My dealer said that I must idle my 2010 FX until the blue temp icon goes off, or about 5 minutes, before I can drive away. If the outside temp is below 40 degrees F, that is.

Here in Minnesota, that's a lot of waiting. I usually wait a minute or two and drive off slowly. Is there anything to this rule?

Thanx for the advice. :confused:

Don't know anything about the new model but think you must have got the wrong end of the stick from the dealer. That temperature is above freezing and should not prove a problem to any modern (or old) car. If what you say is correct then they wouldn't sell any cars!.

Best way to warm up a car is to drive off immediately at a gentle pace. Starting and then allowing an engine to just idle takes too long for the engine to reach operating temperature and will rapidly increase engine wear.

Revving a cold engine is asking for problems. I start mine up and let it idle for about 10 to 15 seconds. then I drive away gently and try to keep the rpms low until it warms up.

Exactly. Instead of putting the C-H needle, they put an idiot light to tell you that when it is blue, don't beat it and that when the red light comes on, well you MIGHT have blown your engine!!!!

I like gages.....period.

Totally an opinion NOT a fact.
The engine will reach operating temperature just fine at idle and not have to pump cold thick oil through it.

The temperature in a winter morning here can easily hit -15'C. For a cold start, I usually idle until the rpm drops around 1000 then beginning driving, it's about 1 minute or 2, the light is still blue though.
