2023 TESLA MODEL 3 battery

If Vehicle Has No Power
If Model 3 has no low voltage power, perform the
following steps to open the hood or jump start the
low
voltage battery.
1.
Open the hood. See Opening Hood with No Power on
page 20 for more information on opening the hood if
the vehicle does not have power.
2.
Jump start the low voltage battery (see Jump
Starting on page 225).
NOTE: Tow providers: See Running Out of Range on
page 224 for more information on transporting the
vehicle to a charging station and preparing the vehicle
to charge.
CAUTION: Because the windows automatically
lower slightly when you open or close a door,
always connect to an external, low voltage power
supply before opening a door if the vehicle has no
power to avoid breaking a window (see Jump
Starting on page 225).
Instructions for Transporters
223Roadside Assistance

NOTE: In the unlikely event your vehicle runs out of
range while driving, pull over when safe to do so and contact
Tesla Roadside Assistance on page 220 or your
preferred tow provider.
If Model 3 runs out of range, the low voltage battery is
no longer supported

The procedure for jump starting differs depending on
whether the low voltage battery is lead-acid or lithium- ion. To determine which battery your vehicle uses, touch
Controls > Software > Additional Vehicle Information.
Both procedures are provided in this section.
The following instructions assume you are using an external
low voltage power supply (such as a portable
jump starter). If jump starting
Model 3 using another
vehicle, refer to the vehicle manufacturer

For more information on the high voltage battery, see High Voltage Battery Information on page 156.
BMS_a067
High voltage battery performance limited
OK to drive - Schedule service soon
What this alert means:
Your vehicle has detected a condition internal to the high voltage battery that is limiting the battery

BMS_a069
Battery charge level low
Charge now
What this alert means:
Your vehicle has detected that the high voltage battery does not have enough energy remaining to support driving.
This alert is usually present because your vehicle

The electrical system cannot maintain the voltage required to support all vehicle features.
If this alert is present while you are driving, it is possible your vehicle will shut down unexpectedly.
If this alert is present when your vehicle is in Park or when it first wakes, it is possible your vehicle may not have
adequate electrical power to start driving. A separate vehicle alert may be present to indicate that condition.
What to do:
It is recommended that you eliminate or reduce your use of any non-essential features. This can help your vehicle
maintain adequate electrical power for essential functions.
If this alert remains active, schedule service immediately. Without service, your vehicle may shut down unexpectedly
or may not restart.
VCFRONT_a182
Schedule service to replace low voltage battery
Software will not update until battery is replaced
What this alert means:
The low voltage battery is showing degraded performance and needs to be replaced. Until the low voltage battery is
replaced, vehicle software updates will not complete.
What to do:
It is recommended that you have the low voltage battery replaced at your earliest convenient opportunity.
You can schedule service via your Tesla Mobile App, or with an independent service provider that offers low voltage
battery replacement for your vehicle. Please note that independent service provider options may vary, based on your
vehicle configuration and your location.
If the low voltage battery does not have enough electrical power to turn on your vehicle or open the doors, follow the instructions in
Jump Starting on page 225.
For more information on the battery system, see High Voltage Battery Information on page 156.
VCFRONT_a191
Electrical system power reduced
Vehicle shutting down
What this alert means:
The low voltage battery cannot provide the electrical support necessary to drive or continue driving. Your vehicle is shutting down to preserve energy for essential functions other than driving.
Your vehicle cannot be driven or continue driving while this condition continues.
What to do:
If this alert is present while you are driving, your vehicle needs to come to a stop immediately. It is recommended
that you:

It is recommended that you schedule service at your earliest opportunity. Without service, your vehicle will remain
unable to restart, and the electrical system will remain unable to support all features and functions.
Some or all of the powered doors and windows in your vehicle may lose electrical power. If this occurs, you can still
use the manual door releases to exit the vehicle if necessary. For more information, see Opening Doors from the
Interior on page 14.
VCFRONT_a220
Electrical system is unable to support all features
Schedule service
What this alert means:
The low voltage battery is not available and cannot provide electrical support for vehicle features.
It is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the
current drive.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
What to do:
It is recommended that you eliminate or reduce your use of any nonessential features. This can help your vehicle maintain adequate electrical power for essential functions other than driving, until it can be serviced.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle
may not drive, may shut down unexpectedly, or may not restart.
VCFRONT_a402
Electrical system backup power is unavailable
Vehicle will consume more energy while idle
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the
voltage required to support all vehicle features.
The primary source of electrical power, the high voltage battery system, will continue to support vehicle functions,
even when your vehicle is idle. For more information on the high voltage battery, see
About the High Voltage Battery
on page 156.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down
unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain
adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the
electrical system can be restored.
