cables are orange in color.
You could be seriously or even fatally injured
if you:
R tamper with components or the high-
voltage cables of the hybrid system
R touch components or high-voltage cables
in the hybrid system of a vehicle which has
been involved in an accident
R touch damaged components of the hybrid

Important safety notes
G
WARNING
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your
vehicle may not be heard by other road users
in certain situations, for example when
parking or when your vehicle has not been
seen by other road users.
This requires you to adopt aparticularly
anticipatory driving style, as it is necessary to
allow for the possibility that other road users
may behave erratically. G
WARNING
Always have work on the vehicle carried out
by a qualified specialist workshop .In
particular, work relevant to safety, to safety-
related systems, to the hybrid system as well
as maintenance work must be carried out at
a qualified specialist workshop. The specialist
workshop must have the necessary specialist
skills and tools to carry out the work required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose.

safety, see the vehicle Operator's Manual. Modifications to the vehicle
G
WARNING
Work carried out incorrectly on the hybrid
system or modifications made to your vehicle
could cause the systems of your vehicle to
cease functioning properly. As a result, there
is a risk that you may lose control of your
vehicle and thus cause an accident.
Therefore, have all work on the hybrid system
and modifications to the vehicle, such as
installations or conversions, carried out at a
qualified specialist workshop.
i For further information about operating
safety, see the vehicle Operator's Manual. Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.
