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.

consumption

1. Check the area around the vehicle be-fore getting in.
2. Adjust seat position, seatback angle, seat cushion angle, seat height, head
restraint height and steering wheel
angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all side doors and back door.
5. Fasten seat belts.
When you get in the vehicle, check
whether the “READY” light is on or
not.
CAUTION
Your vehicle does not produce any
noise or vibration when the vehicle is
ready to be driven with the “READY”
indicator light on. Move your foot
carefully from the brake pedal to the
acceleration pedal when driving.
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces- sories.
3. Put the selector lever in “P”.
4. Depress the brake pedal and hold it to the floor until driving off.
As the hybrid system starts only with the
transmission in the “P” position, put the
selector lever in “P” whenever starting the
system.
Before starting the hybrid system, be sure
to follow the instructions in “(a) Before
starting”.
Starting procedure
With your foot off the accelerator pedal,
turn the key to “START” briefly and firmly.
After a few seconds, the “READY” light
will come on and a beep will sound. If the
ambient temperature is low, such as dur-
ing winter driving conditions, it may take
time until the “READY” light comes on.
The engine may not start even with the
“READY” light on.

You may hear a sound in the engine
compartment when the brake pedal is de-
pressed with the hybrid system off. How-
ever, this does not indicate any trouble.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery under the rear
seats. However, this does not indicate any
trouble.
When the hybrid system is started or
stopped, or while the vehicle is idling, you
may hear a sound coming from the trans-
mission. However, this does not indicate
any trouble.
When applying brakes, you may hear a
sound coming from the regenerative
brakes. However, this does not indicate
any trouble.
When the gasoline engine is started or
stopped with the hybrid system on, you
may feel a vibration. However, this does
not indicate any trouble.
If there is a problem somewhere in the
hybrid system, “CHECK HYBRID SYSTEM”
warning message 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...
See “If your vehicle will not start” on page
338 in Section 4.
CAUTION
Never start the hybrid system from
outside the vehicle, or an accident
may occur. Be sure to sit in the driv-
er seat, then start the system.
NOTICE

If any service reminder indicator
light comes on or warning message
appears on the multiinformation
display (see page 144 and page 155
for details) or the 12 volt battery is
disconnected, the hybrid system
may not start. In that case, turn the
ignition on again. If the “READY”
light does not come on, contact
your Toyota dealer.
 When you start the hybrid system
at a lower outside temperature, it
may take longer before the blinking
“READY” light changes to constant
on.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp− edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P”. If necessary, block the
wheels.
Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.

Take all necessary safety measures
to ensure that water damage to the
hybrid battery, hybrid system or
other components does not occur.
Water entering the engine compart-
ment may cause severe damage to
the hybrid system. Water entering
the interior may cause the hybrid
battery stowed under the rear seats
to short circuit.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the transaxle case, reducing the
gear oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
 Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the “Scheduled Main-
tenance Guide” or “Owner’s Manual
Supplement”.Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non −silicate, non −amine, non −nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the coolant level” on page
388 in Section 7 −2 for details of coolant
type selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Check the status of the hybrid battery.
See page 4 for the status of the hybrid
battery. If the hybrid battery is discharged,
the hybrid system will not start up.
Check the condition of the 12 volt bat-
tery and cables.
Cold temperatures lower the performance
of the 12 volt battery, so it must be in top
shape to provide enough power for winter
starting. Section 7 −3 tells you how to
visually inspect the 12 volt battery. Your
Toyota dealer and most service stations
will be pleased to check the charge level.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 386 in Section 7 −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—they 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.

Before making these checks, make sure
you have sufficient fuel and that you have
followed the correct starting procedure giv-
en in “How to start the hybrid system” on
page 324 in Section 3. If your vehicle is
equipped with the engine immobilizer sys-
tem, also check whether the other keys
will start the hybrid system. If they work,
your key may be broken. Have the key
checked at your Toyota dealer. If none of
your keys work, there may be a malfunc-
tion in the immobilizer system. Call your
Toyota dealer. (See “Keys (with engine
immobilizer system)” on page 22 in Sec-
tion 1−2.)
If the instrument cluster dims or the
instrument cluster display turns off
with the ignition on... 1. Check that the 12 volt battery terminals are tight and clean.
2. If the 12 volt battery terminals are O.K., the 12 volt battery is discharged.
You may try jump starting. See “(b)
Jump starting” on page 338 for further
instructions.
NOTICE
Hybrid vehicles cannot be push
started.
If the instrument cluster displays with
normal brightness levels with the igni-
tion on...
The hybrid system may be faulty. Contact
your Toyota dealer. If the 12 volt battery is discharged, the
hybrid system can be started by jump
starting. Depending on the vehicle con-
dition, however, the hybrid system may
not start.
To avoid serious injury and damage to
your vehicle which might result from an
explosion of the battery, acid burns,
electrical burns, or damaged electronic
components, follow instructions careful-
ly.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.
CAUTION
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses when
jump starting, and avoid spilling
acid on your skin, clothing, or ve-
hicle.
