Battery Information
About the Battery
Model 3 has one of the most sophisticated
battery systems in the world. The most
important way to preserve the 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 3 for several weeks. When plugged in,
Model 3 wakes up when needed to
automatically maintain a charge level that
maximizes the lifetime of the Battery.
Note: When left idle and unplugged, your
vehicle periodically uses energy from the Battery for system tests and recharging the
12V battery when necessary.
There is no advantage to waiting until the
Battery’s level is low before charging. In fact, the Battery performs best when charged
regularly.
Note: If the Model 3 Battery becomes
completely discharged in a situation in which
towing is required, the owner is responsible
for towing expenses. Discharge-related towing
expenses are not covered under the Roadside
Assistance policy.
The peak charging rate of the Battery may
decrease slightly after a large number of DC
Fast Charging sessions, such as those at
Superchargers. To ensure maximum driving
range and Battery safety, the Battery charge
rate is decreased when the Battery is too cold,
when the Battery’s charge is nearly full, and when the Battery conditions change with
usage and age. These changes in the condition of the Battery are driven by battery physics
and may increase the total Supercharging
duration by a few minutes over time.
Battery Care
Never allow the Battery to fully discharge.
Even when Model 3 is not being driven, its
Battery discharges very slowly to power the
onboard electronics. The Battery can
discharge at a rate of approximately 1% per day, though the discharge rate may vary
depending on environmental factors (such as
cold weather), vehicle configuration, and your
selected settings on the touchscreen.
Situations can arise in which you must leave
Model 3 unplugged for an extended period of time (for example, at an airport when
traveling). In these situations, keep the 1% in
mind to ensure that you leave the Battery with a sufficient charge level. For example, over a
two week period (14 days), the Battery may
discharge by approximately 14%.
Discharging the Battery to 0% may result in
damage to vehicle components. To protect
against a complete discharge, Model 3 enters
a low-power consumption mode when the
displayed charge level drops to approximately
0%. In this mode, the Battery stops supporting
the onboard electronics and auxiliary 12V
battery. Once this low-power consumption
mode is active, immediately plug in Model 3 to
prevent a jump-start and 12V battery
replacement.
Note: If the vehicle is unresponsive and will
not unlock, open, or charge, then the 12V
battery may have become discharged. In this
situation, contact Tesla.
Temperature Limits
For better long-term performance, avoid
exposing Model 3 to ambient temperatures
above 140

Parts and Accessories
Parts, Accessories, and
Modifications
Use only genuine Tesla parts and accessories.
Tesla performs rigorous testing on parts to
ensure their suitability, safety, and reliability.
Purchase these parts from Tesla, where they
are professionally installed and where you can receive expert advice about modifications to
Model 3. Accessories are available for
purchase from Tesla stores or online at www.tesla.com/shop .
Tesla is unable to assess parts manufactured
by other distributors and therefore accepts no
responsibility if you use non-Tesla parts onModel 3.
Warning: Installing non-approved parts
and accessories, or performing non- approved modifications, can affect the
performance of Model 3 and the safety of
its occupants. Any damage caused by
using or installing non-approved parts, or by performing non-approved
modifications, is not covered by the
warranty.Warning: Tesla does not accept liability
for death, personal injury or damage that
occurs if you use or install non-approved
accessories or make non-approved
modifications.Body Repairs
If Model 3 is in a collision, contact Tesla toensure that it is repaired with genuine Tesla
parts. Tesla has selected and approved body
shops that meet strict requirements for
training, equipment, quality, and customer
satisfaction.
Some repair shops and insurance companies
might suggest using non-original equipment
or salvaged parts to save money. However,
these parts do not meet Tesla

eCall
eCall
Model 3 is equipped with eCall, an emergency
call system that automatically contacts
emergency responders and communicates eCall standardized information to a PublicSafety Answering Point (PSAP) in the event of
a serious accident or emergency.
Note: Information communicated to PSAP
includes vehicle type, number of passengers
detected in the vehicle, GPS, and the VIN.
Note: eCall only operates over a cellular
network with an adequate signal.
Using eCall
eCall activates automatically if airbags deploy or a severe collision is detected. You can also
activate it manually by pressing the SOS
button on the overhead console.
Note: Manual activation is useful to report a
serious accident or to call for help if an
occupant in Model 3 requires immediate
attention (such as a heart attack).
Canceling eCall
eCall can only be canceled when it is manually
activated. To cancel eCall, press
