Camera blocked or blinded
Clean camera or wait for it to regain visibility
What this alert means:

300

Owners Manual
One or more of the vehicle cameras has limited visibility, or no visibility at all, due to external conditions. When the
cameras on your vehicle cannot provide accurate visual information, some or all Autopilot features may be
temporarily unavailable.
Cameras may have limited or no visibility due to:
• Dirt or debris on the camera surface.
• Environmental conditions like rain, fog, snow, or dew.
• Bright sunlight or glare from another light source.
• Low or limited light conditions, including unlit or poorly lit roadways at night.
• Condensation (water droplets or mist) on the camera surface.
• Monotonous environmental features, including tunnel walls or highway dividers.
What to do:
Continue to your destination. Your vehicle is OK to drive. This is often a temporary issue that will be resolved when
condensation evaporates, or when a particular environmental condition or feature is no longer present.
If the alert does not clear by the time you reach your destination, check camera surfaces for condensation, dirt, or
other debris. For camera locations, see Cameras on page 25.
Clean the cameras as necessary before your next planned drive. For recommended cleaning procedures, see
Cleaning a Camera on page 254.
If you continue to see this alert after cleaning the cameras, check the inside surfaces of the door pillar camera
enclosures for condensation. Although condensation inside the camera enclosures cannot be wiped clean, you can
usually clear it faster by following these steps:
1. Precondition the cabin by turning Climate ON, setting temperature to High, and making sure A/C is ON.
2. Turn on the front windshield defroster.
3. Direct the air vents toward the door pillar cameras.
For more information on clearing condensation from camera enclosures, see Cleaning a Camera on page 254.
If the alert does not clear by the end of your next planned drive, despite cleaning the indicated camera(s) and
following recommended steps to clear condensation, schedule service at your next convenient opportunity. Your
vehicle is OK to drive in the meantime.

Vehicle shutting down - PULL OVER SAFELY
Battery charge level too low
What this alert means:
Your vehicle has detected that the high voltage battery does not have enough energy remaining to support driving.
Your vehicle will be unable to drive or continue driving until charged.
If this alert is present while you are driving, your vehicle needs to shut down. A separate vehicle alert should be
present to indicate this condition. It is also possible your vehicle may shut down unexpectedly.
If this alert is present when your vehicle is parked, you may be unable to drive.
This alert is usually present because your vehicle's high voltage battery charge level has been reduced through
normal operation.
What to do:
Charge your vehicle immediately. Charging your vehicle should restore your vehicle's ability to drive.

301

Owners Manual
If this alert occurs during subsequent drives, despite a displayed battery charge level of 5% or higher, schedule
service at your earliest convenience.
For more information on the high voltage battery, see High Voltage Battery Information on page 224.
For more information on charging, see Charging Instructions on page 226.

Maximum battery charge level reduced
OK to drive - Schedule service
What this alert means:
Your vehicle has detected a condition internal to the high voltage battery that is limiting the battery’s performance.
As a result, maximum charge level and range are reduced. Service is required to restore full performance.
What to do:
If this alert persists, schedule service soon. Without service, your vehicle's maximum charge level and range will
remain limited.
Your vehicle is OK to drive and charge.
For more information on the high voltage battery, see High Voltage Battery Information on page 224.

Charging adapter has electric arc flash hazard
Use different charging equipment
What this alert means:
Charging is unavailable because your vehicle has detected an electric arc flash hazard in the third-party charging
adapter used to connect a Combined Charging System (CCS) charge handle to your vehicle’s charge port.
An electric arc flash can occur if you attempt to unplug while actively charging with the third-party charging
adapter, and an electric arc flash can cause serious bodily injury and/or property damage.
What to do:
Follow the steps below to mitigate this risk:
• Make sure charging is completely stopped.
1. Use your vehicle touchscreen to confirm charging has stopped, or to stop charging if necessary.
2. Use the charging station display and controls to confirm charging has stopped, or to end any active charging
session.
• Make sure no flashing green or blue light (LED) is visible on your vehicle’s charge port.
• Unplug the charging adapter from your vehicle’s charge port.
• Confirm again that the charging station indicates no active charging session.
• Unplug the charging adapter from the charge handle.
Use different charging equipment to charge your vehicle. For more information on charging, see Charging
Instructions on page 226.
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 209 for more
details.

Charging equipment communication error
Try again or try different equipment
What this alert means:

313

Owners Manual
Your vehicle is unable to charge because it cannot communicate effectively with the external charging equipment. It
cannot sense a valid control pilot signal coming from the 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.
What to do:
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, such as debris, moisture, and/or foreign objects. Make sure any charge port inlet obstruction has been
removed and any moisture has been allowed to dry, then try re-inserting the cable into the charge port.
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 209 for more
details.
