Air conditioning system operation tips
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
To help reduce moisture inside of win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month if only for a few minutes to
ensure maximum system performance.
When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.

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) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized KIA dealer.
✽ ✽ NOTICE
• If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate is suddenly decreased, the system should be
checked at an authorized KIA dealer.

Maintenance

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
G050800AUN
Air cleaner filter
A Genuine KIA air cleaner filter is recom-
mended when the filter is replaced.
G050900AUN
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
G051000AUN
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized KIA dealer should perform
the operation.
G051100AUN
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
G051500AUN
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
G051600AUN
Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4
specification.

AIR CLEANER
G160100AUN-EC
Filter replacement
It must be replaced when necessary, and
should not be cleaned and reused. Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals.
G170100AUN-EC
Filter inspection
If the vehicle is operated in severely air-
polluted cities or on dusty rough roads for
a long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control air
filter, replace it performing the following
procedure, and be careful to avoid dam-
aging other components.
OMG075012
CAUTION
Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
Use a KIA genuine part. Use of non-genuine parts could damagethe air flow sensor.

EMISSION CONTROL SYSTEM
G270000AUN-EU
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized KIA dealer in accordance with the
maintenance schedule in this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
G270100AUN
1. Crankcase emission control system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
G270200AFD
2. Evaporative emission control
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
