CAUTION:
{
Performing maintenance work on a vehicle
can be dangerous. In trying to do some jobs,
you can be seriously injured. Do your own
maintenance work only if you have the
required know-how and the proper tools and
equipment for the job. If you have any doubt,
see your GM Goodwrench
qualified technician do the work. See Doing
Your Own Service Work on page 5-4.
Some maintenance services can be complex.
So, unless you are technically qualified and have
the necessary equipment, you should have your
®
GM Goodwrench dealer do these jobs.
When you go to your GM Goodwrench
service needs, you will know that GM-trained and
supported service technicians will perform the work
using genuine GM parts.
