NOTE: 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. Also, even when not in use, you may hear
Model Y 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.
Periodic Checks
Perform the following checks as needed:
•
Over time, when driving in dusty or polluted conditions,
your vehicle's radiator may become clogged. This can
affect air flow and heating/AC performance.
To clean, do
it yourself by navigating to the Service Manual.
Alternatively, use the mobile app to schedule a service
appointment.
• The inside of the windshield within the camera enclosure
(see
Cameras on page 19) must be cleaned periodically to
maintain clear visibility and optimal camera function. To
check if such cleaning is needed, review your vehicle's
maintenance summary by touching Controls > Service >
Maintenance. When needed, use the mobile app to
schedule a service appointment.
Maintenance Summary
You can view current status of maintenance items by
navigating to Controls > Service > Maintenance on your
vehicle's touchscreen.
Maintenance Summary keeps track of when regular
maintenance items, such as windshield wiper blades and
filters, were last performed and provides suggestions for
when they should be performed again. You can
perform them
yourself or enlist the help of Tesla or an independent repairer.
Once completed, you can reset the maintenance item on your
vehicle's touchscreen.
Model Y captures a time stamp and
applicable information (such as your current mileage) and
resets the maintenance item to remind you for next time.
Vehicle service history records persist on the vehicle,
providing you and future owners with a record of previously
performed services. The service history record is not
affected by a factory reset.
NOTE: Although Tesla updates the maintenance summary
during a service visit as needed, it is the responsibility of the
vehicle's owner to ensure the accuracy of the information,
especially for service or maintenance performed by
independent repairers or through do-it-yourself means.
Fluid Replacement Intervals
Battery coolant and brake fluid levels should only be checked
by
Tesla or a professional automotive repair shop. Specific
service information is available in the Service Manual.
•
Battery coolant: Your Battery coolant does not need to be
replaced for the life of your vehicle under most
circumstances.
NOTE: Any damage caused by opening the Battery
coolant reservoir is excluded from the warranty.
•
Brake fluid: Do not top up your brake fluid.
Software
Updating software is important to ensure proper operation
and longevity of your vehicle's components. You must install
a software update at the earliest opportunity. See
Software
Updates on page 170.
Tesla may update or reinstall your vehicle's software as part
of the normal diagnostic, repair, and maintenance process
within Service.
High Voltage Safety
Your Model Y has been designed and built with safety as a
priority. However, be aware of these precautions to protect
yourself from the risk of injury inherent in all high-voltage
systems:
• Read and follow all instructions provided on the labels
that are attached to
Model Y. These labels are there for
your safety.
• The high voltage system has no user-serviceable parts.
Do not disassemble, remove or replace high voltage
components, cables or connectors. High voltage cables
are colored orange for easy identification.
• If a collision occurs, do not touch any high voltage wiring,
connectors, or components connected to the wiring.
• In the unlikely event that a fire occurs, immediately
contact your local fire emergency responders.
WARNING: Always disconnect the charge cable before
working underneath Model Y, even if charging is not in
progress.
WARNING: Keep your hands and clothing away from
cooling fans. Some fans operate even when Model Y is
powered off.
WARNING: Some fluids (Battery acid, Battery coolant,
brake fluid, windshield washer additives, etc.) used in
vehicles are poisonous and should not be inhaled,
swallowed, or brought into contact with open wounds.
For your safety, always read and follow instructions
printed on fluid containers.
