High-voltage system and high-voltage battery
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 system is live. This also ap-
plies 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 battery, neither catch on
nor touch with the help of objects.
Do not carry out any work on the high-voltage system 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 sys-
▶
tem.
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 dis-
▶
tance. Inform rescuers about the fact that it is a vehicle with a
high-voltage
battery.» page 31, After an
CAUTION
Touching the floor of the vehicle or an accident may damage the
high-voltage battery.
Contact a specialist company immediately and ensure the
▶
high-voltage battery is checked.
NOTICE
In the event of a vehicle with a flat high-voltage battery, 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 immediately!
▶
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 damaged 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 en-
vironments, the low internal temperature of the high-voltage
battery can reduce the range and limit the driving performance.
