Starting From Cold

Starting From Cold In AUTO Working Mode
- Conditions are appropriate for cold start when outside temperature is 5 °C (9 °F) or more below the preselected temperature and the ACC control module has calculated that a blended air temperature greater than +80 °C (176 °F) is required.

- Air distribution starts in defrost position, and then goes to defrost/floor position as blended air temperature increases.

- When starting from cold, fan current is also dependent on blended air temperature and there is a preprogrammed maximum fan speed. Fan speed varies within the shaded area on the diagram above. Even if the ACC control module has calculated that a higher fan speed is required, speed will never exceed the preprogrammed maximum speed, in graph. This maximum speed can be adjusted using the ISAT scan tool.
