Scheduled Maintenance Service
Introduction
The following information covers the maintenance required for these
vehicles. This maintenance is required to retain the safety, dependability,
and emission control performance of these vehicles.
Important: Keep the engine oil at the proper level and change the oil as recommended.
Proper vehicle maintenance keeps the vehicle in good operating condition and
directly helps the environment. Improper vehicle maintenance or the removal
of important components can significantly affect the quality of the air we
breathe. Improper fluid levels or improper tire inflation can increase the
level of emissions from these vehicles. Help protect the environment by keeping
these vehicles in proper operating condition. Perform ALL recommended maintenance
procedures.
Using the Maintenance Schedule
GM wants to help keep these vehicles in good working condition. The
customers operate their vehicles under a variety of road and off-road conditions.
These conditions may require more frequent checks than what you find listed
in the Maintenance Schedules. Review the schedules while determining the customer's
driving habits. The vehicle will be properly maintained if these conditions
are considered.
In order to locate the proper fluids and lubricants, refer to LINK Recommended
Fluids and Lubricants. Use the proper fluids and lubricants whenever servicing
these vehicles.
The schedules are for vehicles that satisfy the following conditions:
| • | Vehicles that carry passengers and cargo within the recommended
limits. Refer to LINK Vehicle Certification Label. |
| • | Vehicles that are driven on reasonable road surfaces within the
legal driving limits. |
| • | Vehicles that use the recommended unleaded fuel. |
City Schedule Definition
Follow Maintenance City Schedule if any one of these conditions are
applicable:
| • | Most trips are less than 8 to 16 km (5 to 10 miles). This
is particularly important when outside temperatures are below freezing. |
| • | Most trips include extensive idling (such as frequent driving
in stop and go traffic). |
| • | The vehicle is frequently operated in dusty areas or off-road. |
| • | The vehicle frequently tows a trailer or uses a carrier on top. |
Refer to LINK Maintenance Schedule I.

Footnotes
* The California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission warranty
or limit recall liability prior to the completion of the vehicle useful life.
We do urge, however, that ALL recommended maintenance be recorded.
** For Drive Axle Service, perform the following:
| • | Dana -- Drain the fluid and refill at the first engine oil
change. Change the lubricant every 166 000 km (100,000 miles)
or 24 months for normal use. If driving in dusty, sandy or wet conditions,
or towing a trailer, change the lubricant every 42 000 km (25,000 miles)
or 6 months. |
| • | Eaton -- Drain the fluid and refill at 8 000 km
(5,000 miles) initially. Change the lubricant every 166 000 km
(100,000 miles) thereafter for normal use. For more severe use, change
the lubricant every 64 000 km (40,000 miles). |
| • | More frequent lubrication may be required for heavy-duty use. |
