CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
● Keep hands, clothing, and tools away from the moving fan.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
● Take care because 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 experience discomfort, see a doctor.
● Do not touch the engine compartment when the electric cooling fans are
operating.
The electric cooling fan may keep rotating for about 3 minutes even after
the “POWER” switch is OFF.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the “POWER” switch is OFF when working near
the electric cooling fans or radiator grille.

“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, coolant reservoir cap, drain cock and
water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
■ Coolant selection
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.
U.S.A.: Toyota Super Long Life Coolant is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 °F [-35 °C])
Canada: Toyota Super Long Life Coolant is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 °F [-42 °C])
For more details about coolant, contact your Toyota dealer.

Radiator and condenserCheck the radiators and condenser, and clear any foreign objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicle checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
If the level is low, take your vehi-
cle to a Toyota dealer as soon as
possible. Do not drive your vehi-
cle if the red brake system warn-
ing light is on. Call a Toyota
dealer for assistance.
CAUTION
■When the hybrid system is hot
Do not touch the radiators or condenser as they may be hot and may cause
burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
The electric cooling fan may keep rotating for about 3 minutes after the
“POWER” switch is OFF.
With the “POWER” switch in ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. Be sure the “POWER” switch is OFF when working near the electric
cooling fan or radiator grille.
