11. Once the wheel lug nuts have
been tightened, lower the vehicle
fully to the ground and continue to
tighten the lug nuts until they are
fully secured. Tighten the wheel
lug nuts firmly in a “X” pattern.
If you are unsure of the tightness
of the wheel lug nuts, have them
checked at the nearest service
station. The specified tightening
Improperly tight-
ened wheel lug nuts could cause
brake pedal vibration while brak-ing. To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.

CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheelremoval that the same nuts removed are reinstalled - or, ifreplaced, that nuts with metricthreads and the same chamfer configuration are used.Installation of a non-metricthread nut on a metric stud or vice-versa will not secure thewheel to the hub properly andwill damage the stud so that it must be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installing aftermarket lug nuts or wheels.If in doubt, consult anAuthorized Kia Dealer.
WARNING - Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to theloss of the wheel and a colli-sion.
WARNING
Check the inflation pressures as
soon as possible after installing
the spare tire. Adjust it to the
specified pressure, if necessary.
Refer to Section 8, Specifications.

OWNER MAINTENANCE
Owner maintenance schedule
The following lists are vehicle checks and inspections that should be per-
formed by the owner or an
Authorized Kia Dealer at the fre-quencies indicated to help ensure
safe, dependable operation of your
vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolant reservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, levelroad.
When stopping, listen and check for strange sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air conditioning system after use is
normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow out
under pressure. This could
cause serious injury.

Tire rotation
To equalize tread wear, it is recom- mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire
also if you can see fabric or cord.
After rotation, be sure to bring thefront and rear tire pressures to spec-
ification and check lug nut tightness.
Refer to Section 8, Specifications.Disc brake pads and rear brake
shoes should be inspected for wearwhenever tires are rotated.
✽✽ NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right toleft.

WARNING
Do not use the compact spare tire for tire rotation
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-tics that could result in death,
severe injury, or property
damage.

Tire replacement
If the tire is worn evenly, a tread wear indicator will appear as a solid band
across the tread. This shows there isless 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.Compact spare tire replace- ment (if equipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new Kia and should be mounted onthe same compact spare tire wheel.The compact spare tire is notdesigned to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel alignment and tire balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
✽✽
NOTICE
Improper wheel weights can dam-
age your vehicle's aluminum wheels.
Use only approved wheel weights.

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 widthand offset.WARNING
When replacing tires, never mix radial, bias-belted, and
bias-type tires. All four tires
should be of the same size,
design and construction. Use
only the tire sizes listed on the
Tire Label found below the
door striker on the driver’s
side. Make sure that all tires
and wheels are the same size
and have the same load-carry-
ing capacity. Use only tire andwheel combinations recom-
mended on the Tire Label or
by an Authorized Kia Dealer.
Failure to follow these precau-
tions can adversely affect the
safety and handling of your
vehicle.
(Continued)(Continued)
The use of any other tire sizeor type may seriously affect
ride, handling, ground clear-
ance, tire clearance, andspeedometer calibration.
Driving on worn-out tires is very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-tion.
It is best to replace all four tires at the same time. If that is
not possible, or necessary,
then replace the two front or
two rear tires as a pair.Replacing just one tire can
seriously affect your vehicle’shandling.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer calibration, head-
light aim and bumper height.

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 designationmean.
Example tire size designation: 195/60 R15 87H
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)195 - Tire width in millimeters.
60 - Aspect ratio. The tire’s section
height as a percentage of its width.
R - Tire construction code (Radial).
15 - Rim diameter in inches.
87 - 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: 6.0 J x 15
6.0 - Rim width in inches. J - Rim contour designation.
15 - Rim diameter in inches. Tire speed ratings
The chart below shows many of the
different speed ratings currently
being used for passenger car. The
speed rating symbol is part of the tire
size designation on the sidewall of
the tire. This symbol corresponds to
that tire's designed maximum safe
operating speed.

Uniform tire quality grading
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe 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 as well on the government
course as a tire graded 100. The relative performance of tiresdepends upon the actual conditions
of their use. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on Kia vehicles
may vary with respect to grade.
Traction - A, B & C
The traction grades, from highest to
lowest, are A, B and C. The gradesrepresent the tires ability to stop on
wet pavement as measured undercontrolled conditions on specified
government test surfaces of asphalt
and concrete. A tire marked C may
have poor traction performance.
Temperature -A, B & C
The temperature grades are A (the
highest), B and C. The grades repre-
sent the tire’s resistance to the gener-ation of heat and its ability to dissipateheat when tested under controlledconditions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tires to
degenerate and reduce tires life, and
excessive temperature can lead to
sudden tires failure. Grades A and B
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by the
law.

Checking a tire life
Tire strength and performance
decline with age. Any tires that are
over 6 year old, including the spare
(determined by the tire manufacturedate), should be replaced regardless
of mileage. You can find the tire man-
ufacture date on the tire sidewall(either on the inside or outside of the
wheel). The date is a Department Of
Transportation (DOT) number con-
sisting of letters and numbers. You
can determine the tire manufacture
date by the last four numbers of the
DOT code.DOT : XXXX XXXX OOOO
The first letters/numbers of the DOT
indicate the manufacturing plant, tire
size and tread pattern, last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 0806 represents
that the tire was produced in the 8th
week of 2006.
WARNING
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates orfrequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning can result in sudden
tire failure, which could lead to a
loss of control and an accident
involving serious injury ordeath.
WARNING - Tire
temperature
The temperature grade for this
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
tires failure. This can cause loss
of vehicle control and serious
injury or death.
