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 5 for details.
Gradual or non −abrupt acceleration and
deceleration will make more effectively
use of the traction motor without hav-
ing to use 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 engine operates
but electricity cannot be generated. The
hybrid battery will be discharged requir-
ing unnecessary engine power to re-
charge.
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 311 in Section 3.
INFORMATION
The engine starts and stops automati-
cally. (It stops during a low load driv-
ing, deceleration or when the vehicle
is stopped.)
As long as the “READY” light remains
on, you can start your vehicle using
the traction motor even with the en-
gine stopped.
The engine may not stop automatical-
ly in the following conditions:
 During engine warmup
 During hybrid battery charging
 During low or high hybrid battery
temperature
Efficient use of your hybrid
vehicle

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.

The engine may not start even with the
“READY” light on.
If there is a problem somewhere in the
hybrid system, the message “CHECK
HYBRID SYSTEM” will appear on the
multi−information display. Have your
vehicle checked by your Toyota dealer as
soon as possible.
If the hybrid system will not start...
In the following cases, the hybrid system
will not start.
If a buzzer sounds from the vehicle,
and the message “KEY IS NOT
DETECTED” appears on the multi −infor-
mation display and the master warning
light comes on when pressing the
“POWER” switch, this indicates that the
key is not in the vehicle.
If the key is placed in the trunk, the
hybrid system cannot be started.
There are instances in which the hybrid
system will not start, even if the key
is in the vehicle (e.g. on the floor, in
the cup holder or glove box).
When the push button start function
does not operate properly, the following
may be causes:
The key battery may be discharged if
the electronic key does not work.
You can start the hybrid system by
touching the Toyota logo side of the
electronic key to the “POWER” switch.
For details, see “Smart key system” on
page 32 in Section 1 −2.
Replace the key battery as soon as
possible. (See “—Replacing battery” on
page 30 in Section 1 −2.)

If the warning light is still lit when the key
is in the vehicle, the key battery is dis-
charged. Check that the indicator light on
the key comes on by pushing the lock
button on the key. When the indicator light
does not come on, change the key battery
so that smart key system works properly.
(B) A warning buzzer sounds once fromthe instrument cluster, accompanied
by three warning sounds from the
vehicle when the driver gets out of
the vehicle and closes the door.
This indicates that the driver is attempting
to leave the vehicle carrying the key with
“POWER” switch turned off although the
transmission selector lever has been set
in the “P” position. The message “KEY IS
NOT DETECTED” will also appear on the
multi −information display and the master
warning light will come on.
Get out of the vehicle only after turning
off the hybrid system by pressing the
“POWER” switch and checking that the
indicator light on the “POWER” switch has
gone off. If the driver returns to the ve-
hicle without carrying the key and begins
driving, a warning buzzer will sound once
more. (C) A warning buzzer sounds from the
vehicle for two seconds after locking
the door with the door handle
switch.
This indicates that the driver is attempting
to lock the doors while carrying the key,
neglecting to follow the instructions for
case (B) above.
Lock the doors only after turning off the
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
turned off. The message “SHIFT TO P
RANGE” will also appear on the multi −in-
formation display.
Get out of the vehicle only after setting
the transmission selector lever in the “P”
position, turning off the hybrid system by
pressing the “POWER” switch and
checking that the indicator light on the
“POWER” switch has gone off.
