assuming it is the folding up of the wingmirrors, there a 2 ways to fold them,
1, turn the mirror adjustment knob into the folded position, they fold up, but your manually having to fold them down again when ready.
2, and my favorite method, press and hold the lock button on the keyfob when exiting the car, all windows will do up if open and the mirrors fold in, then when you next enter the car and turn the ignition on, the mirrors will fold back down again.
If the keyfob method dosent work, i think someone round here got the dealer to make a ecu change to enable it, as long as your mirrors are motorised im sure they can amend ecu. thers a thread round here somewhere about it.
