Brake system

REGENERATIVE BRAKE
When the brake is applied, the motor gen-
erator converts kinetic energy into electric
energy.
The regenerative brake works in the fol-
lowing operations.
1. When the accelerator pedal is released,
the reduced speed equal to engine
braking in a gasoline−fueled vehicle is
obtained in accordance with the running
mode position of the selector lever.
2. When the brake pedal is depressed
with the selector lever in "D" or "B",
the regenerative brake works.
HYDRAULIC BRAKE
This brake system has 3 independent hy-
draulic circuits. If any circuit should fail,
the other will still work. However, the ped-
al will be harder to press, and your stop-
ping distance will increase. Also,
brake system warning light may come on.
CAUTION
Do not drive your vehicle if any hy-
draulic circuit has failed. Have your
brakes fixed immediately.

BRAKE ACTUATOR
The brake actuator uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake actuator fails during
driving, the brake system warning light
comes on and the buzzer sounds continu-
ously. In this case, the brakes may not
work properly. If they do not work well,
depress the brake pedal firmly. If the
brake system warning light comes on, im-
mediately stop your vehicle and contact
your Toyota dealer.
The red and yellow brake system warning
lights may stay on for about 60 seconds
after the ignition is turned on. It is normal
if the light 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.
the
You may hear a sound in the engine
compartment after the hybrid system is
started or the brake pedal is depressed
repeatedly. This is a pump
sound of the brake system, and it is not
a malfunction.
In the following conditions, you may hear
a motor sound in the engine compartment.
The brake pedal is depressed when the
D
hybrid system is turned off.
The driver's door is opened.
D
For a few seconds after the hybrid sys-
D
tem is off and about 90 seconds have
passed.
The brake pedal stroke may be short
when you turn the ignition on with the
brake pedal depressed.
CAUTION
Do not pump the brake pedal if the
D
hybrid system
Each push on the pedal uses up
your reserved brake fluid pressure.
Even if the power assist is com-
D
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
pulsating
increase.
