WINDOWS

DESCRIPTION AND OPERATION

86-6-9

Convenience opening begins after a time delay of 2.5 seconds when the door lock is held in the unlock position or the 
remote handset unlock button is pressed and held. The opening operation stops immediately the door lock is released 
from the unlock position or the remote handset unlock button is released. The window motors are switched in pairs, 
with the front ones switched first followed 1 second later by the rear ones. The sunroof begins opening 3.5 seconds 
after convenience opening started.

Operating the windows and sunroof in sequence allows a degree of selective operation, e.g. the windows can be 
closed and the sunroof left open when locking the vehicle and using convenience closing.

Repetition Blocking
To prevent the window motors from overheating, the door modules and the BCU record the run time for each motor 
they control. The run time, in seconds, is added to a counter on completion of each activation, and one second is 
deducted from the counter for every three seconds the window motor is inactive. If the counter exceeds 60 seconds, 
no new activation for the window motor is accepted until the counter is below 60 seconds again. The only exception 
is a reversing operation triggered by the anti-trap function, which is always accepted regardless of the counter value.
