MAINTENANCE AND SERVICE

CAUTION
It is not possible to charge another vehicle'sbattery by means of current through thecharging points. Using the charging points tocharge another vehicle's battery could causea fuse to blow, which would cause the charg-ing points to stop working.

CAUTION
Only a modern battery charger with controlledcharge voltage should be used to charge thestarter battery. The rapid charging functionshould not be used as this could damage thebattery.

NOTE
If both the starter battery and the hybrid bat-tery are discharged, both batteries must becharged. In such cases, it is not possible tocharge only the hybrid battery first.
The starter battery must have a certain levelof charge for it to be possible to charge thehybrid battery.
CAUTION
Failure to observe the following could causethe infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
The negative battery terminal of the vehi-cle's starter battery must never be usedto connect an external starter battery orbattery charger – only the vehicle's neg-ative charging point should be used asa grounding point.
NOTE
If the starter battery becomes discharged toomany 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 thebattery 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 itis 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 least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging.
A starter battery that is always kept fullycharged has the maximum service life.
