(1) 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 airflow, window
fogging, or odors. Your GM dealer
can help determine when to replace
the filter.
(2) Visually check all fuel and vapor
lines and hoses for proper
attachment, connection, routing, and
condition.
(3) Or as indicated by the Driver
Information Center (DIC) or
two years whichever comes first.
The fuel filter may need to be
replaced more often based on
biodiesel usage, driving in climates
with severe dust, off-road driving,
or towing a trailer for extended
periods. (4)
Or every four years, whichever
comes first. If driving in dusty
conditions, inspect the filter at each
oil change or more often as needed.
See Engine Air Cleaner/Filter 0288.
(5) 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.
(6) Or every five years, whichever
comes first. See Cooling System
0 290.
(7) Or every 10 years, whichever
comes first. Inspect for fraying,
excessive cracking, or damage;
replace, if needed.
(8) Replace brake fluid every five
years. See Brake Fluid 0297.
(9) Or every 12 months, whichever
comes first. See Wiper Blade
Replacement 0300.
(10) Or every 10 years, whichever
comes first. See Gas Strut(s)0302. (11)
Replace air conditioning
desiccant every seven years.
