wheel is in the uppermost tilt position,
the steering wheel will no longer be
able to move upward when the
easy-entry/exit feature is activated.
If the current seat position falls into a
factory-set position range and the
sytem recognizes the current seat posi-
tion to be rearward enough for easy en-
try and exit, the driver’s seat will not
move to the rear when the
easy-entry/exit feature is activated.
iFor safety reasons, the driver’s seat will
not return to its last set position with
the easy-entry/exit feature activated if
the system recognizes the last set posi-
tion as an extreme forward position. In-
stead, the driver’s seat will remain at or
move to a factory-set maximum for-
ward position. To again fully return the
