DANGER
Improper handling of the high-voltage system and
battery can result in burns, injuries or fatal electric
shock.
It must always be assumed that the high-voltage
▶
battery is charged and that the high-voltage sys-
tem is live. This also applies when the electric drive
is switched off and the ignition is switched off.
The components of the high-voltage system, e.g.
▶
the high-voltage cables and the high-voltage bat-
tery, neither catch on nor touch with the help of
objects.
Do not carry out any work on the high-voltage sys-
▶
tem or the high-voltage battery.
Work on the high-voltage system and the systems
▶
influenced by it may only be carried out by qualified
service technicians.
Do not open or repair the components of the high-
▶
voltage system.
Do not replace, remove or disconnect the orange
▶
high-voltage cables.
Do not open, replace, or remove the cover of the
▶
high-voltage battery.
Damage to the vehicle or the high-voltage battery
▶
can result in the escape of toxic and flammable
gases. Open the windows to ensure that any gases
are vented and exit the vehicle.
Avoid contact with liquids and gases coming from
▶
the high-voltage battery.
In the event of fire, leave the vehicle and stay at a
▶
safe distance. Inform rescuers about the fact that
it is a vehicle with a high-voltage
After an
accident.
CAUTION
Touching the floor of the vehicle or an accident may
damage the high-voltage battery.
Contact a specialist company immediately and en-
▶
sure the high-voltage battery is checked.
NOTICE
In the event of a vehicle with a flat high-voltage bat-
tery, there is a risk of irreversible damage to the
high-voltage battery during extended periods of use
A flat high-voltage battery must be recharged im-
▶
mediately!
NOTICE
If the vehicle is stationary for several months, the
high-voltage battery can go flat.
This can lead to the high-voltage battery being dam-
aged at high ambient temperatures and a low charge
state.
Always ensure there is a sufficient state of charge
▶
with the high-voltage battery!
If the battery is left standing for long periods in
very cold environments, the low internal tempera-
ture of the high-voltage battery can reduce the
range and limit the driving performance.

High Voltage System Overview
The high-voltage system in the vehicle consists of
the following main components:
High-voltage battery
▶
Power electronics
▶
Electric motor
▶
High-voltage air-conditioning compressor
▶
Charger for the high-voltage battery
▶
Charging socket
▶
Orange high-voltage cable and plug
▶
High-voltage heating system
▶
The high-voltage battery is located under the ve-
hicle floor and is not accessible to users.
Charging of high-voltage battery
What you should be mindful of
WARNING
Danger of life-threatening electric shock, fire hazard,
danger of damage to vehicle.
Follow the correct procedure for charging.
▶
Connect the charging cable to a power outlet that
▶
is protected from both moisture and liquids.
Only charge at correctly installed and undamaged
▶
sockets and at a faultless electrical installation.
Have the sockets and electrical installations
checked at regular intervals.
Never charge in potentially explosive areas. Com-
▶
ponents of the charging cable can cause sparks
and thus ignite explosive vapours.
Protect the charging plugs from moisture and liq-
▶
uids.
Do not carry out work on the vehicle while charg-
▶
ing.
Always remove the charging cable before starting
▶
up the vehicle. Fit the protective cap and close the
battery charging flap.
Never charge several vehicles at the same time at
▶
the mains sockets of a fuse circuit.
Observe the maximum charge capacity of the fuse
▶
circuit used. If the charging cable is plugged into a
socket of the same circuit together with other
consumers, the circuit may be overloaded and the
charging process may be interrupted.
WARNING
Never use damaged charging plugs or charging ca-
▶
bles.
