We will go ahead and move this spare tire out of the way for now that will allow us to find the jack point on this vehicle. Most jack points are right here in this area.

It is also important to make sure that the jack lift head is also securely positioned as well. What we will do now is take the lug nut wrench and loosen the plastic lug nut caps. After loosening the plastic lug nut caps, we will be able to remove the hubcap. By taking the lug nut wrench and carefully prying it off. With the hubcap removed, we can now take the lug nut wrench and loosen lug nuts.

If the tire is elevated, the tire would spin and therefore, would not be able to have the necessary torque to take the lug nut off. We will go ahead and rotate to counter clockwise and loosen all of the lug nuts. With the lug nuts now loosened, we can now go ahead and elevate the car to about this level which will allow us to pull the tire off. "
