High Altitude setup

Hi,
How can you tell if your '03 Expy has been set up for high altitude operation? Is there any method other than the dealer checking the computer?
thx

I believe the computer automatically compensates for altitude changes. But now that you mention it, I may recall having read something regarding a certain bias to high altitutes.

Hi,
That is what I am trying to find out. The 01, 02 Expy info clearly shows an option called "High Altitude Principal Use". I can't locate a similar option for the 03. I purchased the car as a certified used vehicle and I am wondering if it was delivered with this option or did the 03 year not even have that option. Maybe in 03 the computer does it automatically as you suggest.
Gary
