Hello, welcome to JustAnswer
Jaguar technically does not recommend using the supplied floor jack to perform repairs on their vehicles, only in an emergency situation to change a flat tire. I can provide the suggested lift points for you though, You shouldn't work on a vehicle being supported by a jack, you should jack it up and place a jack stand under the vehicle before performing repairs.
HERE is a document showing the lift points for your x-type.
The jacking points will also be used on your xf
I know where to use the supplied
I know where to use the jack that Jaguar supplies. My question was where to use a hydraulic floor jack.
use it at the same lift points, I was merely stating that jaguar does not want you using the jaguar supplied jack to perform any repairs other than emergency tire changes. Additionally, it is not a good idea to use just a floor jack to perform repairs under a vehicle, you would want to jack the vehicle up and place a jack stand under the vehicle to support it while repairs are being performed
