Engine Oil
If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center (DIC)
appears, check the engine oil level right away.
For more information, see LOW OIL LEVEL and
LOW OIL PRESSURE underDIC Warnings and
Messages on page 3-63. You should check the engine
oil level regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check the 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 handle is a yellow loop.
SeeEngine Compartment Overview on page 6-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not
do this, the oil dipstick might not show the
actual level.
2. 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.
