Tesla Model 3: Cabin Air Filter

Model 3 has an air filter that prevents pollen, industrial fallout, road dust and other particles from entering through the vents. Tesla recommends replacing the cabin air filter every 2 years.

Cabin Overheat Protection

The climate control system can reduce the temperature of the cabin in extremely hot ambient conditions for a period of up to twelve hours after you exit Model 3. Touch Controls > Safety & Security > Cabin Overheat Protection and choose:

  • OFF: Disable Cabin Overheat Protection.
  • NO A/C: Only the fan operates when the cabin temperature exceeds 105Вє F (40Вє C).

    This option consumes less energy but the cabin temperature may exceed 105Вє F (40Вє C).

  • ON: The air conditioning operates when the cabin temperature exceeds 105Вє F (40Вє C).

Note: Cabin Overheat Protection operates only when the energy remaining in the Battery is above 20%.

Warning: Never leave children or pets in the vehicle unattended. Due to automatic shut-off or extreme outside conditions, the inside of the vehicle can become dangerously hot, even when Cabin Overheat Protection is enabled.

Climate Control Operating Tips

  • You can direct the face-level vents toward the windows to help defrost or defog them.
  • When you use the mobile app to turn on the climate control system, it automatically turns off after four hours or if the charge level drops to 20%. To cool or heat the cabin for a longer period, you must turn it on again.
  • Your charge port latch may freeze in extremely cold weather or icy conditions.

    In cases where you cannot remove or insert the charge cable, or the car is not Supercharging due to the latch being frozen in place, use your Tesla mobile app to precondition your vehicle on HI for approximately 30-45 minutes (you must use your mobile app to precondition the vehicle; setting your climate to HI using the touchscreen is not effective). This helps thaw ice on the charge port latch so the charge cable can be removed or inserted.

  • If the climate control system is louder than you prefer, manually reduce the fan speed.
  • In addition to cooling the interior, the air conditioning compressor also cools the Battery. Therefore, in hot weather, the air conditioning compressor can turn on even if you turned it off. This is normal because the system's priority is to cool the Battery to ensure it stays within an optimum temperature range to support longevity and optimum performance.
  • Even when not in use, you may hear Model 3 emit a whining noise or the sound of water circulating. These sounds are normal and occur when the internal cooling systems turn on to support various vehicle functions, such as maintaining the 12V battery and balancing the temperature of the high voltage Battery.
  • To ensure the climate control system operates efficiently, close all windows and ensure that the exterior grill in front of the windshield is free of ice, snow, leaves, and other debris.
  • In very humid conditions, it is normal for the windshield to fog slightly when you first turn on the air conditioning.
  • It is normal for a small pool of water to form under Model 3 when parked. Extra water produced by the dehumidifying process is drained underneath.
  • To reduce the temperature in the cabin in hot weather conditions, the fan may turn on to vent the cabin when the vehicle is parked. This occurs only if the battery's charge level is above 20%.
