2006 KIA Optima wheel

TREAD WEARThe tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use. Variations in driving habits,
service practices and differences in road
characteristics and climate may
significantly affect performance.TRACTION - A, B AND CThe traction grades, from highest to
lowest, are A, B and C, and they
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
TEMPERATURE-A, B AND CThe temperature grades are A (the
highest), B and C, representing the tire’s
resistance to generate heat and to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperatures can cause the material
of the tire to degenerate and reduce tire
life, and excessive temperature can lead
to sudden tire failure. Grade C
corresponds to a level of performance
that all passenger vehicle tires must meet
under the Canadian Motor Vehicle
Safety Standard No. 109: Grades A and
B represent higher levels of performance
on the laboratory test wheel than the
maximum required by law.
WARNING - Tire
Temperature
The temperature grade for a tire
is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden tire
failure. This can cause loss of
vehicle control and death or
personal injury.

MAINTENANCE
7-32WHEEL REPLACEMENTWhen replacing the metal wheels for any
reason, make sure the new wheels are
equivalent to the original factory units in
diameter, rim width and offset.
BULB REPLACEMENTHEADLIGHT BULB
REPLACEMENT
1. Remove the headlight bulb cover by
turning it counterclockwise.
2. Disconnect the headlight bulb
electrical connector.

CAUTION
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire
clearance, snow chain clearance,
speedometer calibration, headlight
aim and bumper height.
WARNING - Halogen
Bulbs

Wear eye protection when
changing a bulb. Allow the
bulb to cool before handling it.
Halogen bulbs contain
pressurized gas. If broken, a
halogen bulb will explode and
will produce flying pieces of
glass.
Always handle halogen bulbs
carefully to avoid scratches
and abrasions. If the bulbs
are lit, avoid contact with
liquids. Never touch the
glass with bare hands.
Residual oil may cause the
bulb to overheat and burst
when lit. A bulb should be
operated only when installed
in the headlight assembly.
If a bulb becomes damaged
or cracked, replace it
immediately and carefully
dispose it.

FINISH DAMAGE REPAIRDeep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major repair
expense.
BRIGHT-METAL MAINTENANCE• To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
• To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome
preservative and rub to a high luster.
• During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
UNDERBODY
MAINTENANCECorrosive materials used for ice and
snow removal or dust control may
collect on the underbody. If these
materials are not removed, accelerated
rusting can occur on underbody parts,
such as the fuel lines, frame, floor pan
and exhaust system, even though they
have been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month and especially
at the end of each winter. Pay special
attention to these areas because it is
difficult to see all the mud and dirt. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting. It will do more harm than good
to wet down the road grime without
removing it.
✻
NOTICE
• Wiping dust or dirt off the body
with a dry cloth will scratch the
inish.
• Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint
deterioration.
✻
NOTICE
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body shop
applies anti-corrosion materials to
the parts repaired or replaced.

MAINTENANCE
7-40ALUMINUM WHEEL
MAINTENANCEThe aluminum wheels are coated with a
clear protective finish.
• Do not use any abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
• Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
• Avoid washing the wheels with high-
speed car wash brushes.
INTERIOR CAREINTERIOR GENERAL
PRECAUTIONSPrevent caustic solutions such as
perfume and cosmetic oil from
contacting the dashboard; they may
cause damage or discoloration. If they do
contact the dashboard, wipe them off
immediately.UPHOLSTERY AND
INTERIOR TRIM CLEANINGVINYLFirst, remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Then, clean vinyl surfaces with a
vinyl cleaner.
FABRICFirst, remove dust and loose dirt from
fabric with a whisk broom or vacuum
cleaner. Then, clean with a mild soap
solution recommended for upholstery or
carpets. Remove fresh spots immediately
with a fabric spot cleaner. If a fresh spot
do not receive immediate attention, the
fabric may be stained and its color can be
affected. Also, its fire-resistant properties
may be reduced if the material is not
properly maintained.
CAUTION
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water.
CAUTION
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.
