The last stretch of my drive home is a downhill slope a couple miles long. It isn't particularly steep but the speed limit is only 25, so you have to ride the brakes to stay legal. Tonight I thought I'd drop the car into "B" to see what it felt like and to check if it would noticeably boost the charge in my battery. The car slowed significantly, but as I was coasting down the hill either the engine or the VCT (it happened quickly, so I couldn't tell which) started "racing," as though I was pressing the accelerator. It was quite loud and disconcerting, so I immediately popped the car back into "D." The noise quieted right down and the car seemed fine, so I continued home. I have used "B" mode only once before and that was at about 70mph on a much longer, steeper grade and I didn't notice anything like this happening. Can anyone tell me what was going on? Was this normal? Any advice will be greatly appreciated.
Thanks,
