Driving tips 215 X Shift the transmission to neutral position N . Replacing the filter G WARNING Direct contact or inhalation of soot particles is hazardous to health. There is a risk of injury. Have the diesel particle filter replaced at a qualified specialist workshop. X Remove your foot from the accelerator. X Press button : for approximately three seconds. Manual regeneration only begins if: R the engine oil and exhaust temperatures are sufficiently high R AdBlue ® is not frozen R the system is functioning without prob- lems The Й indicator lamp lights up in the instrument cluster and the engine speed is increased. When regeneration is finished: Fuel consumption depends on:
Fuel consumption Driving mode R vehicle version R operating conditions R maintenance R the fuel type in use R the Й indicator lamp in the instru- ment cluster goes out R driving resistance R your driving style For these reasons, exact figures about any individual vehicle's fuel consumption cannot be provided. R the engine speed is reduced to idling speed Regeneration is automatically interrupted if you: i The on-board computer shows informa- tion on average fuel consumption in the trip data menu Я ( Y page 119). R move the multifunction lever into position D or R R release the parking brake R switch on the regeneration block The interruption reduces the engine speed to idling speed.
AdBlue ® consumption AdBlue ® consumption is between approx- imately 2 to 4 % of fuel consumption. i During regeneration, the engine noise may change. i If the on-board computer prompts you to carry out manual regeneration when the outside temperature is low, start regener- ation before parking the vehicle. If you park the vehicle without regenerat- ing, you can only begin manual regenera- tion after the engine warming-up phase. Start the manual regeneration after a thaw- ing time of up to 60 minutes if: Engine oil consumption After running-in the engine, oil consumption may reach 0.2 % of the vehicle's fuel con- sumption.
Increased distance covered and more ardu- ous operating conditions could result in vehi- cles exceeding this value. R AdBlue ® is frozen Limiting the speed R you have parked the vehicle without regenerating If the maximum speed of the vehicle is excee- ded, there is a risk that tractor/trailer com- Z
