Checking and relling levels
The degassing hole of the 12-volt battery must
always be on side of the negative pole. The
degassing hole on the side of the positive pole
must always be sealed.
Only use maintenance-free 12-volt batteries
that comply with the TL82506 and VW75073
standards. These standards must be dated Oc-
tober 2014 or later.
The 12-volt battery must always be replaced
by a qualied technician, as the vehicle's elec-
tronic system must also be adjusted as part of
the replacement. In addition, the battery pa-
rameters relating to operational safety can only
be determined with the original battery. Only
a qualied technician has both access to the
right technology to make the adjustment and
the correct replacement batteries.
NOTICE
The use of batteries that do not meet CU-
PRA’s quality specications, or with a ca-
pacity lower than that tted as standard,
could, depending on the local legislation in
each country, lead to the loss of approval or
the corresponding administrative permits for
the vehicle. In addition, it may pose a serious
safety risk.
Disconnecting the 12-volt battery
If the 12-volt battery is to be disconnected
from the vehicle's electrical system, please
note the following:
●
Switch
o all electrical consumers.
●
Before disconnecting the battery, unlock the
vehicle, otherwise the alarm will be triggered.
●
First disconnect the negative cable and then
the positive cable ››› .
Connecting the 12-volt battery
●
Switch o all electrical consumers before re-
connecting the 12-volt battery.
●
First reconnect the positive cable and then
the negative one ›››
.
After connecting the 12-volt battery and
switching on the ignition, several control lamps
may light up. These lamps go out after a short
distance at a speed of approx. 15 to 20 km/h
(10 to 12 mph). If the warning lights do not go
out, visit a specialist workshop and have the
vehicle checked.
If the 12-volt battery has been disconnected
for a long period of time, it is likely that
the next service will not be correctly indi-
cated or calculated ›››page15 . In this
case it will be necessary to take into account
the maximum permitted maintenance intervals
›››page329.
Vehicles with a “Keyless Access” system
›››page94: If the ignition cannot be switched
on after connecting the 12-volt battery, lock
and unlock the vehicle from the outside. Then
try to switch on the ignition again. If the ignition
does not work, seek professional assistance.
Automatic disconnection of consumers
In the event of excessive demand on the
12-volt battery, the on-board network smart
management system automatically takes cer-
tain measures to prevent the battery from dis-
charging:
●
If necessary, the power of the most powerful
consumers is limited or, in an emergency, they
are switched o completely.
Factors causing the 12-volt battery to dis-
charge
●
Use of electric consumers while the drive
system is disconnected.
WARNING
Attaching the 12-volt battery incorrectly or
using unsuitable batteries may result in short
circuits, re and serious injury.
●
Use only maintenance-free 12 volt batter-
ies with an anti-spill system with the same
properties, specications and dimensions as
the factory-tted battery.
