Auxiliary Climate Control: General

The auxiliary climate control system provides additional air conditioning for the second and third row seat occupants. The auxiliary climate control system consists of:

• An auxiliary climate control assembly.
• A refrigerant circuit.
• A heating circuit.
• A distribution system.
• An ACCM.

The automatic temperature control (ATC) module, of the main air conditioning system, is also used in the control of the auxiliary climate control system. For additional information. Refer to Control Components article.

Cabin air is recirculated through the auxiliary climate control assembly, where the air is temperature regulated and then directed through the distribution system to registers in the roof, on the C pillars and on the left side of the loadspace. The volume, temperature and distribution of the air from the auxiliary climate control assembly can be manually controlled by the ACCM or automatically controlled by the automatic temperature control (ATC) module.
