Our 06 GWV Sprinter came with a GWV binder full of information on the upfit but there isn't any owners manual for the MB (Dodge) chassis.
Took me a while just to figure the basic driving controls out (accidentally left headlights on - no AUTO position on German vehicles..) I have downloaded some excellent PDF's online but I don't know what I actually have for options.
For instance I have a light on the instrument panel that says ESP so I assume it has the Electronic Stability Program.
Also there seems to be some type of aux heat that may run off the diesel. There is a button that boosts the heat and one the says REST that I think uses residual engine heat after being turned off.
