Air pressure in tires very low
PULL OVER SAFELY - Check for flat tire
What this alert means:

1032

Owner's Manual

Owners Manual
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 922 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 748Tire Pressures on page 1389 for detailed information on where to find the
recommended cold pressure (RCP) for your vehicle's tires, how to check tire pressures, and how to keep your tires properly
inflated.
The alert will clear once the TPMS has a consistent tire pressure measurement for each of your tires within 3 psi of the
recommended cold pressure.
• The alert and Tire Pressure indicator light may still be present immediately after you have filled your tires to the
recommended cold pressure, but both should clear once you have driven a short distance.
• You may need to drive over 15 mph (25 km/h) for at least 10 minutes for the Tire Pressure Monitoring System to measure
and report your updated tire pressures.

MCU_w010
Air pressure below recommendation for tires
Check pressure and refill air as needed
What this alert means:
This alert does NOT indicate that there is a flat tire.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is at least 20%
lower than the recommended cold tire pressure.
See Maintaining Tire Pressures on page 748Tire Pressures on page 1389 for detailed information on where to find the
recommended cold pressure (RCP) for your vehicle's tires, how to check tire pressures, and how to keep your tires properly
inflated.
This alert may appear in cold weather because the air in your tires naturally contracts when it becomes cold, decreasing tire
pressures.
What to do:
Add air to maintain the recommended cold tire pressure. Although drops in tire pressure are expected in colder weather, the
recommended cold tire pressure should be maintained at all times.
The alert may clear as the vehicle is driven. This is because the tires will warm up and the tire pressure will increase. Even if the
alert clears, the tires should still be refilled with air once they have cooled.
The alert will clear once the Tire Pressure Monitoring System detects that each of your tires is inflated to the recommended
cold pressure.
• The alert and Tire Pressure indicator light may still be present immediately after you have filled your tires to the
recommended cold pressure, but both should clear once you have driven a short distance.
• You may need to drive over 15 mph (25 km/h) for at least 10 minutes for the Tire Pressure Monitoring System to measure
and report your updated tire pressures.

Air conditioning temporarily reduced
Vehicle systems being cooled
What this alert means:

1034

Owner's Manual

Owners Manual
Cabin air conditioning performance has been temporarily reduced because your vehicle needs to focus on cooling the high
voltage battery (Battery) and/or powertrain. This is completely normal and does not indicate a problem with your vehicle or the
air conditioning (A/C) system.
In addition to cooling the vehicle interior, the A/C system also cools the Battery. The A/C system’s priority is to cool the
Battery to make sure it stays within an optimal temperature range that supports longevity and best performance.
In high temperature environments, it is normal for your vehicle to focus more for brief periods on cooling the Battery. When
this happens, it is most often because the vehicle is supercharging in hot weather.
What to do:
No action is required. Your vehicle is OK to drive.
The alert should clear in a short time, and cabin air conditioning performance should return to normal. In some cases, the alert
and vehicle behavior will continue until supercharging is complete.
If the alert persists over multiple drives and is accompanied by other alerts that indicate potential issues with the A/C system,
contact Tesla Service at your convenience to schedule an A/C system inspection.
THC_w0100
Battery heating unavailable - Charge rate reduced
Charging may be unavailable in cold temperatures
What this alert means:
A condition affecting the performance of your vehicle's high voltage battery heater has been detected.
Without adequate heating of the high voltage battery, charging speed (charge rate) may be reduced. Your vehicle may also be
unable to charge in cold ambient temperatures (cold weather) while high voltage battery heating remains unavailable.
What to do:
Your vehicle is OK to drive. Your vehicle is also OK to charge and connect to a charging station. However, your vehicle may be
unable to charge, or may charge more slowly than expected, in cold ambient temperatures.
If possible, try charging your vehicle in a closed environment like a garage, where warmer ambient temperatures may make
high voltage battery heating unnecessary.
If driving in cold ambient temperatures, it is recommended that you do NOT rely on charging stations along your route to reach
your destination, as the high voltage battery may be too cold to charge.
• If you need to charge, try to charge your vehicle immediately after a drive. The high voltage battery may still be warm from
the previous drive.
• Leaving your vehicle parked in cold ambient temperatures after a drive will cause the high voltage battery to cool, and
charging may become unavailable.
Similarly, it is recommended that you do not rely on regenerative braking to charge the high voltage battery while driving in
cold ambient temperatures, as regenerative braking may be unavailable if the battery temperature is too low. For more
information, see Regenerative Braking on page 461.
This alert may be present due to many conditions. It may be caused by a temporary condition that requires no action to
resolve.
However, if this alert persists over multiple drives, or is accompanied by other alerts indicating potential issues with your
vehicle's heating and/or air conditioning system, it is recommended that you schedule service at your earliest reasonable
opportunity.

Unable to charge with Mobile Connector
Inadequate outlet grounding - Try another outlet
What this alert means:
The Mobile Connector has detected that the electrical outlet has insufficient grounding, likely caused by an inadequate or
missing ground connection.
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.
What to do:
Have the electrical installation inspected by an electrician. Your electrician should make sure there is proper grounding at your
circuit breaker or power distribution box, and also make sure that appropriate connections are made to the outlet, before you
attempt to plug in the Mobile Connector again.
If you need to charge in the meantime, try charging using a different outlet, at another location, or with another type of
charging station.
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's touchscreen display. See Maps and Navigation on page 693 for more details.
For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's
manual.
UMC_w002
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.
• If the cable is in any way damaged or deteriorated, do not use it. Try different charging equipment instead.
• If the cable is in good condition, try charging again with the same Mobile Connector.
If the issue persists and prevents charging, try charging with different charging equipment.
This alert is usually specific to external charging equipment and power sources and does not typically indicate an issue with
your vehicle that can be resolved by scheduling service.
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's touchscreen display. See Maps and Navigation on page 693 for more details.
For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's
manual.
