So I have a 2002 v70 cross country. I am trying to figure out if I have the 3rd row seat. I do not have the manual, it didn't come with the car. How am I able to see if I have that?

 

do you see extra seat belts going from the columns into the floor for the third row? Did you try lifting up the floor in the rear (the seat folds up and faces rearward)? The seat is a bolt in option and can be added or removed as needed.

 

Lift the floor board to access the spare then try lifting the floor board immediately rearward.

That is the seat back of the 3rd seat
