Chevrolet 2009 Colorado, Owner'S Manual

Page: 370 / 418

Owner Checks and Services on page 6-8 tells what
should be checked, when to check it, and what
can easily be done to help keep the vehicle in good
condition.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 6-12 and Maintenance Replacement Parts
on page 6-14. When the vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
When the CHANGE OIL message displays, service
is required for the vehicle. See DIC Warnings and
Messages on page 3-38. 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 5-18 for information on the Engine
Oil Life System and resetting the system.
When the CHANGE 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 that you 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 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.
