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 hybrid battery can be
checked on the multi−information dis-
play or the navigation system screen
(with navigation system). See “—Hybrid
battery status” on page 4 for details.
Gradual or non −abrupt acceleration and
deceleration will make more effectively
use of the traction motor without hav-
ing 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 hybrid battery will be dis-
charged requiring unnecessary engine
power to recharge.
The hybrid system automatically re-
charges the hybrid battery when the
remaining battery power is reduced.
However, the hybrid 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 335 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 hybrid battery charging
 During low or high hybrid battery
temperature
Efficient use of your hybrid
vehicle

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.)

“ABS” warning light
When the ignition key is turned to the
“ON” position, 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 conditions such as on a manhole
cover, 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-
tion may occur. This does not indicate
a malfunction of the function:
You may hear the anti −lock brake system
function operating and feel the brake ped-
al pulsating and the vibrations of the ve-
hicle body and steering wheel. You may
also hear the motor sound in the engine
compartment even after the vehicle is
stopped.
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
system. If tire chains are used, brak-
ing distance may become longer.

The threeway catalytic converters are
emission control devices installed in
the exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not idle or park your vehicle
over anything that might burn easi-
ly such as grass, leaves, paper or
rags.
NOTICE
A large amount of unburned gases
flowing into the threeway catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
 Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three
way catalytic converter.
 Do not turn off the ignition while
the vehicle is moving.
 Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel systems could cause an ex-
tremely high threeway catalytic
converter temperature.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a checkup as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
threeway catalytic converter sys-
tem best.
 To ensure that the threeway cata-
lytic converter and the entire emis-
sion control system operate proper-
ly, your vehicle must receive the
periodic inspections required by the
Toyota Maintenance Schedule. For
scheduled maintenance information,
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.
 Do not apply a coating agent such
as an antirust undercoating to the
exhaust pipe.

CAUTION
Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the hybrid system in a
garage or other enclosed areas ex-
cept to drive the vehicle in or out.
In enclosed areas, exhaust gases
cannot escape, making this a partic-
ularly dangerous situation.
Do not remain for a long time in a
parked vehicle with the hybrid sys-
tem on. If it is unavoidable, howev-
er, make sure to park the vehicle in
an unclosed area and adjust the
heating or cooling system to force
outside air into the vehicle.
Keep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle.
To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, open the windows and
close the back door to ensure
plenty of fresh air enters the ve-
hicle. If you can smell exhaust
fumes even though there are no
other vehicles in the surrounding
area, have your vehicle checked by
your Toyota dealer. Continued in-
halation of exhaust fumes can lead
to death by gas poisoning.
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
