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 covered
with 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.

Maintenance

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 than
the normal, the wheel and tire of
the low aspect ratio tire is easi-
er to be damaged. So, follow the
instructions below.
When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driv-
ing, inspect tires and wheels.
When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.
If the tire is impacted, we rec-
ommend that you inspect the
tire condition or contact an
authorized Kia dealer.
To prevent damage to the tire,
inspect the tire condition and
pressure 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 is
allowed 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 to
remove 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 cloth
and 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 neutral
detergent and wipe until contami-
nations do not smear.
Oil
- Remove oil instantly with
absorbable cloth and wipe with
stain remover for natural leather
only.
Chewing gum
- Harden the gum with ice and
remove gradually.CAUTION - Electrical
components
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
CAUTION - Leather
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/alkaline detergents, the
color of the leather may fade or
the surface may get stripped off.
