The car has an advanced coolant system which regulates the temperature of the electric drive and in the passenger compartment. The system is available regardless of whether the car is parked, being charged or driven.

The coolant system is a closed system and all maintenance must be performed by a qualified technician. Contact a workshop1 as soon as possible if you get a warning message saying a service is needed.

Coolant must not be swallowed. It can cause damage to kidneys and other organs. The product contains, among other things, ethylene glycol, inhibitor and water.
