Before closing the hood, be sure all the filler caps
are on.
Then pull the hood down and close it firmly.
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 ªLow Oil Lightº 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 back
of the engine.
NOTE: Do not check the 5.7L engine oil level after the
engine has sat overnight. A higher than normal reading
might be obtained. Check oil level with the oil warm.
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.
