(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following:
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
This case is a temporary malfunction. The
malfunction indicator lamp will go off after
taking several driving trips.
If the lamp will not go off even after
several trips, contact your Toyota deal-
er as soon as possible.
There is a problem somewhere in the
hybrid system or warning light system
itself.
Contact your Toyota dealer as soon as
possible to service the vehicle. Emissions inspection and maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (On
−Board Diag-
nostics) system before taking your vehicle
for the inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 198
in Section 7.
(f) Master Warning Light
()
If the master warning light comes on, the
warning light for the faulty system is high-
lighted or the message such as “When
you park your car, make sure you shift to
Park P.” and “The batteries will not charge
if the shifter is in N” appears on the mul-
ti −information display. (See “Service re-
minder indicators and warning buzzers—
—Multi −information display” on page 97
in this section or “Precautions for use” on
page 12 in Section 1 −2 or “Fuel gauge”
on page 88 in Section 2− 4 for instruc-
tions.) (g) Output Control Warning Light
()
This light comes on when the ignition
switch is on. It goes off when the electric
motor is ready to run.
The warning light comes on when the hy-
brid vehicle battery temperature is low or
high, or the hybrid vehicle battery capacity
is decreased with the selector lever at “R”
during driving. If the light comes on, the
power will be limited. Drive your vehicle
without hard acceleration.
(h) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.

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
piston moves downwards in the cylin-
der. 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 com-
bustion 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.
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 expressway, 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.

consumption

For detailed information on oil level check,
see “Checking the engine oil level” on
page 208 in Section 8−2.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drivabil-
ity.
REGENERATIVE BRAKE
When the brake is applied, the electric
motor used as a generator converts kinet-
ic energy into electric energy.
The regenerative brake works in the fol-
lowing operations.
1. When the accelerator pedal is re- leased, the reduced speed equal to en-
gine braking in a gasoline −fueled ve-
hicle 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.

Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure
to consult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking brake
will not hold the vehicle securely.
Make sure you have a proper freeze
protection of coolant.
Your coolant must contain ethylene−glycol
type coolant for a proper corrosion
protection of aluminum components. Use
“TOYOTA Long Life Coolant” or equivalent.
See 210 page in Section 8 −2 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about −50 °C
( − 58 °F). Do not use more than 70% solu-
tion for better coolant performance.
Check the condition of the auxiliary
battery and cables.
Cold temperatures reduce the capacity of
any auxiliary battery, so it must be in top
shape to provide enough power for winter
starting. Section 8 −3 tells you how to
visually inspect the auxiliary battery. Your
Toyota dealer will be pleased to check the
level of charge. Make sure the engine oil viscosity is
suitable for the cold weather.
See 209 page in Section 8
−2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—he will be pleased to
help.
Keep the door locks from freezing.
Squirt lock de −icer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute as washer fluid be-
cause it may damage your vehicle’s
paint.
