Chevrolet 2009 HHR Automobile User Manual


 
Scheduled Maintenance
When the CHANGE OIL SOON 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 5-21 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL SOON 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 CHANGE
OIL SOON 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 CHANGE OIL SOON
message displays 10 months or more since the last
service or if the message has not come on at all for
one year.
