This is often a temporary issue that will clear up when condensation evaporates or a particular environmental
condition is no longer present.
If the alert does not clear by the end of your drive, inspect and clean the front camera area at the top center of the
windshield before your next planned drive. Check the camera surface for condensation, dirt, or other debris and
attempt to clear any obstruction. See the
About Autopilot on page 78 sections “How It Works” and “Cleaning
Cameras and Sensors” for more on front camera location and tips for careful cleaning.
Although condensation on the inside of the front camera enclosure cannot be wiped clean, you can usually clear it
quicker by following these steps:
1.
Pre-condition the cabin with the temperature set to High and A/C turned ON.
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.

Cruise control unavailable
Continue 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.
For your convenience, a calibration progress indicator is displayed on the touchscreen. 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 on page 79 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,
schedule service at your earliest convenience. Your vehicle is OK to drive in the meantime.

Camera blocked or blinded
Clean 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:
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.
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 About Autopilot on page 78.
Clean the cameras as necessary before your next planned drive. For recommended cleaning procedures, see
Cleaning Cameras and Sensors on page 80.
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.
Pre-condition the cabin with the temperature set to High and A/C turned 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 Cameras and Sensors on page
80.
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.

Unable to charge - Incorrect switch setting
Wall Connector rotary switch must be adjusted
What this alert means:
Incorrect rotary switch setting.
What to do:
Make sure there is no power to the Wall Connector. Remove the face plate and adjust the rotary switch to a valid
operating current setting. The correlation between switch setting and current is printed on the inside of the Wall
Connector. You can also refer to the Set the Operating Current section in the Wall Connector Installation Manual. If
the Wall Connector is set up for load sharing (paired with other Wall Connectors), the rotary switch of the master
unit must be set to an operating current setting that allows each paired Wall Connector to receive at least 6A of
charge current. Example: Three Wall Connectors are paired for load sharing. The master unit needs to be set to a
current of at least 3 * 6A = 18A or greater.

12V battery must be replaced - Schedule service
Software will not update until battery is replaced
The 12V battery is showing degraded performance and needs to be replaced. Until the 12V battery is replaced,
vehicle software updates will not complete.
It is recommended that you have the 12V battery replaced at your earliest convenient opportunity.
You can schedule service via the Tesla Mobile App, or with an independent service provider that offers 12V battery
replacement for your vehicle. Please note that independent service provider options may vary, based on your vehicle
configuration and your location.
Your vehicle is OK to drive with this alert present. However, if you delay the 12V battery replacement, your vehicle
may eventually not have enough power to start or to restart after a recent drive.
If the 12V battery is too low to turn on the vehicle or open the doors, follow the instructions in Jump Starting the 12V
