This afternoon as I headed to run errands I noticed that instead of a solid line under the PRND indicator, it displayed line 10 dots from left side to just past the D. Here is a link to the manual, page 53, documents the reason for this. Some of the reasons could be, potentially due to high battery temps, high state of charge (looks to be that in this case), or some other variable with the battery. Battery charged to 100% could also provide no regeneration (the car will coast), and showed even more dots than that until battery drained a bit. Then the regeneration returned and the dots changed to the line. Cold weather can also affects the battery charging.
