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 0256.
Every 36 000 km (22,500 mi)
.Replace the passenger compartment air
filter. Or every 24 months, whichever
comes first. More frequent passenger
compartment air filter replacement may
be needed if driving in areas with heavy
traffic, poor air quality, high dust levels,
or environmental allergens. Passenger
compartment air filter replacement may
also be needed if there is reduced airflow,
window fogging, or odors. Your GM
dealer can help determine when to
replace the filter.
Every 96 000 km (60,000 mi)
.Replace spark plugs. (2.0L L4 Engine Only.)

struts. Or every 10 years, whichever
comes first. See Gas Strut(s)0267.

.Change rear axle fluid, if equipped with
AWD. Do not directly power wash the
transfer case and/or front/rear axle

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 0258.
