Troubleshooting Alerts

(APP_w207)Autosteer temporarily unavailable

Autosteer is currently unavailable. This could be a temporary condition due to external conditions that include:
  • Missing or faded lane markers
  • Narrow or winding roads
  • Poor visibility due to rain, snow, fog, or other weather conditions
  • Extremely hot or cold temperatures
  • Bright light due to other vehicle headlights, direct sunlight, or other light sources

If the alert is caused by a temporary factor like these, no action or service is typically needed. Continue to your destination. The alert will clear and Autosteer will be available once the condition is no longer present.

Please note that the minimum speed to initiate Autosteer when there is no vehicle detected ahead of you and while driving on a road with visible lane markings is 18 mph (30 km/h), unless certain vehicle and environmental conditions are met. If a vehicle is detected ahead of you:
  • You can initiate Autosteer at any speed under 90 mph (150 km/h).
  • You can even initiate Autosteer when stationary, provided the other vehicle is at least 5 feet (150 cm) in front of you.

This alert will be present if you have temporarily exceeded 90 mph (150 km/h) with Autosteer active, and Autosteer will not be available for the rest of your current drive.

Informational PurposesAn informational icon, calling your attention
Note
If this alert becomes active while you are driving in Germany, Autosteer should again be available once your vehicle is traveling below 90 mph (150 km/h).
If Autosteer is not available by the time you reach your destination, and remains unavailable during your next planned drive, the problem might be one of these issues:
  • Damage or obstruction caused by mud, ice, snow, or other environmental factors
  • Obstruction caused by an object mounted on the vehicle, like a bike rack
  • Obstructions caused by adding paint or adhesive products like wraps, stickers, or rubber coatings to your vehicle
  • A damaged or misaligned bumper

The solution might be as simple as washing your vehicle. If you do not find any obvious obstructions or you find damage to the vehicle, schedule service at your convenience. Your vehicle is OK to drive in the meantime.

For more information, see Autosteer.

  2. Turn on the front windshield defroster.

Once all front cameras regain adequate visibility, the alert will clear and both Traffic-Aware Cruise Control and Autosteer should again be available.

If this alert persists throughout subsequent drives but no front camera obstruction is visible, schedule service at your earliest convenience. Your vehicle is OK to drive in the meantime.

(APP_w224)Cruise control unavailableContinue driving to allow cameras to calibrate

Traffic-Aware Cruise Control and Autosteer are unavailable because the cameras on your vehicle are not fully calibrated. Continue to your destination. Your vehicle is OK to drive.

Traffic-Aware Cruise Control and Autosteer will remain unavailable until camera calibration is complete.

Your vehicle must maneuver with great precision when features like Traffic-Aware Cruise Control and Autosteer are active. Before these features can be used for the first time, the cameras must complete an initial self-calibration. Occasionally, one or more cameras can become uncalibrated.

Calibration typically completes after your vehicle has driven 20-25 miles (32-40 km), but the distance varies depending on road and environmental conditions. For example, driving on a straight road with highly visible lane markings helps the cameras calibrate quicker.

See Drive to Calibrate Cameras for more information.

When calibration is complete, Traffic-Aware Cruise Control and Autosteer should be available.

If the alert persists and camera calibration has not completed after your vehicle has driven 100 miles (160 km) or more, or Traffic-Aware Cruise Control and Autosteer remain unavailable despite successful camera calibration, contact Tesla Service at your earliest convenience. Your vehicle is OK to drive in the meantime.

(APP_w304)Camera blocked or blindedClean camera or wait for it to regain visibility

One or more of the vehicle cameras is blocked or blinded due to external conditions. When the cameras cannot provide accurate visual information, some or all Autopilot features may be temporarily unavailable.

Cameras can be blocked or blinded due to many factors, including:
  • Dirt or debris on the camera surface
  • Environmental conditions like rain, fog, snow, or dew
  • Bright sunlight or glare from another light source
  • Condensation (water droplets or mist) on the camera surface

Continue to your destination. Your vehicle is OK to drive.

This is often a temporary issue that will be resolved when condensation evaporates or a particular environmental condition is no longer present.

First, confirm the lack of effective communication is caused by the external charging equipment rather than an issue with your vehicle. This is usually the case.

