interior heater
 

hi, there is a button on the heater panel with max written on it! if i push it it turns on the heater but on low i think, nothing else lights up just that actual button when pressed! but it turns on even with no key in the ignition! anyone know whats it for? thanks in advance

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
