Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment frequently to
remove dust and loose dirt. A
canister vacuum with a beater bar in
the nozzle may only be used on oor
carpet and carpeted oor mats. For
soils, always try to remove them rst
with plain water or club soda. Before
cleaning, gently remove as much of
the soil as possible using one of the
following techniques:
For liquids: gently blot the
remaining soil with a paper towel.
Allow the soil to absorb into the
paper towel until no more can be
removed.
For solid dry soils: remove as
much as possible and then
vacuum.
To clean, use the following
instructions:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess
moisture.3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled
area until the cleaning cloth
remains clean.
5. If the soil is not completely
removed, use a mild soap
solution and repeat the cleaning
process that was used with
plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When
a commercial upholstery cleaner or
spot lifter is to be used, test a
small hidden area for colorfastness
rst. If the locally cleaned area
gives any impression that a
ring formation may result, clean the
entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture
from the fabric or carpet.
Leather
A soft cloth dampened with water
can be used to remove dust. If
a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can
be used. Allow the leather to dry
naturally. Do not use heat to
dry. Never use steam to clean
leather. Never use spot lifters or
spot removers on leather. Many
commercial leather cleaners
and coatings that are sold to
preserve and protect leather may
permanently change the appearance
and feel of your leather and are
not recommended. Do not use
silicone or wax-based products, or
those containing organic solvents to
clean your vehicle’s interior
because they can alter the
appearance by increasing the gloss
in a non-uniform manner. Never
use shoe polish on leather.

Foreign materials such as calcium
chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals
from industrial chimneys, etc., can
damage your vehicle’s nish if
they remain on painted surfaces.
Wash the vehicle as soon as
possible. If necessary, use
non-abrasive cleaners that are
marked safe for painted surfaces to
remove foreign matter.
Exterior painted surfaces are subject
to aging, weather and chemical
fallout that can take their toll over a
period of years. You can help to keep
the paint nish looking new by
keeping your vehicle garaged or
covered whenever possible.Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Wash with water or
use chrome polish on chrome or
stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid damaging protective trim,
never use auto or chrome polish,
steam or caustic soap to clean
aluminum. A coating of wax, rubbed
to high polish, is recommended for all
bright metal parts.
Washing Your Vehicle
The best way to preserve your
vehicle’s nish is to keep it clean by
washing it often.
Do not wash the vehicle in direct
sunlight. Use a car washing soap.Notice:Certain cleaners contain
chemicals that can damage the
emblems or nameplates on your
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on your vehicle
or damage may occur and it would
not be covered by the warranty.
Do not use cleaning agents that are
petroleum based or that contain
acid or abrasives, as they can
damage the paint, metal or plastic
on your vehicle. Approved cleaning
products can be obtained from
your dealer/retailer. SeeVehicle
Care/Appearance Materials on
page 9-99. Follow all manufacturers’
directions regarding correct
product usage, necessary safety
precautions and appropriate
disposal of any vehicle care product.

service technicians who will perform
this work using genuine parts and
reset the system.If the engine oil life system is ever
reset accidentally, you must
service your vehicle within
3,000 miles (5 000 km) since your
last service. Remember to reset the

described in the following for
“MaintenanceI” and
“MaintenanceII.” Generally, it is
recommended that your rst service

you alternate MaintenanceIand
MaintenanceIIthereafter. However,
in some cases, MaintenanceII
may be required more often.MaintenanceI— Use
