.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 andSpecifications0362.
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, 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 Overview0274
Add enough oil to reach the uppermark on the dipstick. Push thedipstick all the way back in whenthrough.
Selecting the Right Engine Oil
Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.SeeRecommended Fluids andLubricants0358.
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

Viscosity Grade
Use SAE 5W-30 viscosity gradeengine oil.
Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below✓29 °C(✓20 °F), an SAE 0W-30 oil may beused. An oil of this viscosity gradewill provide easier cold starting forthe engine at extremely lowtemperatures. When selecting an oilof the appropriate viscosity grade, itis recommended to select an oil ofthe correct 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 thetrash 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 which
include 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.
When the system has calculatedthat oil life has been diminished, itindicates that an oil change isnecessary. A CHANGE ENGINEOIL SOON message comes on. SeeEngine Oil Messages011 5.Change the oil as soon as possiblewithin the next 1 000 km (600 mi).It is possible that, if driving underthe best conditions, the oil lifesystem might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.
