Engine Oil
If the OIL LEVEL LOW ADD OIL message
appears in the Driver Information Center (DIC), it
means you need to check the engine oil level
right away. For more information, see
DIC
Warnings and Messages on page 221 . 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.
See
Engine Compartment Overview on page 334
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.
