Maintenance
Emission control system (if
equipped)
The emission control system of
your vehicle is covered by a written
limited warranty. Please see the
warranty information contained in
the Warranty & Maintenance book 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 func-
tion of the emission control sys-
tems, have your vehicle inspected
and maintained by a professional
workshop in accordance with the
maintenance schedule in this man-
ual. Kia recommends to visit an
authorised Kia dealer/service part-
ner.
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 sys-
tem
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 control
system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
absorbed in the canister are drawn
into the surge tank through the
purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
