(1) Vehicles with different size front
and rear tires do not have tire
rotation. See Tire Rotation0380.
(2) Or every two years, 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 airf low, window
fogging, or odors. Your GM dealer can
help determine when to replace the

transfer case and/or axles and should
be replaced.
(5) Or every five years, whichever
comes first. See Cooling System0343. (6)
Or every 10 years, whichever
comes first. Inspect for fraying,
