Checking Engine Oil

It's 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.

you need to check your
engine oil level right away.

The engine oil dipstick has a yellow ring handle and is
located in the engine compartment on the passenger's
side of the vehicle. See "Engine Compartment
Overview" in the Index for more information
on location.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
