System Description

INFOID:0000000004211742

• An inverter cooling system that is independent from the engine cooling system has been provided to cool the

inverter, MG1 and MG2.

• This inverter cooling system activates when the power supply status is switched to the READY ON state.

• A sub radiator, which is exclusively used for the inverter, MG1 and MG2, has been provided in front of the

radiator and condenser assembly (for the engine cooling and A/C).

Specifications

• The inverter cooling system is filled at the factory with a high-qual-

ity, year-round, anti-freeze coolant solution. The anti-freeze solu-

tion contains rust and corrosion inhibitors. Therefore, additional

inverter cooling system additives are not necessary.

CAUTION:

When adding or replacing coolant, always use only Genuine

NISSAN Long Life Antifreeze/ Coolant or equivalent with the

proper mixture ratio of 50% anti-freeze and 50% demineralized

water/distilled water.

Other types of coolant solutions may damage your inverter

cooling system.
