Checking and topping up fluids
It will not be possible to restart the vehicle once
you have switched it off. The performance of cer-
tain vehicle functions may be limited and the ve-
hicle’s handling may be impaired. Drive to a
qualified workshop without delay.
the electrical equipment is powered back or
switched off. Certain convenience features, such
as interior lighting or electric seat adjustment,
may not be available. These functions will be re-
stored when you activate the drive system.
Electrical system: fault. Please contact
Even though some systems are deactivated auto-
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicle is left standing for long periods, this
can result in total 12-volt battery discharge. If
the vehicle battery is allowed to discharge com-
pletely, an internal chemical reaction damages
the battery irreparably. To avoid this, the battery
should be recharged at least once a month
ðpage 247. Please seek advice from a qualified
workshop.

Switch off any electrical equipment which is not
required (some equipment may be switched off
automatically). The performance of certain vehi-
cle functions may be limited and the vehicle’s
handling may be impaired. Drive to a qualified
workshop without delay.
Electrical system: low battery charge. Bat-
tery will be charged while driving
– If this message disappears after a while, the ve-
hicle battery will have been sufficiently charged
while driving.
Winter conditions
Cold weather is very hard on the 12-volt vehicle
battery. For this reason, you should have the bat-
tery checked by a qualified workshop before the
start of winter.
– If the message does not disappear again, drive
to a qualified workshop and have the fault rec-
tified.
Replacing the battery
WARNING
The following description applies to the 12-volt
vehicle battery. Any work on the battery must al-
ways be carried out by a qualified workshop.
An electrical system fault can cause vehicle
functions to fail, thus impairing the vehicle’s
stability – risk of accident! Switch the vehicle
off and do not drive on. Seek professional as-
sistance.
The 12-volt vehicle battery has been developed
for use in its installation location and is equipped
with safety features. If a 12-volt vehicle battery
has to be replaced, please enquire about the
electromagnetic compatibility, capacity and the
required maintenance, performance and safety
features of the new 12-volt vehicle battery be-
fore purchasing it from your qualified workshop.
The gas vent on the 12-volt vehicle battery must
always be located on the side of the negative ter-
minal. The gas vent on the side of the positive
terminal must always be sealed.

Information on batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace-
ment, etc. must be carried out by a qualified
workshop ð
.
Several batteries using different technologies are
fitted in your vehicle:
When replacing the 12-volt lead battery, use only
maintenance-free 12-volt lead batteries to
standards TL 825 06 and VW 7 50 73. These
standards must be from October 2014 or later.

If the vehicle is not used for long periods
WARNING
The 12-volt battery gradually becomes dis-
charged if the vehicle is left standing for long pe-
riods. To ensure that the vehicle can be started,
– Any work on the batteries and electrical sys-
tem in your vehicle entails a risk of injury
