Exhaust emission control system
The Exhaust Emission Control System is a highly effective system which controls exhaust emissions while maintaining good vehicle performance.
When the engine starts or fails to start, excessive attempts to restart the engine may cause damage to the emission system.
-
Carbon monoxide can be present with other exhaust fumes. If you smell exhaust fumes of any kind in your vehicle, drive with all the windows fully open. Have your vehicle checked and repaired immediately.
Engine exhaust gases contain carbon monoxide (CO). Though colorless and odorless, 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.
The exhaust system and catalytic system are very hot while the engine is running or immediately after the engine is turned off. To avoid serious injury or death:
-
Do not park, idle, or drive the vehicle over or near flammable objects, such as grass, vegetation, paper, leaves, etc. A hot exhaust system may ignite flammable items under your vehicle.
-
Keep away from the exhaust system and catalytic converter or you may get burned.
Also, do not remove the heat sink around the exhaust system, do not seal the bottom of the vehicle, and 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.
To prevent damage to the catalytic converter and to your vehicle, take the following precautions:
-
Use only UNLEADED FUEL for gasoline engines.
-
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 engine off and descending steep grades in gear with the engine 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. We recommend that all inspections and adjustments must be made by an authorized HYUNDAI dealer.
-
Avoid driving with an extremely low fuel level.
Running out of fuel could cause the engine to misfire, damaging the catalytic converter.
Failure to follow these precautions may void your vehicle warranty.
Gasoline Particulate Filter (GPF) system removes the soot in the exhaust gas.
The GPF system automatically burns (or oxidizes) the accumulated soot in accordance with driving situations, unlike a disposable air filter.
In other words, the accumulated soot is automatically purged out by the engine control system and by the high exhaust gas temperature at normal/high driving speeds.
However, when the vehicle is continually driven at repeated short distances or driven at low speed for a long time, the accumulated soot may not be automatically removed because of low exhaust gas temperature. In this case, the accumulated soot may reach a certain amount regardless of the soot oxidization process, then the GPF lamp (
) illuminates.
The Gasoline Particulate Filter (GPF) lamp stops illuminating, when the driving speed exceeds 80 km/h (50 mph) with engine RPM 1,500-4,000 and the gear in the 3rd position or above for approximately 30 minutes.
When the GPF lamp starts to blink or the warning message “Check exhaust system” pops up even though the vehicle was driven as mentioned above, we recommend that you have the GPF system checked by an authorized HYUNDAI dealer.
With GPF lamp blinking for an extended period of time, it may damage the GPF system and lower the fuel economy.
We recommend you to use only the regulated gasoline fuels, when your vehicle is equipped with the GPF system.
When you use other gasoline fuels which contain unspecified additives, they may damage the GPF system and cause exhaust emission problems.
