Battery Charging or Jump Starting
WARNING: This page is about a different car, the 2023 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
To charge or jump start the vehicle, connect the positive cable to the battery positive post. It is preferred to connect the negative cable to a vehicle ground and not the battery negative post. Connecting directly to the negative battery post can have an adverse effect on the Electrical Energy Management system. For a good connection point, follow the cable from the battery negative post to the vehicle body connection (typically on the shock tower sheet metal) and connect there. Often there is a stud in that location.
If the battery is jump started or charged, the BCM must recalibrate the battery state of charge. Engine off load shedding may occur if the vehicle is operated before the BCM calibrates the new battery state of charge.
NOTE:
DO NOT reset the battery monitoring system using the diagnostic scan tool. This reset is reserved for new battery installation. Resetting the battery monitoring system will clear the learned battery data, the battery time in service, and will affect the aging algorithm parameters, which have been learned since the installation of the battery.
