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 11.
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.

If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Toyota dealer.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator or con-
denser when they may be hot after
driving.
NOTICE
To prevent damage to the radiators
and condenser, do not perform the
work by yourself.To check the fluid level, simply look at
the seethrough reservoir. The level
should be between the “MAX” and
“MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear or
when the fluid level in the accumulator is
high.
If the level is low, take your vehicle to
a Toyota dealer as soon as possible. Do
not drive your vehicle if the red brake
system warning light is on. Call a
Toyota dealer for assistance. If the fluid level goes down soon after
your vehicle is serviced, it may indicate
a serious mechanical problem. Have
your vehicle checked by a Toyota deal-
er.
CAUTION
Brake fluid can harm your hands or
eyes. 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.
NOTICE
If brake fluid is spilled on the vehicle,
be sure to wipe it off to prevent dam-
age to parts or paint.
