Can I drive my Xantia with ride height at minimum?

Hi all, the rear height unit has seized on my Xantia thus snapping the linkage rod so ride height is non moveable on thr rear and at present is sat very low indeed, when started, the front will raise to selected height, what I would like to know is, will the car be ok to drive (few hours max) with the minimum ride height selected (so both front and rear look level)?
