For one-touch access to seat heaters, you can add them to the touchscreen’s bottom bar (see Customizing My Apps).
When in Park, these settings display to allow you to keep the climate control system operating, even when you leave Model S (see Keep Climate On, Dog, and Camp).
Touch to adjust how air flows from the front vents. See Adjusting the Front and Rear Vents.
When Model S is in Park, touch Schedule to set a recurring daily time when you want Model S 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).
If your Model S is equipped with the medical-grade HEPA (High Efficiency Particulate Air) filter, this filter ensures the best quality air inside the cabin whenever the climate control system is on and outside air is entering the cabin (recirculate is off). The HEPA filter is extremely effective at removing particles, including pollution, allergens, bacteria, pollen, mold spores, and viruses. Both the HEPA filter and the secondary filtration system also contain activated carbon to remove a broad spectrum of odors and gases. When you engage Bioweapon Defense Mode, the positive pressure inside the cabin minimizes the amount of outside air that can enter the vehicle.

Note

Some gases, such as carbon monoxide, are not effectively removed by activated carbon.
Touch to control the flow of air inside the cabin. Air can be drawn into Model S from outside or air can be recirculated inside the cabin.
Use the slider to adjust the fan speed.

Note

Adjusting the fan speed may change the selected setting for how air is drawn into Model S in order to increase or reduce air flow.
Touch to turn the air conditioning system on or off. Turning it off reduces cooling, but saves energy.

Note

Because Model S 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.

Rear controls

Using the touchscreens, you can pinpoint exactly where you want to direct the air flowing from this vent when heating or cooling the cabin. 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, 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 airflow in each direction is not as strong as when all air is flowing in a single direction.

Note

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

Keep Climate On, Dog, and Camp

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 S 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 S on hot days, you may want to use Keep Climate On to prevent spoilage.

Dog 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, 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 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 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, or Camp:

Make sure the Battery’s charge level is at least 20%.
Engage Park. The Keep Climate On, Dog, and Camp settings are available only when Model S is in Park.
If necessary, adjust the climate settings.
On the climate controls screen, touch Keep Climate On, Dog, or Camp.

Note

You can also control Dog and Camp from the mobile app, by swiping up the gray bar on the Climate screen.

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, or Camp 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 S.

Note

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

Note

The intrusion sensor (if equipped) automatically disables when Keep Climate On, Dog, or Camp is active. However, you can override this behavior and keep the intrusion sensor enabled. To do so, touch Controls > Safety > Tilt/Intrusion after enabling Keep Climate On, Dog, or Camp. However, note that keeping the intrusion sensor-enabled while Keep Climate On, Dog, or Camp 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 S 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 event that your climate control system needs service or is not working as expected, avoid using Keep Climate On, Dog, and Camp. 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, and Camp stop operating.

Cabin Air Filter(s)

Model S 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 S. Touch Controls > Safety > Cabin Overheat Protection and choose:

Off: Disable Cabin Overheat Protection.
On: The air conditioning operates when the cabin temperature exceeds 105° F (40° C).

Note

Cabin Overheat Protection operates until 12 hours have elapsed since you exited Model S, 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

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 S 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 S 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%.
