Long-term storage of vehicles with hybrid batteries
To minimise hybrid battery degradation during prolonged storage (longer than 1 month) of the vehicle, a charge level of approximately 25% is recommended, as indicated on the driver display.
Proceed as follows:
If the state of charge is high - run the car until approx. 25% remains. If the state of charge is low - charge the battery until a level of approx. 25% is reached.
If storage has lasted longer than 6 months or the hybrid battery charge level is significantly lower than 25% - charge the battery to approx. 25% again to compensate for the natural self-discharge that occurred during the prolonged storage. Continuously check the charge level in the driver display.
For handling the starter battery in connection with long-term storage, see "Using jump starting with another battery".
Note
Choose the coolest location possible for the vehicle in order to minimise aging of the battery during long-term storage. During summer the vehicle should preferably remain indoors or outdoors in the shade, depending on where the temperature is lowest.
