According to the owners manual, there is an adapter, attached to the plastic liner on the Driver's side of the trunk next to the manual drive point. It looks like a hex or flat screw driver head on one end and a nut (13mm?) on the other. The hex end is inserted into manual drive. The manual says to use the spark-plug wrench (like we've seen one of them lately! ) to then turnthis adapter.

I can't confirm all of this by experience, 'cause when i bought the car the motor didn't work, had been RIPPED out (and I MEAN ripped out) and the manual mechanisim installed.

Bottom line, it'll take more than a 13mm wrench, I think.
