Installation:
1.
Remove the protective caps from the positive (+) and negative (-) posts on the new low voltage lead-acid battery.
2.
Carefully place the new lead-acid battery in the vehicle, taking care not to damage nearby
components.
3.
Install the low voltage lead-acid battery hold down
and use a 10mm socket to tighten the nut that secures it to the battery. Torque the nut to 6 Nm (4.4
ft-lb).
4.
Reconnect the first responder loop.
5.
Reconnect the positive (+) terminal by positioning
the terminal clamp over the terminal post. Using a 10mm socket, torque the nut to 6 Nm (4.4 ft-lb). Reinstall the positive (+) terminal cover.
6.
Reconnect the negative (-) terminal by positioning
the terminal clamp over the connector. Using a 10mm socket, torque the nut to 6 Nm (4.4 ft-lb).
7.
Connect the vent tube hose into the negative (-) terminal side of the low voltage lead-acid battery.

Displaying Tire Pressures
Tire pressures display on the touchscreen in the cards
area on the car status display, or by touching Controls >
Service. The pressure of each tire displays in the
visualization of your
Model 3, in addition to what time
your tire pressures were last measured. You can choose
whether you want to display tire pressures using Bar or PSI by touching
Controls > Display > Tire Pressure. The
touchscreen also displays your vehicle

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 179). 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 214) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model 3, see Wheels and Tires on page 213.
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-
or
over-inflated (see Automatic Reset of TPMS Sensors on
page 180).
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

3. Lift the wiper arm a short distance away from the windshield, just far enough to access the wiper blade.CAUTION: Wiper blades do not lock into a lifted
position. Do not lift a wiper arm beyond its
intended position.
4.
Place a towel between the wiper arm and windshield to avoid scratching or cracking the windshield.
5.
Hold the wiper arm and press the locking tab while sliding the blade down the arm.
6.
Align the new wiper blade on the wiper arm and slide
it toward the end of the wiper arm until it locks into place.
7.
Turn Wiper Service Mode off to return the wipers to
their normal position.
Cleaning Washer Jets
If a windshield washer becomes blocked, use a thin
strand of wire to clear any blockages from the nozzles.
WARNING: Do not operate the washers while
cleaning Model 3. Windshield washer fluid can
irritate eyes and skin. Read and observe the
washer fluid manufacturer

Replacing the Low Voltage Lead-Acid Battery
This procedure is intended for vehicles in North America
only.
CAUTION: To avoid damage that is not covered by
the warranty, replace your low voltage lead-acid
battery with the same type of battery. The low
voltage lead-acid battery for North American
vehicles is AtlasBX / Hankook 85B24LS 12V 45Ah.
You can purchase a new lead-acid low voltage
battery that is compatible with your vehicle from
your local service center
NOTE: Vehicles manufactured between approximately
July 2017 and October 2020 do not have a heat pump and should use
Vehicles Manufactured Before
Approximately October 2020 on page . Vehicles
manufactured afterward have a heat pump and should
use
Vehicles Manufactured After Approximately October
2020 on page .
Perform the following procedure to replace the lead- acid low voltage battery. Wear appropriate personal protection equipment (such as safety glasses, leather gloves when handling the lead-acid battery etc.).
Vehicles Manufactured Before
Approximately October 2020
Removal:
1.
Prepare the vehicle to remove the low voltage lead-
acid battery:
a.
Ensure the vehicle is in Park.
b.
Lower all windows.
c.
Open the front trunk.
d.
Leave a door propped open so you can get back
into the vehicle if needed.
e.
Disconnect the charge cable from the charge port.
2.
Move the driver and front passenger seat fully forward.
3.
Under the rear seat, press the left and right tabs to the side and lift the seat cushion up. The seat separates from the base but is still restrained by one wire harness on each side.
4.
Disconnect the wire harnesses and remove the seat cushion. Set the cushion aside.
5.
In the front trunk, remove the vehicle
