3. Exhaust emission control system
The Exhaust Emission Control System is a highly effective system which controls exhaust emissions whilst maintaining good vehicle performance.
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 vehicle, 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.
WARNINGExhaust
Engine exhaust gases contain carbon monoxide (CO). Though colourless and odourless, it is dangerous and could be lethal if inhaled. Follow the instructions on this page to avoid CO poisoning.
-
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.
-
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 catalytic converters (if equipped)

Fire
-
A hot exhaust system can ignite flammable items under your vehicle. Do not park the vehicle over or near flammable objects, such as grass, vegetation, paper, leaves, etc.
-
The exhaust system and catalytic system are very hot whilst the engine is running or immediately after the engine is turned off. Keep away from the exhaust system 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 corrosion control. It may present a fire risk under certain conditions.
Your vehicle is equipped with a catalytic converter emission control device.
Therefore, the following precautions must be observed:
-
Make sure to refuel your vehicle according to the "Fuel requirements" suggested on page 1-2.
-
Do not operate the vehicle when there are signs of engine malfunction, 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 control system. All inspections and adjustments must be made by a professional workshop. Kia recommends to visit an authorised Kia dealer/service centre.
-
Avoid driving with an extremely low fuel level. Running out of fuel could cause the engine to misfire, damaging the catalytic converter.
Failure to observe these precautions could result in damage to the catalytic converter and to your vehicle.
Additionally, such actions could void your warranties.
Petrol Particulate Filter (PPF) (if equipped)
The Petrol Particulate Filter (PPF) is the system that removes the soot from the exhaust gas. Unlike a disposable air filter, the PPF system automatically burns (oxidizes) and removes the accumulated soot whilst driving.
However, repeated short-distance driving or long-distance driving at a low speed can stop the accumulated soot from automatically
being removed by the PPF system. If the accumulated soot reaches a certain amount, the PPF warning light () will appear. To re-operate the PPF system, the vehicle should be driven for more than 30 minutes at a speed of 80 km/h (50
mph) and faster. Ensure the following conditions are met: safe road conditions, transmission 3 or above, and engine speed
of 1,500-4,000 rpm. Driving at 80 km/h (50 mph) or faster for recommended hours will get the PPF system back to work and stop
the PPF warning light.
If the PPF warning light stays on or the warning message “Check exhaust system” pops up even after driving at recommended speed and for recommended hours, visit a professional workshop and check the PPF system. Kia recommends to visit an authorised Kia dealer/service partner. Constant driving with the PPF warning light on can damage the PPF system and undermine fuel economy.
