Can anybody tell me what this is? Voyeger 2.8 CRD LX three lines apear on my dash, the hand book says its the aux heater, what is this? and how do you switch it on and off.

 

there is no off switch turn the inside temp down is the only off switch as such (before you start it as once it is running it will stay running) as it's a diesel it takes a long time to worm up so you have an extra diesel heater.

 

Thanks very much, very helpfull.
