Parts, Accessories, and Modifications

Use only genuine Tesla parts and accessories. Tesla performs rigorous testing on parts to ensure their suitability, safety, and reliability. Purchase these parts from Tesla, where they are professionally installed and where you can receive expert advice about modifications to Model 3. Accessories are available for purchase from Tesla stores or online at www.tesla.com.

Note
Some accessories may not be available in your market region.

Tesla is unable to assess parts manufactured by other distributors and therefore accepts no responsibility if you use non-Tesla parts on Model 3.

Warning
Installing non-approved parts and accessories, or performing non-approved modifications, can affect the performance of Model 3 and the safety of its occupants. Any damage caused by using or installing non-approved parts, or by performing non-approved modifications, is not covered by the warranty.

Warning
Tesla does not accept liability for death, personal injury or damage that occurs if you use or install non-approved accessories or make non-approved modifications.

Body Repairs

If your Model 3 is in a collision, contact Tesla or a Tesla-approved Body Shop to ensure that it is repaired with genuine Tesla parts. Tesla has selected and approved body shops that meet strict requirements for training, equipment, quality, and customer satisfaction.

Some repair shops and insurance companies might suggest using non-original equipment or salvaged parts to save money. However, these parts do not meet Tesla's high standards for quality, fit and corrosion resistance. In addition, non-original equipment and salvaged parts (and any damage or failures they might cause) are not covered by the warranty.

Replacing Cabin Filters

Model 3 has air filters that prevent pollen, industrial fallout, road dust, and other particles from entering the cabin through the vents. Tesla recommends replacing these filters every 2 years (every year in China). Cabin filters can be purchased at the Tesla online store.

To replace the cabin filters:

  1. Turn off the climate control system.

  2. Move the front passenger seat fully rearwards and remove the front passenger floor mat.

  3. Working from top-to-bottom, use a trim tool to carefully release the right side panel from the center console.

  4. Use a clip pry tool to carefully release the push clips that secure the front passenger footwell cover to the instrument panel. Then, while supporting the footwell cover, disconnect the two electrical connectors and move the footwell cover aside.

  5. Remove the T20 screw that secures the cabin filter cover to the heating, ventilation, and air conditioning (HVAC) module then release the cabin filter cover and move it aside.

    Informational PurposesAn informational icon, calling your attention
    Note
    If the HVAC module does not have a cabin filter cover, reinstall the trim panels and contact Tesla.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    Warning
    Do not stretch, bend, or otherwise damage the orange High Voltage (HV) cables that are attached to the cabin filter cover. If the HV cables are damaged, immediately discontinue this procedure. HV shock can result in serious injury or death.
  6. Fold the upper cabin filter’s tab upward and the lower filter’s tab downward.

  7. Holding the tab on the upper cabin filter, pull the upper filter out from the HVAC module.

  8. Holding the tab on the lower cabin filter, pull the lower filter upwards and then out from the HVAC module.

  9. Ensuring that the arrows on both new filters face towards the rear of the vehicle, insert the lower cabin filter into the HVAC module and lower it into place. Then, insert the upper cabin filter above it.

  10. Fold the tabs inward so that the cabin filter cover can be installed.

  11. Install the cabin filter cover by engaging the lower cover tab then securing the T20 screw using. Tighten the screw to 1.2 Nm/0.89 ft-lbs.

  12. Reconnect the two electrical connectors to the components in the front passenger footwell cover, then resecure the cover with the push clips.

  13. Align the right side panel with the front and rear locator slots on the center console, then apply pressure until all of the clips are fully secure.

  14. Reinstall the front passenger floor mat then move the front passenger seat back into place.

Replacing the Low Voltage Lead-Acid Battery

This procedure is intended for vehicles in North America only.
Warning IconA warning icon, calling your attention to a possibly risky situation
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
Informational PurposesAn informational icon, calling your attention
Note
Vehicles manufactured before approximately October 2020 do not have a heat pump and should use the first procedure. Vehicles manufactured afterward have a heat pump and should use the second procedure.

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
