Operating safety

General notes

Always read the chapter "Operating safety" as
well as the operator's manual. You could oth-
erwise fail to recognize dangers, e. g. due to
high-voltage.

Danger of electric shock

The components of the drive system are indi-
cated by yellow warning labels to make you
aware of high voltage.
High‑voltage cables are orange‑colored.
G DANGER
The vehicle's high voltage electrical system is
under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
Only specially trained technicians may carry
out work on the vehicle. If orange electric
cables or their connectors are damaged, have
them replaced immediately at a qualified spe-

WARNING
cialist workshop. We recommend that you
use a Mercedes-Benz Center for this purpose.
Automatic switch‑off of the high-volt-
age system
The high-voltage system will be automatically
switched off, in the event of an accident in
which the restraint systems are triggered.
This helps to avoid that you get in contact with
high-voltage.
Please refer to section "Operating safety" in
the operator's manual for more information
on the this subject.

Performing work on the vehicle

G WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
i
Read the information on qualified special-
ist workshops in the operator's manual.
Work carried out incorrectly on the high-
voltage system or modifications made to
your vehicle could cause the systems of
your vehicle to cease functioning properly.
Always have maintenance work on drive sys-
tem and high-voltage system electronics and
components performed by a qualified spe-
cialist. We recommend that you use an
authorized Mercedes-Benz Center for this
purpose.
Please make sure you read the technical documentation, such as
the Operator's Manual and workshop information, before carrying
out any maintenance work.
