7Element cleaningThis element may be air cleaned or
replaced, depending on its condition.
Unless it is very dirty, merely shake it to
remove foreign particles. Each time this
filter is inspected, wipe the inside of the
air cleaner housing and cover with a
damp cloth. If the vehicle is operated in
extremely dusty or sandy areas, clean or
replace this element more often than at
the usual recommended intervals.
✽ ✽
NOTICEDo not drive with the air cleaner ele-
ment removed; this will result in exces-
sive engine wear.

Maintenance
CLIMATE CONTROL AIR FILTER (IF EQUIPPED)The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) are position is selected. If this
happens, have the climate control air fil-
ter replaced by an Authorized Kia Dealer.The climate control air filter should be
replaced every 15,000 km (10,000
miles). If the vehicle is operated in the
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you try to replace
the air filter by owner maintenance,
replace it performing the following proce-
dure, and in this case, be careful to avoid
damaging other components.

7WIPER BLADES Wiper blade maintenance Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.
Contamination of either the windshield or
the wiper blades with foreign matter can
reduce the effectiveness of the wind-
shield wipers. Common sources of con-
tamination are insects, tree sap, and hot
wax treatments used by some commer-
cial car washes. If the blades are not wip-
ing properly, clean both the window and
the blades with a good cleaner or mild
detergent, and rinse thoroughly with
clean water.✽ ✽
NOTICETo prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
Windshield wiper blade replace-
ment When the wipers no longer clean ade-
quately, the blades may be worn or
cracked, and require replacement.✽ ✽NOTICETo prevent damage to the wiper arms or
other components, do not attempt to
move the wipers manually. ✽ ✽NOTICEThe use of a non-specified wiper blade
could result in wiper malfunction and
failure.
1. Raise the wiper arm and turn the wiper
blade assembly to expose the plastic
locking clip.✽ ✽NOTICEDo not allow the wiper arm to fall
against the windshield, since it may chip
or crack the windshield.

BATTERY
WARNING
- Battery dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and all other flames or sparks
away from the battery.
Hydrogen, which is a highly combustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.

For best battery service : Keep the battery securely mounted.
 Keep the top of the battery clean and
dry.
 Keep the terminals and connections clean, tight, and coated with petroleum
jelly or terminal grease.
 Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
 If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
Battery recharging Your vehicle has a maintenance-free,
calcium-based battery.
 If the battery becomes discharged in ashort time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
 If the battery gradually discharges because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.Items to be reset after the battery hasbeen discharged or the battery hasbeen disconnected. Clock (See Chapter 3)
 Climate control system (See Chapter 4)
 Audio (See Chapter 3)
 Sunroof (See Chapter 3)
(Continued)
 When lifting a plastic-cased bat- tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
 Never attempt to charge the bat- tery when the battery cables are
connected.
 The electrical ignition system works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.

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.
