Charging, replacing, disconnect-
ing and connecting the 12-volt ve-
hicle battery
Please refer to , and on page
312 and and at the start of the
chapter on page 325.
If you suspect that the 12-volt vehicle bat-
tery is damaged or faulty, go to a suitably
qualified
workshop and have the 12-volt ve-
hicle battery checked.
Charging the 12-volt vehicle battery
The 12-volt vehicle battery should always
be charged by a correspondingly
qualified
workshop, as the technology used in facto-
ry-fitted
12-volt vehicle batteries requires
voltage-limited charging

Replacing the 12-volt vehicle battery
The 12-volt vehicle battery has been devel-
oped to suit the conditions of its location
and has special safety features. If a 12-volt
vehicle battery has to be replaced, the re-
placement part must be installed by
a workshop
qualified
to do this. For compo-
nent information on size and the required
maintenance, capacity and safety features,
please contact a correspondingly
qualified
workshop, which must have the necessary
technical documentation and equipment.
The ventilation opening of the 12-volt vehi-
cle battery must always be on the negative
terminal side. The ventilation opening on
the positive terminal side must always be
sealed.
Only maintenance-free 12-volt vehicle bat-
teries compliant with the standards
TL 825 06 and VW 7 50 73 should be used.
These standards must be dated October
2014 or later.
The 12-volt vehicle battery must always be
replaced by a workshop
qualified
to do this,
as the vehicle electronics must be adapted
as part of the replacement process. In addi-
tion, the battery parameters for functional
safety were determined only with the origi-
nal equipment battery. Only correspond-
ingly
qualified
workshops have the technol-
ogy required to carry out this adjustment
and also the correct replacement batteries.
The use of unsuitable batteries can render
the type approval invalid.
Disconnecting the 12-volt vehicle bat-
tery
Please note the following if the vehicle bat-
tery has to be disconnected from the elec-
trical system in the vehicle:
1. Switch
off
all electrical consumers and
the ignition.
2. Unlock the vehicle before disconnecting
the battery in order to avoid triggering
the
anti-theft
alarm (if
fitted)
.
3. First disconnect the negative cable and
then the positive cable

Connecting the 12-volt vehicle battery
1. Switch
off
all electrical consumers and
the ignition before reconnecting the ve-
hicle battery.
2. First connect the positive cable and
then the negative cable
→
.
Various indicator lamps may light up
after
the 12-volt vehicle battery has been con-
nected and the ignition is switched on.
They will go out if you drive a short distance
at a speed of 15 km/h to 20 km/h (10 –
12 mph). If the indicator lamps continue to
light up, have the vehicle checked by a suit-
ably
qualified
workshop.
If the 12-volt vehicle battery was discon-
nected for an extended period, the system
may not able to calculate or correctly dis-
play the time when the next service is due
→
page 20. Observe the maximum permis-
sible service intervals.
Automatic switch-off for electrical con-
sumers
The vehicle electrical system cannot al-
ways prevent the 12-volt vehicle battery
from discharging.
— For example, when the ignition is switch-
ed on for an extended period with the en-
gine
off,
or when the side or parking lights
are on when the vehicle is parked for an
extended period.
To prevent the 12-volt vehicle battery from
discharging, the intelligent onboard supply
management system automatically imple-
