Children should always be kept away
from electrolyte and the 12-volt vehicle
battery.
·
Always wear eye protection and protec-
tive gloves.
·
Electrolyte is very aggressive. It can burn
the skin and can cause blindness. When
working with the 12-volt vehicle battery,
ensure that your hands, arms and face in
particular are protected from acid spill-
age.
·
Do not smoke during the work, and nev-
er work near naked flames or sparks.
·
When handling cables and electrical
equipment, avoid generating sparks and
electrostatic charge.
·
Never short circuit the battery terminals.
·
Never use a damaged 12-volt vehicle
battery. It can explode. Damaged 12-
volt vehicle batteries must be replaced
as soon as possible.
·
Never use a frozen 12-volt vehicle bat-
tery. Discharged 12-volt vehicle batter-
ies can already freeze at temperatures of
around 0°C (+32°F). Frozen 12-volt vehi-
cle batteries must be replaced immedi-
ately.
NOTICE
Do not expose the 12-volt vehicle battery to
direct daylight for an extended time.
·
The ultraviolet radiation can damage the
battery housing.
NOTICE
Protect the 12-volt vehicle battery against
frost if the vehicle is left standing for exten-
ded periods.
·
The 12-volt battery can freeze and be de-
stroyed as a result.
When you activate the vehicle’s drive
system after the 12-volt battery has
been totally discharged, replaced or after
a successful jump start, you may find that
system settings (time, date, personal conven-
ience settings and programming) have been
changed or deleted. Check and correct the
settings as necessary once the 12-volt vehi-
cle battery has been sufficiently charged.
Checking the electrolyte level
of the 12-volt vehicle battery
Please refer to , and on page 309
and and at the start of the chapter on
The 12-volt vehicle battery is located under
the bonnet.
The electrolyte level of the 12-volt vehicle
battery cannot be checked because the bat-
tery window is hidden by the main fuse box
of the vehicle.
Always have the electrolyte level of the 12-
volt vehicle battery checked by a qualified
workshop.
Charging, replacing, discon-
necting and connecting the
12-volt vehicle battery
Please refer to , and on page 309
and and at the start of the chapter on
If you suspect that the 12-volt vehicle battery
is damaged or faulty, go to a qualified work-
shop and have the 12-volt vehicle battery
checked.
Charging the 12-volt vehicle battery
The 12-volt vehicle battery should be charg-
ed by a qualified workshop, as the technology
used in factory-fitted 12-volt vehicle batter-
ies requires voltage-limited charging → .
Volkswagen recommends using a Volkswagen
dealership for this purpose.
