Engine Oil

Checking Engine Oil
It is a good idea to check your engine oil every time
you get fuel. In order to get an accurate reading, the
oil must be warm and the vehicle must be on level
ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12 for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. 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.
