2023 TESLA MODEL 3 Owners Manual

UI_a013
Air pressure in tires very low
PULL OVER SAFELY - Check for flat tire
What this alert means:
This alert indicates that one or more of the tires on your vehicle is extremely low or flat.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is
significantly lower than the recommended cold tire pressure.
What to do:
You should pull over carefully as soon as possible. In a safe location, check for a flat tire.
You can request Tesla roadside assistance options (mobile tire, loaner wheel, tow) if required. See Contacting Tesla
Roadside Assistance on page 220 for more information.
In a non-emergency situation, it is recommended that you visit a local tire shop for assistance or schedule service
using your Tesla Mobile App.
See Maintaining Tire Pressures on page 176 for detailed information on where to find the recommended cold
pressure (RCP) for your vehicle

UMC_a002
Unable to charge - Mobile Connector GFCI tripped
Unplug charge handle from charge port and retry
What this alert means:
The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has
interrupted charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port,
or even an onboard vehicle component.
What to do:
Inspect the charge port and the charge handle for pooled water or unusual levels of moisture. If you find excessive
moisture, wait and let both the inside area of the charge port and the exposed portion of the charge handle dry
sufficiently before trying again.
Inspect the charge equipment for damage.

For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product

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 does not indicate an issue with your Mobile Connector or vehicle, but instead points to an issue with the wall
outlet / electrical installation the Mobile Connector is connected to.
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.
What to do:
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_a009
Cannot charge - Charge handle temperature high
Check charge handle or charge port for debris
What this alert means:
Charging has been interrupted because the Mobile Connector has detected a high temperature in the charge handle
that connects to your vehicle

After unplugging from the power source (wall outlet), inspect the wall plug adapter connection and the Mobile
Connector control box connection for any obstructions or moisture. Make sure any obstruction has been removed
and any moisture has been allowed to dry, then try re-inserting the wall plug adapter into the Mobile Connector and
then connecting to the power source (wall outlet).
Once the Mobile Connector control box temperature has decreased and any obstruction has been removed, the alert
should clear and charging should possible.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle

First, confirm the lack of effective communication is caused by the Mobile Connector rather than an issue with your
vehicle. This is usually the case.
To confirm this, try charging the vehicle using different external charging equipment.

UMC_a014
Wall plug adapter error - Charge rate reduced
Plug adapter fully into Mobile Connector and retry
What this alert means:
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot
identify the type of wall outlet the wall plug adapter is connected to, charge current is automatically reduced to 8A.
What to do:
1.
Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
2.
Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
a.
Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
b.
Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.
3.
Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
4.
If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully
connected to your Mobile Connector).
a.
If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b.
If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector. In the meantime, you can continue to charge with
the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition
persists.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle
