Stop/Start Vehicles - From 2010 My

To support the Stop/Start system, a number of changes have been made to the logic and operation of climate control system within a Stop/Start cycle to:

maintain occupant comfort
prevent windshield misting
conserve battery power.

This has been achieved by the automatic temperature control (ATC) module monitoring and varying when necessary, various climate control functions within a Stop/Start cycle. Refer to appropriate Starting System information.

To maintain the cabin temperature when the engine is shutdown in a Stop/Start cycle, an auxiliary electric coolant-pump has also been integrated into the cooling system to maintain the coolant flow through the cabin's heater core. The pump is directly hardwired to the ECM. On vehicles fitted with a FFH (fuel fired heater), the FFH coolant pump is utilized and activated via the FFH. Refer to appropriate Starting System information.

NOTE: From 2010 MY, the 'ECON' switch will be labeled 'A/C' to prevent confusion with the 'Eco' switch which operates the 'Stop/Start' and 'Gear Change Indicator' systems.
