Drive your vehicle with smooth accel-
eration and deceleration.
While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for effi-
cient use, do not accelerate or deceler-
ate your vehicle more than necessary.
Avoid abrupt acceleration and decelera-
tion.
The power of the traction battery can
be checked on the multi−information
display or the navigation system screen
(with navigation system). See “—Trac-
tion battery status” on page 4 for de-
tails. Gradual or non −abrupt accelera-
tion and deceleration will make more
effectively use of the traction motor
without having to use gasoline engine
power. When parking, be sure to put the trans-
mission into the “P” position. While
driving, put the transmission into the
“D” position.
In the “N” position, the gasoline engine
operates but electricity cannot be gen-
erated. The traction battery will be dis-
charged requiring unnecessary engine
power to recharge.
The hybrid system automatically re-
charges the traction battery when the
remaining battery power is reduced.
However, the traction battery cannot be
recharged if the transmission is in the
“N” position.
For detailed information, see “How to save
fuel and make your vehicle last longer” on
page 337 in Section 3.
INFORMATION
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle is stopped.)
As long as the “READY” light remains
on, you can start your vehicle using
the electric motor even with the gaso-
line engine stopped.
The gasoline engine may not stop au-
tomatically in the following condi-
tions:
 During gasoline engine warmup
 During traction battery charging
 During low or high traction battery
temperature
Efficient use of your hybrid
vehicle

3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clip—this prevents rattles. Then lower the
hood and make sure it locks into place.
If necessary, press down gently on the
front edge to lock it.
CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
To deter vehicle theft, the system is
designed to sound an alarm if any of
the side doors, back door or hood is
forcibly unlocked or the battery termi-
nal is disconnected and then recon-
nected when the system is set.
The alarm blows the horn intermittently
and flashes the headlights, tail lights and
turn signal lights, and turns on the interior
light.SETTING THE SYSTEM 1. Turn the ignition key to the “LOCK” position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See “Engine immobilizer system”
on page 25 in this Section for details.)
2. Have all passengers get out of the vehicle.
3. Close and lock all the side doors, back door and hood.
The indicator light will remain on when all
the side doors, back door and hood are
closed and locked.

the cooling system as this may
cause the hybrid system to over-
heat. The thermostat is designed to
control the flow of coolant to keep
the temperature of the engine with-
in the specified operating range.
 Continued driving with the message
displayed could result in the over-
heating of the hybrid system.

“ABS” warning light
When the ignition is turned on, the
“ABS” warning light comes on. It will
go off when the “READY” light comes
on. If the “ABS” warning light does not
come on when the ignition is turned
on, contact your Toyota dealer.
If the “ABS” warning light remains on
after the ignition is turned on or if it
comes on while driving, the antilock
brake system function may not operate
properly. Although the brake system op-
erates without the function, drive care-
fully and have your vehicle checked by
a Toyota dealer as soon as possible.
For details, see “Service reminder indi-
cators and warning buzzers” on page
144 in Section 16.
Warning message “CHECK VSC SYSTEM”
If “CHECK VSC SYSTEM” appears on
the multiinformation display, the trac-
tion control and vehicle stability control
functions may not operate properly. Al-
though the brake system operates nor-
mally without these functions, drive
carefully and have your vehicle checked
by a Toyota dealer as soon as possible.
For details, see “—Warning messages”
on page 155 in Section 16. BRAKE ASSIST FUNCTION
The brake assist function is designed to
assist with emergency braking. When the
driver suddenly depresses the brake ped-
al, the device treats it as emergency brak-
ing and adds braking force.
If you slam the brakes on or apply the
brakes more firmly, more powerful braking
will be applied. At this time, you may hear
a sound in the engine compartment and
feel the vibrations of the brake pedal. This
does not indicate a malfunction.
CAUTION
The brake assist function is not de-
signed to shorten braking distance.
Always drive at a moderate speed and
maintain a safe distance from the ve-
hicle in front of you. Depending on
road conditions, braking distance may
be longer than that of a vehicle with-
out the brake assist device. If tire
chains are used, braking distance
may become longer.

ANTILOCK BRAKE SYSTEM FUNCTION
The anti −lock brake system function is de-
signed to help prevent lock −up of the
wheels during sudden braking or when
braking on slippery road conditions. This
assists in providing directional stability
and steering performance of the vehicle
under these circumstances.
Effective way to press the ABS brake
pedal: When the anti −lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti −lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking perfor-
mance.
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti −lock brake sys-
tem function. You may hear a click or motor sound in
the engine compartment for a few seconds
just after the vehicle begins to move. This
means that the anti
−lock brake system
function is in the self −check mode, and
does not indicate a malfunction.
When the antilock brake system func-
tion is activated, the following condi-
tions may occur. They do not indicate
a malfunction of the function:
You may hear the anti −lock brake sys-
tem function operating and feel the
brake pedal pulsating and the vibra-
tions of the vehicle body and steering
wheel. You may also hear the motor
sound in the engine compartment even
after the vehicle is stopped.
At the end of the activation, the brake
pedal may move a little forward.
CAUTION
The antilock brake system function
is not designed to shorten braking
distance. Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you. De-
pending on road conditions, braking
distance may be longer than that of
a vehicle without the antilock brake
device. If tire chains are used, brak-
ing distance may become longer.
