(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 warning light turning on briefly dur-
ing 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.

In the following case, drive directly to
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 warning light. 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 p edal 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 turned off.
The brake pedal stroke may be short
when you turn the key to the “START”
position with the brake pedal de-
pressed.
(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 “ON”,
the reminder light flashes and 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
stops after about 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON”,
the reminder light flashes if a passenger
sits in the front passenger seat and does
not fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash. (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) Traction Battery Warning Light
This light comes on in the following
cases:
a. The traction battery voltage drops be- cause the transmission is left in the
“N” position.
If you put the transmission in the “P”
position and the light goes off, the system
is working properly. b. The traction battery is discharged.
If the traction battery is discharged and
the warning light comes on along with the
“READY” light, stop your vehicle in a safe
place and contact your Toyota dealer.

tem is operating properly.

ately.

(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.

ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual. (h) “ABS” Warning Light
This light comes on when the ignition key
is turned to the “ON” position. If the anti
−
lock brake system function of the VDIM
(vehicle dynamics integrated management)
is working properly, the light goes off
when the “READY” light comes on. There-
after, if the function malfunctions, the light
comes on again.
When the “ABS” warning light is on and
the yellow brake system warning light is
on, the anti −lock brake system function
and the brake assist function of the VDIM
may not operate so that the wheel could
lock up during a sudden braking or brak-
ing on slippery road surfaces However,
the brake system still operates conven-
tionally.
When the “ABS” warning light is on and
the yellow brake system warning light is
off, the anti −lock brake system function of
the VDIM does not operate so that the
wheels could lock up during a sudden
braking or braking on slippery road surfa-
ces. However, the brake system still oper-
ates conventionally.
