MAINTENANCE AND SERVICE

CAUTION
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery and support battery. The rapid
charging function should not be used as this
could damage the battery.
CAUTION
Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery charger has been connected:
•
The negative battery terminal of the vehi-
cle's starter battery must never be used
to connect an external starter battery or
battery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too
many times, it will shorten its service life.
The service life of the starter battery is affec-
ted by several factors, such as driving condi-
tions and climate. The starting capacity of the
battery reduces gradually over time. The bat-
tery must therefore be recharged if the vehi-
cle is not used or a long period of time or if it
is only driven short distances. Severe cold fur-
ther limits the starting capacity.
To keep the starter battery in a good condi-
tion, the vehicle should be driven at least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging.
A starter battery that is always kept fully
charged has the maximum service life.
Location
The start battery is located in the cargo compartment.
WARNING
If the starter battery is disconnected, the func-
tion for automatic opening and closing must
be reset to function correctly. A reset is
required in order for the pinch protection to
work.
