DEF (BlueTEC vehicles only) Important notes on use To function properly, BlueTEC exhaust gas aftertreatment must be operated with the reducing agent DEF. Adding DEF is one of the tasks performed during maintenance. Under normal operating conditions, a tank of DEF lasts until the next service due date. When the supply of DEF is almost used up, the Check Additive See Operator's Check Additive See Operator's Manual Manual message is shown in the multifunction display. When the DEF supply drops to a minimum, the Remaining Starts: 16
Remaining Starts: 16 message is shown in the multifunction display. If the Remaining Starts: 16
appears in the multifunction display, you can start the engine another 16 times. If DEF is not refilled, you will subsequently be unable to start the engine. Refill the DEF tank with approximately 1 gal (3.8 l) DEF. Have the DEF tank refilled at a qualified specialist workshop. Use the special DEF refill bottle when adding DEF between maintenance intervals. Contact an authorized Mercedes-Benz Center with any questions or, if necessary, contact Roadside Assistance (Y page 24). If the outside temperature is below 12 ‡ (Ò11 †) it may be difficult to top up. If DEF is frozen and there is an active warning indicator, it may not be possible to add DEF. Park the vehicle in a warmer place, e.g. in a garage, until DEF has become fluid again. It will then be possible to add DEF again. Alternatively, have the DEF tank refilled at a qualified specialist workshop. Further information about BlueTEC exhaust gas aftertreatment and DEF is available at any authorized Mercedes-Benz Center.Important safety notes on the refilling procedure DEF is a water-soluble fluid for the exhaust gas aftertreatment of diesel engines. It is: Rnot poisonous Rcolorless and odorless Rnot flammable When you open the DEF container, small amounts of ammonia vapor may be released. Ammonia vapors have a pungent odor and are particularly irritating to the skin, to mucous membranes and to the eyes. You may experience a burning sensation in your eyes, nose and throat. Coughing and watering of the eyes are possible. Do not inhale ammonia vapors. Fill the DEF tank only in well-ventilated areas. DEF must not come into contact with your skin, eyes or clothing and must not be swallowed. Keep DEF away from children. If you or other persons come into contact with DEF, observe the following: RRinse DEF from your skin immediately with
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical assistance without delay.
RIf DEF has been swallowed, rinse your mouth out immediately. Drink plenty of water. Seek medical assistance without delay.
RChange out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with DEF, and do not dilute DEF with water. This may destroy the BlueTEC exhaust gas aftertreatment system.
! Rinse surfaces that have come into
contact with DEF immediately with water or remove DEF using a damp cloth and cold water. If the DEF has already crystallized, use a sponge and cold water to clean it. DEF
residues crystallize after time and contaminate the affected surfaces.
! DEF is not a fuel additive and must not be added to the fuel tank. If DEF is added to the fuel tank, this can lead to engine damage.
! Only screw on the DEF refill bottle hand-
tight. It could otherwise be damaged.
