CAUTION
It is not possible to charge another vehi- cle's battery by supplying current throughthe charging points. Using the chargingpoints to charge another vehicle's batterycould cause a fuse to blow, which wouldcause the charging points to stop working.
CAUTION
Only a modern battery charger with con- trolled charge voltage should be used tocharge the starter battery. The rapid charg-ing function should not be used as thiscould damage the battery.
NOTE
If both the starter battery and the hybrid battery are discharged, both batteries
must be charged. In such cases, it is notpossible to charge only the hybrid batteryfirst. The starter battery must have a certain level of charge for it to be possible tocharge the hybrid battery.
CAUTION
Failure to observe the following could cause the infotainment energy save modeto temporarily stop working and/or a mes-sage in the driver's display regarding thestate of charge of the starter battery maybe temporarily incorrect after an externalstarter battery or battery charger has beenconnected:
The negative battery terminal of thevehicle's starter battery must
never be
used to connect an external starterbattery or battery charger – only thevehicle's negative charging pointshould be used as a grounding point.

NOTE
If the starter battery becomes discharged too many times, it will shorten its servicelife. The service life of the starter battery is affected by several factors, such as drivingconditions and climate. The startingcapacity of the battery reduces graduallyover time. The battery must therefore berecharged if the vehicle is not used or along period of time or if it is only drivenshort distances. Severe cold further limitsthe starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery shouldbe connected to a battery charger withautomatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.
