Coolant
The vehicle has an advanced coolant system that regulates the temperature of the electric drive and passenger compartment. The system is available regardless of whether the vehicle is parked, charging or being driven.
The coolant system is a closed system and all maintenance must be performed by a trained technician. Contact a workshop1 as soon as possible if you receive a warning message that service is required.
