In case of improper operation of the electric backrest adjusting mechanism or excessive backrest flex, the seat back gearbox cables may have become disconnected at the gearbox. To repair this situation, the following procedure should be applied:
1. Remove seat and take off backrest.
2. Loosen backrest trim panel partially.
3. Shorten flexible shaft housing on gearbox end by 5 mm.
4. Secure housing to gearbox with suitable hose clamp.
When assembling, the square rod is slid into the eccentric pin on the seat and through the gearbox. (Don't knock in with a hammer) Then tighten the backrest bolts finger tight, tighten bolts on the square rods and then tighten backrest bolts completely.
The alignment marks (e) on the outside are important when assembling the seat frame and seat backrest. They must align with each other. Marks may be either painted or stamped in the metal.
