means that service is required for your vehicle.
Have your vehicle serviced 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
engine oil life system may not indicate that vehicle
service is necessary for over a year. However, the
engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your GM Goodwrench
®dealer has GM-trained
service technicians who will perform this work using
genuine GM parts and reset the system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
