2007 KIA Optima Owner's Manual

Maintenance34
7Speed Rating: An alphanumeric
code assigned to a tire indicating the
maximum speed at which a tire can
operate.
Traction: The friction between the
tire and the road surface. The
amount of grip provided.
Tread: The portion of a tire that
comes into contact with the road.
Treadwear Indicators: Narrow
bands, sometimes called "wear
bars," that show across the tread of a
tire when only 2/32 inch of tread
remains.
UTQGS: Uniform Tire Quality
Grading Standards, a tire information
system that provides consumers with
ratings for a tire's traction, tempera-
ture and treadwear. Ratings are
determined by tire manufacturers
using government testing proce-
dures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight : The num-
ber of designated seating positions
multiplied by 150 lbs. (68 kg) plus the
rated cargo and luggage load. Vehicle Maximum Load on the
Tire: Load on an individual tire due to
curb and accessory weight plus
maximum occupant and cargo
weight.
Vehicle Normal Load on the Tire
:
That load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and driving by 2.
Vehicle Placard: A label permanent-
ly attached to a vehicle showing the
original equipment tire size and rec-
ommended inflation pressure.
All season tires Kia specifies all season tires on
some models to provide good per-
formance for use all year round,
including snowy and icy road condi-
tions. All season tires are identified
by ALL SEASON and/or M+S (Mud
and Snow) on the tire sidewall. Snow
tires have better snow traction than
all season tires and may be more
appropriate in some areas.
Summer tires Kia specifies summer tires on some
models to provide superior perform-
ance on dry roads. Summer tire per-
formance is substantially reduced in
snow and ice. Summer tires do not
have the tire traction rating M+S
(Mud and Snow) on the tire side wall.
if you plan to operate your vehicle in
snowy or icy conditions. Kia recom-
mends the use of snow tires or all
season tires on all four wheels.Snow tiresIf you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result.
Snow tires should carry 28 kPa
(4 psi) more air pressure than the
pressure recommended for the stan-
dard tires on the tire label on the dri-
ver's side of the center pillar, or up to
the maximum pressure shown on the
tire sidewall, whichever is less.
Do not drive faster than 120 km/h (75
mph) when your car is equipped with
snow tires.

LUBRICANT SPECIFICATIONSRecommended lubricants To help achieve proper engine and powertrain performance and
durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in
improved fuel economy.
Engine oils labeled Energy Conserving Oil are now available.
Along with other additional benefits, they contribute to fuel
economy by reducing the amount of fuel necessary to over-
come engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer
significant cost and energy savings.
Recommended SAE viscosity number ✽ ✽NOTICEAlways be sure to clean the area around any filler plug, drain
plug, or dipstick before checking or draining any lubricant.
This is especially important in dusty or sandy areas and when
the vehicle is used on unpaved roads. Cleaning the plug and
dipstick areas will prevent dirt and grit from entering the
engine and other mechanisms that could be damaged. Engine oil viscosity (thickness) has an effect on fuel economy
and cold weather operating (starting and oil flow). Lower vis-
cosity engine oils can provide better fuel economy and cold
weather performance, however, higher viscosity engine oils are
required for satisfactory lubrication in hot weather. Using oils of
any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your
vehicle will be operated in before the next oil change. Proceed
to select the recommended oil viscosity from the chart.

7EXTERIOR CARE Exterior general caution It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.Finish maintenanceWashing To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
✽ ✽
NOTICEDo not use strong soap, chemical deter-
gents or hot water, and do not wash the
vehicle in direct sunlight or when the
body of the vehicle is warm. ✽ ✽NOTICE• Water washing in the engine compart-
ment may cause the failure of electri-
cal circuits located in the engine com-
partment.
• Never allow water or other liquids to come in contact with electrical/elec-
tronic components inside the vehicle
as this may damage them.
WaxingWax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.✽ ✽ NOTICE• Wiping dust or dirt off the body with
a dry cloth will scratch the finish.
• Do not use steel wool, abrasive clean- ers, 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 dis-
coloration or paint deterioration.
WARNING
- Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.

Maintenance
Finish damage repair Deep 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.✽ ✽NOTICEIf 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. 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 preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenanceCorrosive materials used for ice and
snow removal and dust control may col-
lect 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, after off-road
driving and at the end of each winter. Pay
special attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. 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.
Aluminum wheel maintenance The aluminum wheels are coated with a
clear protective finish.
 Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
 Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
 Avoid washing the wheels with high- speed car wash brushes.
 Do not use any acid detergent. It may damage and corrode the aluminum
wheels coated with a clear protective
finish.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.

7INTERIOR CARE Interior general precautions Prevent caustic solutions such as per-
fume and cosmetic oil from contacting
the dashboard because they may cause
damage or discoloration. If they do con-
tact the dashboard, wipe them off imme-
diately. See the instructions that follow for
the proper way to clean vinyl.✽ ✽
NOTICENever allow water or other liquids to
come in contact with electrical/electron-
ic components inside the vehicle as this
may damage them.
Cleaning the upholstery and inte-
rior trim Vinyl Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl surfaces with a vinyl cleaner.Fabric Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean with a mild soap solution recom-
mended for upholstery or carpets.
Remove fresh spots immediately with a
fabric spot cleaner. If fresh spots do not
receive immediate attention, the fabric
can be stained and its color can be
affected. Also, its fire-resistant properties
can be reduced if the material is not
properly maintained.✽ ✽NOTICEUsing anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.
Cleaning the lap/shoulder belt
webbing Clean the belt webbing with any mild
soap solution recommended for cleaning
upholstery or carpet. Follow the instruc-
tions provided with the soap. Do not
bleach or re-dye the webbing because
this may weaken it.Cleaning the interior window
glass If the interior glass surfaces of the vehi-
cle become fogged (that is, covered with
an oily, greasy or waxy film), they should
be cleaned with glass cleaner. Follow the
directions on the glass cleaner container.✽ ✽NOTICEDo not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster
grid.
