Checking Engine Oil
Check the engine oil level regularly(every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0354for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center(DIC) message displays, check theoil level.
Follow these guidelines:
.To g e t a n a c c u r a t e r e a d i n g , p a r kthe vehicle on level ground.Check the engine oil level afterthe engine has been off for atleast two hours. Checking theengine oil level on steep gradesor too soon after engine shutoffcan result in incorrect readings.Accuracy improves when
checking a cold engine prior tostarting. Remove the dipstickand check the level.
.If unable to wait two hours, theengine must be off for at least15 minutes if the engine iswarm, or at least 30 minutes ifthe engine is not warm. Pull outthe dipstick, wipe it with a cleanpaper towel or cloth, then push itback in all the way. Remove itagain, keeping the tip down, andcheck the level.
When to Add Engine Oil
If the oil is below the cross-hatchedarea at the tip of the dipstick andthe engine has been off for at least15 minutes, add 1 L (1 qt) of therecommended oil and then recheckthe level. See“Selecting the RightEngine Oil”later in this section foran explanation of what kind of oil to
use. For engine oil crankcasecapacity, seeCapacities andSpecifications0468.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., 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. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
SeeEngine Compartment Overview0354for the location of the engineoil fill cap.

Vehicle Care 361
Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.
Selecting the Right Engine Oil
Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.SeeRecommended Fluids andLubricants0462.
Specification
Ask for and use engine oils thatmeet the dexos1™specification.Engine oils that have beenapproved by GM as meeting thedexos1 specification are markedwith the dexos1 approved logo. Seewww.gmdexos.com.
Caution
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use SAE 0W-20 viscosity grade forthe 5.3L and 6.2L V8 engines. UseSAE 5W-30 viscosity grade for the4.3L V6, and 6.0L V8 engines.
Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below✓29 °C(✓20 °F), an SAE 0W-30 oil may beused in the 4.3L or 6.0L engine. Anoil of this viscosity grade will provideeasier cold starting for the engine atextremely low temperatures.
When selecting an oil of theappropriate viscosity grade, it isrecommended to select an oil of thecorrect specification. See“Specification”earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. Therecommended oils meeting thedexos1 specification are all that isneeded for good performance andengine protection.
Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.
What to Do with Used Oil
Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.
Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in the

trash or pouring it on the ground,into sewers, or into streams orbodies of water. Recycle it by takingit to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. Forthe oil life system to work properly,the system must be reset every timethe oil is changed.
On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes on toindicate that an oil change isnecessary. SeeEngine OilMessages0152.Changetheoilassoon as possible within the next1000km (600mi). It is possible that,if driving under the best conditions,
the oil life system might indicate thatan oil change is not necessary forup to a year. The engine oil andfilter must be changed at least onceayearand,atthistime,thesystemmust be reset. For vehicles withoutthe CHANGE ENGINE OIL SOONmessage, an oil change is neededwhen the OIL LIFE REMAININGpercentage is near 0%. Your dealerhas trained service people who willperform this work and reset thesystem. It is also important to checkthe oil regularly over the course ofan oil drain interval and keep it atthe proper level.
If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. Always reset the
engine oil life to 100% after every oilchange. It will not reset itself. Toreset the engine oil life system:
1. Display the OIL LIFEREMAINING on the DIC. If thevehicle does not have DICbuttons, the vehicle must be inP(Park)toaccessthisdisplay.SeeDriver Information Center(DIC) (Base Level)0145orDriver Information Center (DIC)(Uplevel)0147.
2. Press and holdV,orthetrip
odometer reset stem if thevehicle does not have DICbuttons, for several seconds.The oil life will changeto 100%.
The oil life system can also be resetas follows:
1. Turn the ignition to ON/RUNwith the engine off.
2. Fully press the acceleratorpedal slowly three times withinfive seconds.

When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, then use the followingchecking procedures to check thefluid level. However, if there is alarge leak, then it may be necessaryto have the vehicle towed to a
dealer service department and haveit repaired before driving the vehiclefurther.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the
automatic transmission fluid listed

damage the transmission. Too
much can mean that some of the
fluid could come out and fall on
hot engine parts or exhaust
system parts, starting a fire. Too
little fluid could cause the
transmission to overheat. Be sure
to get an accurate reading if
checking the transmission fluid.
Before checking the fluid level,prepare the vehicle:
1. Start the engine and park thevehicle on a level surface.Keep the engine running.
2. Apply the parking brake andplace the shift lever in P (Park).
3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about

three seconds in each range.Then, move the shift lever backto P (Park).
4. Allow the engine to idle (500–800 rpm) for at leastone minute. Slowly release thebrake pedal.
5. Keep the engine running andcheck the transmission fluidtemperature on the DriverInformation Center (DIC). SeeDriver Information Center (DIC)(Base Level)0145orDriverInformation Center (DIC)(Uplevel)0147.
6. Using the transmission fluidtemperature reading, determineand perform the appropriatecheck procedure. If thetransmission fluid temperaturereading is not within therequired temperature ranges,allow the vehicle to cool,or operate the vehicle until theappropriate transmission fluidtemperature is reached.
Cold Check Procedure
Use this procedure only as areference to determine if thetransmission has enough fluid to beoperated safely until a hot checkprocedure can be made. The hotcheck procedure is the mostaccurate method to check the fluidlevel. Perform the hot checkprocedure at the first opportunity.Use this cold check procedure tocheck fluid level when thetransmission temperature isbetween 27 °C and 32 °C (80 °F and90 °F).
1. Locate the transmissiondipstick at the rear of theengine compartment, on thepassenger side of the vehicle.
SeeEngine CompartmentOverview0354.
2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.
3. Install the dipstick by pushing itback in all the way; waitthree seconds, and then pull itback out again.
4. Check both sides of thedipstick and read the lowerlevel. Repeat the checkprocedure to verify the reading.
5. If the fluid level is below theCOLD check band, add onlyenough fluid as necessary tobring the level into the COLDband. It does not take muchfluid, generally less than 0.5 L(1 pt). Do not overfill.

6. Perform a hot check at the firstopportunity after thetransmission reaches a normaloperating temperature between71 °C to 93 °C (160 °F to200 °F).
7. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.
Hot Check Procedure
Use this procedure to check thetransmission fluid level when thetransmission fluid temperature isbetween 71 °C and 93 °C (160 °Fand 200 °F).
The hot check is the most accuratemethod to check the fluid level. Thehot check should be performed atthe first opportunity in order to verifythe cold check. The fluid level risesas fluid temperature increases, so itis important to ensure thetransmission temperature is withinrange.
