WARNING
■When inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
●If steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot.
●Keep hands and clothing (especially a
tie, a scarf or a muffler) away from the
fans and belts.
Failure to do so may cause the hands
or clothing to be caught, resulting in
serious injury.
●IS350 AWD/IS350/IS300 AWD:
Do not loosen the coolant inlet cap or
coolant reservoir cap while the engine
and radiator are hot. (The coolant inlet
cap is located under the engine cover.)
High temperature steam or coolant
could spray out.
●IS300: Do not loosen the coolant inlet
cap, coolant reservoir cap, or inter-
cooler reservoir cap while the engine
and radiator are hot. High tempera-
ture steam or coolant could spray out.
●IS500: Do not loosen the coolant inlet
cap or coolant reservoir cap while the
engine and radiator are hot. High tem-
perature steam or coolant could spray
out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has
cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can
cause damage to the engine.
■To prevent damage to the cooling sys-
tem
Observe the following precautions:
●Avoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).
