Hilux SR5 Cold Start Button

Cold Start button..?? Where are they..? I haven't seen one in mine..

The cold start button is down near the elect mirror switch.
SR5 Hilux 2006.

If you keep the heat button in the on position the engine will run fast when cold, once warm it will come back to normal RPM.

If you start it warm, the RPM should be normal even if button is on.

It should only run fast when cold, the sensors work it out.

Well this is what mine does anyway :-)

Maybe we should read the user manual :-)

Ahh yes the Powerheater Switch..! Thanks..

Might be worthwhile reading the manual although it may not give any technical info other than "increases engine revs at idle until engine is warmed to X temp".
On the 6.2 in the humvee it automatically advances the timing a few degrees when the engine is cold to aid cold starting, the timing returns to normal as soon as the temp gauge starts to move.
Quite obvious when it is on as the engine has a deeper 'diesel knock' and pulls better low down.
