    Up here in the UK our Toyota manual tells us its for extremely cold temperature starts when you need to put a great deal of load on the alternator i.e lights, aircon, heated rear windows etc all flat out.

      oversupply of idle-up switches?

          I had i look at mine and found wires were connected to the switch. I finally got the switch to work. On cold mornings it does "idle up " the engine till its warm. Obviously a feature built in for an non Australian market.

            The changing of a light globe continues?
            It is a D4D thing.
            Just go back and see how many agree with a cold start function!

                All the idle up switches I have been associated with were to do with the air conditioning. If you switch it on when you have the air conditioner on it should bring the revs up above idle while you are stationary. Once you move off, everything should come back to normal. Diesels don't like to idle for too long because they glaze up in the bores, hence the idle up switch.

                  I have the "Idle up" button in my D4D GX. i have used it on cold mornings and it immediately increases the revs. (i couldn't find anything in the manual either (despite looking and looking).
                  It only works when the car is stationary. If you are moving even slightly (say in neutral), it cuts out and the revs return to normal range. When you take off, it cuts out and when you get to the traffic lights and stop, it increases the revs again. It seems to do this until the engine temp increases before it cuts out all together. In summary: it only increases revs for a few minutes, won't work when moving (though it starts again when stopped, if engine is still cold) and cuts out when engine temp increases.

                    I have just purchased a D4D and my dealer explained it as a fast idle control
                    when starting the engine & is normally not required (It may only work when the engine is very cold)

                    Drummo thanks for the support,
                    I would say we can now all agree. That is what my dealer told me it was for, when I first took delivery back in February this year. ("It is a D4D thing", not earlier models)

                    Haven't things changed, as I only had to wait three weeks for delivery after I had placed my order.

                      Idle up Switch

                      Hi,
                      I am new to the forum, but I have an answer to the idle up question.
                      I have just purchased a new September build prado which has the said switch and again not listed in the manual.I contacted the local agent and was told is is for cold weather starting where it increases the idle rpm until the engine reaches a set point then cuts the rpm back to normal.It was suggested to me that this switch is not required when driving in Australia.
                      Regard - David

                          Hi davidb,
                          That is correct only needed for cold weather starting, if you do any Alpine snow holiday's it may be handy :wink:

                            Yep, tried mine first thing this morning and it worked. Tried it after I got home and it obviously wasn't required as nothing happened. .

                              Idle up.... hrmm could that be something to do with adjusting your engine Idle revs. Like on my old Hilux its a screw thingy that you tweak to make the engine rev higher when sitting at idle (traffic lights or something). Just a thought......

                              D'oh... you guys already said it. Forget I said anything.
