Summary

"General Electrical Systems Technical Service This Service Information bulletin supersedes SI B61 35 14 dated December 2014. designates changes to this revision SUBJECT Displayed Range Is Lower After Programming. After the vehicle is programmed with ISTA/P 3.53.3 (i-level I001-14-07-503), the displayed vehicle range in the instrument cluster is lower than prior to the software update. The actual range that the vehicle is capable of achieving on a full charge has not changed. The difference between the displayed range and actual range is always conservative, yet this difference varies based on driving profile. When driving primarily at highway speeds, the difference between displayed and actual range is within a few percent of each other. When driving primarily with a low speed/city profile, the gap may widen to as much as 20% or more. Software improvements have been made to the range algorithm to improve its accuracy in all driving scenarios. These updates are available with ISTA/P 3.55.0 (I-level I001-15-03-501). In addition, the following enhancements are integrated into this new I-level: ? The state of charge (SOC) percentage is visible in the upper left corner of the Kombi. It has been added to the board computer display in order for the customer to better manage the vehicle range. ? During vehicle charging with the doors locked, the charge port is also locked. However, now when charging commences, the charge port will be unlocked to allow for hospitality charging (charger sharing). ? REx only - if the SOC reaches 2.0% with the REx running, the message ""Low Battery. Power Reduction Possible."" will appear in the Kombi. In addition to the range display, the customer may notice that the vehicle's range has decreased as outside temperatures have gotten colder. This is most noticeable in extreme cold climates, and when preconditioning is not used. This situation does not indicate a problem and is independent of the range display algorithm.
