Downloaded from www.Manualslib.com manuals search engine “Section C: Periodic Maintenance
Inspections” explains important inspections that your Chevrolet dealer’s
service department or another qualified
service center should perform.
“Section
D: Recommended Fluids and
Lubricants” lists some products GM
recommends to help keep your vehicle
properly maintained. These products, or
their equivalents, should be used whether
you do the work yourself or have it done.
“Section
E: Maintenance Record”
provides a place for you to record the
maintenance performed on your vehicle.
Whenever any maintenance
is performed,
be sure to write it down in this section.
This will help you determine when your next maintenance should be done. In

Life Monitor. This monitor will
show you when to change the oil
- usually between 3,000 miles
(5 000 km) and 7,500 miles
( 12 500 km) since your last oil
change. Under severe conditions
the indicator may come on before
3,000 miles
(5 000 km). Never
drive your vehicle more than
7,500 miles (12
500 km) or 12
months without an oil change.
The system won’t detect dust in
the oil..
So if you drive in a dusty
area be sure
to change your oil
every 3,000 miles
(5 000 km) or
sooner if the “Change Oil” light
comes on.
