GL 320 BLUETEC (164.825) V6-3.0L DSL Turbo (642.820) (2009)
Working with dirty operating fluids
One must strictly ensure that AdBlue is kept separate from other operating fluids, fuels and lubricants such as coolant, engine oil, transmission oil, fuel,
hydraulic fluid and brake fluid and not used in the same containers and collecting pans. The smallest amounts of AdBlue can damage thermostats or
temperature sensors. Operating fluids which contain traces of AdBlue must not be used again.
Working with dirty AdBlue
AdBlue must be checked as per the repair instructions before every fill. Individual components of the BlueTec system already react very sensitively with
even the smallest traces of contaminants in AdBlue. When handling AdBlue it is important, therefore, to always use clean containers and collecting pans
which are only reserved for this purpose. Dirty AdBlue must not be used again.
Protecting vehicle components when working with AdBlue
AdBlue leads to corrosion on electronic components and strong fouling on all other materials. It is therefore necessary to cover up all components in the
vicinity over the whole surface with plastic foil when working in circumstances where AdBlue could leak out.
Storage and packaging
Storage at temperatures between 0°C/32°F and 25°C/77°F should be secured in order to avoid crystallization occurring in AdBlue.
To avoid deterioration in quality due to contamination, AdBlue must only be handled in storage and filling systems intended exclusively for AdBlue.
Suitable container materials are alloyed steel, various plastics and plastic coatings in metal containers. One should not use unalloyed steel, aluminum,
copper, copper-containing alloys and zinc-dipped steel.
Disposal and degradability
Disposal of AdBlue:
When disposing of AdBlue one should observe the legal
requirements of the country in which the AdBlue is used.
Dirty packaging/materials:
Packaging which contain residues of AdBlue is to be handled like
the substance itself. Packaging should emptied as well as possible;
it can then be reused after appropriate cleaning with water.
