Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its
inflation pressure regularly. SeeInflation -- Tire Pressure
on page 5-57andLoading Your Vehicle on page 4-47
for information regarding proper tire inflation and loading
your vehicle. For instruction on how to remove, install
or store a spare tire, seeChanging a Flat Tire on
page 5-65.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inflated. Have the damaged orflat road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst intoflames if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed
space. When you use anything from a container to cleanyour vehicle, be sure to follow the manufacturer’s
warnings and instructions. And always open your doors
or windows when you’re cleaning the inside.
Neveruse these to clean your vehicle:
•Gasoline
•Benzene
•Naphtha
•Carbon Tetrachloride
•Acetone
•Paint Thinner
•Turpentine
•Lacquer Thinner
•Nail Polish Remover
They can all be hazardous–some more than
others–and they can all damage your vehicle, too.
Don’t use any of these unless this manual says you can.
In many uses, these will damage your vehicle:
•Alcohol
•Laundry Soap
•Bleach
•Reducing Agents

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 5-85.
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. SeeChanging a Flat
Tire on page 5-65.
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. SeePart D: Recommended Fluids and
Lubricants on page 6-15.
Automatic Transmission Check
Check the transmission uid level; add if needed. See
Automatic Transmission Fluid on page 5-20.A uid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year

secondary latch, pivots, spring anchor, release
pawl, tailgate hinge, tailgate linkage, tailgate handle
pivot points, latch bolt, fuel door hinge, locks and folding

frequent lubrication may be required when exposed to a
corrosive environment.
