Charging Instructions
During Charging
During charging, the charge port pulses green and charging status displays on the instrument
panel. The frequency at which the charge port's light pulses slows down as the charge level
approaches full. When charging is complete, the light stops pulsing and is solid green.
Note: If Model S is locked, the light around the charge port does not light up.
If the light around the charge port lights up red while charging, a fault is detected. Check the
instrument panel or touchscreen for a message describing the fault. A fault can occur due to
something as common as a power outage. If a power outage occurs, charging resumes
automatically when power is restored.
Note: When charging, particularly at high currents, the refrigerant compressor and the fan operate
as needed to keep the Battery cool. Therefore, it is normal to hear sounds during charging.
Stopping Charging
You can stop charging at any time by disconnecting the charge cable or touching Stop Charging
on the touchscreen.
Note: To prevent unauthorized unplugging of the charge cable, Model S must be unlocked or able
to recognize a key before you can disconnect the charge cable.
To disconnect the charge cable:
1. Press and hold the button on a Tesla connector to release the latch. You can also touch Stop
Charging on the charging screen (see
2. Pull the connector from the charge port.
3. Push the charge port door closed.
Note: If Model S is equipped with a motorized charge port door, it automatically closes when you
remove the charge cable.
Caution: Tesla strongly recommends leaving Model S plugged in when not in use. This
maintains the Battery at the optimum level of charge.
