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. See
Ination - Tire Pressure on page 354andLoading
Your Vehicle on page 261for information regarding
proper tire inflation and loading your vehicle. For
instructions on how to remove, install or store a
spare tire, seeRemoving the Flat Tire and Installing
the Spare Tire on page 370andStoring a Flat or
Spare Tire and Tools on page 380.
Your vehicle may have a different size spare tire
than the road tires originally installed on your
vehicle. This spare tire was developed for use
on your vehicle, so it is all right to drive on it.
After installing the spare tire on your vehicle,
you should stop as soon as possible and make
sure the spare tire is correctly inflated. Have
the damaged or flat 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.Do not mix tires and wheels of different sizes,
because they will not fit. Keep your spare tire and
its wheel together. 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 tire in the tire rotation.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes
of heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.
382

When cleaning your vehicle’s interior, only use
cleaners specifically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which
they were not intended. Use glass cleaner only on
glass. Remove any accidental over-spray from
other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the rear window defogger. When cleaning
the glass on your vehicle, use only a soft cloth
and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your
vehicle’s interior, maintain adequate ventilation
by opening your vehicle’s doors and windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.
Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.Do not clean your vehicle using the following
cleaners or techniques:
•Never use a knife or any other sharp object
to remove a soil from any interior surface.
•Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
•Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior
and does not improve the effectiveness of
soil removal.
•Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave a
residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per gallon
(3.78 L) of water is a good guide.
•Do not heavily saturate your upholstery while
cleaning.
•Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.
