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.
