operate at three levels from 3 (highest) to 1 (lowest).
To
operate the seat heaters, see Climate Controls on page
125.
WARNING: To avoid burns resulting from
prolonged use, individuals who have peripheral
neuropathy, or whose capacity to feel pain is
limited because of diabetes, age, neurological
injury, or some other condition, should exercise
caution when using the climate control system
and seat heaters.
Seat Covers
WARNING: Do not use seat covers in Model Y.
Doing so could restrict deployment of the seat-
mounted side air bags if a collision occurs. Also, if
the vehicle is equipped with an occupant
detection system that is used to determine the
status of the passenger front airbag, seat covers
may interfere with this system.

Condensation can form inside the camera enclosures, especially if you park your vehicle outside in cold or wet
conditions. The
touchscreen may display an alert stating
that a camera is blocked and that some or all Autopilot
features may be temporarily restricted until the camera vision is clear. To proactively dry the condensation, precondition the cabin by setting it to a warm temperature, turning the windshield defroster on, and directing the front air vents toward the door pillars (see
Mobile App on page 151).
CAUTION: Do not use chemical-based or abrasive
cleaners. Doing so can damage surfaces.
CAUTION: Avoid using a high-pressure power
washer.
CAUTION: Do not clean an ultrasonic sensor or
camera lens with a sharp or abrasive object that
can scratch or damage its surface.

Overview of Climate Controls
Climate controls are always available at the bottom of the touchscreen. To turn the climate control system on, touch
the fan icon or adjust the cabin temperature. To turn it
off, touch the fan icon and then touch the off button near the
center of the popup window.
By default, climate control is set to the Auto setting, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the cabin temperature in the Auto setting, the system automatically adjusts the
heating, air conditioning, air distribution, and fan speed to maintain the cabin at your selected temperature. To
override the Auto setting, touch the fan icon, turn
off the Auto setting, then manually adjust your settings (see
Adjusting Climate Control Settings on page 125). If you

In addition to the settings shown, if Model Y is in Park, the Keep Climate On, Dog Mode, and Camp Mode setting

4.
Choose where air flows into the cabin (windshield, face-level, or foot-level vents). You can choose more than
one location.
NOTE: When air is directed to the foot-level vents, air continues to flow to the windshield vents to assist in
defogging. When air is directed to the face-level vents, air does not
flow to the windshield.
5.
Touch to turn air flow to the rear cabin area on or off. When on, air flows from the vents located at the back of
the center console. See
Adjusting the Rear Vents on page 127.
6.
Touch to adjust air flow from the front passenger vent. See Adjusting the Front Vents on page 127.
7.

About the Battery
Model Y has one of the most sophisticated battery
systems in the world. The most important way to preserve the Battery is to
LEAVE YOUR VEHICLE
PLUGGED IN when you are not using it. This is
particularly important if you are not planning to drive
Model Y for several weeks. When plugged in, Model Y
wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery.
NOTE: When left idle and unplugged, your vehicle
periodically uses energy from the Battery for system tests and recharging the 12V battery when necessary.
There is no advantage to waiting until the Battery’s level is low before charging. In fact, the Battery performs best when charged regularly.
NOTE: If you allow the Battery to discharge to 0%,
other components may become damaged or require replacement (for example, the 12V battery). In these cases, you are responsible for repair and/or transporting expenses. Discharge-related expenses are
not covered by the warranty or under the Roadside Assistance policy.
The peak charging rate of the Battery may decrease slightly after a large number of DC Fast Charging sessions, such as those at Superchargers. To ensure maximum driving range and Battery safety, the Battery charge rate is decreased when the Battery is too cold, when the Battery’s charge is nearly full, and when the
Battery conditions change with usage and age. These changes in the condition of the Battery are driven by battery physics and may increase the total Supercharging duration by a few minutes over time.
Battery Care
Never allow the Battery to fully discharge. Even when
Model Y is not being driven, its Battery discharges very
slowly to power the onboard electronics. The Battery can discharge at a rate of approximately 1% per day, though the discharge rate may vary depending on environmental factors (such as cold weather), vehicle
configuration, and your selected settings on the
touchscreen. Situations can arise in which you must leave
Model Y unplugged for an extended period of
time (for example, at an airport when traveling). In
these situations, keep the 1% in mind to ensure that you leave the Battery with a
su

