If the LOW OIL light on
the instrument panel comes
on, it means you need to
check your engine oil
level right away.
For more information, see "Low Oil Level Light" in the
Index. You should check your engine oil level regularly;

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 the yellow loop near
the front of the engine.
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.
