Chevrolet 2009 Corvette Automobile User Manual


 
Scheduled Maintenance
When the CHANGE ENGINE OIL message displays,
service is required for the vehicle. Have the vehicle
serviced as soon as possible within the next 600 miles
(1 000 km). It is possible that, if 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 filter must be changed at least once a year
and at this time the system must be reset. Your dealer/
retailer has trained service technicians who will perform
this work using genuine parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. See Engine Oil Life
System on page 5-26 for information on the Engine
Oil Life System and resetting the system.
When the CHANGE ENGINE OIL message appears,
certain services, checks, and inspections are required.
Required services are described in the following for
“Maintenance I and “Maintenance II.” Generally,
it is recommended that the first service be
Maintenance I, the second service be Maintenance II,
and then alternate Maintenance I and Maintenance II
thereafter. However, in some cases, Maintenance II may
be required more often.
Maintenance I — Use Maintenance I if the message
displays within 10 months since the vehicle was
purchased or Maintenance II was performed.
Maintenance II — Use Maintenance II if the previous
service performed was Maintenance I. Always use
Maintenance II whenever the message displays
10 months or more since the last service or if the
message has not come on at all for one year.
