Engine Oil
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 Light” in the Index.
You should check your engine oil level regularly; this is
an added reminder.
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.

The engine oil dipstick is the yellow loop near the front
of the engine.
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.
