curiousB Posted March 6, 2010 Share Posted March 6, 2010 Well it could be a cellphone with a missed (unanswered) call beep My car beeps if the engine is running but you walk away with the key in your pocket (electronic key version) as a warning not to drive away while leaving key at home. Not sure they had that feature in 2000. Could be one of the warning indicators in the dash, low fuel, low washer fluid, brake warning/malfuntion. But I thin that only beeps once then displays a visible message. Not sure maybe a couple suggestions to look at. Quote Link to comment Share on other sites More sharing options...
