items can be displayed by pressing the vehicleinformation button:
OIL LIFE REMAINING
If the vehicle has this display, it shows the estimated oillife remaining. If you see 99% OIL LIFE REMAININGon the display, that means that 99% of the current oil liferemains.
When the oil life is depleted, the CHANGE ENGINE OILSOON message will appear on the display. Youshould change the oil as soon as possible. In additionto the engine oil life system monitoring the oil life,additional maintenance is recommended in theMaintenance Schedule in this manual. SeeScheduledMaintenance on page 7-3andEngine Oil on page 6-13.
Remember, you must reset the OIL LIFE yourself aftereach oil change. It will not reset itself. Also, be careful notto reset the OIL LIFE accidentally at any time other thanwhen the oil has just been changed. It cannot be resetaccurately until the next oil change. To reset the engineoil life system, SeeEngine Oil Life System on page 6-16.The display will show 100% when the system is reset.

On vehicles with the Tire Pressure Monitor System(TPMS), this message displays when the pressure inone or more of the vehicle’s tires is low. This messagealso displays LEFT FRONT, RIGHT FRONT, LEFTREAR, or RIGHT REAR to indicate which tire needs tobe checked. The low tire pressure warning light willalso come on. SeeTire Pressure Light on page 4-56.If a tire pressure message appears on the DIC, stop assoon as you can. Have the tire pressures checkedand set to those shown on the Tire Loading Informationlabel. SeeTires on page 6-46,Loading the Vehicleon page 5-18, andInflation - Tire Pressure onpage 6-54. You can receive more than one tire pressuremessage at a time. To read the other messages thatmay have been sent at the same time, press theset/reset button. The DIC also shows the tire pressurevalues. SeeDIC Operation and Displays on page 4-62.

Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended oilswith the starburst symbol that meet GM standards are allthat is needed for good performance and engineprotection.
Engine oil system flushes are not recommended andcould cause engine damage not covered by the vehiclewarranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates whento change the engine oil and filter. This is based onengine revolutions and engine temperature, and not onmileage. Based on driving conditions, the mileage atwhich an oil change is indicated can vary considerably.For the oil life system to work properly, the systemmust be reset every time the oil is changed.
When the system has calculated that oil life has beendiminished, it indicates that an oil change is necessary.A CHANGE ENGINE OIL SOON message in theDriver Information Center (DIC) comes on. Change theoil as soon as possible within the next 600 miles(1 000 km). It is possible that, if driving under the bestconditions, the oil life system might not indicate thatan oil change is necessary for over a year. However, theengine oil and filter must be changed at least once ayear and at this time the system must be reset.Your dealer/retailer has trained people who will performthis work using genuine parts and reset the system.It is also important to check the oil regularly and keep itat the proper level.
If the system is ever reset accidentally, the oil must bechanged at 3,000 miles (5 000 km) since the last oilchange. Remember to reset the oil life system wheneverthe oil is changed.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to changethe engine oil and filter based on vehicle use. Wheneverthe oil is changed, reset the system so it can calculatewhen the next oil change is required. If a situation occurswhere the oil is changed prior to a CHANGE ENGINE OILSOON message in the Driver Information Center (DIC)being turned on, reset the system.
After the oil has been changed, the CHANGE ENGINEOIL SOON message must be reset:
1. Turn the key to the ON/RUN position withoutstarting the engine.
2. Press the INFO button on the Driver InformationCenter (DIC) until OIL LIFE REMAINING isdisplayed. SeeDIC Operation and Displays onpage 4-62.
3. Press and hold the INFO RESET button until 100%is displayed. This resets the oil life indicator.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comesback on when the vehicle is started, the engine oillife system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can beunhealthy for your skin and could even cause cancer.Do not let used oil stay on your skin for very long. Cleanyour skin and nails with soap and water, or a goodhand cleaner. Wash or properly dispose of clothing orrags containing used engine oil. See the manufacturer’swarnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If youchange your own oil, be sure to drain all the oil from thefilter before disposal. Never dispose of oil by putting itin the trash, pouring it on the ground, into sewers, or intostreams or bodies of water. Recycle it by taking it to aplace that collects used oil.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12forthe location of the engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the MaintenanceIIintervals and replace it at the first oil change after each50,000 mile (80 000 km) interval. SeeScheduledMaintenance on page 7-3for more information. If youare driving in dusty/dirty conditions, inspect the filterat each engine oil change.

If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steamcan be seen or heard, the problem may not be tooserious. Sometimes the engine can get a little too hotwhen the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed with no sign ofsteam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature andto the highest fan speed. Open the windows asnecessary.
3. In heavy traffic, let the engine idle in N (Neutral) whilestopped. If it safe to do so, pull off the road, shift toP (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gage is no longer in theoverheat zone or an overheat warning no longer displays,the vehicle can be driven. Continue to drive the vehicleslow for about 10 minutes. Keep a safe vehicle distancefrom the car in front of you. If the warning does not comeback on, continue to drive normally.
If the warning continues, pull over, stop, and park thevehicle right away.
If there is no sign of steam, idle the engine for threeminutes while parked. If the warning is still displayed, turnoff the engine until it cools down. Also, see!OverheatedEngine Protection Operating Mode!next in this section.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and themessage ENGINE OVERHEATED STOP ENGINE isdisplayed, an overheat protection mode which alternatesfiring groups of cylinders helps prevent engine damage.In this mode, you will notice a loss in power andengine performance. This operating mode allows yourvehicle to be driven to a safe place in an emergency.Driving extended miles (km) and/or towing a trailer in theoverheat protection mode should be avoided.
Notice:After driving in the overheated engineprotection operating mode, to avoid engine damage,allow the engine to cool before attempting anyrepair. The engine oil will be severely degraded.Repair the cause of coolant loss, change the oil andreset the oil life system. SeeEngine Oil onpage 6-13.
6-29

Rotation of New Tires
To maintain ride, handling, and performance of thevehicle, it is important that the first rotation service fornew tires be performed when they have 8 000 to13 000 km (5,000 to 8,000 miles). SeeTire Inspectionand Rotation on page 6-62.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. SeeEngine Oil onpage 6-13.An Emission Control Service.
When the Change Engine Oil Soon message displays,service is required for the vehicle as soon as possible,within the next 1 000 km/600 miles. If driving underthe best conditions, the engine oil life system might notindicate the need for vehicle service for more than ayear. The engine oil and filter must be changed at leastonce a year and the oil life system must be reset.Your dealer/retailer has trained service technicians whowill perform this work and reset the system.
If the engine oil life system is reset accidentally, servicethe vehicle within 5 000 km/3,000 miles since the lastservice. Reset the oil life system whenever the oilis changed. SeeEngine Oil Life System on page 6-16.
