Emission control system
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 Informa
-
tion 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 func
-
tion of the emission control sys
-
tems, it is recommended that you
have your vehicle inspected and
maintained by an authorised Kia
dealer in accordance with the main
-
tenance schedule in this manual.
Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
䳜 To prevent the vehicle from mis
-
firing during dynamometer test
-
ing, turn the ESC off by pressing
the ESC switch.
䳜 After dynamometer testing is
completed, turn the ESC 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
Positive Crankcase Ventilation (PCV)
valve into the induction system.
2. Evaporative emission control
(including Onboard Refuelling
Vapour Recovery (ORVR)) system
The evaporative emission control
system is designed to prevent fuel
vapours from escaping into the
atmosphere. (The ORVR system is
designed to allow the vapours from
the fuel tank to be loaded into a
canister whilst refuelling at the gas
station, preventing the escape of
fuel vapours 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.
