Engine exhaust gases
Warning: Exhaust gases contain carbon monoxide (CO), a colorless, odorless gas. Inhaling carbon monoxide can cause unconsciousness or even death. Exhaust gases can enter the vehicle's interior in the following situations:
- The vehicle with the engine idling is in a poorly ventilated area (parking lots, garages, tunnels, deep snow that can block air circulation under the vehicle or clog exhaust pipes).
- There is an unusual smell or sound coming from the exhaust system.
- The exhaust system has a leak due to corrosion or damage.
- The vehicle's exhaust system has been modified, damaged, or improperly repaired.
Warning: The vehicle body contains holes or openings from damage or aftermarket modifications that have not been completely sealed.
If unusual gases are detected or there is a suspicion that exhaust gases are entering the vehicle:
- Drive your car only with the windows fully lowered.
- Contact a service station immediately to have the vehicle repaired. Never stop the vehicle with the engine running in closed spaces, garages or rooms that are not well ventilated.
Diesel particulate filter
The diesel particulate filter system removes soot particles from the engine exhaust gases. The system has a self-cleaning function (filter regeneration), which is performed automatically while driving. The filter is cleaned by burning off soot particles at high temperatures. This process is performed automatically under certain driving conditions and can take more than 15 minutes. Odor and smoke are a normal consequence of the self-cleaning process.
In certain driving conditions, such as short distance driving, the system may not clear automatically.
If the control indicator (DPF lamp) L lights up or flashes, it is necessary to activate the cleaning process of the diesel particulate filter by continuing safe driving until the DPF lamp on the instrument cluster goes out. If possible, driving at a steady pace is more favorable for the cleaning process.
Warning: Make sure to follow the precautions listed below because the exhaust gas temperature becomes very high during the DPF regeneration process.
- Remember that contact with hot exhaust system components may cause burns and fire. Do not park the vehicle over paper, leaves, dry grass or other flammable materials.
- Turn off the ignition immediately after entering the car into the garage.
- Do not pass near the outlet of hot exhaust gases, including the muffler outlet pipe.
Catalytic converter
The catalytic converter reduces the amount of harmful substances in the exhaust gases.
Caution: Using low quality or low octane fuel may 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 push-start or tow the engine.
In case of misfiring, rough running, loss of engine efficiency or other unusual problems, contact a workshop as soon as possible to have them fixed. In extreme cases, driving at low speed and low engine speeds for a short period of time is permissible.
Caution: Do not touch the catalytic converter while the engine is running - it is very hot and can cause burns. Wait at least two hours after stopping the engine to allow the catalytic converter to cool.
