Some Tesla owners have reported that the cabin overheat protection setting is greyed out and cannot be enabled or disabled.
This means that the feature is either stuck in its current state (on or off) or not working at all.
In this article, we will explore the possible causes and solutions for this problem, and help you keep your Tesla cool and comfortable.
How to fix the Tesla Cabin Overheat Protection Greyed Out Issue?
If COP is not working properly, owners should try the following solutions:
#1. Check battery level
Owners should check their Tesla battery levels and charge them if needed. COP will not work if the battery level is below 20%.
#2. Turn off Sentry mode
Owners should turn off Sentry mode if they want to use COP. Sentry mode can drain the battery and increase the heat inside the car.
Owners can turn off Sentry mode from the vehicle touchscreen or the Tesla app.
#3. Delete user profiles
Owners should delete some or all of their user profiles if they suspect that they are causing problems with COP.
Owners can delete user profiles from the vehicle touchscreen or the Tesla app.
#4. Update software
Owners should update their software if there is a new version available. Software updates can fix bugs and improve features, including COP.
Owners can update their software from the vehicle touchscreen or the Tesla app.
#5. Check the climate settings
You can access the climate settings from the touchscreen or the Tesla app. Make sure that COP is enabled and set to either No A/C or A/C On.
If you choose No A/C, COP will use only the fan to cool down the cabin.
If you choose A/C On, COP will use both the fan and the air conditioning to cool down the cabin. The latter option is more effective, but it also consumes more battery power.
#6. Check the cabin temperature
You can check the cabin temperature from the Tesla app. If the cabin temperature is below 105°F, COP will not activate, as it is designed to prevent extreme heat only.
If the cabin temperature is above 105°F, COP should activate automatically, unless there is another issue preventing it from working.
#7. Check the external temperature
COP may not work properly if the external temperature is too high or too low.
According to Tesla, COP works best when the external temperature is between 50°F and 105°F.
If the external temperature is outside this range, COP may not be able to cool down or heat up the cabin effectively.
#8. Check the sun exposure
COP may not work properly if the car is exposed to direct sunlight for a long time.
Sunlight can increase the heat inside the car and make it harder for COP to cool it down.
To avoid this, try to park your car in a shaded area or use a sunshade to block some of the sunlight.
#9. Check the windows and doors
COP may not work properly if the windows or doors are open or cracked.
This can allow hot air to enter or cold air to escape from the cabin, affecting the temperature and pressure inside.
To avoid this, make sure that all windows and doors are closed and locked before leaving your car.
Why is Tesla Cabin Overheat Protection Greyed Out?
#1. Low battery level
COP requires at least 20% of the battery charge to operate. If the battery level falls below this limit, COP will turn off to save energy.
Owners should ensure that their cars have enough battery before leaving them in hot places.
#2. Sentry mode conflict
Sentry mode is a security feature that monitors the surroundings of the car and alerts the owner of any potential threats.
However, Sentry mode also uses a lot of battery power and generates heat inside the car.
In older Tesla models (Model S, Model X, and Model Y), Sentry mode and COP cannot run at the same time, so owners have to choose one or the other.
In newer Tesla models (Model 3 and Model Y), Sentry mode and COP can work together, but only if COP is set to use air conditioning and not just the fan.
#3. User profile glitch
User profiles are a way of customizing the settings and preferences of different drivers or passengers.
Some owners have found that having multiple user profiles can interfere with COP, and deleting some or all of them can restore COP functionality.
This could be due to a software bug or glitch that confuses the system about which profile’s settings to follow.
#4. Software update issue
Software updates are meant to improve the performance and features of Tesla vehicles, but sometimes they can also introduce new problems or bugs.
Some owners have reported that COP stopped working after installing a software update, and they had to wait for another update or contact Tesla service to fix it.
Owners should always check if their software is up to date and report any issues to Tesla as soon as possible.
#5. The car is not in Park mode
The cabin overheat protection can only be turned on or off when the car is parked and not moving.
If the car is in Drive, Reverse, or Neutral mode, the setting will be greyed out.
This is because the feature is designed to work only when the car is stationary and not in use.
To fix this, make sure the car is in Park mode and then try to access the setting again.
#6. The battery level is too low
The cabin overheat protection will not activate if the battery charge drops below 20%, and it will automatically turn off if it reaches that level while it is on.
This is to prevent excessive battery drain and preserve range. If the battery level is below 20%, the setting will be greyed out.
This is because the feature requires a minimum amount of battery power to operate.
To fix this, make sure the battery level is above 20% and then try to access the setting again.
#7. The car is in transport mode
Transport mode is a setting that Tesla uses to ship its vehicles from the factory to the delivery centers.
It disables some features that consume battery power, such as cabin overheat protection, sentry mode, and climate control.
Transport mode should be turned off by Tesla before delivering the car to the customer, but sometimes it might not happen due to human error or software glitches.
If the car is in transport mode, the setting will be greyed out. This is because transport mode overrides all other settings and puts the car in a low-power state.
To fix this, contact Tesla support or the service center and ask them to turn off transport mode remotely or manually.
#8. The car is in Dog Mode or Camp Mode
These modes are designed to keep the cabin comfortable for occupants or pets when the car is parked.
They override the cabin overheat protection setting and keep the climate control on until the battery reaches 20%.
If the car is in Dog Mode or Camp Mode, the cabin overheat protection will be greyed out.
This is because these modes have their own temperature settings and do not need the cabin overheat protection feature.
To fix this, exit these modes by touching the X icon on the touchscreen or by unlocking the car with the key fob or app.
#9. The car is in Sentry Mode
Sentry Mode is a security feature that monitors the surroundings of the car when it is parked and alerts the owner of any potential threats.
It also consumes battery power and may interfere with the cabin overheat protection setting.
If the car is in Sentry Mode, the cabin overheat protection will be greyed out.
This is because Sentry Mode prioritizes security over comfort and may prevent the air conditioning system from running.
To fix this, turn off Sentry Mode by touching Controls > Safety & Security > Sentry Mode on the touchscreen or by using the app.
#10. The car has a faulty sensor or fuse
The cabin overheat protection relies on sensors and fuses to detect and regulate the cabin temperature.
If any of these components are damaged or malfunctioning, the feature may not work properly or at all.
If the car has a faulty sensor or fuse, the cabin overheat protection may be greyed out or ineffective.
This is because the car cannot measure or control the cabin temperature accurately. To fix this, contact Tesla service and have them inspect and replace the faulty parts.
