High-voltage on-board electrical system
Danger of electric shock
⚠ DANGER
When working on high-voltage component parts, you
could receive an electric shock.
There is danger to life and limb!
In order to avoid risks, please observe the following:
• Do not tamper with high-voltage component parts
or the orange cables of the high-voltage on-board
electrical system.
• Do not touch high-voltage component parts or
orange cables of the high-voltage on-board electri-
cal system in vehicles involved in accidents.
• Do not touch damaged component parts or
any damaged orange cables of the high-voltage
on-board electrical system.
• Do not remove the covers marked with yellow
warning adhesive labels on the component parts of
the high-voltage on-board electrical system.
• Do not insert conductive parts into the charging
cable connector or the charging cable socket.
• For safety reasons, only use charging cables that
have been approved by Mercedes-Benz for use in
this vehicle. Observe the additional specifications
in your vehicle's Operator's Manual.
ⓘ
See the Operator's Manual of your vehicle for fur-
ther information and specifications.
All component parts of the high-voltage on-board elec-
trical system are marked with yellow warning adhesive
labels alerting you to the hazards due to high voltage.

All of the electric cables of the high-voltage on-board
electrical system in the vehicle are marked in the
orange signal color with cable coverings or additional
protective coverings.
High-voltage lines in the engine compartment
⑴ NOTE
Constructional modifications to high-voltage compo-
nents, high-voltage lines, and equipotential bonding
lines and their surroundings are not permissible.
Before carrying out general operations, such as replac-
ing bulbs or checking the coolant level, observe the
following:
• The ignition must be switched off.
• The charging cable for charging the high-voltage
battery must not be connected.
ⓘ
If such general work is carried out on a vehicle
with an electric drive, the country-specific specifi-
cations regarding statutory protective equipment
and the accident prevention regulations must be
observed, e.g. the latest audit standard of DGUV
Information 209-093 "Training for work on vehicles
with high-voltage on-board electrical systems" as
amended for Germany or the SAE J2344 "Guide-
lines for Electric Vehicle Safety".
For additional training please review the SAE
PD291808 "High Voltage Vehicle Safety Systems".
