on my 08 f150 fx4 supercrew where the temp and mileage is shown if you hold down the little button to clear the trip, there will be a menu come up with zones. It goes up to about 15 I think...

What are these zones for? can they be programmed for something?

 

page 124 in your owners manual

it is there to help you manually select a zone if your compass calibration is off.

the truck should automatically calibrate itself most of the time but its you find it is consistently wrong you have the option to set it yourself.

 

oooo. ok!

I really wish the truck would show how long it'd go till it ran out of gas. haha.

 

my dad's 08 superduty shows miles to E .... very nice feature!
