I just got a brand new EV battery on my 2013 Smart Fortwo Electric Drive. However the mileage range is still showing only 42 at a full charge.

Do I need to charge it up, press the reset button, and drive it for a good 60 miles or so? I have a vague recollection of doing this on another Smart EV (2015 model) but I just want to make extra sure I have the right idea.

Thanks. All the best!

See tech service bulletin SM-B-54.10/09
"To ensure that any losses in capacity are reliably determined during the test, the high-voltage battery has to undergo a specific discharge cycle before conducting the test step."


TL;dr: Drive the car to below 40% SOC; let the car sit off for more than 2 hrs; recharge the car to 100%; get new reading of range.

Jeb - we're talking about two different things here. Your bulletin talks about testing the HV battery using a test unit connected to the OBD port. Resetting the range on the dash is not affected/needed by or for that sequence. One can reset get the range reset by just charging the car.
