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 the “POWER” switch
off 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 system 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 enclosed area except for
the time needed to drive the vehicle
in or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the hybrid sys-
tem operating. If it is unavoidable,
however, do so only in an uncon-
fined area and adjust the heating or
cooling system to force outside air
into the vehicle.

Keep the trunk lid closed while
driving. An open or unsealed trunk
lid 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 trunk lid to ensure plenty
of fresh air enters the vehicle. 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 inhalation of ex-
haust 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.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high −speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 lmp. qt./600
miles)
Facts about engine oil
consumption

When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an express way, making it
appear that oil is excessively consumed
after driving at high speeds.IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” on
page 355 in Section 7
−2.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs.
Do not adjust gaps for engine perfor-
mance or smooth driveability.

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.

hybrid system by pressing the “POWER”
switch and checking that the indicator light
on the “POWER” switch has gone off.
A warning buzzer that sounds even though
the engine has been turned off indicates
that driver is attempting to lock the ve-
hicle with the keys still in the vehicle.
Leave the vehicle only after making sure
that you are carrying the key. (D) A warning buzzer sounds continu-
ously from the instrument cluster
when opening the driver ’s door.
This indicates that the transmission selec-
tor lever is in a position other than “P”
and that the “POWER” switch is not
