Hello! Two questions!

1.) I recently purchased a used '04 XF 6 Speed and I noticed while getting on it from a dead stop the car will take off great but will quickly fall on its face in first gear and again in second gear. Is the car supposed to do this to limit wheel slippage? I turned off the traction control and did it again and got the same results but not as bad.

2.) My previous car was a '04 BMW Z4 and if I held in the traction control button for 10-15 seconds it would completely disable the traction control. Does the XF have the same feature?

Thanks,
Jim
