is fails...
RED OR YELLOW WARNING LIGHT

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 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 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.

system.
The light will come on when the “IG−ON”
mode is enabled and will go off after the

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.

dealer:

after the “IG −ON” mode is enabled.
The warning light remains on after the
“READY” light comes on.

bility control system will fail but also
the vehicle will become extremely un-
stable during braking.
