Maintenance
Remove the valve cap from the tire
valve stem. Press the tire gauge 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 gauge. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture. Inspect your tires frequently for
proper inflation as well as wear and
damage. Always use a tire pres-
sure gauge.
Tires with too much or too little pressure wear unevenly causing
poor handling, loss of vehicle con-
trol, and sudden tire failure leading
to accidents, injuries, and even
death. The recommended cold tire
pressure for your vehicle can be
found in this manual and on the tire
label located on the driver's side
center pillar.
Remember to check the pressure of your spare tire. Kia recommends
that you check the spare every
time you check the pressure of the
other tires on your vehicle.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 “Tire and wheels” in chapter
8.

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 3,000 km(1,900 miles).
CAUTION
It is not easy to recognize the tire damage with your owneyes. But if there is the slight-est hint of tire damage, eventhough you cannot see the tiredamage with your own eyes,have the tire checked orreplaced because the tiredamage may cause air leak-age from the tire.
If the tire is damaged by driv- ing on a rough road, off road,pothole, manhole, or curbstone, it will not be covered bythe warranty.
You can find out the tire infor- mation on the tire sidewall.