During Charging
During charging, the charge port light (the Tesla "T"
logo) pulses green, and the touchscreen displays the
charging status. The frequency at which the charge
port light pulses slows down as the charge level approaches full. When charging is complete, the light stops pulsing and is solid green.
NOTE: If Model Y is locked, the charge port light does
not light up.
If the charge port light turns red while charging, a fault
is detected. Check the touchscreen for a message describing the fault. A fault can occur due to something as common as a power outage. If a power outage
occurs, charging resumes automatically when power is
restored.
NOTE: When charging, particularly at high currents, the
refrigerant compressor and fan operate as needed to keep the Battery cool. Therefore, it is normal to hear sounds during charging.
NOTE: Air conditioning performance is generally not
affected by charging. However, under certain
circumstances (for example, you are charging at high currents during a particularly warm day), the air coming from the vents may not be as cool as expected and a message displays on the
touchscreen. This is normal
behavior and ensures that the Battery stays within an optimum temperature range while charging to support longevity and optimum performance.
WARNING: Never spray liquid at a high velocity
(for example, if using a pressure washer) towards
the charge port while charging. Failure to follow
these instructions can result in serious injury or
damage to the vehicle, charging equipment, or
property.
Stopping Charging
Stop charging at any time by disconnecting the charge
cable or touching
Stop Charging on the touchscreen.
NOTE: To prevent unauthorized unplugging of the
charge cable, the charge cable latch remains locked
and
Model Y must be unlocked or able to recognize
your
authenticated phone before you can disconnect
the charge cable.
To disconnect the charge cable using a connector:
1.
Press and hold the button on the connector handle to release the latch. Alternatively, unlock the vehicle
by opening a door, using a
key card or key fob, or
touching
Stop Charging on the touchscreen. These
methods unlock the charge port as well.
2.
Pull the connector from the charge port.
To disconnect the charge cable using an adapter at a
public charge station:
1. Ensure that Model Y is unlocked.2.
While holding the public charging handle in one
hand and the adapter in the other hand, press and hold the button on the public charging handle and
pull both outwards, removing the handle and
adapter at the same time.
NOTE: If the charging station handle separates from
the adapter, leaving the adapter in
Model Y, use the
touchscreen to unlock the charge port (touch the charging icon on the overhead view of the vehicle).
3.
Press and hold the charging handle button again to release the adapter from the charging handle.
NOTE: The charge port automatically closes within
approximately 10 seconds of removing the connector from the charge port.
CAUTION: Tesla strongly recommends leaving
Model Y plugged in when not in use. This
maintains the Battery at the optimum level of
charge.
CAUTION: Model Y will not shift out of Park if the
charge port is unable to determine whether a
charging cable is plugged in. Ensure any charging
cables are unplugged and follow the instructions
on the touchscreen to proceed (see Park on page
51.
Manually Releasing Charge Cable
If the usual methods for releasing a charge cable from the charge port (using the charge handle release button, touchscreen, or mobile app) do not work,
carefully follow these steps:
1.
Ensure that Model Y is not actively charging by
displaying the charging screen on the touchscreen. If necessary, touch
Stop Charging.
2.
Open the rear trunk.
3.
Pull the charge port

Removing the Maintenance Panel
To check fluid levels, remove the maintenance panel:
1.
Open the hood.
2.
Pull the maintenance panel upward to release the clips that hold it in place.
3.
If checking the Battery coolant, remove the cabin intake trim panel by pulling it upwards to release the clips that hold it in place.
CAUTION: The maintenance panel protects the
front trunk from water. When re-attaching, make
sure it is fully seated.
Checking Battery Coolant
Your Battery coolant should not need to be replaced for the life of your vehicle under most circumstances. However, if the quantity of
fluid in the cooling system
drops below the recommended level, the
touchscreen
displays a warning message. Stop driving Model Y as
soon as safety permits and contact Tesla.
Fluid Level Check
DO NOT REMOVE THE FILLER CAP AND DO NOT ADD
FLUID. Doing so can result in damage not covered by
the warranty.
Do Not Top Up Battery Coolant
WARNING: Battery coolant can be hazardous and
can irritate eyes and skin. Under no circumstances
should you remove the filler cap and/or add
coolant. If the touchscreen warns you that the
fluid level is low, contact Tesla immediately.
To maximize the performance and life of the Battery, the cooling system uses a
specific mixture of G-48
ethylene-glycol coolant (HOAT). Contact Tesla for more
specific information about the coolant.
Checking Brake FluidWARNING: Contact Tesla immediately if you
notice increased movement of the brake pedal or
a significant loss of brake fluid. Driving under
these conditions can result in extended stopping
distances or complete brake failure.
A red brake indicator on the
touchscreen alerts you if the quantity of
fluid in the brake reservoir drops below
the recommended level. If it displays while driving, stop as soon as safety permits by gently applying the brakes.
Do not continue driving. Contact Tesla
immediately.
Topping Up the Brake Fluid
Do not top up your brake fluid. The following
instructions are provided for information purposes and future reference only:
1.
Clean the filler cap before removing it to prevent dirt
from entering the reservoir.
2.
Unscrew the cap and remove it.
3.
Top up the reservoir to the MAX mark using the
appropriate brake
fluid.
4.
Replace the filler cap, ensuring it is fully secured.
WARNING: Only use new fluid from a sealed air-
tight container. Never use previously used fluid or
fluid from a previously opened container
