Instructions for removing lug nuts with round notches:
1. Park your vehicle on a level surface and apply the parking brake.
2. Chock the wheels that are not being removed to prevent the vehicle from rolling.
3. Use a jack to raise the vehicle off the ground so that the tire you want to remove is in the air.
4. Use the spline lug wrench or locking lug nut key to loosen the lug nuts, turning counterclockwise. Do not remove the lug nuts completely at this point.
5. Lower the vehicle until the tire is just touching the ground, but not supporting the full weight of the vehicle.
6. Finish removing the lug nuts and take off the wheel.
7. Repeat steps 4-6 for the remaining lug nuts and wheels.
