When using the tow package to carry accessories, the 2" x 2" (5 cm x 5 cm) square hitch receiver is designed to support vertical loads of up to 160 lbs (72 kg). Ball mounts that are compatible with the square receiver must be purchased separately.
To install and use an accessory carrier, you must first attach the ball mount to the hitch receiver (see Attaching and Removing the Ball Mount). Then, follow the instructions provided by your accessory carrier. Observe all regulations and legal requirements in your state or region that apply to carrying accessories.
The Model Y towing package includes the wiring necessary for using an accessory carrier equipped with lights (see Electrical Connections). The package also includes Trailer Mode software compatibility (see Trailer Mode).
NOTE: Go to www.tesla.com to purchase accessories for your Model Y. Although third-party products are available, Tesla recommends and supports only Tesla- approved products (see Parts and Accessories). The accessory products available for your Model Y vary based on market region. Before attempting to install a non-Tesla carrier, review the product information to ensure compatibility.
NOTE: When not in use, the ball mount should be removed and stored in a dry location to prevent dust and corrosion. Keep the dust cover over the hitch housing to prevent dirt and debris from entering.
NOTE: Tesla assumes no responsibility for damage or injuries resulting from installing and using an accessory carrier, for any omissions in the instructions accompanying an accessory carrier, or for your failure to follow the instructions. Damage caused by using an accessory carrier is not covered by the warranty.
Carrying Accessories
The hitch receiver is designed to support vertical loads up to 160 lbs (72 kg). When carrying bicycles, skis, or other items on the Model Y hitch, always check to ensure that the maximum weight is not exceeded. When calculating weight, remember to include the weight of the accessory carrier. For example, assuming the carrier weighs 40 lbs (18 kg), the weight threshold is sufficient for carrying two bicycles weighing approximately 60 lbs (27 kg) each, or four items weighing approximately 30 lbs (14 kg) each.
NOTE: Consult the product details of your accessory carrier for more information, such as additional weight or load limits. Damage caused by non Tesla-approved accessories is not covered by the warranty.
CAUTION: Exceeding the maximum weight the Model Y hitch is designed to support (as previously described) can cause significant damage.
CAUTION: Do not attempt to install an accessory carrier on Model Y that is not equipped with the tow package. Doing so can cause significant damage.
