CAUTION
■ 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 compartment 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 seri-
ous injury.
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 system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
● Do not use any coolant additive.
● IS350/IS300: Do not loosen the coolant res-
ervoir caps or radiator cap while the engine
and radiator are hot. (The radiator cap is
located under the engine cover.)
High temperature steam or coolant could
spray out.
● IS200t: Do not loosen the coolant reservoir
cap or intercooler reservoir cap while the
engine and radiator are hot.
High temperature steam or coolant could
spray out.
