Safety of the high-voltage system
Vehicle features and options
This chapter describes all standard, country-
specific and optional features offered with
the series. It also describes features and
functions that are not necessarily available
in your vehicle, e.g., due to the selected op-
tions or country versions. This also applies
to safety-related functions and systems.
When using these functions and systems,
the applicable laws and regulations must be
observed.
Working on the vehicle
General information
The manufacturer of your vehicle recom-
mends that no changes be made to the vehi-
cle, for instance installation of retrofitting
accessories, that will have an effect on the
vehicle’s high-voltage system.
Safety information
DANGER
Improperly performed work, in particular
maintenance and repair on the high-volt-
age system, can lead to electric shock.
There is a risk of injury, fire and danger to
life.
The manufacturer of your vehicle recom-
mends that the work on the vehicle, in par-
ticular maintenance and repair, be per-
formed by a dealer’s service center or
another qualified service center or repair
shop.
Contact with water
The high-voltage system is typically safe
even in the following example situations:
– Water in the floor area, for instance af-
ter a rainstorm when the window was
kept open.
– Vehicle is in water but only up to the al-
lowed height.
– Fluid escapes in the cargo area.
Monitoring of the high-volt-
age battery
Principle
The temperature in the high-voltage battery
is monitored.
An unusually high temperature in the high-
voltage battery is indicated.
Safety information
Warning
An unusually high temperature of the
high-voltage battery can cause a formation
of gas and smoke. There is an injury haz-
ard or danger to life. In case of noticeable
unusual odor or smoke formation, refer to
the notes for actions in the event of a mes-
sage.
