6TIRES PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
➀
Low Tire Pressure Indicator
➁
TPMS Malfunction Indicator
Each tire, including the spare, should
be checked monthly when cold and
inflated to the inflation pressure rec-
ommended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehi-
cle has tires of a different size than
the size indicated on the vehicle
placard or tire inflation pressure
label, you should determine the
proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a
Tire Pressure Monitoring System
(TPMS) that illuminates a low tire
pressure indicator when one or more
of your tires is significantly under-
inflated. Accordingly, when the low
tire pressure indicator illuminates,
you should stop and check your tires
as soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire caus-
es the tire to overheat and can lead
to tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
indicator.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is a separate indi-
cator, which displays the symbol
"TPMS" when illuminated. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intend-
ed. TPMS malfunctions may occur for
a variety of reasons, including the
installation of replacement or alterna-
tive tires or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction indicator after replacing
one or more tires or wheels on your
vehicle to ensure that the replace-
ment or alternate tires and wheels
allow the TPMS to continue to func-
tion properly.

In case of an emergency
Low tire pressure
indicator
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated. Immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible.
Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the compact
spare tire. Because the compact
spare tire is not equipped with a tire
pressure sensor, the TPMS malfunc-
tion indicator may go on and the Low
Tire Pressure indicator may go off
after restarting and about 20 minutes
of continuous driving.
TPMS (Tire pressure
monitoring system)
malfunctionThe TPMS malfunction indicator
comes on and stays on when there is
a problem with the Tire Pressure
Monitoring System. If Front Left sen-
sor fails, the TPMS malfunction indica-
tor comes on, but if Front Right, Rear
Left, or Rear Right tire is under-inflat-
ed, the low tire pressure indicator may
come on with the TPMS malfunction
indicator.
Have the system checked by an
authorized Kia dealer as soon as pos-
sible to determine the cause of the
problem.
WARNING
- Low pressuredamage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.
TPMS
CAUTION
In winter or cold weather, the low tire pressure indicator maybe illuminated if the tire pres-sure was adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

✽
NOTICEThe TPMS malfunction indicator
may be illuminated if the vehicle is
moving around electric power sup-
ply cable or radio transmitter such
as police stations, government and
public offices, broadcasting stations,
military installations, airports, or
transmitting tower, etc. which can
interfere with normal operation of
the Tire Monitoring System
(TPMS).
Changing a tire with TPMSIf you have a flat tire, the Low Tire
Pressure indicator will come on.
Have the flat tire repaired by an
authorized Kia dealer as soon as
possible or replace the flat tire with
the compact spare tire.✽ ✽NOTICENEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have
to replace the tire pressure sensor. Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended that you always have
your tires serviced by an authorized
Kia dealer as soon as possible. After you replace the low pressure
tire with the compact spare tire, the
TPMS malfunction indicator may illu-
minate after restarting and about 20
minutes of continuous driving
because the compact spare tire does
not have a sensor.
Once the low pressure tire is re-inflat-
ed to the recommended pressure
and installed on the vehicle, the
TPMS malfunction indicator and the
low tire pressure indicator will be
extinguished. If the low pressure and
TPMS malfunction indicators are not
extinguished after about 20 minutes
of continuous driving, please visit an
authorized Kia dealer.
You may not be able to identify a low
tire by simply looking at it. Always use
a good quality tire pressure gauge to
measure the tire's inflation pressure.
Please note that a tire that is hot
(from being driven) will have a higher
pressure measurement than a tire
that is cold (from sitting stationary for
at least 3 hours and driven less than
1.6 km (1 mile) during that 3 hour
period). Allow the tire to cool before
measuring the inflation pressure.

In case of an emergency
The compact spare should be inflat-
ed to 420 kPa (60 psi).✽ ✽NOTICECheck the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
 Under no circumstances should
you exceed 80 km/h (50 mph); a
higher speed could damage the
tire.
 Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
 Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
 Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
 Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately
25 mm (1 inch), which could result
in damage to the vehicle.  Do not take the vehicle through an
automatic car wash with a compact
spare.
 Do not use tire chains on this tire. Because of the smaller size, a tire
chain will not fit properly. This could
damage the vehicle and result in
loss of the chain.
 This tire should not be installed on the front axle if the vehicle must be
driven in snow or on ice.
 Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
 The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
CAUTION
- Compact
spare
This spare tire should be usedonly for VERY short distances.Compact spares should NEVERbe used for long drives orextended distances.

627
In case of an emergency
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 threadson the wheel studs and nuts.Make certain during wheelremoval that the same nutsremoved are reinstalled - or, ifreplaced, that nuts with metricthreads and the same chamferconfiguration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket 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 the
loss of the wheel and a collision
resulting in serious injuries.
WARNING -
Inadequate
spare tire pressure
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 performed by
the owner or an authorized Kia dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties 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 reser-voir.
 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 steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
 Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
 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 oper- ation 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 condition-
ing system during or after use is nor-
mal).
At least monthly: Check coolant level in the coolantrecovery reservoir.
 Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
 Check the inflation pressures of all tires including the spare.At least twice a year (i.e., every Spring and Fall) : Check radiator, heater and air condi- tioning hoses for leaks or damage.
 Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
 Check headlight alignment.
 Check muffler, exhaust pipes, shields and clamps.
 Check the lap/shoulder belts for wear and function.
 Check for worn tires and loose wheel lug nuts.
WARNING
- Radiationcoolant
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 burns or
other serious injury.

7TIRES AND WHEELS
Tire care For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.Recommended cold tire infla-
tion pressures All tire pressures (including the
spare) should be checked every day
when the tires are cold. “Cold Tires”
means the vehicle has not been driv-
en for at least three hours or driven
less than 1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING -
Tire underin-
flation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for protracted periods at high
speeds.

Maintenance
✽
✽NOTICE• Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
Authorized Kia Dealer.
• Overinflation produces a harsh ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards. ✽ ✽ NOTICE• Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
• Be sure to reinstall the tire infla- tion valve caps. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leak-
age. If a valve cap is missing,
install a new one as soon as possi-
ble.
Checking tire inflation pres-
sureCheck your tires once a month or
more.
Also, check the tire pressure of the
spare tire.How to checkUse a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
WARNING
- Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and lead
to sudden tire failure. This could
result in loss of vehicle control
and potential injury.
WARNING -
Tire pressure
Always observe the following:
 Check tire pressure when the tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km (one
mile) since startup.)
 Check the pressure of your spare tire each time you check
the pressure of other tires.
 Never overload your vehicle. Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
 Worn, old tires can cause acci- dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.

Maintenance26
7Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.
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 if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to Section 8, Specifications.
Disc brake pads should be inspected
for wear whenever tires are rotated.Rotate radial tires that have an
asymmetric tread pattern only
from front to rear and not from
right to left.

 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.
