Climate Controls

Overview of Climate Controls

Climate controls are always available at the bottom of the touchscreen. To turn the climate control system on, touch the fan icon or adjust the cabin temperature. To turn it off, touch the fan icon and then touch the off button near the center of the popup window.

By default, climate control is set to the Auto setting, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the cabin temperature in the Auto setting, the system automatically adjusts the heating, air conditioning, air distribution, and fan speed to maintain the cabin at your selected temperature. To override the Auto setting, touch the fan icon, turn off the Auto setting, then manually adjust your settings (see Adjusting Climate Control Settings). If you've manually adjusted individual settings, you can also revert back to Auto at any time by touching AUTO on the climate control popup window.

Note

The following illustration is provided for demonstration purposes only. Depending on vehicle options, software version, market region, and settings, the information displayed may be slightly different.

1. Seat heaters operate at three setting levels from 3 (highest) to 1 (lowest). When operating, the associated seat icon displays twisting lines that turn red to indicate the setting level. If equipped with the premium package, rear seats are also equipped with seat heaters (see Operating Seat Heaters).
2. Touch an up or down arrow to change the cabin temperature. To apply a temperature setting to both the driver and passenger side, touch SYNC on the popup that appears when you touch an arrow. When you apply the same temperature to both sides, only one temperature setting displays. Touch SYNC again to display separate temperature settings for the driver and passenger.
3. Touch the fan icon to turn on climate control and to manually customize settings to suit your preferences (see Adjusting Climate Control Settings). Touch and hold the fan icon to quickly turn off climate control. If your vehicle is equipped with the premium package, touch this icon to access controls for the rear seat heaters.
4. The windshield defroster distributes air flow to the windshield. Touch once to defog the windshield (the icon turns yellow). Touch a second time to defrost the windshield (the icon turns red and the heating and fan operate at maximum levels). Touch a third time to turn off and restore the air distribution, heating, and fan to their previous settings. In cold ambient temperatures, the exterior side mirrors are also heated whenever the windshield defroster is operating. See Cold Weather Best Practices for more information on preparing for cold weather.
5. Touch to warm up the rear window. When operating, the icon turns red. After 15 minutes, the rear window defroster automatically turns off. The exterior side mirrors are also heated whenever the rear window defroster is operating.

Warning

To avoid burns resulting from prolonged use, individuals who have peripheral neuropathy, or whose capacity to feel pain is limited because of diabetes, age, neurological injury, or some other condition, should exercise caution when using the climate control system and seat heaters.

Note

The climate control system is powered by the high voltage battery. Therefore, prolonged use decreases driving range.

Adjusting Climate Control Settings

To override the Auto setting, touch the fan icon, turn off the Auto setting, then use the buttons that appear to manually adjust settings.

1. Touch to turn the climate control system off.
2. The fan icon represents the general settings tab and displays by default. Touch the seat heater icon to access controls for the front and rear seat heaters (see Operating Seat Heaters).
3. Choose where air flows into the cabin (windshield, face-level, or foot-level vents). You can choose more than one location.

   Note

   When air is directed to the foot-level vents, air continues to flow to the windshield vents to assist in defogging. When air is directed to the face-level vents, air does not flow to the windshield.

4. Touch to adjust how air flows from the driver's vent. See Adjusting the Front Vents.
5. Touch to turn air flow to the rear cabin area on or off. When on, air flows from the vents located at the back of the center console. See Adjusting the Rear Vents.
6. Touch to adjust how air flows from the front passenger vent. See Adjusting the Front Vents.
7. When Model 3 is in Park, these settings display to allow you to keep the climate control system operating even if you leave your vehicle (see Keep Climate On, Dog Mode, and Camp Mode).
8. Touch to turn the air conditioning system on or off. Turning it off reduces cooling, but saves energy.

   Note

   Because Model 3 runs much quieter than a gasoline-powered vehicle, you may notice the sound of the air conditioning compressor as it is operating. To minimize noise, reduce the fan speed.

9. Touch + or - to increase or decrease the fan speed.

   Note

   Adjusting the fan speed may change the selected setting for how air is drawn into Model 3 in order to increase or reduce air flow.

10. Touch to control the flow of air inside the cabin. Air can be drawn into Model 3 from outside or air can be recirculated inside the cabin.
11. When Model 3 is in Park, touch SCHEDULE to set a recurring daily time when you want Model 3 to be ready to drive by preconditioning the Battery and cabin climate and/or charging during off-peak hours (see Scheduled Charging and Scheduled Departure).
12. Touch AUTO to turn the Auto setting on or off.

Operating Seat Heaters

To control the front seat heaters for the driver and passenger, touch the corresponding control on the main climate control area at the bottom of the touchscreen. To control the rear seat heaters (if equipped) or access duplicate controls for the front seat heaters, touch the fan icon, then touch the seat heater icon followed by the seat for which you want to adjust heating. Seat heaters operate at three setting levels from 3 (highest) to 1 (lowest). When operating, the associated seat icon displays twisting lines that turn red to indicate the setting level. You can touch All Off to turn off all seat heaters simultaneously.

