My battery recently died on my 1995 Range Rover... After replacing the battery the air suspension doesn't level the truck or even work any more. The front right seems to be in the high setting and the left rear looks to be on the bump stops. On the suspension control switch inside the RR there are two light on now... one for the regular ride height and one for the loading setting (lowest setting). Pressing the switch does nothing at all. There is now a message on the dash that says "SLOW: Don't exceed 35 mph". Is there any reset that must be done that i can perform at home or am i forced to take the RR back the dealer every time the battery dies to reset all of the computers??? Can anyone recommend where/what to buy as a good shop manual to work on this RR? Thanks for the help
