WARNING: The high voltage system has no user serviceable parts. Do not disassemble, remove or replace high
voltage components, cables or connectors. High voltage cables are typically colored orange for easy
identification.
WARNING: Read and follow all instructions provided on the labels that are attached to Model S. These labels
are there for your safety.
WARNING: In the unlikely event that a fire occurs, immediately contact your local fire emergency responders.

your
Model S is available from Tesla.

About the High Voltage Battery
Model S has one of the most sophisticated battery
systems in the world. The most important way to preserve the high voltage Battery is to
LEAVE YOUR
VEHICLE PLUGGED IN when you are not using it. This is
particularly important if you are not planning to drive
Model S for several weeks.
NOTE: When left idle and unplugged, your vehicle
periodically uses energy from the Battery for system
tests and recharging the
low voltage battery when
necessary.
There is no advantage to waiting until the Battery

CAUTION: The Battery requires no owner
maintenance. Do not remove the coolant filler cap
and do not add fluid. If the instrument panel warns
you that the fluid level is low, contact Tesla
immediately.
CAUTION: Do not use the Battery as a stationary
power source. Doing so voids the warranty.

Opening the Charge Port
The charge port is located on the left side of Model S,
behind a door that is part of the rear tail light assembly.
Park
Model S to ensure that the charge cable easily
reaches the charge port.
With Model S in Park, press and release the button on
the Tesla charge cable to open the charge port door.
NOTE: If the charge cable is close to the charge port
door, you can press the button on the charge cable to
open the charge port door even when Model S is locked
or a recognized key is not within range.
You can also open the charge port door using any of these methods:

Charge Port Light

During Charging
During charging, the charge port light pulses green, and the
touchscreen displays real-time charging status. The
frequency at which the green charge port 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 charge port light does
not light up.
If the charge port light turns red while charging, a fault
is detected. Check the
instrument panel or touchscreen
for an alert 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: The thermal system may produce steam under
certain conditions. For example, odorless steam can come from the front of your vehicle while charging at a Supercharger in cold temperature. This is normal and not a cause for concern.
NOTE: It is normal to hear sounds during charging.
Particularly at high currents, the refrigerant compressor
and fan operate as needed to keep the Battery cool.
NOTE: Air conditioning performance is generally not
affected by charging. However, in some circumstances
(for example, charging at high currents during a
particularly warm day), the air coming from the vents may not be as cool as expected and a message displays on the
instrument panel. This is normal and ensures that
the Battery stays within an optimum temperature range while charging to support longevity and optimum
performance.
WARNING: Never spray liquid at a high velocity
(for example, a pressure washer) towards the
charge port while charging. Doing so can result in
serious injury or damage to the vehicle, charging
equipment, or property.
Stopping Charging
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, the charge cable latch remains locked and
Model S must be unlocked or able to recognize your key
before you can disconnect the charge cable.
To disconnect the charge cable:
1.
Press and hold the button on the connector handle to release the latch.
NOTE: You can also release the latch using the
touchscreen or mobile app, or by pressing and
holding the rear trunk button on the key fob.
If your
vehicle is equipped with a motorized charge port,
you can also press the button to the left of the
charge port to release the latch.
2.
Pull the connector from the charge port. The charge
port door automatically closes.
To disconnect the charge cable when using an adapter at a public charge station:
1.
Unlock Model S.
2.
While holding the public charging handle in one hand and the adapter in the other hand, press and hold the button on the public charging handle and pull both
outwards, removing the handle and adapter at the same time.
NOTE: If the charging station handle separates from
the adapter, leaving the adapter in
Model S, use the
touchscreen to unlock the charge port.
3.
Press and hold the button on the charging handle
again to release the adapter from the public charging handle.
NOTE: The charge port door automatically closes within
approximately 10 seconds of removing the connector from the charge port.
CAUTION: Tesla strongly recommends leaving
Model S plugged in when not in use. This maintains
the Battery at the optimum level of charge.
Charge Settings
Access charge settings by touching Controls > Charging
when Model S is in Park.
When charging, you can also touch the
charge icon on the touchscreen to access charge settings.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.
You can further adjust charge settings:
