Footnotes—Maintenance Schedule
Additional Required Services - Severe
(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 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
0 211.
(4) 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. (5)
Or every five years, whichever comes
first. See Cooling System 0212.
(6) Or every 10 years, whichever comes first.
Inspect for fraying, excessive cracking,
or damage; replace, if needed.
(7) Replace brake fluid every five years. See
Brake Fluid 0218.
(8) Or every 12 months, whichever comes
first. See Wiper Blade Replacement 0220.
(9) Or every 10 years, whichever comes first.
See Gas Strut(s) 0222.
(10) Replace air conditioning desiccant every
seven years.

Additional Maintenance
and Care
Your vehicle is an important investment and
caring for it properly may help to avoid
future costly repairs. To maintain vehicle
performance, additional maintenance
services may be required.
It is recommended that your dealer perform
these services —their trained dealer
technicians know your vehicle best. Your
dealer can also perform a thorough
assessment with a multi-point inspection to
recommend when your vehicle may need
attention.
The following list is intended to explain the
services and conditions to look for that may
indicate services are required.
Battery
The 12-volt battery supplies power to start
the engine and operate any additional
electrical accessories.
.To avoid break-down or failure to start
the vehicle, maintain a battery with full
cranking power.
