EMISSION CONTROL SYSTEM  
G270000AHM-EU  
G270100AUN  
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.  
The emission control system of your  
vehicle is covered by a written limited  
warranty. Please see the warranty infor-  
mation contained in the Warranty &  
Maintenance booklet in your vehicle.  
Your vehicle is equipped with an emis-  
sion control system to meet all applicable  
emission regulations.  
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.  
• After dynamometer testing is com-  
pleted, turn the ESC system back on  
by pressing the ESC switch again.  
There are three emission control sys-  
tems, as follows.  
(1) Crankcase emission control system  
(2) Evaporative emission control system  
(3) Exhaust emission control system  
G270200AUN  
2. Evaporative emission control  
(including ORVR: Onboard  
Refueling Vapor Recovery)  
system  
The Evaporative Emission Control  
System is designed to prevent fuel  
vapors from escaping into the atmos-  
phere.  
In order to assure the proper function of  
the emission control systems, it is rec-  
ommended that you have your vehicle  
inspected and maintained by an author-  
ized Kia dealer in accordance with the  
maintenance schedule in this manual.  
(The ORVR system is designed to allow  
the vapors from the fuel tank to be  
loaded into a canister while refueling at  
the gas station, preventing the escape of  
fuel vapors into the atmosphere.)

3. Exhaust emission control  
system  
The Exhaust Emission Control System is  
a highly effective system which controls  
exhaust emissions while maintaining  
good vehicle performance.  
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 solenoid valve.  
• Carbon monoxide can be present with  
other exhaust fumes. Therefore, if you  
smell exhaust fumes of any kind inside  
your vehicle, have it inspected and  
repaired immediately. If you ever sus-  
pect exhaust fumes are coming into  
your vehicle, drive it only with all the  
windows fully open. Have your vehicle  
checked and repaired immediately.

Vehicle modifications  
Purge Control Solenoid Valve (PCSV)  
This vehicle should not be modified.  
Modification of your vehicle could affect  
its performance, safety or durability and  
may even violate governmental safety  
and emissions regulations.  
In addition, damage or performance  
problems resulting from any modification  
may not be covered under warranty.  
• If you use unauthorized electronic  
devices, it may cause the vehicle to  
operate abnormally, wire damage, bat-  
tery discharge or fire. For your safety,  
do not use unauthorized electronic  
devices.  
The purge control solenoid valve is con-  
trolled by the Engine Control Module  
(ECM); when the engine coolant temper-  
ature is low during idling, the PCSV clos-  
es so that evaporated 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.  
WARNING - Exhaust  
Engine exhaust gases contain car-  
bon monoxide (CO). Though color-  
less and odorless, it is dangerous  
and could be lethal if inhaled.  
Follow the instructions on this  
page to avoid CO poisoning.

Maintenance  
G270303AAM  
• Do not operate the engine in confined  
or closed areas (such as garages) any  
more than what is necessary to move  
the vehicle in or out of the area.  
Your vehicle is equipped with a catalytic  
converter emission control device.  
Therefore, the following precautions  
must be observed:  
Operating precautions for catalytic  
converters (if equipped)  
• 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 vehi-  
cle 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.  
• Use only UNLEADED FUEL for gaso-  
line engines.  
• Do not operate the vehicle when there  
are signs of engine malfunction, such  
as misfire or a noticeable loss of per-  
formance.  
• 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 control sys-  
tem. All inspections and adjustments  
must be made by an authorized Kia  
dealer.  
• Avoid driving with a extremely low fuel  
level. Running out of fuel could cause  
the engine to misfire, damaging the  
catalytic converter.  
WARNING - Fire  
• A hot exhaust system can ignite  
flammable items under your vehi-  
cle. Do not park, idle or drive the  
vehicle over or near flammable  
objects, such as grass, vegeta-  
tion, paper, leaves, etc.  
• The exhaust system and catalytic  
system are very hot while the  
engine is running or immediately  
after the engine is turned off.  
Keep away from the exhaust sys-  
tem and catalytic, you may get  
burned.  
Also, do not remove the heat sink  
around the exhaust system, do  
not seal the bottom of the vehicle  
or do not coat the vehicle for cor-  
rosion control. It may present a  
fire risk under certain conditions.  
Failure to observe these precautions  
could result in damage to the catalytic  
converter and to your vehicle.  
Additionally, such actions could void your  
warranties.
