This guide will show you how to enable ‘Pollution Mode’ on your Holden VE Commodore. Suits most Series 1 and Series 2 models.
When enabled, pollution mode automatically selects air re-circulation when the vehicle speed is less than 15 km/h. This is aimed at preventing exhaust fumes entering the cabin in stop/start traffic or whilst waiting at the traffic lights. Upon reaching a speed higher than 15 km/h, the air re-circulation is turned off. This happens continuously whilst pollution mode is enabled. It essentially allows outside air to only enter the cabin when the vehicle is moving at speed.
