Question

specified on a sticker, located on the lifting arm. never exceed the maximum load cap jack. prevent the vehicle from rolling. this can be achieved by applying the parking brake or chocks behind the wheels that are not being lifted. always work on firm, level flooring (preferably concrete). keep the ground and the car from dropping off the jack. the shop floor should be clean, free of debris, that could keep the wheels from rolling freely. the jack support cup should be positioned under a solid point on the car body or chassis. often the car manufacturer specifies designated lifting points. these lifting points are shown in the corresponding service information and/or vehicle owners manual. positioning the jack at a non - designated lift point is dangerous and could cause damage to the vehicle. note: some vehicles are designed with lift points that require a special adapter to be used in conjunction with the floor jack. what can you do, if you dont know where to place the floor jack support cup? jack up the vehicle slowly and watch for how the lifting point is keeping its shape. feel for a possible lifting point with your hand. consult the vehicle service information or owners manual.

Explanation:

The text clearly states that car manufacturers often specify designated lifting points in the service information and/or vehicle owner's manual. So, when unsure of where to place the floor - jack support cup, consulting these sources is the correct action.

Answer:

Consult the vehicle service information or owner's manual.
