– On ly
use a charger which is compatible for
use with 12 V nominal voltage batteries.
The charge must not exceed a voltage of 15
V.
– Now connect the battery charger to the
power socket and switch on.
– After charging the battery: switch off the
battery charger and disconnect the power
socket cable.
– Finally disconnect the charger cables from
the battery.
– Replace the battery cover correctly.
– Close the bonnet ››› page 199.
Important: Before you charge the battery
make sure you read the manufacturer's in-
structions for using the battery charger. WARNING
Never charge a battery that has frozen: re-
place battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment to charge the battery. Replacing the battery
The new battery should have the same speci-
fications (amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy
››› page 191.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop. CAUTION
● Some vehicles, for example those with the
Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tached to the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage. ●
The battery holder and clamps must always
be correctly secured.
● Before starting any work on the battery, al-
ways observe the warnings listed under
››› page 206, Important safety warnings for
handling a vehicle battery .
● Do not forget to replace the battery cover-
ings, where applicable. It is a protection for
high temperatures. This in turn extends the
vehicle service life. For the sake of the environment
Batteries contain toxic substances includ-
in g s
ulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.
Make sure disconnected batteries cannot tip
over. Sulphuric acid could be spilt! 207
