Maintenance
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is rec-
ommended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance (if equipped)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
✽ ✽
NOTICE
Automatic transmission fluid color
is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace the
element more often than the usual
recommended intervals. (Refer to
“Maintenance under severe usage
conditions” in this chapter.)
CAUTION - Air filter
maintenance
Do not drive with the air clean-
er removed; this will result in
excessive engine wear.
When removing the air cleaner
filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
Use a Kia genuine part. Use of
a non-genuine part could
damage the air flow sensor.

Maintenance
CLIMATE CONTROL AIR FILTER
Filter inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. 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 fol-
lowing procedure, and be careful to
avoid damaging other components.
1. Open the glove box and remove
the stoppers on both sides.2. With the glove box open, pull the
support strap (1).

Maintenance
EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty & Consumer Information
manual in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
There are three emission control
systems, as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized Kia dealer in accor-
dance with the maintenance sched-
ule in this manual.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
After dynamometer testing is
completed, turn the ESC system
back on by pressing the ESC
switch again.1. Crankcase emission control
system
The positive crankcase ventilation
system 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.
2. Evaporative emission con-
trol (including ORVR:
Onboard Refueling Vapor
Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
(The ORVR system is designed to
allow the vapors from the fuel tank to
be loaded into a canister while refu-
eling at the gas station, preventing
the escape of fuel vapors into the
atmosphere.)
