TIPThe engine oil should be between the
minimum and maximum level marks.
5. If the engine oil is at or below the

cient oil of the recommended type
to raise it to the correct level.
6. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Start the engine, warm it up for several minutes, and then turn it
off.
2. Place an oil pan under the engine to collect the used oil.
3. Remove the engine oil filler cap, the engine oil drain bolt and its
