{Warning
Performing maintenance work can be
dangerous and can cause serious injury.

Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important.
Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the wheel alignment. See
When It Is Time for
New Tires 0301 and
Wheel Replacement 0305.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 330.
.Lubricate body components. See Exterior
Care 0319.
Additional Required Services —Normal
Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed, change engine
oil and filter, and reset oil life system. Or
when the CHANGE ENGINE OIL SOON
message displays, have the engine oil and
filter changed within the next 1 000 km/
600 mi. If driven under the best
conditions, the engine oil life system may
not indicate the need for vehicle service
for up to a year. The engine oil and filter
must be changed at least once a year and
the oil life system must be reset. Your
trained dealer technician can perform this
work. If the engine oil life system is reset
accidentally, service the vehicle within
5 000 km/3,000 mi since the last service.

Service and Maintenance 329
Reset the oil life system when the oil is
changed. SeeEngine Oil Life System
0 267.
.When the REPLACE AT NEXT OIL CHANGE
message displays, the engine air filter
should be replaced at the next engine oil
change. When the REPLACE ENGINE AIR
FILTER SOON message displays, the
engine air filter should be replaced at the
earliest convenience. Reset the engine air
filter life system after the engine air filter
is replaced. See Engine Air Filter Life
System 0268.
Every 36 000 km (22,500 mi)
.Passenger compartment air filter
replacement (or every 24 months,
whichever occurs first). More frequent
replacement may be needed if the vehicle
is driven in areas with heavy traffic, poor
air quality, areas with high dust levels or
are sensitive to environmental allergens.
Filter replacement may also be needed if
you notice reduced airflow, windows
fogging up, or odors. Your local GM
Service location can help you determine
when it is the right time to replace your
filter. Every 96 000 km (60,000 mi)
.Replace spark plugs. Inspect spark plug
wires and/or boots.

struts. Or every 10 years, whichever
comes first. See Gas Strut(s)0279.
Every 240 000 km (150,000 mi)
.Change rear axle fluid, if equipped with
AWD. Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and/
or axles and should be replaced.
.Drain and fill engine cooling system. Or
every six years, whichever comes first.
See Cooling System 0270.

‐ High use commercial vehicles such as
courier delivery vehicles, private
security patrol vehicles, or any vehicles
that operate on a 24–hour basis.
‐ Any vehicle consistently operated in a
high sand or dust environment such as
those used on oil pipelines and similar
applications.
.Vehicles that are regularly used for short
trips of 6 km (4 mi) or less.
The oil life indicator will show you when
to change the oil and filter. Under severe
conditions the indicator may come on
before 12 000 km (7,500 mi).
