This system gives access to the following elements:
Permanent display of the time and the exterior temperature (a blue
warning lamp appears if there is a risk of ice).
Heating/air conditioning controls.
Vehicle functions and equipment setting menus...
Load distribution
Distribute the load in the trailer so that the heaviest items are as
close as possible to the axle, and the nose weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus reducing engine performance...
