Operation in winter
The battery has to provide greater amounts of electricity during the winter. It also
has only part of the initial power output at low temperatures that it has at normal
temperatures.
A discharged battery may already freeze at temperatures just below 0 °C.
We therefore recommend that you have the battery checked by a specialist ga-
rage before the start of winter and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery.

Charging the battery
A properly charged battery is essential for reliably starting the en-
gine.
–
Read the warning notes
⇒
in General information on page 196 and
⇒
.
–
Switch the ignition and all electrical components off.
–
Only for “quick-charging”: Disconnect both battery cables (first of all “nega-
tive”, then “positive”).
– Carefully attach the terminal clamps of the charger to the battery terminals
(red = “positive”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and
switch on the charger.
– When charging is completed: switch the charger off and unplug the mains ca-
ble from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
–
Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of the battery if you recharge
the battery using low amperages (as for example from a
mini-charger ). Please al-
so refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which
should be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called “
quick-charging ”.
“Quick-charging” a battery is dangerous
⇒
in General information on page 196.
It requires a special charger and specialist knowledge. We recommend having the
quick charging of vehicle batteries undertaken by a specialist garage.
A discharged battery may already freeze at temperatures just below 0 °C
⇒
. We
recommend that you no longer use a battery which has thawed out because the
casing of the battery may be cracked through the formation of ice and this would
allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
●
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
● Never charge a battery which has a too low electrolyte level - risk of explo-
sion and caustic burns.
CAUTION
On vehicles with the “START/STOP” system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth

Disconnecting and reconnecting the battery
On disconnecting and reconnecting the battery the following functions are initially
deactivated or are no longer able to operate fault-free.
