This is the second time this week this happened. I get to the car and it's completely dead... very dim interior lights. I jumped it and it started right up.. leaving this message on the dash. Parking malfunction. Park on level surface. Be sure the parking brake is secure. Okay it is on a flat surface. I don't use the parking brake. Today after I jumped it, it fired up but when the cables were removed it died. So I jumped again but this time put the parking break on and then off. Worked. After the first time I took it to the mechanic. He checked the battery which is not old and it check out very good. Any thoughts ?? do I need to take it to Toyota ?
