Hummer 2007 H3 - Manual (Page 429)

If you want to purchase service information, see
Service Publications Ordering Information
on page 465.
Owner Checks and Services on page 435 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 440 and Normal
Maintenance Replacement Parts on page 442.
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 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 196. 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.
