Traction battery air vents
Air vents are located in the lower part
of the rear seats to cool the traction
battery. If the vents are covered, the
battery will overheat resulting in re-
duced output performance of the hybrid
system.
You may hear a noise of the cooling fans
from the air vents. For vehicle repairs or maintenance, be
sure to consult your Toyota dealer.
If your vehicle is beyond repair, contact
your Toyota dealer for assistance. Do
not attempt to dispose of your vehicle
by yourself.
CAUTION
Your vehicle contains a sealed Nick-
elMetal hydride battery. If disposed
of improperly, it is hazardous to the
environment and there is a risk of
severe burns and electrical shock that
may result in death or serious injury.
NOTICE

Do not put foreign objects over the
air vent. The traction battery may
be overheated and damaged.
 Do not load a large amount of wa-
ter such as an aquarium into the
vehicle. If water spills over the trac-
tion battery, the battery may be
damaged.
 Do not wet the air vent. This may
adversely affect or damage the trac-
tion battery.
 Clean the air vent regularly to pre-
vent the traction battery from over-
heating.

To turn on the seat heater, push the
switches (“L” switch for the left front
seat and “R” switch for the right front
seat). At this time, the indicator light
will illuminate to indicate the seat heat-
er is operating.
To turn off the seat heater, push the
switch once again.
The key must be in the “ON” position to
operate seat heaters.
CAUTION
Occupants must use caution when op-
erating the seat heater because it
may make them feel too hot or cause
burns at low temperatures (erythema,
varicella). Use extra caution for;
Babies, small children, elderly per-
sons, sick persons or persons with
physical disabilities
Persons who have sensitive skin
Persons who are exhausted
Persons who have taken alcohol or
drugs which induce sleep (sleeping
drug, cold remedy, etc.)
To prevent the seat overheating, do
not use the seat heater with a blan-
ket, cushion, or other insulating ob-
jects which cover the seat.
NOTICE
 Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
 When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.
 To prevent the battery from being
discharged, turn the switch off
when the hybrid system is off.

If the message appears, stop the ve-
hicle as soon as possible and check
the engine compartment. For detailed
instructions, see “If your vehicle over-
heats” on page 343.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
NOTICE
Do not remove the thermostat in
the cooling system as this may
cause the hybrid system to over-
heat. The thermostat is designed to
control the flow of coolant to keep
the temperature of the engine with-
in the specified operating range.
 Continued driving with the message
displayed could result in the over-
heating of the hybrid system.

If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior. Heating
For best results, set controls to:
Fan speed— Any setting except “OFF”
Temperature— To w a r d s WARM
(red zone)
Air intake—FRESH (outside air)
Air flow—FLOOR
Air conditioning—OFF
For quick heating, select recirculated
air for a few minutes. To keep the
windows from fogging, select fresh af-
ter the vehicle interior has been
warmed.
Press the “A/C” button on for dehumidi-
fied heating.
Choose floor/windshield air flow to heat
the vehicle interior while defrosting or
defogging the windshield. Air conditioning
For best results, set controls to:
Fan speed— Any setting except “OFF”
Temperature— To w a r d s COLD
(blue zone)
Air intake—FRESH (outside air)
Air flow—PANEL
Air conditioning—ON
For quick cooling, select recirculated
air for a few minutes.

be sure to secure a wide space,
and watch out for people and ve-
hicles in the neighborhood. Do not
violate any local traffic rules while
performing circling calibration.
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.

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, drive with the windows
open and the back door closed.
Have the cause immediately located
and corrected.
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

DRUMINDISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum−in −disc type
parking brake system. This type of brake
system n eeds bedding −down of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.
Have your Toyota dealer perform the bed-
ding− down.
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary. Driving conditions where the steering
wheel must be turned frequently may
cause an overload to the electric power
steering system. The system will reduce
assistance for sometime to prevent the
power steering from overheating. In this
case, you may feel some resistance when
turning the steering wheel though it is not
a malfunction.
CAUTION
If the “P/S” warning light comes on,
take your vehicle to the Toyota dealer
as soon as possible. In this case, you
may feel the heavy steering wheel
maneuvering. Drive your vehicle while
gripping the steering wheel firmly.
