IMPORTANT
When replacing the starter battery, in cars
with Start/Stop function, a battery of the
correct type must be fitted, EFB12 in cars
with manual gearbox and AGM13 in cars
with automatic gearbox.
When replacing the support battery, a bat-
tery of AGM type must be fitted.
IMPORTANT
If the starter battery is replaced, make sure
you replace it with a battery with the same
cold starting capacity and type as the orig-
inal battery (see the label on the battery).
NOTE
•The battery's container size should be
consistent with the original battery's
dimensions.
•The battery's height is different
depending on size.
WARNING
•The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.
•The battery contains sulphuric acid,
which can cause serious burns.
•If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.
IMPORTANT
When charging the starter battery or the
support battery (p. 373), only use a mod-
ern battery charger with controlled charg-
ing voltage. Fast charging function must
not be used since it may damage the bat-
tery.
IMPORTANT
If the following instruction is not observed
then the energy saving function for info-
tainment system may be temporarily dis-
engaged, and/or the message in the com-
bined instrument panel's information dis-
play about the starter battery's state of
charge may be temporarily inapplicable,
following the connection of an external
battery or battery charger:
•The negative battery terminal on the
car's starter battery must never be
used for connecting an external bat-
tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting (p. 267) for a descrip-
tion of how the cable clamps must be
attached.

13 Absorbed Glass Mat.
