Charging Instructions
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.
You can further adjust charge settings:
• Open Charge Port, Unlock Charge Port and Stop
Charging: When not charging, touch Open Charge
Port or Unlock Charge Port to open the charge port
door or to unlock the charge cable from the charge
port. Use Stop Charging when you are finished
charging.
• 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 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 S
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.
• Schedule: Depending on the setting you select by
touching Switch to Scheduled Departure/Scheduled
Charging, this displays either a departure time for
when the vehicle should be preconditioned and/or
charged by or a time to start charging (see
Scheduled Charging and Scheduled Departure on
page 160).
• Supercharging: Displays supercharger usage fees, the
location, the time that charging started, and a cost
estimate for the session (see
Fees and Idle Fees on page
NOTE: To reduce congestion at high-usage
supercharger sites, you may be limited to a maximum
charge of 80% when not using Trip Planner (see
Planner on page 128).

Trip
Scheduled Charging and Scheduled
Departure
Toggle between Scheduled Departure and Scheduled
Charging by touching Controls > Charging > Switch to
Scheduled Charging/Scheduled Departure when
Model S is in Park.
NOTE: Scheduled Charging/Scheduled Departure
settings are also available on the Climate Controls
screen and in the Tesla mobile app.
Think of Scheduled Charging as "When do I want
charging to start?" compared to Scheduled Departure
Off-Peak Charging which is "When do I want charging to
be complete?"
Scheduled Charging can be used together with
Scheduled Departure Preconditioning but not with
Scheduled Departure Off-Peak Charging.
Scheduled Charging/Scheduled Departure settings are
automatically saved for each location.
NOTE: If you plug in Model S with both Off-Peak
Charging and Scheduled Charging deselected, your
vehicle charges immediately.
Using Scheduled Charging
Use Scheduled Charging to specify a daily time in which
you want Model S to start charging.
With Scheduled Charging selected, enable the feature
then set a daily time to start charging.
NOTE: Scheduled Charging starts charging immediately
if Model S is plugged in up to 6 hours after the
scheduled start time. However, if Model S is plugged in
after six hours of the scheduled charging time, charging
may not start until the scheduled time on the next day.
Using Scheduled Departure
Use Scheduled Departure to set a daily time when you
want Model S to be ready to drive. Your vehicle
automatically calculates when it needs to start
preconditioning and/or charging. This ensures that
charging is complete and/or the cabin climate and
Battery are preconditioned by your departure time.
When Scheduled Departure is displayed, touch
Schedule to set a daily time when you want Model S to
be ready to drive. Specify a time, then touch Settings to
enable one or both of the following departure features.
When plugging in with Off-Peak Charging enabled, the
vehicle briefly draws power (you may hear clicking) to
calculate the necessary charging start time.
After you've specified your desired settings, touch Set.
The touchscreen displays your scheduled departure
time.
