Engine Oil
If your vehicle has a diesel engine, see ªEngine Oilº in
the Diesel Engine Supplement.
If the CHECK OIL LEVEL light appears on the
instrument cluster (except vehicles equipped with the
4.3L engine), it means you need to check your engine oil
level right away.
For more information, see
Driver Information Center
(DIC) on page 3-55.
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. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.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.
