Range Display Calibration
for Model 3
The range display in your vehicle is undergoing calibration. Until calibrated, displayed range may under or overestimate compared to distance driven. To improve accuracy, charge to 100% and wait until the charge port LED turns solid green, indicating a completed charging session. It is recommended for this configuration of vehicle to keep your charge limit set to 100%, even for daily use, and that you also fully charge to 100% at least once per week.
See the manual for more information on battery care and tips.
