2020 VOLKSWAGEN ID.4 battery

This will also occur to a certain extent when
the v
ehicle is rolling to stop when in overrun
mode or travelling downhill.
The higher the charge level of the high-volt-
age battery, the lower the recuperation and
thus also the engine braking effect. No brake
energy recuperation occurs and therefore no
engine braking effect is available once the
high-voltage battery is fully charged

Position engaged and ECO assistance deac-
tiv
ated: no brake energy recuperation.
Position engaged and ECO assistance acti-
v

ated: automatic brake energy recuperation.
The energy recovery level is selected auto-
matically depending on the navigation data
and traffic situation.
Position engaged: high brake energy recu-
peration
The v

ehicle also performs recuperation when
the brake pedal is pressed.
Eco assistance
The ECO assistance function helps the driver
to use the engine braking effect of the vehi-
cle efficiently. It selects the energy recovery
level depending on the navigation data and
traffic situation.
The ECO assistance function can be switched
on and off in the vehicle settings in the Info-
tainment system.
Driving down hills
When driving down hills, you should drive in
position B if possible.
Never allow the vehicle to roll down moun-
tains or hills in the neutral position N. WARNING
The higher the charge level of the high-
v
oltage battery, the lower the engine brak-
ing effect, to the point where no engine
braking effect may be generated at all. This
puts more strain on the vehicle brake.
x Never fully charge the high-voltage bat-
tery at high elevations, e.g. at the top of
a pass, in order to facilitate a braking ef-
fect by means of recuperation when de-
scending.
x Reduce your speed before driving down
a long, steep gradient.
x When driving down a long, steep gradi-
ent, slow the vehicle using the vehicle
brake. Troubleshooting
Deactivation of the drive is imminent
The charge level of the high-voltage battery
is too low.

ehicle
operation.
The indicator lamp lights up red.
A text message is shown on the ID. Cockpit

WARNING
Improper use of the sockets and electrical
accessories can cause fires and se vere inju-
ries.
x Never leave children unsupervised in the
vehicle. Sockets and the devices connec-
ted to them can be used when the igni-
tion is switched on.
x If the electrical device gets too hot,
switch off the device immediately and
disconnect it from the socket. NOTICE
x In order to pre
vent damage to the electri-
cal system, never connect equipment that
supplies electric power, such as solar pan-
els or battery chargers for charging the
12-volt battery, to the 12-volt socket.
x Use only electrical devices that have been
approved in accordance with current
guidelines concerning electromagnetic
compatibility.
x In order to avoid damage due to voltage
fluctuations, always switch off any electri-
cal devices before switching the ignition
on or off and before activating the vehi-
cle

x
Damage to the v ehicle or to the high-
voltage battery could lead to a leak of
toxic gases or fluids, either immediately
or at a later time. These emitted gases
could also potentially cause a fire. Do
not inhale these gases.
x Never touch the fluids that leak from the
high-voltage battery.
x In the event of a fire, move away from
the hazard area and call the fire service.
x Always inform any attending fire and
emergency services that the vehicle is
fitted with a high-voltage battery. WARNING
Unqualified work on the high-voltage sys-
tem and on high-
voltage components can
lead to malfunctions, accidents and inju-
ries.
x Any work on the high-voltage system
must be carried out only by authorised
qualified workshops with corresponding
approval for this work. NOTICE
After an accident, or after the underside of
the v
ehicle has struck an obstacle, the high-
voltage battery must be checked by appropri-
ately qualified and trained experts. Warning signs for the high-
v

oltage system Please refer to , and at the start
of the chapter on page 273.
Where can warning signs be located?
The f

ollowing components may be marked
with the illustrated warning signs

Fig. 141
Warning sign on high- voltage battery.1
High voltages can cause serious injuries
or death. Ne

ver touch the battery termi-
nals with your fingers, tools, jewellery or
any metal objects. 2
The high-voltage battery contains dan-
gerous liquid and solid substances. Seri-
ous chemical burns and blindness can be
caused if it outgasses. Suitable eye pro-
tection and protectiv

e clothing should
always be worn when performing work
on the high-voltage battery to prevent the battery fluid coming in contact with
skin and eyes. If skin or eyes come into
contact with battery fluid, rinse the af-
fected areas with clean flowing water
for at least 15 minutes and seek a doctor
immediately. 3
The high-voltage battery can burn. The
high-
voltage battery must never be ex-
posed to fire, sparks or naked flames. Al-
ways handle the high-voltage battery
with care to avoid damage and fluid
leaks. 4
Always keep children away from the
high-

voltage battery. 5

Handling the high-voltage
battery
Care instructions
V
olkswagen recommends observing the fol-
lowing care instructions:

Upper battery charge limit
F
ull charging of the high-voltage battery is
not normally necessary in daily vehicle use.
The upper battery charge limit limits the
maximum charge level.

WARNING
Driving when the charge level of the high-
v oltage battery is too low can lead to the
vehicle breaking down when in traffic, and
can lead to accidents and serious injuries. The high-voltage battery can only be
charged at charging stations that meet
the requirements of the corresponding coun-
try and at least the f

ollowing standards:
