(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(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. Lubricate all
hinges and latches, including those for the
body doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove
box door, console door, and any folding 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.

the lter may require replacement more often.(h)Change automatic transaxle uid and lter if
the vehicle is mainly driven under one or more of
these conditions:

binding and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear. Do not
lubricate accelerator or cruise control cables.

(k)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked. Add uid
if needed.
(l)For supercharged engines only: Have your
dealer check the supercharger oil level and
add the proper supercharger oil as needed (or
every 36 months, whichever occurs rst). See
