(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine parts as needed. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap and cleaning the outside of the
radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 344 and Windshield
and Wiper Blades on page 387 for more
information.
(e)Make sure the safety belt reminder light and
all belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.(f)Lubricate all key lock cylinders, hood hinges,
hood prop rod pivot, hood latch assembly,
secondary latch, pivots, spring anchor, release
pawl, rear compartment hinges, latches, locks, fuel
door hinge, and any moving seat hardware. More
frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease
on weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Vehicles with Gross Vehicle Weight Rating
(GVWR) above 10,000 lbs (4 536 kg) only: Inspect
shields for damage or looseness. Adjust or
replace as required. This is a Noise Emission

if the vehicle is mainly driven under one or
more of these conditions:
-In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
-In hilly or mountainous terrain.
-When doing frequent trailer towing.
-Uses such as found in taxi, police,
or delivery service.

Your GM vehicle has a number of sophisticated

vehicle’s performance and how it is driven.
For example, your vehicle uses computer modules
to monitor and control engine and transmission
performance, to monitor the conditions for
airbag deployment and deploy airbags in a crash
and, if so equipped, to provide anti-lock braking
to help the driver control the vehicle. These
modules may store data to help your dealer/retailer
technician service your vehicle. Some modules
may also store data about how you operate
the vehicle, such as rate of fuel consumption
or average speed. These modules may also retain
the owner’s personal preferences, such as radio
pre-sets, seat positions, and temperature settings.
