well when you disable the DSC the parking brake and DSC light come on yellow. This might mean there is something wrong with the DSC so go to the dealer and have them look at it.
Why is breaklight yellow?
I was driving then all of a sudden the break light turns on and its yellow along with another green light. So I stop and pull the E brake up and then it turns to red, so I put it back down and then it turns yellow again. So I try to turn the car off and then back on again and then it went away! What's up with my car....or should I ask what's up with me? TIA!
