Some 2017-2019 Bolt EV models may not have charged to a full charge level, as shown on the power indicator gauge on the instrument cluster, after a complete vehicle charge event. The top indicator bar on the charge gauge will not be illuminated.
The vehicle may not charge to full capacity based on the vehicle settings. These settings differ based on model year.
2017-2018 Models
If the vehicle is not charging to full capacity, check if the Hill Top Reserve setting is selected. Hill Top Reserve enables regenerative braking efficiency to be maximized when driving from a higher elevation immediately after charging. When this feature is turned on, charging will stop before the high voltage battery is fully charged, which allows space for energy from regenerative braking.
TIP: Regenerative power may be limited when the battery is near a full charge or cold. The regen battery icon in the power indicator gauge will appear gray when limited.
To check if the Hill Top Reserve setting is on, press the Energy button on the infotainment screen and then select Energy settings > Hill Top Reserve. (Fig. 6) Press the On/Off button to select or deselect the setting.

2019 Models
If the vehicle is not charging to full capacity, the Target Charge Level may be activated and set to a lower charge rate than 100%. With this setting, a reminder will be displayed on the instrument cluster indicating Target Charge Level Active.
The Target Charge Level allows the charging range to be set based on what is needed. For example, when charging at a public pay station and a full charge is not needed, the Target Charge Level can be set to only get as much range as needed.
To determine if the Target Charge Level is turned on, press the Energy button on the infotainment screen and then select Charging > Target Charge Level. Adjust the charge level to the desired level of charging capacity using the plus/minus buttons on the screen. (Fig. 7)
