Checking Engine Oil

It is a good idea to check the engine oil level at each

fuel fill. 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 6‑13

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 this is not done, 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.
