today, I was sitting in traffic and my ABS, Emergency Brake and Battery lights flashed on the dashboard. The car was making a funny noise under the hood (it was a brief hydraulic kind of noise), which after reading the manual, I suspect was the ABS diagnostic system. The manual said it was normal for this test to happen periodically, at slow speeds when I first start the car. In thise case however, the dashboard lights would come on, then disappear and then come back on intermittently. I got off the highway and out of traffic and the lights went away.
