3. Rear trunk - Double-click to open the rear trunk. Hold down for one to two seconds to open the
charge port door.
Once inside, power up Model Y by pressing the brake
pedal within two minutes of pressing the unlock button
on the key fob (see
Starting and Powering Off on page
49). If you wait longer than two minutes, you must
press the unlock button again, or place the key fob near
the card reader located behind the cup holders on the center console. When your key fob is detected, the two
minute authentication period restarts.
When approaching or leaving Model Y carrying the key
fob, you do not need to point the key fob at
Model Y as
you press a button, but you must be within operating range.
Radio equipment on a similar frequency can affect the
key. If this happens, move the key at least
one foot
(30 cm) away from other electronic devices (phone,
laptop, etc.).
If the key fob does not work (for example, its battery is dead), you can touch its
flat side against the card
reader on the driver

While avoiding touching the battery

NOTE: Applying external 12V power to these
terminals only releases the hood latches. You cannot
charge the 12V battery using these terminals.6.
Turn on the external power supply (refer to the manufacturer’s instructions). The hood latches are immediately released and you can now open the
hood to access the front trunk area.
7.
Disconnect both cables, beginning with the black
negative (-) cable.
8.
If pulling the vehicle onto a flatbed truck, do not
replace the tow eye cover yet. If necessary, replace the tow eye cover by inserting the wires into the tow eye opening and aligning the tow eye cover into
position and turning it into place.
Front Trunk
20MODEL Y OWNER

Open the center console door below the touchscreen
and lift the phone dock upward to access the front USB ports.
Two additional USB ports are located in the rear of the center console (on vehicles manufactured since
approximately June 2020, these ports are USB-C). These ports charge USB-connected devices but do not communicate with the vehicle.
NOTE: Power is available whenever the vehicle is
considered "awake". The vehicle may be awake for
many reasons. For example, when using features such as Summon, or when features such as Cabin Overheat
Protection, Keep Climate On, Dog Mode,
Sentry Mode,
etc. are enabled. The vehicle is also awake whenever the 12V battery is being charged or is in use, during HV charging, when the vehicle is communicating with the mobile app, etc. Leaving an accessory plugged in does not deplete the 12V battery.
NOTE: Use USB 3.0 compliant cables to connect a
device to a USB port. Using non-compliant cables can result in slower charging, potential connection problems or degraded performance.
NOTE: Do not connect multiple devices using a USB
hub. This can prevent connected devices from charging or from being recognized by Media Player
, Sentry
Mode, Dashcam, etc.
Installing Phone Charging Cable
To make it easy to connect your phone while keeping
the console free of clutter, you can install a phone charging cable in
Model Y.
NOTE: The phone dock supports two phones side-by-
side.
To install a phone charging cable:
1.
Open both center console doors in front of the cup
holders.
2.
Remove the rubber mat from the phone dock.
3.
Lift the phone dock to access the USB ports.
4.
Release the cover from the base of the phone dock by sliding it to the left.
5.
Plug the USB connector on the phone charging cable into a USB port.
6.
Insert the phone end of the charging cable through the bottom of the phone dock and route the cable through the securing tabs towards the bottom of the phone dock.

plugged in, you can heat your Battery by
turning on climate control with the
mobile app. The snowflake icon

WARNING: Always maintain a safe driving
distance from the vehicle in front of you and
exercise caution when driving conditions are
hazardous. Do not rely on brake disc wiping or
hydraulic fade compensation to act as a
substitute for adequately applying the brakes.
Hydraulic Boost Compensation
Model Y is equipped with a brake booster that provides
a mechanical advantage that
effectively activates the
brakes when the brake pedal is pressed. Hydraulic boost
compensation provides mechanical assist in the event of a brake booster failure. If a brake booster failure is detected, the brake pedal may feel harder to press and you may hear some noise when you press the brake
pedal. To stop the vehicle, apply adequate steady force on the brake pedal without releasing or "pumping" them. Exercise caution while driving and maintain a safe
distance as brake pedal responsiveness and braking performance may be degraded.
Regenerative Braking
Whenever Model Y is moving and your foot is off the
accelerator, regenerative braking slows down
Model Y
and feeds any surplus energy back to the Battery.
By anticipating your stops and reducing or removing
pressure from the accelerator pedal to slow down, you
can take advantage of regenerative braking to increase
driving range. Of course, this is no substitute for regular
braking when needed for safety.
NOTE: If regenerative braking is aggressively slowing
Model Y (such as when your foot is completely off the
accelerator pedal at highway speeds), the brake lights turn on to alert others that you are slowing down.
NOTE: Installing winter tires with aggressive compound
and tread design may result in temporarily-reduced regenerative braking power. However, your vehicle is
designed to continuously recalibrate itself, and after changing tires it will increasingly restore regenerative braking power after some moderate-torque straight-line accelerations. For most drivers this occurs after a short period of normal driving, but drivers who normally
accelerate lightly may need to use slightly harder accelerations while the recalibration is in progress.
WARNING: In snowy or icy conditions Model Y
may experience traction loss during regenerative
braking.
The amount of energy fed back to the Battery using regenerative braking can depend on the current state of the Battery. For example, regenerative braking may be
limited if the Battery is already fully charged or if the
ambient temperature is too cold.
NOTE: If regenerative braking is limited, a dashed line
displays on the energy bar (see
Driving Status on page
57).
Stopping Mode
Regenerative braking decelerates Model Y whenever you
release the accelerator pedal when driving. You can
choose what you want
Model Y to do once the driving
speed has been reduced to a very low speed (almost at
a stop) and both the accelerator pedal and brake pedal
are released. While in Park, touch
Controls > Driving >
Stopping Mode and choose from these options:

To ensure that Model Y provides you with the best
ownership experience possible in harsh cold weather
conditions, follow these best practices.
Before Driving
When snow and ice accumulate on your vehicle, moving
parts, such as the door handles, windows, mirrors, and
wipers can freeze in place. For these reasons, and to
achieve maximum range and performance, it is helpful to warm the cabin and Battery before you leave. There are several ways to do so:

While Driving
Cold weather can increase energy consumption because more power is required for driving, cabin and Battery heating. Follow these suggestions to reduce
energy consumption:

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
