My travelings include going over a 5000 ft mountain in 15 minutes. New hybrid battery works great. But at the top or before the battery indication goes into the pink. When this happens I pull over and manually charge the battery as I don't like to drain the battery too much. Is there an adjustment or settings that can cause the system to charge the battery more aggressively ? The car does well otherwise. On flat ground it never goes below 50% (blue) and charges the hybrid battery well. No problems. New battery this year. Few minor problems (ie.. level sensor for headlights is warn out and occasionally it throws a (bad cat oxygen sensor).
there are not any adjustments available. battery charging is software regulated for efficiency, life expectancy and safety. did you buy a new, oem battery from a dealer? mountains can sometimes be a bit of a challenge for prius, especially an old one. they are not the most powerful cars in the world.
