With a 10mm socket, loosen the nut and release the
battery hold down from the top of the low voltage
lead-acid battery by unhooking and sliding it back, taking care to ensure it does not slip into the vehicle.
13.
Using the battery handle, carefully remove the low
voltage lead-acid battery, taking care not to touch or damage the surrounding components.
WARNING: When lifting the low voltage lead-
acid battery, stand in front of the vehicle and
use proper lifting technique. The low voltage
battery weighs approximately 25 lb (12 kg).
Failure to do so may cause serious injury.Maintenance Service Intervals

14.
Inspect the new low voltage lead-acid battery to ensure it is equipped a red plug on the positive (+) terminal side. If the new low voltage battery does not have a red plug, use a small trim tool transfer the red plug from the old battery to the new one.
CAUTION: Dispose of the old low voltage lead-
acid battery according to local laws, such as
dropping it off at a battery recycling facility.
Keep the low voltage battery upright and place
it on a towel or piece of cardboard when
transporting it.
Installation:
1.
Remove the protective caps from the positive (+) and negative (-) posts on new low voltage lead-acid
battery.
2.
Carefully maneuver the new low voltage battery into place, taking care not to touch or damage nearby
components.
3. Install the low voltage battery hold down and use a
10mm socket to tighten the bolt that secures it to the low voltage lead-acid battery. Torque the bolt to 6
Nm (4.4 ft-lb).4.
In the rear passenger seat, connect the penthouse cable to the connector:
a.
Ensure the gray lever-arm is down, then install the
connector.
b.
Secure the connector by gently tugging the gray
lever-arm upward until it clicks into place.
c.
Replace the foam cover on top of the penthouse cable.

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
