicle checked at your
Toyota dealer in the following cases:
The lights do not come on even if the
parking brake is applied when the
“READY” light is on.
The lights do not come on even if the
“POWER” switch is pressed with the
parking brake released.
A red or yellow warning light turning on
briefly during operation does not indicate
a problem.
CAUTION
If any of the following conditions oc-
curs, immediately stop your vehicle at
a safe place and contact your Toyota
dealer.
The red warning light does not turn
off even after the parking brake is
released while the hybrid system is
running.
The red warning light comes on or
buzzer sounds continuously.
In either case, this can indicate that
the brakes may not work properly and
your stopping distance will become
longer. Depress the brake pedal firmly
and bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
and “VSC” warning light.
In this case, not only the antilock
brake system and vehicle stability
control system will fail but also the
vehicle will become extremely unsta-
ble during braking.
In the following case, drive directly to
the nearest Toyota dealer.
The yellow warning light comes on
while driving.

128
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The red and yellow warning light may
stay on for about 60 seconds after the
hybrid system is started. It is normal
if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red and yellow warn-
ing light. 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.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem off.
The brake pedal stroke may be short
when you press the “POWER” switch
with the brake pedal depressed.
You may hear a sound in the engine
compartment when the driver ’s door is
opened or the brake pedal is de-
pressed with the hybrid system turned
off. However, this does not indicate any
trouble.
You may hear a sound in the engine
compartment after the hybrid system is
turned on or off. However, this does
not indicate any trouble.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes and the buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
sounds 4 to 8 seconds.
If the vehicle speed rises above 20 km/h
(12 mph) without the belt fastened, a
buzzer sounds. (c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
This light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes if a passenger sits
in the front passenger seat and does not
fasten the seat belt. Unless the front pas-
senger fastens the belt, the light continues
flashing.
If the vehicle speed rises above 20 km/h
(12 mph) without the belt fastened, a
buzzer sounds.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, causing the reminder light to flash
and buzzer to sound.
