Exhaust gas purification system
Safety instructions – Exhaust
gas purification system
Danger
•
Do not touch any parts such as engine block, cooling system and exhaust system during
operation and for some time after. There is a risk of burns! Allow the engine to cool down.
•
The diesel particle filter and the SCR catalytic converter get very hot. Risk of fire and burns!
•
Do not reach into the area of the exhaust outlet. Keep children and other persons away from this
area.
•
When operating the vehicle, make sure that no easily inflammable materials are in the direct
vicinity of the exhaust system, especially the exhaust pipe.
•
When parking the vehicle while the engine is running, make sure that no inflammable or
combustible materials (e.g. paper, dry grass, straw, wood, wooden building materials, oil, fuels,
etc.) are in the direct vicinity of the exhaust outlet.
•
Do not park the vehicle in high dry grass. Never use additional underbody sealant or anti-
corrosive agents for exhaust pipes, heat shields or the diesel particle filter. These could ignite
when the engine is hot.
Attention
•
If the diesel particulate filter in the multifunction display lights up red, the vehicle engine must be
switched off immediately. Serious engine damage can be caused if this is not complied with.
•
Use only commercially available AdBlue to refuel the vehicle. Otherwise, the exhaust system will
be damaged or reliable cleaning will no longer be guaranteed. Only use AdBlue as per ISO 22241
or DIN 70070.
•
Do not dilute AdBlue and to not add additives.
•
In the event of malfunctions and damages at the exhaust gas purification system resulting from
the application of AdBlue that does not meet the specifications and non-observance of this infor-
mation, no warranty claims will be acknowledged.
•
If exposed to intense heat above 50 °C (e.g. due to sunshine) over a longer period of time,
ammonia may be released resulting in a pungent smell. Do not inhale escaping vapours when
opening the tank. Ammonia vapours in this concentration are, however, not detrimental to health.
•
Wipe the surfaces of components which might come into contact with AdBlue, e.g. when topping
up, immediately with water.
•
When refuelling AdBlue, always observe the information on topping up volumes as the tank could
burst due to overfilling and low outside temperatures.
•
The vehicle is equipped with an AdBlue preheating system which ensures operation of the
exhaust gas purification system at temperatures below -11 °C. If the vehicle is used in regions
where outside temperatures are always below -10 °C, install special measures to ensure correct
AdBlue dosage and trouble-free engine operation.
•
When refuelling using a pump nozzle with automatic shutoff, there is no risk of overfilling as the
supply is stopped automatically when the max. permissible tank volume has been reached. When
refuelling from canisters, always observe the topping up volume and avoid overfilling.
Environmental danger
•
Ensure safe and environment-conserving disposal of operating and auxiliary materials. Take up
escaping or spilled operating materials in suitable containers and dispose of them in an environ-
mentally friendly manner.
