1.
Driving distance: Displays the total
estimated driving distance available.
2.
Set limit: Adjust the charge limit by
dragging the arrow below the battery to
indicate the level of charging you want.
The setting you choose applies to
immediate and scheduled charging
sessions.
NOTE: A portion of the battery image
may appear blue. This indicates that a
small portion of the energy stored in the
battery is not available because the
battery is cold. This is normal and no
reason for concern. When the battery warms up, the blue portion no longer displays.
3.
Stop charging: Touch to stop charging.
4.
Charge current at this location: The
current automatically sets to the
maximum current available from the
attached charge cable, unless it was previously reduced to a lower level. If
needed, touch
- or + to change the
current (for example, you may want to
reduce the current if you are concerned
about overloading a domestic wiring
circuit shared by other equipment). It is
not possible to set the charging current to
a level that exceeds the maximum
available from the attached charge cable.
When you change the current,
Model S remembers the location. If you charge at
the same location, you do not need to
change it again.
NOTE: If Model S is charging and detects
