x When changing or topping off fluids, make sure that you pour the fluids into the correct reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage.

Engine oil consumption

WARNING
If you must change the engine oil yourself, be sure to take the following precautions:
x Always wear eye protection.
x To reduce the risk of burns from hot engine oil, let the engine cool down completely be-fore beginning.
x When removing the oil drain plug with your fingers, stay as far away as possible. Always keep your forearm parallel to the ground to help prevent hot oil from running down your arm.
x Drain the oil into a container designed for this purpose, one large enough to hold at least the total amount of oil in your engine.
x To reduce the risk of poisoning, never drain the oil into empty food or beverage contain-ers that might mislead someone into drinking from them.
x Engine oil is poisonous and must be stored out of the reach of children.
x Continuous contact with used engine oil is harmful to your skin. Always protect your skin by washing thoroughly with soap and water.
Before changing the oil, first make sure you know where you can properly dispose of the old oil.
