(g)Make sure the safety belt reminder light and all your
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.
(h)Lubricate all key lock cylinders, body door hinges,
hood latch assembly, secondary latch, pivots, spring
anchor, release pawl, fuel door hinge, locks, latches,
and any folding or moving seat hardware. Pickup

tailgate handle pivot points, and latch bolt. Van models:
Lubricate hood hinges and rear compartment hinges.
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.

lters have not been replaced, or if the vehicle has
been driven 20,000 miles (32 000 km) or more since the

FILTER message in the Driver Information Center (DIC)
to tell you when to replace the fuel lter. See Driver
Information Center (DIC) (Pickup Models Only) on
page 3-9 for more information and how to reset the
message after the fuel lter is replaced. If the fuel lter
has not been replaced, or if the vehicle has been driven
15,000 miles (25 000 km) or more since the fuel lter was
last replaced, replace the lter and reset the message.
(k)Inspect shields and underhood insulation for damage
or looseness. Adjust or replace as required. This is a
Noise Emission Control Service. Applicable to vehicles
sold in the United States and recommended for
vehicles sold in Canada.
(l)Check the air intake system installation to assure
that gaskets are properly sealed and that all hose
connections, fasteners, and other components are tight.

properly seated and the cover ts tightly. Tighten
connections and fasteners or replace damaged parts as
necessary. This is a Noise Emission Control Service.
Applicable to vehicles sold in the United States and

excessive wear. Do not lubricate accelerator or
