Checking Things Under
the Hood
{CAUTION:
Things that burn can get on hot engine parts
and start a ®re. These include liquids like fuel,
oil, coolant, brake ¯uid, windshield washer and
other ¯uids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the handle located
inside the vehicle to
the lower left of
the steering wheel.

center of the grill.
3. Lift the hood.

At Least Twice a Year
Restraint System Check
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 air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-96.
Spare Tire Check
At least twice a year, after the monthly in¯ation check of
the spare tire determines that the spare is in¯ated to the
correct tire in¯ation pressure, make sure that the spare
tire is stored securely. Push, pull, and then try to rotate or
turn the tire. If it moves, use the wheel wrench/ratchet to
tighten the cable. See
Changing a Flat Tire on page 5-76.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-17.
Automatic Transmission Check
Check the transmission ¯uid level; add if needed.
SeeAutomatic Transmission Fluid on page 5-21.
A ¯uid loss may indicate a problem. Check the system
and repair if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all hood latch assembly, secondary latch,
pivots, spring anchor, release pawl, rear compartment
hinges, outer tailgate handle pivot points, latch bolt,
fuel door hinge and folding seat hardware. Part D tells
you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
