We live on the top of a mountain, at 1850 ft elevation. Almost anywhere we go, we start out by descending about 1000 ft down a 3 mile hill, with a traffic light at the bottom. We have noticed that everytime we make the descent, our IMPG display drops to 0 about half way down the hill, and stays at zero until we stop at the traffic light at the bottom. From then on, it appears to behave normally. This is a 7% grade, and regen is on all the way down... we should be consuming no fuel, or just a little to warm the engine.

Is this normal?


Thanks
