Active handling warming up
I was driving in 112 degree temp in the socal desert near palm springs. Got a bite to eat and left the car running w/ AC while parked. I got the "Active handling warming up message" and it never went away. Shut the car down turned it back on and it was still there. Turned the ignition on and off a few times and it went away. What gives?

I believe active handling warm up is referring to the computer getting a baseline reading when the car is first driven, it is not related to any temperature reading. I understand the system controlling the active handling needs to have the car driven in a straight line for a few seconds to get this baseline; I guess this allows it to know when the car is yawing too much later on.
Turning the car on and off a few times probably forced the car to dump the warning from memory.
Someone correct or clarify if I am wrong or incomplete.

Happened to me Sat night at a car show also. I was driving away from the show and it said "active handling warming up". It stayed there for maybe 10 seconds and went away... I forgot about that till I saw this post...

Thanks guys. I did come off the offramp pretty hard, may be that caused it. Has not reappeared since.
I do not know if this is true for the GM DIC, but on Chryslers, if you do the ignition on/off a few times within 10 seconds, it gives you a readout of all known errors. Any experience/suggestions?

happens to me now & then too, but mostly when i'm in parking garages for some weird reason. 
long story short, don't worry about it. i posted this same question about a year ago when i first got my z and people said the same thing (to not worry about it). also, someone let me know that lo & behold, this item is discussed in the owners manual! i actually opened it up and read a couple of things, including about this unique feature of active handling warming up--go figure! :o

Mine does it too if I am going parking lot slow, for an extended time. Not sure why but it does happen at very slow speeds. I though someone posted a good tech review about it a ways back but I can not find it. If yuo check your DIC codes and see this in the H side, no worries, clear it and enjoy.

There is a direct relationship between slower speeds and driving in enclosed parking lots down down ramps as my 03 Z did this all the time in enclosed concrete parking garages in the CITY while exiting and my 02 does it once in a while but MUCH LESS Frequently!!!

To display your codes all you have to do is turn the key, then press the options button and while holding that button press the fuel button 4 times and then you can release the buttons and it will then automatically give you a read out of all you DIC codes. You can observe your codes and then reset them if you like. Keep in mind that resetting the code does not fix the problem.

My Z does this 85% of the time I drive through my fiance's apartment complex parking lot. It must have to do with the fact that I cruise through there very slowly as the pavement sucks and some of the people who live there think 25mph is a safe parking lot speed; not to mention the 2 blind turns and the fact that people back out of their spots without even looking!!! The funny thing is it hardly ever does it anywhere else, I must just drive a little quicker elsewhere

To calibrate wheel speed sensors relative to each other (to sense turns, radius of turns, etc), the computer is looking for 100' of driving with the steering wheel straight within the first 30 seconds of driving. If you're driving through a parking garage/lot or autocrossing where the course turns immediately and the computer doesn't see this, you'll get the "active handling warming up" which tells you active handling is not available so drive accordingly. This is because it can't make active handling calculations without that info. Once you've driven that 100' with wheels straight, it enables active handling. If you ever disconnect the steering shaft from the steering rack, it is imperative the steering wheel not be turned or when you reconnect the coupling, the computer will sense the steering wheel is turned even though you are going straight. This means the computer will never "see" you going straight and active handling will never be enabled....don't ask me how I know. :bb Damn the school of hard knocks!

I've noticed it coming out of the parking garage at work lately. It has those "turnstyle" type exits, so you drive in a circle for 4-5 levels before you exit. If I start the car and get moving too quick, it seems to do that until I get out and on the straight away for a few seconds, then it goes away. Since I have never seen it prior to this, I had been attributing it to the exit ramps and corresponding turning.

Happens to me quite often when I am first leaving my garage. If I drive away very slowly I always get the warning, but it goes away after I get up to speed.
I had it happen a couple of times it does what it wants and goes out.

Coincidently, I have had the message come up a few times this summer. It comes up under different start up driving conditions. Only constant was it was @#$ hot, but I doubt that had anything to do with it.
By the way, Chrysler products, at least through 2003, turn the key to the on position and then off three times (don't turn over the starter and leave it in the on position on the third try) and you will get a code dump. A lot cheaper than than OBDII readers .
