It is essential that AdBlue® be kept separate from other
operating fluids, fuels and lubricants such as coolant,

Handling contaminated materials

It is essential that AdBlue® does not come into contact with
materials used in the interior of the vehicle. AdBlue®
exposed to air passes within just a few hours from a liquid
state into the crystalline state and can therefore damage
and destroy contaminated surfaces.

Textiles, e.g. the reversible mat in the luggage
compartment, which have been fouled with AdBlue®
should be alternately cleaned and then rinsed with water
several times.

It must be ensured that there are no further traces of
AdBlue® in the textiles.

CAS (Chemical Abstracts Service) no.: 57-13-6

Marking

AdBlue® dispensers are marked with the standard
designation ISO 22241 or with the trade designations
AdBlue® or Diesel Exhaust Fluid (DEF).

Transport

In vehicles with BlueTEC technology, AdBlue® is carried in
a tank,

engine oil, transmission oil, fuel, hydraulic fluid and brake
fluid and not used in the same containers and collecting
bowls. The smallest amounts of AdBlue® can damage
thermostats or temperature sensors.

Operating fluids which contain traces of AdBlue® must not
be used again.

Handling contaminated AdBlue®

AdBlue® must be checked as per the repair instructions
before every fill. Individual components of the exhaust
aftertreatment 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 bowls which are
only reserved for this purpose. Contaminated AdBlue®
must not be used again.

Handling contaminated tools

All tools coming into contact with AdBlue® must be
thoroughly cleaned with water immediately after use!

Only fully dried measuring instruments and filling tools
should be used so as not to dilute the AdBlue®
concentration.

Protecting 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 ensured in order to avoid crystallization occurring

Emissions Campaign 2020040008

Notes on use, material properties and handling of AdBlue®

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.

Service life and durability

AdBlue® breaks downs during storage into ammonium
hydroxide and carbon dioxide and then no longer fulfills the
requirements of standard ISO 22241.

If the recommended storage temperature of a maximum of
25°C/77°F is maintained, the AdBlue® will fulfill the
requirements of this standard for at least 18 months after
manufacture. If this recommended storage temperature is
exceeded then this period is reduced. Duration of storage
and the temperatures to be used are given as guideline
values at the end of the document. At temperatures below
-11°C/12 °F, the AdBlue® freezes and becomes solid.

On warming up again the frozen AdBlue® becomes liquid
again and can be reused without any loss of quality.

>35 / 95 - --

Not to be used are unalloyed steel, aluminum, copper,
copper-containing alloys and zinc-dipped steel.

The maximum permissible service life of AdBlue® can be
taken from the MB Specifications for Operating Fluids.

Disposal and degradability

Disposal of AdBlue®:

When disposing of AdBlue® the legal requirements of the
country in which the AdBlue® is used must be observed.

Contaminated packaging/materials:

Packaging which contains 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.

Information on preventing
damage to electronic
components due to electrostatic
discharge

opical note

Electrostatic charge

Every contact and every physical separation of materials or
every movement of solids, liquids or charged particle-
containing gases can generate electrostatic charge.
Plastics generally produce the highest electrostatic charge.

We come across electrostatic charge or discharge in lots of
everyday situations, e.g. with:

Combs
Walking on carpets or plastic floors

Putting on and taking off textiles with synthetic fiber
content

Disembarking from the vehicle

Contact between various electrostatically chargeable
packaging materials in shelves or in the transport
container

The following electronic components listed as an example
can be damaged by ESD:

Airbag components

Control units, in particular their bus connections
Controller Area Network (data bus/CAN bus) (CAN),
Local Interconnect Network (LIN) etc.

Sensors

Mechatronic component parts (actuators etc.)
Antenna amplifier

Receivers and displays (Radio, TV, GPS, telephone
etc.)

Modes of behavior and safety precautions

Electrostatic discharge of the technician (e.g. by briefly
touching the vehicle body).

Suitable clothing, e.g. made of cotton.
Wear ESD safety shoes with conductive soles.

Keep workplace clean and clear away unnecessary
objects such as conventional plastics.

Special antistatic seat cushion protectors should be
used when performing repair work inside a vehicle.

