We therefore recommend that you have the battery checked and, if necessary,
recharged by a specialist garage before the start of the winter.
CAUTION
For technical reasons, on vehicles with the description "AGM", the electrolyte
level cannot be checked.
Note
The battery electrolyte level is also periodically checked by a specialist garage
as part of the Inspection Service.
Charging

Read and observe and
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 =
"positive", black = "negative").
›
Plug the mains cable of the charger into the power socket and switch the
charger on.
›
Once charging is complete: Switch off the charger and remove the mains ca-
ble 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 battery cables if you are recharging the
vehicle battery using low amperages (for example from a mini-charger). Refer
to the charger manufacturer's instructions.
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
Both cables must be disconnected before charging the battery with high
amperages, known as "rapid charging".
The vent plugs of the vehicle battery should not be opened for charging.
WARNING
"Quick-charging" the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
