(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.

it is no problem to continue driving. How-
ever, if the red warning light comes on,
it indicates a serious problem and you can

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.

The red and yellow warning light may
stay on for about 60 seconds after the
hybrid system is started. It is normal

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.

tem off.
The brake pedal stroke may be short

(j) Engine Oil Replacement ReminderLight (for vehicles sold in the
U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the “IG −ON”
mode is enabled, and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after engine oil replacement, this
light illuminates for about 3 seconds and
then flashes for about 12 seconds when
the hybrid system is in the “IG −ON”
mode. If you continue driving without en-
gine oil replacement, and if the driving
range exceeds 8000 km (5000 miles), the
light will come on after the “IG −ON” mode
is enabled. The light will remain on there-
after. If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace the oil as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Press the “POWER” switch to the “OFF” mode
with the odometer reading
shown. (For details, see “Odometer and
two trip meters” on page 123.)
2. Press the “POWER” switch twice to select the “IG −ON” mode while holding
down the trip meter reset button.
Hold down the button for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
remain flashing. (k) “VSC” Warning Light

If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the “IG −ON” mode is enabled.