Adjusting the Front Vents

Model 3 has a unique horizontal face-level vent that spans the width of the dashboard. Using the touchscreen, you can pinpoint exactly where you want to direct the air flowing from this vent when heating or cooling the front cabin area.

1. Driver vent and controls
2. Passenger vent and controls

When the face-level vent is on you can adjust the direction of the air flow from each vent. To adjust the direction of the air flow, simply touch the radiating air waves from the corresponding vent on the touchscreen. The air flows in a single stream when centered or splits into mirrored air streams when air is directed outward or inward from the center of the vent.

Note

When you split a vent into two separate air flows, the air flow in each direction is not as strong as when all air is flowing in a single direction.

Note

Outside air is drawn into Model 3 through the grill in front of the windshield. Keep the grill clear of obstructions, such as leaves and snow.

Adjusting the Rear Vents

Model 3 has vents located at the back of the center console where air flows from when the setting is turned on from the touchscreen. To direct the flow of air in the rear cabin area, adjust the vents at the rear of the center console up, down, or from side to side as necessary.

Keep Climate On, Dog Mode, and Camp Mode

The Keep Climate On, Dog, and Camp settings allow you to keep the climate control system running when in Park, even after you've left Model 3 or choose to stay inside the vehicle. These settings are useful when it is important to maintain the cabin temperature in hot or cold weather conditions. For example, when leaving groceries in Model 3 on hot days, you may want to use Keep Climate On to prevent spoilage.

Dog Mode is designed to maintain a comfortable cabin temperature for your pet while you actively and frequently monitor this temperature using the mobile app (which requires both your phone and the vehicle to have cellular connectivity). When in Dog Mode, the touchscreen displays the current cabin temperature to inform people passing by that your pet is safe. This setting is not intended for people, and should only be used for short periods of time while you stay in close proximity should you need to return to the vehicle in situations where the temperature can no longer be maintained.

Camp Mode allows you to power electronics through the USB ports and low voltage outlet in addition to maintaining the cabin temperature. The touchscreen remains on so you can play music, browse the internet, play games in the arcade, or watch shows in Tesla Theater. You can also control media and climate settings from a paired phone. Camp Mode is ideal for remaining inside your vehicle, such as camping or staying with a child. While active, Sentry Mode and the vehicle alarm system are disabled.

To operate Keep Climate On, Dog Mode, or Camp Mode:

1. Make sure the Battery's charge level is at least 20%.
2. Engage Park. The Keep Climate On, Dog, and Camp settings are available only when Model 3 is in Park.
3. If necessary, adjust the climate settings.
4. Touch the fan icon then touch Keep Climate On, Dog, or Camp.

The climate control system attempts to maintain your climate settings until you shift out of Park or manually turn it off. Avoid using Keep Climate On, Dog Mode, or Camp Mode when the battery charge is low. If the Battery's charge level drops below 20%, the Tesla mobile app attempts to repeatedly send you notifications reminding you to check on anything that you have left in Model 3 .

Note

Software updates cannot be performed when Keep Climate On, Dog Mode, or Camp Mode is active.

Note

The intrusion sensor (if equipped) automatically disables when Keep Climate On, Dog Mode, or Camp Mode is active. However, you can override this behavior and keep the intrusion sensor enabled. To do so, touch after enabling Keep Climate On, Dog Mode, or Camp mode. However, note that keeping the intrusion sensor enabled while Keep Climate On, Dog Mode, and Camp Mode is active can trigger an alarm event as a result of air movement inside the cabin.

Warning

Never leave a child unattended in your vehicle.

Warning

Check local laws for any restrictions on leaving pets unattended in your vehicle.

Warning

You are responsible for the safety of your dog or pet. Never leave them in Model 3 for long periods of time. Constantly monitor the vehicle temperature and their well-being. Make sure you have sufficient cellular coverage on your phone and time to return to the vehicle, if necessary.

Warning

In the unlikely even that your climate control system needs service or is not working as expected, avoid using Keep Climate On, Dog Mode, and Camp Mode. Never rely on your vehicle to protect something irreplaceable.

Warning

You can adjust and monitor the climate control system remotely using the mobile app. However, if you use the mobile app to turn off the climate control system, Keep Climate On, Dog Mode, and Camp Mode stop operating.

Cabin Air Filter(s)

Model 3 has one or more air filters to prevent pollen, industrial fallout, road dust and other particles from entering through the vents.

Note

Cabin air filter(s) require periodic replacement. See Service Intervals.

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 and choose:

• OFF: Disable Cabin Overheat Protection.
• NO A/C: Only the fan operates when the cabin temperature exceeds 40° C. This option consumes less energy but the cabin temperature may exceed 40° C.
• ON: The air conditioning operates when the cabin temperature exceeds 40° C.

Note

Cabin Overheat Protection operates until 12 hours has elapsed since you exited Model 3 , or until the Battery energy drops below 20%, whichever comes first.

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.
• 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 low voltage 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 grille 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.
• Model 3 is designed to automatically maximize efficiency; therefore, your air conditioning compressor and external fan may run and make noise even when the outside temperature is cold and your vehicle is heating or supercharging.
• 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%.
