Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
3100 Engine
The engine oil dipstick handle is yellow. The dipstick on
the 2.4L engine is located at the rear of the engine. The
dipstick on the 3100 engine is located on the front of the
engine, behind the fan.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
