129 Controls in detailSeats
When entering the vehicle, with the
easy-entry/exit feature activated, the
steering wheel or, depending on your se-
lection, the steering wheel and driver’s
seat will return to their last set memory po-
sition or a factory-set maximum forward
position when you:
close the driver’s door with the ignition
switched on
insert the SmartKey into the starter
switch or press the KEYLESS-GO*
start/stop button (

with the driver’s door closed.
iIf the current position for the steering
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 sys-
tem recognizes the current seat posi-
tion to be rearward enough for easy
entry 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
driver’s seat to your last set position or
to memory position, adjust the seat to
the desired position or press and hold
the respective memory position button
