The air conditioning filter information
label is placed in the glove box as
shown and indicates that a filter has
been installed.
The air conditioning filter prevents dust
from entering the vehicle through the air
conditioning vent.The air conditioning filter is behind the
glove box. The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows begin to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. In dusty areas or areas with heavy
traffic flow, such as inner city or desert
areas, early replacement may be required.
(For scheduled maintenance information,
please refer to the “Scheduled Mainte-
nance Guide” or “Owner ’s Manual Supple-
ment”.)

5. Remove the filter from the filter
case.
6. Inspect the filter on the surface.
If it is dirty, it should be replaced.
When installing the filter and filter
case, keep the arrow pointing up.
INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-
tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.

CAUTION
Never touch, remove or disassemble
high voltage parts and cables.
Touching, removing or disassem-
bling those parts and cables can
cause severe burns or electric
shock that may result in death or
serious injury. For the locations of
high voltage parts and cables, see
“—High voltage components” on
page 6 in Section 1 1.
When the hybrid system is on, keep
hands, clothing, and tools away
from the moving fan. (Removing
rings, watches, and ties is advis-
able.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the radiator is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
When the hybrid system is operat-
ing with the “READY” light on, the
engine may suddenly start in some
cases. When you inspect the engine
compartment, be sure to turn off
the hybrid system.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Brake fluid can harm your hands or
eyes and damage painted surfaces.
If fluid gets on your hands or in
your eyes, flush the affected area
with clean water immediately. If you
still feel uncomfortable with your
hands or eyes, go to the doctor.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the auxiliary battery. It con-
tains poisonous and corrosive
sulfuric acid.

NOTICE
Remember that the auxiliary battery
and ignition cable carry high cur-
rents or voltages. Be careful of ac-
cidentally causing a short circuit.
Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based non silicate,
non amine, non nitrite, and non bo-
rate coolant with long life hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
Do not allow dirt or anything else
to fall through the spark plug holes.
Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not reuse iridium tipped spark
plugs by cleaning or regapping.
Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
