Maintenance
EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system oý your
vehicle is covered by a written limited
warranty. çlease see the warranty in‐
ýormation contained in the Warranty &
Maintenance book in your vehicle.
Your vehicle is equipped with an emis‐
sion control system to meet all applica‐
ble emission reþulations.
There are three emission control sys‐
tems, as ýollows.

1. Crankcase emission control system

2. Evaporative emission control sys‐
tem

3. Exhaust emission control system

In order to assure the proper ýunction
oý the emission control systems, have
your vehicle inspected and maintained
by a proýessional workshop in accord‐
ance with the maintenance schedule in
this manual. Kia recommends to visit an
authorized Kia dealer/service partner.
Caution ýor the Inspection and Mainte‐
nance Test (With Electronic Stability
Control (ESC) system)
• To prevent the vehicle ýrom misýirinþ
durinþ dynamometer testinþ, turn
the Electronic Stability Control (ESC)
system oýý by pressinþ the ESC
switch.
8-114
• Aýter dynamometer testinþ is com‐
pleted, turn the ESC system back on
by pressinþ the ESC switch aþain.
1. Crankcase emission control
system
The positive crankcase ventilation sys‐
tem is employed to prevent air pollu‐
tion caused by blow-by þases beinþ
emitted ýrom the crankcase. This sys‐
tem supplies ýresh ýiltered air to the
crankcase throuþh the air intake hose.
Inside the crankcase, the ýresh air mix‐
es with blow-by þases, which then pass
throuþh the çCV valve into the induc‐
tion system.
2. Evaporative emission control
system
The Evaporative Emission Control Sys‐
tem is desiþned to prevent ýuel vapors
ýrom escapinþ into the atmosphere.
Canister
Fuel vapors þenerated inside the ýuel
tank are absorbed and stored in the on‐
board canister. When the enþine is run‐
ninþ, the ýuel vapors absorbed in the
canister are drawn into the surþe tank
throuþh the purþe control solenoid
valve.
Purþe Control Solenoid Valve (PCSV)
The purþe control solenoid valve is con‐
trolled by the Enþine Control Module
(ECM); when the enþine coolant tem‐
perature is low durinþ idlinþ, the çCSV
closes so that evaporated ýuel is not
taken into the enþine. Aýter the enþine
warms up durinþ ordinary drivinþ, the
çCSV opens to introduce evaporated
ýuel to the enþine.
3. Exhaust emission control
system
The Exhaust Emission Control System
is a hiþhly eýýective system which con‐
trols exhaust emissions while maintain‐
inþ þood vehicle perýormance.
Vehicle modiýications
This vehicle should not be modiýied.
Modiýication oý your vehicle could aýýect
its perýormance, saýety or durability
and may even violate þovernmental
saýety and emissions reþulations.
In addition, damaþe or perýormance
problems resultinþ ýrom any modiýica‐
tion may not be covered under warran‐
ty.