Try charging the vehicle using different external charging equipment (including charge cable, charging station, or charging stall).

  • If the vehicle begins charging, the issue was likely with the equipment.
  • If the vehicle still does not charge, the issue may be with the vehicle.

If the issue is suspected to be with the vehicle, inspect the charge port inlet and the charge cable connector for any obstructions (use a flashlight as necessary). Debris, moisture, and/or foreign objects present in the charge port inlet or the charge cable connector can prevent the charge port from properly communicating with the charging equipment.

It is recommended that any debris / foreign objects be removed and any moisture be allowed to dry. Afterward, try re-inserting the cable into the charge port. Charging should now be possible.

As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:
  • Try charging with multiple, different types of charging equipment.
  • Make sure any charge port inlet obstruction has been removed.

    • Regenerative braking is reduced when the battery is at 95% charge or higher.
  • High voltage battery is cold:
    • The battery may not be warm enough for full regenerative braking performance.
    • This can happen at the beginning of a drive. It may happen frequently in colder climates.

Driving your vehicle will usually clear this alert, because it should reduce the battery charge below 95% and/or sufficiently heat the battery.

Informational PurposesAn informational icon, calling your attention
Note
In colder climates, this alert may remain present indefinitely and automatic deceleration may remain limited, as driving your vehicle may not heat the battery enough to restore full regenerative braking performance. This alert, by itself, does not typically indicate a condition requiring service.

For more information, see Regenerative Braking.

For more information on the battery system, see High Voltage Battery Information.

(GTW_w360)Assist for low brake performance activatedTo stop, keep brake pedal firmly pressed

Hydraulic Fade Compensation is active. This brake assist function activates temporarily to make sure you have full braking capability in conditions where reduced braking performance is detected by your vehicle.

Continue to press the brake pedal as you normally would, and do not "pump" (repeatedly press and release) the pedal as this will interrupt the function.

This alert will clear when your vehicle comes to a stop or you are no longer pressing the brake pedal. It may still be displayed for up to 5 seconds afterward.

When this assist function activates, you may feel the brake pedal pull away from your foot and notice a strong increase in brake pressure. You may also hear a pumping sound coming from the brake hydraulic unit at the front of the vehicle. This will usually last for a few seconds, depending on road surface and vehicle speed. This is completely normal and does not indicate any issue with your vehicle.

Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake temperatures after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your brake pads or rotors have worn to the point that normal replacement is needed.

If you continue to experience reduced braking performance which does not improve over time, please contact Tesla service at your convenience for a brake inspection.

For more information, see Hydraulic Fade Compensation.

(GTW_w405)Electrical system power reducedVehicle may shut down unexpectedly

The electrical system cannot maintain the voltage required to support all vehicle features.

(MCU_w008)Air pressure in tires very lowPULL OVER SAFELY - Check for flat tire

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.

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 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 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.

For more information on tire pressure, inflation, and maintenance, see Tire Care and Maintenance.

(MCU_w010)Air pressure below recommendation for tiresCheck pressure and refill air as needed

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 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.
  • Although drops in tire pressure are expected in colder weather, air should still be added to maintain the recommended cold tire pressure.
  • 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. For the best experience with your vehicle, the recommended cold tire pressure should be maintained at all times.
The alert should 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.

If you repeatedly see this alert for the same tire, have the tire inspected for a slow leak. You can visit a local tire shop or schedule service using your Tesla Mobile App.

For more information on tire pressure and inflation, see Tire Care and Maintenance.

(MCU_w029)Service is requiredSchedule service now

This alert is set remotely by Tesla when a condition requiring service is detected on your vehicle.

This alert can be set due to various conditions. When you schedule service, more information should be available.

This alert can only be cleared by a service technician after your vehicle has been serviced.

As this alert can be present due to various conditions, it is recommended that you schedule service at your earliest convenience.

(THC_u0005)Air conditioning temporarily reducedVehicle systems being cooled

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.

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.

(UMC_w002)Unable to charge - Mobile Connector GFCI trippedDisconnect and retry or use different equipment

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.

Inspect the charge port as well as 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.

As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:

  • Try charging with multiple, different types of charging equipment.

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 for more details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's manual.

(UMC_w004)Unable to charge with Mobile ConnectorVoltage too high / Try a different wall outlet
