Scheduled Maintenance - Chevrolet 2007 TrailBlazer Owner's Manua

When you go to your GM Goodwrench
your service needs, you will know that GM-trained
and supported service technicians will perform
the work using genuine GM parts.
If you want to purchase service information, see
Service Publications Ordering Information on
page 554.
Owner Checks and Services on page 525 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 529 and Normal
Maintenance Replacement Parts on page 532.
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

dealer for
When the change engine oil light or CHANGE
ENGINE OIL DIC message comes on, it means
that service is required for your vehicle. See
Change Engine Oil Light on page 216 or DIC
Warnings and Messages on page 224. 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 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, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. See Engine Oil Life System on
page 408 for information on the Engine Oil Life
System and resetting the system.
