Engine Oil
If the ENGINE OIL LOW ADD OIL message
appears on the Driver Information Center (DIC),
it means you need to check your engine oil
level right away. For more information, see
ENGINE OIL LOW ADD OIL underDIC Warnings
and Messages on page 252.
You should check your engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It is 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 handle is a yellow loop.
SeeEngine Compartment Overview on page 430
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.

When to Add Engine Oil
If the oil is below the cross-hatched area at the
tip of the dipstick, you will need to add at least
one quart/liter of oil. But you must use the
right kind. This section explains what kind of oil
to use. For engine oil crankcase capacity,
seeCapacities and Specications on page 546.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range, the engine could be damaged.SeeEngine
Compartment Overview
on page 430for the
location of the engine oil
ll cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range. Push the
dipstick all the way back in when you are through.
