If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center
(DIC) appears, it means you need to check the
engine oil level right away. For more information,
see LOW OIL LEVEL and LOW OIL PRESSURE
underDIC Warnings and Messages on page 206.
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 374
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.
377

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 458.
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 374for 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.
378

What Kind of Engine Oil to Use
Look for two 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. You should 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
also have the starburst
symbol on the
container. This symbol
indicates that the oil
has been certied by the
American Petroleum
Institute (API).
You should 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.
379

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
Standard GM4718M are all you will 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 change
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
Notice:If your vehicle is an XLR-V model, the
engine uses a special oil lter. The use of
any other engine oil lter could lead to lter
failure and result in severe engine damage.
Damage caused by use of the wrong engine oil
lter would not be covered by your new
vehicle warranty.
380

When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL NOW message
in the DIC will come on. SeeDIC Warnings and
Messages on page 206. 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.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 OIL NOW
message in the DIC being turned on, reset
the system.
After the oil has been changed, the CHANGE OIL
NOW message and the oil life indicator must
be reset. To reset the message use the following
procedure:
1. Press the up or down arrow to scroll the DIC
to show OIL LIFE.
2. Once the XXX% ENGINE OIL LIFE menu item
is highlighted, press and hold the RESET
button until the percentage shows 100%.
If the percentage does not return to 100% or if
the CHANGE OIL NOW message comes
back on when you start your vehicle,
the engine oil life system has not reset.
Repeat the procedure.
381

What to Do with Used Oil
Used engine oil contains certain elements that may
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil
from the lter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the
ground, into sewers, or into streams or bodies of
water. Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of your used oil, ask your
dealer, a service station, or a local recycling center
for help.
Supercharger Oil
Because they are technically qualied and have
the proper tools, you should have your dealer
perform this maintenance.
When to Check
SeeAdditional Required Services on page 467for
when the oil level should be checked.
What Kind of Oil to Use
Use only the recommended supercharger oil. See
Recommended Fluids and Lubricants on
page 473.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 374
for the location of the engine air cleaner/lters.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 465for more
information. If you are driving in dusty/dirty
conditions, inspect the lters at each engine oil
change.
382

How to Inspect the Engine Air
Cleaner/Filters
To inspect the air cleaner/lters, remove the lters
from the vehicle and lightly shake the lters to
release loose dust and dirt. If the lters remain
caked with dirt, new lters are required.
To inspect or replace the lters, do the following:
1. Some XLR-V vehicles, have a single piece
black cover that snaps over the entire air
cleaner assembly. For vehicles with this cover,
simply pull it’s left/right sides toward the
outside of the vehicle and lift up to remove
cover. Reinstall the cover when you are
nished inspecting/replacing the lters.2. Move the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the
cover.
3. Lift the front of the cover at an angle and
remove. This is necessary due to the four
tabs located on the rear of the cover.
4. Remove the engine air cleaner/lter element
and any loose debris that might be found in
the air cleaner base.
383

5. Inspect or replace the lter.
6. Repeat the procedure for the second air
cleaner/lter.
Reverse the above procedure to reinstall the
engine air cleaner lter housings.
{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames if
the engine backres. If it is not there and
the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/lter in
place when you are driving.
Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission uid
level. A transmission uid leak is the only
reason for uid loss. If a leak occurs, take the
vehicle to the dealership service department and
have it repaired as soon as possible.
There is a special procedure for checking and
changing the transmission uid. Because
this procedure is difficult, you should have this
done at the dealership service department. Contact
your dealer for additional information or the
procedure can be found in the service manual. To
purchase a service manual, seeService
Publications Ordering Information on page 497.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 473.
