Climate Control Operating Tips; Cabin Air Filter - Tesla MODEL S Operating Manual

Note: You can direct the outer face level vents
toward the side windows to help defrost or
defog them.

Cabin Air Filter

Model S 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.
Tesla recommends replacing the HEPA air
filter (if equipped) every 3 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 S. 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 105° F (40° C).
This option consumes less energy but the
cabin temperature may exceed 105° F
(40° C).
• ON: The air conditioning operates when
the cabin temperature exceeds 105° F
(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

• 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.
• To conserve energy, turn on Range Mode
to limit the power of the climate control
system (touch Controls > Driving > Range
Mode). Cabin heating and cooling may be
less effective, but you can use seat
heaters to provide warmth in colder
climates.
• 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 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 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%.
