When your vehicle is serviced, make sure these

necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message
comes on, it 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, your 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.
