Can anyone tell me what the white indicator light mean that looks like a gauge with the needle at 0? It is shown on page 5 of the Smart Start Guide but it is not described in the glossary. Mine just came on today and won't turn off. The car has been sitting for close to an hour with the windows up and doors locked. I went for a drive at 5:30 am this morning and it was not on. About an hour and a half ago I put the car up on ramps and it came on after getting the car on the ramps and has not turned off since. It did not come on at all yesterday.
