Service products 365 Certain countries have diesel fuel with varying sulphur content. Diesel fuel with low sulphur content is sold in certain countries under the name "Euro diesel". Details about current country-specific fuel sulphur content can be obtained from the Mercedes-Benz Specification for Service Products according to Sheet No. 136.2. Fur- ther information can be obtained from a Mercedes-Benz Service Centre. the diesel fuel. This can cause damage to the injection system, for example. The vehicle may be equipped with a fuel pre- heating system. The fuel preheating system can warm up the fuel by approximately 8 †. This improves the flow characteristics of the fuel.
AdBlue ® Diesel fuels at low temperatures AdBlue ® notes G WARNING If you heat fuel system components, e.g. with a hot-air gun or naked flame, these compo- nents could be damaged. This can cause fuel to escape and ignite. Depending on the type of damage, fuel may also not escape until the engine is running. There is a risk of fire and explosion. Never heat fuel system components. Contact a qualified specialist workshop to rectify the malfunction. ! Only use AdBlue ® /DEF in accordance with DIN 70070/ISO 22241. Do not use any additives. If AdBlue ® /DEF comes into contact with painted or aluminium surfaces when filling the tank, rinse the affected area immedi- ately with plenty of water.
If the AdBlue ® tank still contains enough AdBlue ® , pressure compensation may occur when the tank lid is unscrewed. AdBlue ® may spill out. Therefore, open the AdBlue ® tank lid carefully. If AdBlue ® spills out, immediately wash the affected area with plenty of water. AdBlue ® is a non-flammable, non-toxic, col- ourless, odourless and water-soluble liquid. When opening the AdBlue ® tank, small amounts of ammonia vapours could escape. Ammonia vapours have a pungent smell and are particularly irritating to: In winter months, diesel fuel with an improved cold flow quality is available. In Europe, the EN 590 standard defines various climate- dependent temperature categories.
Malfunc- tions can be avoided by refuelling with diesel fuel that corresponds to the climatic specifi- cations outlined in EN 590. At unusually low outside temperatures, it is possible that the flow characteristics of the diesel fuel may be insufficient. Accordingly, diesel fuel from warmer areas may not be suitable for opera- tion in colder climatic conditions. Technical data R skin R mucous membranes i Further information on country-specific fuel properties and fuel types with low-tem- perature resistance can be obtained from oil companies, e.g. at filling stations.
R eyes The vapours may cause a burning sensation in the eyes, nose and throat as well as irritation of the throat and watering eyes. Avoid inhaling ammonia vapours. Only fill the AdBlue ® tank in well-ventilated areas. AdBlue ® should not come into contact with skin, eyes or clothing, and should not be swal- lowed. Keep AdBlue ® out of the reach of chil- dren.
