Winter time
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C.
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
Note
The battery acid level is also checked regularly by a specialist garage as part of
■
the inspection service.
For technical reasons, the electrolyte level cannot be checked in "AGM" vehicle
■
batteries.
Vehicles with a START-STOP system are fitted with a battery control unit for
■
checking the energy level for recurring engine start.
Charging the vehicle battery

First read and observe the introductory information and safety warn-
ings on page 200.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a "quick-charge", disconnect both battery cables (first
"negative", then "positive").
›
Attach the terminal clamps of the charger to the battery terminals (red = "posi-
tive", black = "negative").
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first "positive", then "negative").
It is not necessary to disconnect the cables of the battery if you recharge the ve-
hicle battery using low amperages (for example from a mini-charger). Refer to the
instructions issued by the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, known as "rapid charging".
The vent plugs of the vehicle battery should not be opened for charging.
Replacing the vehicle battery
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be
purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
WARNING
"Quick-charging" the vehicle battery is dangerous and requires a special

charger and specialist knowledge.
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 » page 222, Jump-starting in vehicles with the START-STOP
system.
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Disconnecting and reconnecting the vehicle battery

First read and observe the introductory information and safety warn-
ings on page 200.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.
Operation
Electrical power window (operational faults)
