Scheduled Maintenance - Hummer 2007 H2 Owner's Manual

If you want to purchase service information, see
Service Publications Ordering Information on
page 553.
Owner Checks and Services on page 523 tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle in
good condition.
The proper replacement parts, fluids, and
lubricants to use are listed in Recommended
Fluids and Lubricants on page 528 and Normal
Maintenance Replacement Parts on page 530.
When your 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 GM parts.

Scheduled Maintenance

When the CHANGE ENGINE OIL message in the
Driver Information Center (DIC) comes on, it
means that service is required for your vehicle.
See DIC Warnings and Messages on page 226.
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 filter 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.
