Risk of explosion from
explosive gas. Risk of
poisoning and caustic burns
from swallowing battery
electrolyte. Risk of injury
through burns to skin and eyes
from battery acid or when
handling damaged lead-acid
batteries
No fires, sparks, open flames or
smoking. Wear acid-resistant
gloves, clothing and glasses.
Only pour battery acid into
suitable and appropriately
marked containers.
aDanger
Potential risks
Risk of explosion
When charging lead batteries with battery electrolyte
containing sulfuric acid, a highly explosive oxyhydrogen
gas mixture is created that ignites by means of fire, sparks,
open flames and smoking.
Risk of injury
The battery electrolyte contains diluted sulfuric acid that
causes caustic burns to the skin, eyes and mucous
membranes in the event of contact. Bonded electrolyte is
just as caustic as liquid electrolyte. Battery electrolyte mist
causes caustic burns to the eyes. If inhaled, this can result
in caustic burns to the mucous membranes and respiratory
paths. In the event of a short circuit from the battery
positive to ground, battery terminals and conductive objects
causing short circuit, e.g. tool or jewelry (watch band or
ring), become hot in seconds and red hot/liquid metal
sprays are released.
Risk of burn injuries
In the event of a short circuit from the battery positive to
ground, battery terminals and conductive objects causing
short circuit, e.g. tool or jewelry (watch band or ring),
become hot in seconds and cause burns.
Risk of poisoning
If battery electrolyte is swallowed, this can result in
symptoms of poisoning such as headache, dizziness,
stomach ache, respiratory paralysis, unconsciousness,
vomiting, caustic burns and cramps. Absorption of lead in
the body through contact with leaded components (battery
terminals, lead plates in damaged batteries) damages the
blood, nerves and kidneys; lead compounds are also toxic
for reproduction.

Safety precautions/instructions
• Wear acid-resistant gloves and clothing and safety
glasses with side guards.
• Only charge lead batteries in well ventilated rooms with
appropriate voltage and appropriate current with
approved chargers, taking into account the instructions
of the battery and battery charger manufacturers.
• No fire, sparks, open flames and smoking.
• Switch on the battery charger only after connecting to
the terminals; switch off the battery charger before
disconnecting from the terminals.
• Do not place any conductive objects on the battery and
do not wear any conductive jewelry (risk of short circuit).
• Always disconnect the negative terminal first; always
connect the positive terminal first (risk of short circuit
caused by tool).
• Strict caution is required when handling damaged
batteries (removing from vehicle damaged in accident)
because of the sharp edges on the fractured housing
and escaped electrolyte.
• Keep batteries and battery electrolyte away from
unauthorized persons (especially children).
• Only fill liquid battery electrolyte into suitable and
appropriately marked containers.
• Only store, transport and install batteries with liquid
battery electrolyte horizontally, otherwise battery
electrolyte can escape from the degassing holes.
• Ensure that at least one degassing hole at the battery is
not sealed, as otherwise overpressure builds that leads
to bursting of the battery.
• Ensure proper connection of the degassing line to the
degassing hole.
• Ensure the degassing line does not have any kinks and
is not blocked at any point.
• Observe the instructions for use for the respective lead
batteries and the operator’s manual of the vehicle.
• The battery housing may become brittle over time,
therefore do not expose the battery to direct sunlight.
• Discharged batteries may freeze and are thereby
damaged, therefore always store batteries at a location
protected against frost.

gloves, clothing and glasses.
aWarning
Potential risks
Risk of poisoning
Swallowing battery gel can cause symptoms of poisoning
such as headaches, dizziness, stomach aches, respiratory
paralysis, unconsciousness, vomiting, caustic burns and
cramps.
The absorption of lead in the body can cause damage to
blood, nerves and kidneys; in addition, lead compounds are
considered to represent a reproductive hazard.
Risk of injury
The bonded electrolyte set free is just as caustic as a
liquid electrolyte that can cause heavy caustic burns to skin
and eyes. Strict caution is required when handling
damaged lead-gel batteries (e.g. removing from vehicle
damaged in accident) because of the sharp edges on the
fractured housing and direct contact with the lead plates.
Safety precautions and rules of conduct
• No fires, sparks, open flames or smoking.

Notes on avoiding damage
through contamination and
foreign objects
Topical note
Information on affected component parts
With each maintenance and repair work to the engine as
well as to the ancillary assemblies and detachable parts
comes the danger of property damage caused by
contamination and foreign bodies.
Particularly at risk are:
• Exhaust gas turbocharger
• Hot film mass air flow sensor
• Compressor
• Emission control system
• All components involved in gas exchange
Notes on removal/installation
Openings through which soiling or foreign objects are
introduced into the engine, its ancillaries or detachable
parts, must be sealed immediately.
For this purpose, suitable, clean covers and plugs or clean,
lint-free rags are to be used.
p
Do not forget to remove all covers, plugs or rags when
assembling or when finalizing the work.
This avoids any damage and complaints about engine
running characteristics.
g
Before assembling or finalization work all components
are to be checked for soiling, left-over foreign objects and
any fluids, and if any are found they are to be removed.
Information on cleaning
For cleaning, use only clean tools and clean, lint-free rags.
Residues of cleaning agents and removed contaminants
must be cleared from the engine, ancillary assemblies and
detachable parts.
p
Do not use compressed air for removing any soiling.
Otherwise, components (e.g. the hot-wire element of the
hot film mass air flow sensor) could be damaged or
contamination could enter the engine, ancillary assemblies
and detachable parts without being noticed.

Notes on use, material
properties and handling of
AdBlue®
Topical note
Tasks of AdBlue®
AdBlue® serves to convert nitrogen oxides into water vapor
and nitrogen.
Chemical characterization and composition of
AdBlue®
The urea content is 32.5%. AdBlue® consists of urea
dissolved in demineralized water. AdBlue® is not an
additive.
Chemical formula: H2N-CO-NH2
Molecular weight (urea): 60.06 g/mol
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.

Physical and chemical properties of AdBlue®
State: Liquid
Color: Colorless, clear, light-yellow
Odor: Slight ammonia odor
pH value: 10 (aqueous solution, 10 %)
Crystallization temperature: –11 °C / 12 °F
Boiling point: 103 °C / 217 °F
Auto-ignition temperature: Not spontaneously inflammable
Density: approx. 1.09 g/cm3 at 20 °C / 68 °F
Viscosity (dynamic): approx. 1.4 mPa*s at 25 °C / 77 °F
Handling contaminated operating fluids
It is essential that AdBlue® be 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
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 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.
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
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.
Not to be used are unalloyed steel, aluminum, copper,
copper-containing alloys and zinc-dipped steel.

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.
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

Information on preventing
damage to electronic
components due to electrostatic
discharge
Topical note
Electrostatic charge
Every contact and every physical separation of materials or
every movement of solids, liquids or charged particlecontaining
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 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 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 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.

a Emissions Campaign 2020040008

• Do not place control units and electronic components
removed from the vehicle on electrostatically
chargeable materials, such as PE, PVC, styrofoam. The
electrostatic charge is transferred to the control unit or
electronic component. An ESD service kit or a
connected ESD table mat must be used.

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
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
Topical note
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.
