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” under
DIC Warnings and Messages on page 232andOil
Pressure Light on page 212. 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 342
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.
346

When to Add Engine Oil
If the oil is below the cross-hatched area at the tip
of the dipstick, you 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 457.
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 342for 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.

What Kind of Engine Oil to Use
Look for three things:
GM4718M
Your vehicle’s engine requires a special oil
meeting GM Standard GM4718M. Oils meeting
this standard may be identied as synthetic.
However, not all synthetic oils will meet
this GM standard. Look for and use only an oil
that meets GM Standard GM4718M.Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
have the starburst
symbol on the
container. This
symbol indicates that
the oil has been
certied by the
American Petroleum
Institute (API).
Look for this on the oil container, and use only
those oils that are identied as meeting GM
Standard GM4718M and have the starburst symbol
on the front of the oil container.
348

Your vehicle’s engine is lled at the factory
with a Mobil 1®synthetic oil, which meets all
requirements for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard
GM4718M may not be available. You can add
substitute oil designated SAE 5W-30 with
the starburst symbol at all temperatures. Substitute
oil not meeting GM Standard GM4718M should
not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
standards are all you need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil changewill be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A change engine oil message in the
Driver Information Center (DIC) will come on.
Change your oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for
over a year. However, your engine oil and lter
must be changed at least once a year and at this
time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system.
It is also important to check your oil regularly and
keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.
349

How to Reset the Engine Oil Life
System and the Oil Life Indicator
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change
your oil prior to a change engine oil message in the
DIC being turned on, reset the system.
After the oil has been changed, the change engine
oil message and the oil life indicator must be
reset. To reset the message and indicator, use one
of the following procedures:
Base Audio System
Press the CLR button located to the right of the
DIC display to acknowledge the change engine oil
message. This will clear the message from the
display and reset it.To reset the oil life indicator, use the following
steps:
1. Press the up or down arrow on the INFO
button located to the right of the DIC
display to access the DIC menu.
2. Once XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the CLR button.
The percentage will return to 100, and
the oil life indicator will be reset. Repeat the
steps if the percentage does not return to 100.
3. Turn the key to OFF.
If the change engine oil message comes back on
when you start your vehicle, the engine oil life
system has not reset. Repeat the procedure.Navigation System
If you have the navigation system, see “Vehicle
Customization” in the Navigation System Manual
for how to reset the oil life indicator.
