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

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.
Using RFID Transponders
When attaching an RFID transponder (used by many
automated toll systems) inside
Model Y, place the
transponder
on the passenger side of the rear view
mirror as shown. This ensures best results and minimizes
any obstruction to your driving view.
NOTE: You can also attach a weather-proof transponder
to the front license plate.
Installing Front License Plate
Bracket
To accommodate jurisdictions that require a license plate on the front of your vehicle,
Model Y is equipped
with a license plate bracket. This bracket conforms to
the shape of your vehicle

1. Ensure Model Y is in Park.2.
Chock the tires or make sure Model Y is secure.
3.
Press and hold the brake pedal, then on the touchscreen, touch
Controls > Service > Towing. The
touchscreen displays a message reminding you how
to properly transport
Model Y.
4.
Press and hold the Transport Mode button until it
turns blue.
Model Y is now free-rolling and can slowly
be rolled (no faster than walking speed) or winched.
To cancel Transport Mode, shift Model Y into Park.
NOTE: If your vehicle is equipped with a lead-acid low
voltage battery (see
Jump Starting on page 227):
Transport Mode may cancel if
Model Y loses low voltage
power after Transport Mode is enabled.
CAUTION: If the electrical system is not working,
and you therefore cannot use the touchscreen to
activate Transport Mode, use self-loading dollies or
tire skates. Before doing so, always check the
manufacturer
Page 228 of 298
NOTE: In the unlikely event your vehicle runs out of
range while driving, pull over when safe to do so and contact
Tesla Roadside Assistance on page 222 or your
preferred tow provider.
If Model Y runs out of range, the low voltage battery is
no longer supported

The procedure for jump starting differs depending on
whether the low voltage battery is lead-acid or lithium- ion. To determine which battery your vehicle uses, touch
Controls > Software > Additional Vehicle Information.
Both procedures are provided in this section.
The following instructions assume you are using an external
low voltage power supply (such as a portable
jump starter). If jump starting
Model Y using another
vehicle, refer to the vehicle manufacturer
