Engine Oil
There is an oil pressure
light in the instrument
cluster and an Oil Pressure
Low Stop Engine message
on the Driver Information
Center (DIC).
If the light and/or message appear, check the engine oil
level right away. For more information, see “Oil Pressure
Low Stop Engine” underDIC Warnings and Messages on
page 3-58andOil Pressure Light on page 3-46. 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 5-14
for 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.
