For anyone who starts in the cold...

So,
Is the "sub-zero start" something that only works under 0 degrees?(and are we talkin 0'c or 0'f) or is it usefull in temps like 20's and 30's too?

also, is the fluid from it what's heating the interior too? like just the regular climate control i mean...I've heard it does, but that dosent seem to make alot of sense so, let me know.
thanks

The sub zero doesn't work and never has. In fact Mazda issued a TSB that instructed dealers to remove the units from any cars in for service.

No, the sub zero fluid (basically a really rich mixture of coolant and water) has nothing to do with interior heat. It is supposed to spray into the lower intake manifold to de-ice and lubricate...
