Positive charging point
Negative charging point
IMPORTANT
When charging the starter battery and the
support battery, only use a modern battery
charger with controlled charging voltage. Fast
charging function must not be used since it
may damage the battery.
IMPORTANT
If the following instruction is not observed
then the energy saving function for infotain-
ment may be temporarily disengaged, and/or
the message in the driver display about the
starter battery's state of charge may be tem-
porarily inapplicable, following the connection
of an external starter battery or battery
charger:
•
The negative battery terminal on the car's
starter battery must
never be used for
connecting an external starter battery or
battery charger - only the
car's negative
charging point may be used as the
grounding point.
NOTE
The life of the battery is shortened if it
becomes discharged repeatedly.
The life of the battery is affected by several
factors, including driving conditions and cli-
mate. Battery starting capacity decreases
gradually with time and therefore needs to be
recharged if the car is not used for a longer
time or when it is only driven short distances.
Extreme cold further limits starting capacity.
To maintain the battery in good condition, at
least 15 minutes of driving/week is recom-
mended or that the battery is connected to a
battery charger with automatic trickle charg-
ing.
A battery that is kept fully charged has a
maximum service life.
