Tesla MODEL 3 2020 Owner's Manual page 161

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 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
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.
• If the climate control system is louder
than you prefer, manually reduce the fan
speed.
Using the Touchscreen
Climate Controls
• 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%.
