Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded petrol, otherwise the catalytic converter will be irreparably damaged.
Never allow the fuel tank to run completely dry, as the irregular supply of fuel can cause misfiring. This allows unburnt fuel to enter the exhaust system, which can cause overheating and damage to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel particulate filter
The diesel particulate filter can filter out almost all soot particles contained in the exhaust gas. In normal driving conditions the filter is self-cleaning. Should the self-cleaning function of the filter not be able to operate, e.g. when the vehicle is continuously used only for short trips, the filter becomes obstructed with soot.
Indicator lamp (for diesel particulate filter)
Applies to: vehicles with diesel particulate filter
Particulate filter: system fault. See owner s manual
The diesel particulate filter requires regeneration. You can assist the self-cleaning function of the filter by driving as follows:
Drive at a speed of at least 60 km/h for about 15 minutes with the selector lever in position S. Keep the engine speed at a minimum of 2000 rpm. As a result of the increase in temperature, the soot in the filter will be burned off. The indicator lamp will go out once the cleaning process has been completed successfully.
If the indicator lamp does not go out, drive to a qualified workshop without delay and have the fault rectified.
WARNING
The exhaust system is very hot when the vehicle is being driven and after the engine has been switched off.
- Never touch the tailpipes when they are hot – risk of burns!
- Because of the high temperatures which can occur in the emission control system, do not park the vehicle where the exhaust can come into contact with flammable materials under the car (e.g. on grass or at the forest edge) – risk of fire!
- Do not apply any underseal agents in the area around the exhaust system - risk of fire!
- (Applies to vehicles with diesel particulate filter: ) Always adapt your speed to the weather, road, (or off-road) and traffic conditions when regenerating the diesel particulate filter. The recommended driving speed must never lead to the driver disregarding the traffic regulations.
Note
Applies to: vehicles with diesel particulate filter
- As a result of the high temperatures which occur during the regeneration of the diesel particulate filter, the radiator fan may continue to run after the engine is switched off, even if the engine has not yet reached operating temperature.
- Noises, odours and increased engine speeds may be noticed during regeneration.
- To maximise the service life of the diesel particulate filter, always use suitable engine oil and the correct fuel.
