This feature allows for easier entry into and
exit from the vehicle.
The easy-entry/exit feature can be activat-
ed or deactivated in the
Convenience
sub-
menu of the control system (
page 175).When exiting the vehicle, with the
easy-entry/exit feature activated and
depending on your selection, the steering
wheel tilts upwards and/or the driver’s
seat moves a few inches to the rear when
you:
remove the SmartKey from the starter
switch,
or
open the driver’s door with the
SmartKey in starter switch position 0
or 1 or the KEYLESS-GO* start/stop
button (
page 36) in position 1.

125 Controls in detailSeats
When entering the vehicle, with the
easy-entry/exit feature activated, the
steering wheel or, depending on your
selection, the steering wheel and driver’s
seat will return to their last set position or
a factory-set maximum forward position
when you:
close the driver’s door, and switch on
the ignition.
or
insert the SmartKey into the starter
switch or press KEYLESS-GO*
start/stop button once with 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.
Instead, the driver’s seat will remain at
or move to a factory-set maximum
forward position. To again fully return
the driver’s seat to your last set posi-
tion or to memory position, adjust the
seat to the desired position or press
and hold the respective memory
position switch (
page 139).
