5-2. Steps to take in an emergency
CAUTION
■
To prevent an accident or injury when inspecting under the hood of
your vehicle
●
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, caus-
ing serious injuries such as burns.
●
Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
●
Do not loosen the radiator cap or the coolant reservoir cap while the
engine and radiator are hot. Serious injury, such as burns, may result from
hot coolant and steam released under pressure.
NOTICE
■
When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. 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 commercially available coolant additives.
