Charging Instructions
1. Charge status messages (such as Charging, Charging Scheduled) display here.
2. Adjust the charge limit by touching Set Charge Limit, and drag the arrow to move the charge
limit setting. The setting you choose applies to immediate and scheduled charging sessions.
3. Set a recurring charging schedule for the location. When you set a scheduled charging time,
Model 3 displays the set time when you are parked at the scheduled location. If, at the
scheduled time, Model 3 is not plugged in at the location, charging starts as soon as you plug
it in, provided you plug it in within six hours of the scheduled time. If plugged in after six
hours, charging does not start until the scheduled time on the next day. To override this
setting, touch Start Charging or Stop Charging (see next item in this list).
4. Touch to open the charge port door or to start (or stop) charging.
5. 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 the up/down arrows
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 3 remembers the location. If you charge at
the same location, you do not need to change it again.
Note: If Model 3 is charging and detects unexpected fluctuations in input power, the charging
current is automatically reduced by 25%. For example, a 40 amp current is reduced to
30 amps. This automatic current reduction increases robustness and safety in situations when
an external problem exists (for example, a home wiring system, receptacle, adapter or cord is
unable to meet its rated current capacity). As a precaution, when Model 3 automatically
reduces current, it saves the reduced current at the charging location. Although you can
manually increase it, Tesla recommends charging at the lower current until the underlying
problem is resolved and the charging location can provide consistent power.
