On the right-hand side of the vehicle, the towing eye is screwed into a threaded socket behind a cover located on the front and rear bumpers.
Important
Be sure to read about towing and its limitations before you start.
Fetch the towing eye so you have it at hand.
Attach in the front

Push on the side of the cover to make it pivot. The cover can then be removed.
Attach in the rear

To attach in the rear: remove the cover by pushing in the center of its right side. The cover loosens and can then be removed.
Screw the towing eye all the way into the socket.
Important
It is important to screw the towing eye firmly into place. Putting something through the towing eye, such as a lug wrench, can provide extra leverage.
After you're done, remember to remove the towing eye and return it to its storage location. Make sure to put the cover back in place to protect the outlet.
