Give four bolts of fastening of guides of a seat to the bottom and remove a seat from the car. On some models, perhaps, it is necessary to disconnect conducting of heating of seats; it is also possible that it is necessary to remove a seat belt from a seat.
You make installation upside-down. Reliably tighten fixing bolts.
Pillows of a back seat
At first give two fixing bolts if they are available. Take strong forward (Sedan/cabriolet models) or a back (Tourist / Station wagon model) part of a pillow and sharply pull up.
