12V battery must be replaced - Schedule service
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.
Your vehicle is OK to drive with this alert present. However, if you delay the low voltage battery replacement, your vehicle may
eventually not have enough electrical power to start or to restart after a recent drive.
If the low voltage battery does not have enough electrical power to turn on your vehicle or open the doors, see Battery Care on
page 728 for recommended actions.
For more information on the battery system, see High Voltage Battery Information on page 728.
