Hybrid-related information

Long-term storage of vehicles with hybrid batteries

Updated 7/23/2018

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 in the combined instrument panel.

Proceed as follows:

Select the "Hybrid" theme for the combined instrument panel. For information on menu navigation, see Combined instrument panel.

If the state of charge is high - run the car until approx. 25% remains. If the state of charge is low - press the POWER button and run the car until approx. 25% is achieved. For more information on the drive modes, see Drive system - drive modes.

If storage has lasted longer than 6 months or the hybrid battery's charge level is appreciably lower than 25% - start the engine in POWER drive mode and leave it running for at least 10 minutes until the state of charge has stabilised at around 25% again.

This compensates for the natural self-discharge that occurred during the prolonged storage. Check the charge level continuously in the combined instrument panel, see Charging the hybrid battery - starting.

If the car is locked in and cannot be driven, and the hybrid battery's charge level is significantly below 25% - charge the battery for approx. 45 minutes at the lowest level, depending on the state of charge. Check the charge level continuously in the combined instrument panel.

For handling the starter battery in connection with long-term storage, see Starter battery - general.

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.

Important

During long-term storage, the charging cable must not be plugged into the car's charging input socket.

Old fuel

Old diesel fuel (from approx. 5 months and older) in combination with condensation can, in some circumstances, lead to algal and bacterial growth in the fuel system and/or oxidation of the fuel with the risk of operational disruption as a result. For more information, see Energy flow.
