Engine exhaust
Warning: Exhaust contains carbon monoxide (CO), colorless and odorless. Breathing carbon monoxide can cause unconsciousness and even death. Exhaust fumes can enter the vehicle interior in the following situations:
- The car with the engine idling is located in places with poor ventilation (parking lots, garages, tunnels, deep snow that can block the air circulation under the bottom or block the exhaust pipes).
- An unusual smell or sound comes from the exhaust system.
- The exhaust system is leaking due to corrosion or damage.
- The vehicle's exhaust system has been altered, damaged or improperly repaired.
Warning: There are holes or openings in the body of the vehicle from damage or aftermarket modifications that have not been fully sealed.
If unusual gases are detected or there is a suspicion that exhaust gases are getting into the car:
- Drive only with the windows fully down.
- Immediately contact a workshop to have the vehicle repaired. Never park your vehicle with the engine running in confined spaces, garages, or areas that are not well ventilated.
Diesel particulate filter
The particulate filter system in a diesel engine removes soot particles from the engine's exhaust gases. The system has a self-cleaning function (filter regeneration), which is automatically performed while driving. The filter is cleaned by burning soot particles at high temperature. This process is automatically performed under certain driving conditions and may take more than 15 minutes. Smell and smoke are normal consequences of the self-cleaning process.
In certain driving modes, such as when driving short distances, the system cannot be automatically cleaned.
If the control indicator (DPF lamp) L is on or flashing, the diesel particulate filter cleaning process must be activated by continuing safe driving until the DPF lamp in the instrument cluster goes out. If possible, a uniform movement is more favorable for the cleaning process.
Warning: Be sure to observe the precautions listed below, as the exhaust gas temperature becomes very high during the regeneration of the particulate filter.
- Remember that contact with hot parts of the exhaust system can cause burns and fire. Do not park your vehicle over paper, leaves, dry grass, or other flammable materials.
- Turn off the ignition immediately after the car enters the garage.
- Do not walk near hot exhaust gases, including the muffler outlet pipe.
Catalytic converter
The catalytic converter reduces the amount of harmful substances in the exhaust gases.
Caution: Use of poor quality or low octane fuel can damage the engine, catalytic converter or electronic components.
Unburned gasoline can overheat and damage the catalytic converter. Therefore, avoid excessively long engine starts, do not allow moisture to enter the fuel tank, and do not jog or tow start the engine.
In the event of misfiring, engine roughness, reduced engine efficiency, or other unusual problems, contact a workshop as soon as possible to have them repaired. If absolutely necessary, driving at low speed and low engine speeds is permissible for a short period of time.
Caution: Do not touch the catalytic converter while the engine is running - it is very hot and could cause burns. To allow the catalytic converter to cool down, wait at least two hours after stopping the engine.
