WARNING: In snowy or icy conditions the rear
wheels may not have sufficient traction to prevent
Model Y from sliding down a slope, particularly if
not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always
responsible for parking safely.
WARNING: Your Model Y may display an alert if
the road is too steep to safely park on, or if the
parking brakes are not properly engaged. These
alerts are for guidance purposes only and are not a
substitute for the driver
Page 89 of 298

NOTE: Installing winter tires can result in temporarily
reduced regenerative braking power but after a short
period of driving,
Model Y recalibrates to correct this.

select winter tires and quicken this process.
Blue Snowflake Icon
A blue snowflake icon appears on your
touchscreen when some of the stored energy in
the Battery is unavailable because the Battery is cold. This portion of unavailable energy displays in blue on the Battery meter. Regenerative
braking, acceleration, and charging rates may be limited. The
snowflake icon no longer displays
when the Battery is
sufficiently warm.
After Driving
Leave Model Y plugged in when not in use. This uses the
charging system, rather than the battery itself, to keep the battery warm (see
High Voltage Battery Information
on page 167).
Scheduled Departure
When parked, plug in Model Y and use the Schedule
settings, available on both the charging and climate
control screens, to set a time when you want to precondition
Model Y (see Scheduled Charging and
Scheduled Departure on page 174). Your vehicle
determines the appropriate time to begin charging so it is complete during
off-peak hours and the cabin and
Battery are warm by your set departure time. For more information, see
Scheduled Charging and Scheduled
Departure on page 174.
Storage
If you leave Model Y parked for an extended period of
time, plug the vehicle into a charger to prevent normal range loss and to keep the Battery at an optimal temperature. Your vehicle is safe to stay plugged in for any length of time.
When not in use, Model Y enters a sleep mode to
conserve energy. Reduce the number of times you check
your vehicle

When a tire set becomes worn, replace all four tires at
the same time. Choose a Tesla-approved tire which is
designed
specifically for your vehicle. Most Tesla-
approved tires can be
identified with a Tx specification
(for example, T0, T1, T2). Tesla-approved tires are
designed to reduce road noise and optimize handling, ride, and range. Contact Tesla Service for information.
If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
If you
replace your tires or install different ones, reset the tire
configuration (see Tire Configuration on page 188). This
resets the learned tire settings and improves the driving
experience on your new tires.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 216) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model Y, see Wheels and Tires on page 215.
If you replace a wheel, the TPMS (Tire Pressure Monitoring System) sensors need to be reset to ensure they provide accurate warnings when tires are
under-
inflated (see Automatic Reset of TPMS Sensors on page
188).
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. Go to
Service > Wheel & Tire Configuration > Tires to select
winter tires and quicken this process.
WARNING: For your safety, use only tires and
wheels that match the original specification. Tires
that do not match the original specification can
affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your
vehicle

Uniform Tire Quality Grading
The following information relates to the tire grading system developed by the National Highway Traffic Safety
Administration (NHTSA), which grades tires by tread wear, traction and temperature performance. Tires that have
deep tread, and winter tires, are exempt from these marking requirements.
Where applicable, quality grades are found on the tire
