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.)

Maintenance

Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present
with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

7117
Maintenance
Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
When the vehicle is stopped in an
open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped
vehicle for any extended time with
the engine running.
When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to
the emission control system.Operating precautions for catalyt-
ic converters (if equipped)
WARNING- Catalytic
converter
Keep away from the catalytic
converter and exhaust system
while the vehicle is running or
immediately thereafter. The
exhaust and catalytic systems
are very hot and may burn you.
WARNING- Fire
Do not park, idle or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.

Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for
gasoline engines.
Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the
engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.
Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