Leave replacement parts in the original packing for as
long as possible, do not tear open seals but cut them
open carefully

The ESD workplace must conform to the ESD
guidelines.

The resulting electrostatic discharge (Electrostatic
Discharge (ESD)) can be so strong that a small electric
shock is detected. Even the smallest discharges which
people cannot detect can cause lasting damage to
electronic components and control units.

Effects and consequences of ESD

Electronic components and control units are very sensitive
to ESD. The damage is often not immediately obvious, but
becomes apparent some time later. In order to avoid
failures and damage due to ESD in vehicle electronics,
various procedures and safety precautions must be taken
into account and followed.

Risk of damage arises during the transportation, handling,
testing, removal and installation of electronic components
during production and repair work.

+ The operation-specific documentation in the WIS must
be observed and the specified special tools and/or
workshop equipment must be used in each case.

+ Before unpacking, discharge ESD protective packaging
at the ESD workplace.

+ Avoid any contact with electrostatic chargeable
materials such as, e.g. polyethylene, PVC, styrofoam.

+ Use only original packaging or specially labeled and
defined packaging and transport materials.

+ Electronic components which have been removed must
be put down on an ESD workplace.

+ Electrical connectors on electronic component parts and
in the wiring harness should be touched by their
housing only. Do not touch pins or contacts!

+ Electronic components must be installed before they are
connected so that potential equalization with the body
can take place.

+ Shelves and worktables must stand directly on the floor,
there must not be any insulating materials between the
base of the shelves/feet and the floor. If the above
mentioned insulators cannot be removed, the shelves
and work tables must be grounded (e.g. low-resistance
electrical connection/line from metal shelf to a coolant
pipe).

* Do not put down conductive containers/crates when
insulated,

(e.g. on a wooden pallet), as otherwise potential
equalization will not take place.

+ Do not place control units and electronic components
removed from the vehicle on electrostatically

chargeable materials, such as PE, PVC, styrofoam. The

Training

It is strongly recommended that every company has an
ESD officer trained in accordance with DIN EN 61340-5-1.

The ESD officer can carry out staff training courses.

The aim of the training measures is to communicate the
main problems and effects of ESD to staff:

+ Discharge generation
+ Reasoning for safety precautions
+ Effects and consequences of ESD

+ ESD rules of conduct and safety precautions

electrostatic charge is transferred to the control unit or
electronic component. An ESD service kit or a
connected ESD table mat must be used.

Return of electronic components in warranty and
goodwill cases

When returning electronic components it is absolutely
essential to observe the procedure and safety precautions
listed. The original fault may be falsified or hidden by
electrostatic charge/discharge.

This can lead to distorted fault symptoms in the case of the
fault analysis of the component concerned.

Notes on carrying out repair work in the vehicle interior

Notes on carrying out repair
work in the vehicle interior

Cee)

In order to prevent soiling or damage, the following
information must be observed:

+ Before starting repairs in the vehicle interior, the
corresponding protective covers must be provided in the
repair area for the floor coverings, seats, steering
wheel, etc. to prevent them from becoming dirty.

+ Persons performing work in the vehicle interior should
ensure they have clean work clothes, clean shows and
clean hands.

When removing bulky or difficult to handle parts (e.g.
bench seat, roof lining, instrument panel etc.), always
work with aid of at least a second person.

Do not use dirty or unapproved tools. This prevents any,
e.g. scratching or crazing of interior parts etc.

Always place removed interior parts on a clean and soft
surface.

Further information:

+ Repair or replace damaged interior parts (particularly
mounts such as retaining clips, Velcro fasteners etc.).

+ When installing interior parts at the intended locations,
install insulation material and/or protective foils, or,
replace insulation material/protective foils as required in
order to dampen vibrations and noise.

+ Many equipment parts in the area of the vehicle interior
have been installed or made specifically to the

customer's request, and cannot be replaced easily if
damaged or soiled; for this reason, utmost care must be
ensured when carrying out operations in the vehicle
interior.

Remove any dirt present with cleaners approved by
Daimler and suitable for corresponding surfaces. When
doing so, where possible, the compatibility of the
cleaning agent should be tested at a concealed area of
the part to be cleaned.
