Cars with petrol engines
All Hyundai vehicles are equipped with a monobloc three-way exhaust gas converter, which reduces the content of carbon monoxide, hydrocarbons and nitrogen oxides in exhaust gases. When the exhaust gases pass through the converter, it heats up to a very high temperature. Therefore, the presence of a large amount of unburned fuel in the exhaust gases can cause the converter to overheat and create a dangerous situation. This can be avoided by observing the following rules:
Warning:
- Use only unleaded gasoline.
- Check engine performance. Overheating of the converter can be caused by a malfunction of the electrical equipment, the ignition system or the multipoint fuel injection system.
- If the engine stalls, knocks, or is difficult to start, take the vehicle to a Hyundai dealer as soon as possible for troubleshooting.
- Do not drive with a minimum amount of fuel in the tank. When the fuel is completely depleted, misfires of the mixture in the cylinders and damage to the converter occur.
- Do not let the engine idle for more than 10 minutes.
- Do not start the engine by pushing or towing the vehicle. This will overload the converter.
- To avoid burns, do not touch the hot catalytic converter or other parts of the exhaust system. Before touching the catalytic converter and other parts of the exhaust system, stop the engine and wait at least an hour.
- Remember that your best assistant is a Hyundai dealer.
- Do not stop the vehicle where there may be flammable materials underneath (dry grass, paper, fallen leaves or rags), which may ignite if touched with a hot catalyst and cause a fire.
