• Check that the air conditioning system is operating
correctly (see Operating Climate Controls on page
146).
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
Cybertruck 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.
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
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 Cybertruck 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 Cybertruck. 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.
Maintenance
Maintenance Service Intervals
• 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: Assume that the low voltage
components of Cybertruck, including all cables
and connectors, are always energized. 48V low
voltage connectors are colored blue for easy
identification, and wires that operate at 48V are
marked with blue tape.
Do not handle low voltage cables or connect/
disconnect connectors when the low voltage
system is powered. Because the 48V low voltage
system operates at a higher voltage than a typical
low voltage system, there is an increased risk of
personal injury, arcing, or component damage if
the low voltage components of Cybertruck are
handled improperly.
WARNING: Always disconnect the charge cable
before working underneath Cybertruck, even if
charging is not in progress.
WARNING: Keep your hands and clothing away
from cooling fans. Some fans operate even when
Cybertruck 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.
