(a) Brake System Warning Lights
These lights come on in the following
cases when the ignition key is in the “ON”
position.
RED WARNING LIGHT
When the parking brake is applied...
This light comes on when the ignition is
turned on, even after the parking brake is
released. When the vehicle speed exceeds
5 km/h (3 mph), a message “PARK
BRAKE” appears on the multi −information
display, the master warning light flashes
and a warning tone 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
or electronically controlled brake
system fails...
When the yellow warning light comes on,
the regenerative brake system and/or elec-
tronically controlled brake system is mal-
functioning. Take your vehicle to your
Toyota dealer.
RED AND YELLOW WARNING LIGHT
When the hydraulic brake system
fails...
If the red and yellow warning lights come
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 hy-
brid system is on.
The lights do not come on when the
ignition is turned on 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 with the hybrid system
turned on.
The red warning light stays on.
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 red brake system warning light
remains on together with the “ABS”
warning light and “CHECK VSC
SYSTEM” warning message.
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.

the nearest Toyota dealer.
The yellow warning light comes on
while driving.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The red and yellow warning lights 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 lights. It is normal if the light turns
off 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.

engine compartment when the brake
pedal is depressed with the hybrid sys-
tem turned off.
The brake pedal stroke may be short
when you turn the ignition key to the
“START” position with the brake pedal
depressed.
(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 ignition key is turned to the
“ON” position, the buzzer sounds for about
6 seconds and the reminder light flashes
if the driver ’s seat belt is not fastened.
Unless the driver fastens the belt, the
light continues flashing.
If the vehicle speed rises above 15 km/h
(9 mph) with the seat belt unfastened, the
buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 20 more seconds. Even if the vehicle
speed drops below 15 km/h (9 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. (c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the ignition key is turned to the
“ON” position, 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 continues flashing.
If the vehicle speed rises above 15 km/h
(9 mph) with the seat belt unfastened, the
buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 20 more seconds. Even if the vehicle
speed drops below 15 km/h (9 mph), the
buzzer will continue to sound. To stop
the buzzer, fasten the seat belt.
If luggage or other 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 flash and buzzer to sound.
