The RDX Technology model also
adds a power passenger's seat and a blind - spot warning system, and the base RDX has new standard features including heated front seats and
air -
conditioning vents for the rear seat.
Imagine that you
add a few external factors to that imaginary warming kettle (a fan or
air conditioning vent blowing directly at the stove;
adding more water (hot or cold) to the kettle; a bucket of ice cubes sitting by its side; etc.) and what we have is a heating system that is affected by those other factors - but the water will still eventually boil unless the burner is turned off or turned down significantly.
