6Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fans operate and to check
for coolant leaks from the
radiator or hoses.
The fans operate w hen the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fans are operating by
checking the fan sound and air flow.
If it is difficult to check these, turn
the air conditioning system on and
off repeatedly. (The fans may not
operate in freezing temperatures.)

Stop the engine immediately
and contact your Toyota
dealer.

WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf 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.
●Do not loosen the coolant reser-
voir caps while the engine and
radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the
engine has cooled down suffi-
ciently. 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 precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.
