MAINTENANCE AND SERVICE
636
IMPORTANT
When charging the starter battery, only use
a modern battery charger with controlled
charging voltage. Fast charging function
must not be used since it may damage the
battery.
NOTE
If both the starter battery and the hybrid
battery are discharged then
both batteries
must be charged. In such a case, charging
only the hybrid battery first is not possible.
In order for the hybrid battery to be
charged the starter battery must have a
certain state of charge.
IMPORTANT
If the following instruction is not observed
then the energy saving function for info-
tainment may be temporarily disengaged,
and/or the message in the driver display
about the starter battery's state of charge
may be temporarily inapplicable, following
the connection of an external starter bat-
tery 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
climate. Battery starting capacity decrea-
ses 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 rec-
ommended or that the battery is con-
nected to a battery charger with automatic
trickle charging.
A battery that is kept fully charged has a
maximum service life.
