My altimeter shows 150ft constantly.
Anybody know how to reset/recalibrate it please?

But I do admit I am not aware how it works. I also assumed it calculated it from the GPS. as my Garmin does.
( I am thinking of gluing my Garmin onto the screen it would be easier o use than the built in nonsense !!! )
However it works, it should not be stuck at 150ft (and never alters) when I live 27ft above sea level. My girl friend lives 369 ft above sea level in North Dorset but my car still says 150ft!
Poole Mitsu have not come across this problem.

I don't see how a barometer could infer height giving the variance within the day based on changing weather conditions
raymie said:so far all the posts I see mention it working by GPS such as http://mitsubishiforum.com/forum/mitsubishi-outlander-10/altimeter-sensor-29602/
not a reliable guide however perhaps to reality
Mine does the same - it consistently insists the car is flying at an altitude of 50 m. whilst in fact it is driving below sea level.Carnut said:On the Gx4h there is an altimeter.

Initial reading was 350ft with a pressure of 999mbar
During the drive which are one stage by definition was almost down to sea level since I was driving along side the sea!! the readings varied but...
Altimeter only varied by units of 100ft, so read 150ft min, 250ft and 350ft only
Baromenter only varied by units of 5 and with the same number of readinging, 999, 1004 and 1009
So despite the manual saying that some height readings are from the GPS (Perhaps only on the sat nav screen?). The altimeter and barometer seem limited to a certain range (which may depend on the starting reading, I need another test to check that) and are limited to a rather large degree of inaccuracy,
In the case of the orginal poster. if you are not driving somewhere with a large height difference then it staying at 150ft would be consistent with my first test where at around 20ft above sea level to say 200ft it said 150ft.

raymie said:I think basically it is fair to say that the components in the outlander are far too vague to be reliable, if it bears out that a) it does use air pressure and b) it does so only in units of 5mbar then the height will be out almost all of the time.
Right now my home station is reading 996.3. yesterday it varied between 999 and 1018, which would give my house varying in altitide by over 600ft in the space of a day.
