With the engine running - the Max button gives you maximum cooling (A/C on & heating off). With the engine recently switched off (if outside temp is below 15°C) it brings on the fan low and circulates the coolant through the heater box (allows occupants to keep warm for a while with engine off using residual engine heat).

thanks brian, i was just a bit confused when it come on when i accidently pushed it! think i'd be worried about battery draining to have it on lol
