(UMC_a008)
Unable to charge - Wall plug temperature high
Wall outlet and wiring inspection recommended
High temperature detected by Mobile Connector alerts indicate the outlet used to charge is
becoming too warm, so charging has stopped to protect the outlet.
This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. A warm outlet may be caused by a plug that is not fully inserted, a loose building
wiring connection to the outlet, or an outlet that is beginning to wear out.
To regain normal charge operation, make sure your adapter is fully plugged into the outlet. If
charging speed does not return to normal, contact an electrician to inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a
Tesla Wall Connector for greater convenience and highest charging speed.
(UMC_a017)
Charge rate reduced - Wall plug temperature high
Wall outlet and wiring inspection recommended
High temperature detected by Mobile Connector alerts indicate the outlet used to charge is becoming too warm, so charging has been slowed to protect the outlet.
This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. A warm outlet may be caused by a plug that is not fully inserted, a loose building
wiring connection to the outlet, or an outlet that is beginning to wear out.

Electrical system power reduced
Vehicle may shut down unexpectedly
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. It is also possible that your vehicle will not restart after the current drive.
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.
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.
If this alert remains active, it is recommended you schedule service immediately. Without
service, your vehicle may not drive, may shut down unexpectedly, or may not restart.

Electrical system backup power is unavailable
Vehicle will consume more energy while idle
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 Battery on page 177.
You may 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.
You may also notice that some nonessential features are not available. This is expected behavior
due to your vehicle preserving energy for essential functions.
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.
There is a chance that an issue affecting the primary power source could cause your vehicle to
shut down unexpectedly.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the electrical system can be restored.

Low voltage battery service is required
Schedule service - Vehicle may not restart
The low voltage battery cannot provide the electrical support necessary to drive or continue driving.
If this alert is present while you are driving, your vehicle needs to come to a stop as soon as
possible. Pull over safely at your earliest opportunity.
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.
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.

PULL OVER SAFELY
The electrical system cannot provide adequate support to drive or continue driving. Your vehicle
is preparing to shut down to preserve energy for essential functions other than driving.
