voir caps, drain cock and water pump.
If you cannot find a leak, have any

WARNING
■ When the hybrid system is hot
Do not remove the engine/power con-
trol unit coolant reservoir caps.
The cooling system may be under
pressure and may spray hot coolant if
the cap is removed, causing serious
injuries, such as burns.
NOTICE
■ When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be
used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant
label.
■ If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.
