Checking the inverter coolant level (PHEV)
If frequent additions are required, we recommend that the system be inspected by a professional workshop. Kia recommends to visit an authorised Kia dealer/service partner.
The inverter coolant level should be in between MAX and MIN when the engine is cooled down. When the coolant level (in the reservoir) is low, we recommend that you contact your authorised Kia dealer/service partner. Use only designated coolant water for electric vehicles.
Adding other cooling substances or water might lead to inverter cooling system degradation or even failure.
Changing the coolant
We recommend that the coolant be replaced by an authorised Kia dealer according to the Maintenance Schedule at the beginning of this chapter.
Use caution when working near the blade of the cooling fan. The electric motor (cooling fan) is controlled by coolant temperature, refrigerant pressure and vehicle speed. It may sometimes operate even when the vehicle is not running.
