REGENERATIVE BRAKE
When the brake is applied, the motor gen-
erator converts kinetic energy into electric
energy.
When applying brakes, you may hear a
sound coming from the motor generator.
However, this does not indicate any
trouble.
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, the
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 hybrid system 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 and
buzzer. It is normal if the light turns off
after a few seconds. In the following conditions, you may hear
a sound in the engine compartment. This
is not a malfunction.
The driver ’s door is opened with the
hybrid system turned off.
The brake pedal is depressed with the
hybrid system turned off.
After the hybrid system is turned on.
The brake pedal is depressed repeated-
ly with the hybrid system turned on.
After the hybrid system is turned off.
The brake pedal may be hard to depress
or the brake pedal stroke may be short
before turning the hybrid system on. This
is not a malfunction.

CAUTION
Do not pump the brake pedal if the
hybrid system is not operating.
Each push on the pedal uses up
your reserved brake fluid pressure.
Even if the power assist is com-
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
increase.
DRUMINDISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum−in −disc type
parking brake system. This type of brake
system n eeds bedding −down of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.
Have your Toyota dealer perform the bed-
ding− down. Driving conditions where the steering
wheel must be turned frequently may
cause an overload to the electric power
steering system. The system will reduce
assistance for sometime to prevent the
power steering from overheating. In this
case, you may feel some resistance when
turning the steering wheel though it is not
a malfunction.
CAUTION
If the “P/S” warning light comes on,
take your vehicle to the Toyota dealer
as soon as possible. In this case, you
may feel the heavy steering wheel
maneuvering. Drive your vehicle while
gripping the steering wheel firmly.
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

NOTICE
If any message appears on the mul-
tiinformation display or service re-
minder indicator light comes on
(see page 140 and page 150 in Sec-
tion 16 for details) or the 12 volt
battery is disconnected, the hybrid
system may not be started. In that
case, push the “POWER” switch
again. If the “READY” light does
not come on, contact your Toyota
dealer.
 When you start the hybrid system
at a lower outside temperature, it
may take longer before the blinking
“READY” light changes to constant
on.
TIPS FOR USING SMART KEY SYSTEM
When using the smart key system, it is
possible to start or stop the hybrid system
as long as the key is on your person.
For this reason, it is possible that a pas-
senger may remove the key from the ve-
hicle without the driver being aware of the
fact. In such a case, it is not possible to
restart the hybrid system after having
turned it off. In addition, it is possible that
one may get out of the vehicle without
being aware that the “POWER” switch has
not been turned off completely.
When driving or getting in or out of the
vehicle, drivers should make sure that
they are carrying the key.
CAUTION
Do not touch the “POWER” switch
while driving.
If you have to make an emergency stop,
press and hold the “POWER” switch for
more than 3 seconds.
