(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 5-44
and Windshield, Backglass,
and Wiper Blades on page 5-87
for more information.
(e)Make sure the safety belt
reminder light and safety belt
assemblies 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 see Checking the Restraint
Systems on page 1-60.
(f)Lubricate all key lock cylinders,
hood latch assembly, secondary
latch, pivots, spring anchor, release
pawl, rear compartment hinges,
outer endgate handle pivot points,
rear door detent link, rollermechanism, endgate handle pivot
points, latch bolt, fuel door hinge,
locks, and 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.
(g)Check vent hose at transfer
case for kinks and proper
installation.
(h)Change automatic transmission
fluid and filter 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.(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-23
for what to use. Inspect hoses.
Clean radiator, condenser,
pressure cap, and filler neck.
Pressure test the cooling system
and pressure cap.
(j)A fluid loss in any vehicle system
could indicate a problem. Have the
system inspected and repaired
and the fluid level checked. Add fluid
if needed.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
