ating by checking the fan sound and air
flow. If it is difficult to check these, turn the

edly.

peratures.)

7-2. Steps to take in an emergency
Owners Manu-
● Do not touch within the engine com-
partment or get close when the cool-
ing fan is operating. Body parts,
clothes, etc., may get caught and lead
to an accident, resulting in serious
injury. The cooling fan operates auto-
matically at times when the air condi-
tioner is operating and times when the
coolant temperatures are high. Also, it
may operate for several minutes even
after the engine switch is turned off.
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.
Do not loosen the coolant reservoir
●
cap 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 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.).
● Do not use any coolant additive.
