Before closing the hood, be sure all the filler caps are
on correctly. To close the hood, hold it up a few inches
from the closed position and let it go so that it has
enough force to engage the hood latch. Pull up on the
hood to be sure it is latched. When you are sure the
hood latch is engaged, then you can latch both hood
side latches.

If the CHECK ENG OIL LEVEL message appears
on the instrument cluster, it means you need to check
your engine oil level right away. For more information,
see "CHECK ENG OIL LEVEL" in the Index.
You should check your engine oil level regularly; this is

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.
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.
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.
The engine oil dipstick has
a loop handle and is located
on the passenger's side of
the vehicle. See "Engine
Compartment Overview"
in the Index for more
information on location.
