• When you use the mobile app to turn on the climate
control system, it automatically turns off when the
charge level drops to 20%, or if two hours has passed.
To cool or heat the cabin for a longer period of time,
charge the vehicle and re-enable your climate control
preference through the mobile app.
• 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%.
• 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.
• You may hear the sound of the climate system inside
the cabin of Cybertruck when parked. It makes a low
fan noise. The climate system attempts to dry itself
out to minimize additional moisture or musty odors.
This is a normal operation and not a cause for
concern.
• Even when not in use, you may hear Cybertruck 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.
• 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
Cybertruck when parked. Extra water produced by
the dehumidifying process is drained underneath.
Tips:
• If the climate control system is louder than you prefer,
manually reduce the fan speed.
• Improve the efficiency of the cabin heating or cooling
by reducing your rate of acceleration. This allows the
heat pump system to take more heat from the
Battery to efficiently heat the cabin, instead of
maintaining the Battery's ability to provide peak
acceleration performance. Note that when
subsequently increasing the acceleration mode, the
Battery requires time to warm up before the
increased level of acceleration is available.
• 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.
• 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 your vehicle is
not Supercharging due to the latch being frozen in
place, enable Defrost Truck in the mobile app. This

helps thaw ice on the charge port latch so the charge
cable can be removed or inserted. See
