Safety of the high-voltage system
Vehicle equipment
This chapter describes equipment, systems and
functions which are offered or will be offered on
a model-specific basis, even if they are not inclu‐
ded in the vehicle in question.
For further information:
Vehicle equipment, see page 7.
Working on the vehicle
General
Changes and work on the vehicle, for example
the retrofitting of accessories, must only be car‐
ried out by a Service Partner of the manufacturer
or another qualified Service Partner or a special‐
ist workshop that operates to BMW specifica‐
tions with suitably trained personnel.
Safety note
WARNING
An electric shock can occur if the work is not
carried out correctly, in particular maintenance
and repair of the high-voltage system. There is
a danger of injury, fire or danger to life. Only
have work on the vehicle, particularly mainte‐
nance, repair and modifications, carried out by a
Service Partner of the manufacturer or another
qualified Service Partner or a specialist work‐
shop.
Contact with water
The high-voltage system is generally safe also in
the following example situations:
▷ When there is water in the footwell, for exam‐
ple after a rain shower with the window open.
▷ The vehicle is in water up to the allowed
height.
▷ If liquid spills in the luggage compartment.
Monitoring the high-voltage
battery
Principle
The temperature in the high-voltage battery is
monitored.
An unusually high temperature in the high-volt‐
age battery is indicated.
Safety note
WARNING
An unusually high temperature of the high-volt‐
age battery can cause a formation of gas and
smoke. There is a danger of injury or danger to
life. In case of noticeable unusual odour or
smoke formation, refer to the notes for actions
in the event of a message.
High temperature message
While the vehicle is moving
A Check Control message is shown.
During and shortly after the charging
process
Depending on the national-market version: the
vehicle sounds the horn and, if applicable, the
vehicle lights are flashing.
