Auxiliary heating 103 G WARNING Parts of the vehicle, e.g. the exhaust system, may become very hot when the auxiliary heat- ing system is switched on. Flammable material, such as leaves, grass or twigs, may ignite if it comes into contact with: guarantee a sufficient supply of fresh air, open the roof hatch or a door on the side of the vehicle away from the wind. ! If the auxiliary heating has not been used for an extended period, exposure to heat and condensation can lead to deposits forming in the auxiliary heating fuel system. These deposits can cause the auxiliary heating to malfunction.
Have the auxiliary heating checked and repaired at a qualified specialist workshop before using it again. R hot parts of the exhaust system R the exhaust gas itself There is a risk of fire. Make sure, when the auxiliary heating system is switched on, that: R hot vehicle components do not come into contact with flammable material ! Turn on the auxiliary heating at least once a month for approximately ten minutes. Otherwise, the auxiliary heating could be damaged. Climate control R exhaust gases can emerge unobstructed from the exhaust pipe R exhaust gases do not come into contact with flammable material ! The auxiliary heating may only be oper- ated with conventional diesel fuel.
Operat- ing with 100% fatty acid methyl ester (FAME) fuel or diesel fuel with an admixture of more than 10% fatty acid methyl ester (FAME) fuel can lead to malfunctions and is therefore not permitted. G DANGER If you have preselected a switch-on time, the auxiliary heating system switches on auto- matically. R Toxic exhaust fumes may accumulate if there is insufficient ventilation, carbon monoxide in particular. This is the case in enclosed spaces, for example. There is a risk of fatal injuries. Mandatory switch-off !
When the auxiliary heating system is in heating mode and during its cooling off period, the power supply shall be discon- nected using the battery isolator switch only in the event of danger. If the power supply is interrupted in heating mode, the cooling off period can not be initiated and the auxiliary heating system may sustain damage. R There is a risk of fire and explosion if there are highly flammable materials or flamma- ble materials nearby! If you park the vehicle in these or similar con- ditions, always deactivate the preselected switch-on times.
G DANGER If the exhaust pipe is blocked or sufficient ventilation is not possible, toxic exhaust fumes may enter the vehicle, especially car- bon monoxide. This is the case, for example, if the vehicle gets stuck in snow. There is a risk of fatal injuries. If you have to leave the engine or the auxiliary heating running, keep the exhaust pipe and the area around the vehicle free of snow. To Z
