Operating Safety; High-Voltage Electrical System - Mercedes-Benz B-Class Electric Drive Operator's Manual

should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
!
There is a risk of damage to the vehicle if:
the vehicle becomes stuck, e.g. on a high
R
curb or an unpaved road
you drive too fast over an obstacle, e.g. a
R
curb, speed bumps or a pothole in the road
a heavy object strikes the underbody or
R
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed
to.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
Danger of electric shock
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.

Operating safety

All of the vehicle's high-voltage electrical sys-
tem components are marked with yellow warn-
ing stickers which warn you about high voltages.
The cables of the vehicle's high-voltage electri-
cal system are orange.
When towing a vehicle after an accident, be sure
to observe the following sections:
Transporting the vehicle (
R
Towing the vehicle with the front axle raised
R
( page 253)
Y
Towing a vehicle with both axles on the
R
ground ( page 253)
Y
Read the important safety instructions on tow-
ing away ( page 251).
Y
The ignition must be switched off when carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the vehicle's

high-voltage electrical system

If the restraint systems are activated during an
accident, the vehicle's high-voltage electrical
system is automatically deactivated.
This is to ensure that you do not come into con-
tact with high voltage.
Automatic protection from switching
on of the vehicle's high-voltage electri-
cal system
The vehicle's high-voltage electrical system is
not activated when the vehicle is started if:
a serious electrical insulation malfunction is
R
detected in the vehicle's high-voltage electri-
cal system
an electrical connection in the vehicle's high-
R
voltage electrical system is disconnected
