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 fan and belts.
 Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
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 commercially available coolant additives.
