TESLA MODEL Y 2023 Owners Manual

3.
If equipped, remove the HEPA filter:
a.
Using a 10mm socket, remove the bolt that attaches the washer
fluid reservoir neck to the
underhood storage unit.
b.
Remove the washer tank neck from the vehicle. If
the windshield washer reservoir is full, some
washer
fluid may leak out.
NOTE: You do not need to remove the hose from
the neck.
c.
With a 10mm socket, remove the bolts (x2) that
attach the HEPA
filter assembly to the vehicle.
d.
Remove the HEPA filter assembly from the vehicle
by tilting the rear edge of the
filter assembly up
past the brake
fluid reservoir. Lift the filter
assembly out of the vehicle, taking care not to
bump into or damage other components.

4. Power off the vehicle by navigating to Controls >
Safety > Power Off on the touchscreen.
5.
Disconnect the first responder loop by sliding the red
locking tab toward you and pressing the black tab.
6.
With a 10mm socket, loosen the nut that secures the
negative (-) terminal clamp to the negative (-) post on the lead-acid battery. Release the terminal clamp from the negative (-) post.
7.
With a 10mm socket, release the terminal cover and loosen the nut that secures the positive (+) terminal
clamp to the positive (+) post on the lead-acid
battery. Release the terminal clamp from the positive
(+) post and cover the terminal clamp with a dry rag.
CAUTION: Do not allow the positive (+)
terminal clamp to contact nearby components
like the lead-acid battery hold down bracket or
A/C cooling lines.
8.
Unplug the vent tube hose from the negative (-)
terminal side of the lead-acid battery.
9.
Loosen the nut on the battery hold down on the top of the lead-acid battery with a 10mm socket. To
release the battery hold down, unhook and slide the
strap back. If needed, tilt the battery hold down
backward so it does not slip into the vehicle.
10.
Using the battery handle, carefully remove the lead- acid battery, taking care not to touch or damage the surrounding components.

WARNING: When lifting out the lead-acid
battery, stand in front of the vehicle and use
proper lifting technique. The lead-acid battery
weighs approximately 25 lb (12 kg). Failure to
do so may cause serious injury.
11.
Inspect the new lead-acid battery to ensure it has a
red plug in the casing on the positive (+) terminal
side. If the new lead-acid battery does not have a red plug, use a small trim tool to transfer the red plug
from the old battery to the new one.
CAUTION: Dispose of the old lead-acid battery
according to local laws, such as dropping it off

at a battery recycling facility. Keep the lead-
acid battery upright and place it on a towel or
piece of cardboard when transporting it.
Installation:
1. Carefully maneuver the new lead-acid battery into
place, taking care not to touch or damage nearby
components.2.
Install the lead-acid battery hold down and use a 10mm socket to tighten the nut that secures it to the 12V battery. Torque the nut to 6 Nm (4.4 ft-lb).
3.
Reconnect the first responder loop.
4.
Remove the protective caps from the positive (+) and negative (-) posts on the new low voltage lead-acid battery.
5.
Connect the positive (+) terminal by positioning the
clamp over the positive (+) post. Using a 10mm socket, torque the nut to 6 Nm (4.4 ft-lb).

6.
Install the positive (+) terminal cover.
7.
Connect the negative (-) terminal by positioning the
clamp over the negative (-) post. Using a 10mm socket, torque the nut to 6 Nm (4.4 ft-lb).
8.
Connect the vent tube hose into the negative (-) terminal side of the lead-acid battery.
9.
Open one of the vehicle

d. Route the hose so that it is secured by the tab.e.
Use a 10mm socket to install the bolt that attaches the washer
fluid reservoir neck to the underhood
storage unit. Torque the bolt to 5 Nm (3.7 ft-lb).
11.
Replace the underhood apron by aligning the clips into their openings in the front trunk. Press down to lock them in place. The clips make an audible clicking
sound when secured.
12.
Close the front trunk. If an alert to replace the low-
voltage battery was previously shown on the
touchscreen, ensure the alert no longer appears.

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 Y, 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

WARNING: Do not drive Model Y if a tire is
damaged, excessively worn, or inflated to an
incorrect pressure. Check tires regularly for wear,
and ensure there are no cuts, bulges or exposure
of the ply/cord structure.
Tire Wear
Adequate tread depth is important for proper tire
performance. Tires with a tread depth less than
4/32

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

2.
Push firmly around the perimeter of the aero cover
until it fully snaps into place.
For Gemini wheels, press on the perimeter of the cover until it aligns with the wheel surface. Press on the Tesla

WARNING: Only use Tesla-approved wheels when
installing or swapping wheels. Using non Tesla-
approved wheels can cause serious damage. Tesla
is not liable for damage caused by using wheels
not approved by Tesla.
