Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and defini-
tions
Air Pressure:
The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, dual clutch trans-
mission, power seats, and air condi-
tioning.
Aspect Ratio: The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire: A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread.

Maintenance
Occupant Distribution:Designated
seating positions.
Outward Facing Sidewall: The side
of a asymmetrical tire that has a par-
ticular side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.
Passenger (P-Metric) Tire: A tire
used on passenger cars and some
light duty trucks and multipurpose
vehicles.
Ply: A layer of rubber-coated parallel
cords
Pneumatic tire: A mechanical
device made of rubber, chemicals,
fabric and steel or other materials,
that, when mounted on an automo-
tive wheel, provides the traction and
contains the gas or fluid that sustains
the load. Production options weight:
The
combined weight of installed regular
production options weighing over 5
lb.(2.3 kg) in excess of the standard
items which they replace, not previ-
ously considered in curb weight or
accessory weight, including heavy
duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
Recommended Inflation Pressure:
Vehicle manufacturer's recommend-
ed tire inflation pressure and shown
on the tire placard.
Radial Ply Tire: A pneumatic tire in
which the ply cords that extend to the
beads are laid at 90 degrees to the
centerline of the tread.
Rim: A metal support for a tire and
upon which the tire beads are seat-
ed.
Sidewall: The portion of a tire
between the tread and the bead. Speed 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 1/16 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. (68kg) 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:
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.
WARNING
Do not use summer tires at tem-
peratures below 45°F (7°C) or
when driving on snow or ice. At
temperatures below 45°F (7°C),
summer tires can lose elastici-
ty, and therefore traction and
braking power as well. Change
the tires on your vehicle to win-
ter or all-weather tires of the
same size as the standard tires
of the vehicle. Both types of
tires are identified by the M+S
(Mud and Snow) marking. Using
summer tires at very cold tem-
peratures could cause cracks to
form, thereby damaging the
tires permanently.

Maintenance
Snow tires
If 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 4 psi (28
kPa) 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 75 mph (120
km/h) when your vehicle is equipped
with snow tires.
Tire chains
Tire chains, if necessary, should be
installed on the front wheels.
Be sure that the chains are installed
in accordance with the manufactur-
er's instructions.
To minimize tire and chain wear, do
not continue to use tire chains when
they are no longer needed.
When driving on roads coveredwith snow or ice, drive at less than
20 mph (30 km/h).
Use the SAE “S” class or wire chains.
If you hear noise caused by chains contacting the body, retighten the
chain to avoid contact with the
vehicle body.
To prevent body damage, retighten the chains after driving 0.3~0.6
miles (0.5~1.0 km).
Do not use tire chains on vehicles equipped with aluminum wheels.
In unavoidable circumstances, use
a wire type chain.
Use wire chains less than 0.47 inches (12 mm) to prevent damage
to the chain’s connection.
Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are
of belted construction and are select-
ed to complement the ride and han-
dling characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity as bias-ply or bias
belted tires of the same size and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: identical radial-ply tires should
always be used as a set of four.

Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval shown in this section
to achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for sporty looks.
Because the low aspect ratio tires
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tires.
CAUTION
Because the sidewall of the low
aspect ratio tire is shorter thanthe normal, the wheel and tire ofthe low aspect ratio tire is easi-er to be damaged. So, follow theinstructions below.
When driving on a rough road or off road, drive cautiouslybecause tires and wheels maybe damaged. And after driv-ing, inspect tires and wheels.
When passing over a pothole, speed bump, manhole, or curbstone, drive slowly so that thetires and wheels are not dam-aged.
If the tire is impacted, we rec- ommend that you inspect thetire condition or contact anauthorized Kia dealer.
To prevent damage to the tire, inspect the tire condition andpressure every 1,900 miles(3,000 km).

Aluminum wheel maintenance
The 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 the finish.
Clean the wheel when it has cooled.
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 vehicle wash brushes.
Do not use any alkaline or acid detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, we produce vehicles of
the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner's
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that isallowed to accumulate underneath
the vehicle.
Removal of paint or protective coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.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 forward
speed.

Maintenance
Taking care of leather seats
Vacuum the seat periodically toremove dust and sand on the seat.
It will prevent abrasion or damage of
the leather and maintain its quality.
Wipe the natural leather seat cover often with dry or soft cloth.
Sufficient use of a leather protec- tive may prevent abrasion of the
cover and helps maintain the color.
Be sure to read the instructions
and consult a specialist when
using leather coating or protective
agents.
Leather with bright colors(beige, cream beige) is easily contaminat-
ed and clear in appearance. Clean
the seats frequently.
Avoid wiping with wet cloth. It may cause the surface to crack.
Cleaning the leather seats
Remove all contaminations instant-ly. Refer to instructions below for
removal of each contaminant.
Cosmetic products(sunscreen, foundation, etc.)
- Apply cleansing cream on a clothand wipe the contaminated point.
Wipe off the cream with a wet
cloth and remove water with a dry
cloth.
Beverages(coffee, soft drink, etc.) - Apply a small amount of neutraldetergent and wipe until contami-
nations do not smear.
Oil - Remove oil instantly withabsorbable cloth and wipe with
stain remover for natural leather
only.
Chewing gum - Harden the gum with ice andremove gradually.CAUTION - Electrical
components
Never allow water or other liq-uids to come in contact withelectrical/electronic compo-nents inside the vehicle as thismay damage them.
CAUTION - Leather
When cleaning leather products(steering wheel, seats etc.), useneutral detergents or low alco-hol content solutions. If you usehigh alcohol content solutionsor acid/alkaline detergents, thecolor of the leather may fade orthe surface may get stripped off.
