right above the fuel guage on Runner's pic is an orange/yellow icon.
That's the one on mine that comes on for x amount of seconds. I haven't timed it, but it is definitely on a timer.
Looks very similar to a glow plug icon.
I thought I had 4 icons on the right side, but, now that I've looked at it some more, the 4 are across the top. (and **** if those guages aren't blue on a nice sunny day !)
