On my Smart 453 ED there is a two gauge instrument stalk to the left of the steering wheel. The top gauge has a needle that shows power use and regen when slowing or braking, above that gauge is a series of lit orange dashes that arc over the top. Usually the orange dashes are fully lit in all circumstances until our recent cold snap. When temps dropped below freezing I noticed that at least the left two orange dashes were not lit. They came back on as I drove the car more and the performance seems fine. Just curious what those orange dashes represent? I'm assuming it has something to do with the battery but exactly what I don't know.
