WARNING: Never leave children or pets in the
vehicle unattended. Due to automatic shut-o 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 o 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 your vehicle 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 eective). This helps thaw ice on
the charge port latch so the charge cable can be
removed or inserted. See Cold Weather Best
Practices on page 77 for more information.
•
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
o. 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
eciently, 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%.
