Roof rack (if equipped)
If the vehicle has a roof rack, you can
load cargo on top of your vehicle.
Crossbars and fixing components
can be installed on the roof rack
when carrying cargo. Those may be
obtained from an authorized Kia
dealer.
✽ ✽
NOTICE
• The crossbars (if equipped) should
be placed in the proper load carry-
ing positions prior to placing items
onto the roof rack.
• If the vehicle is equipped with a
sunroof, be sure not to position
cargo onto the roof rack in such a
way that it could interfere with
sunroof operation.
• When the roof rack is not being
used to carry cargo, the crossbars
may need to be repositioned if
wind noise is detected.
EXTERIOR FEATURES
CAUTION - Loading Roof
Rack
When carrying cargo on the
roof rack, take the necessary
precautions to make sure the
cargo does not damage the
roof of the vehicle.
When carrying large objects
on the roof rack, make sure
they do not exceed the overall
roof length or width.
When you are carrying cargo
on the roof rack, do not oper-
ate the sunroof (if equipped).
This can damage the sunroof.

Detecting Sensor
The rear corner radars are the sen-
sors inside the rear bumper for
detecting the side/rear areas. Always
keep the rear bumper clean for prop-
er operation of the system.
CAUTION
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
the warning light on the out-
side rearview mirror illumi-
nates or there is a warning
alarm.
Playing the vehicle audio sys-
tem at high volume may offset
Blind-Spot Collision Warning
system warning sounds.
The warning of the Blind-Spot
Collision Warning system may
not sound while other sys-
tem's warning sounds.
ODEP059158
■Rear corner radarsCAUTION
The system may not work
properly when the bumper has
been damaged, or if the rear
bumper has been replaced or
repaired.
The sensing range differs some-
what according to the width of
the road. When the road is nar-
row, the system may detect
other vehicles in the next lane.
The system may turn off due to
strong electromagnetic waves.
Always keep the sensor or near
the sensor clean.
NEVER arbitrarily disassem-
ble the sensor component nor
apply any impact on the sen-
sor component.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the system
may not operate correctly. In
this case, a warning message
may not be displayed.

Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1.6 mm (1/16 inch)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽

NOTICE
• We recommend that when replac-
ing tires, use the same which were
originally supplied with the vehi-
cle. If not, driving performance
could be altered.
• When replacing tires (or wheels),
it is recommended to replace the
two front or two rear tires (or
wheels) as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
Wheel replacement
When 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.
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 clear-
ance, snow chain clearance,
speedometer and odometer calibra-
tion, headlight aim and bumper
height.

2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
P205/55R16 89H
P - Applicable vehicle type (tires
marked with the prefix “P’’ are
intended for use on passenger
vehicles or light trucks; however,
not all tires have this marking).
205 - Tire width in millimeters.
55 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches.
89 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the
speed rating chart in this section
for additional information.Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
6.0JX16
6.0 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches.

5. Maximum permissible inflation
pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum per-
missible inflation pressure. Refer to
the Tire and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as
the factory installed tire.
7. Uniform Tire Quality Grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
Treadwear 200
Traction AA
Temperature A Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom-
mend that tires be replaced after
approximately six (6) years of normal
service. Heat caused by hot climates
or frequent high loading conditions
can accelerate the aging process.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

Maintenance
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. Grades B and A
represent higher levels of perform-
ance on the laboratory 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.
