They still have pre-heaters, which equate to battery juice being used up.
I have a Strada 4D56. When I turn on the engine, the heater (idiot) light just flashes then turns off. Basically this will tell you that the engine is ready to start, di ba? What others would not know is that the heater relay is still in the "on" position. And this relay dis-engages a good 5-10 seconds after the heater light went off!
I don't know if its the same with a Montero, but upon turning my engine on, I hear a slight "knock" ... that's the heater relay energizing. It will continue to energize, way after the heater light went off. In about 10 seconds, the heater relay will dis-engage, (you will hear it "knock: again).
That's when I start my engine.
