Easy-entry/exit feature
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 170).When exiting the vehicle, with the easy-en-
try/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 35) in position 1.
Warning!

trapped or injured by the moving steering
wheel and driver’s seat when the easy-en-
try/exit feature is activated.
To cancel seat/steering wheel movement,

Press seat adjustment switch
(page 38).
Move steering column stalk
(page 40).
Press one of the memory position but-
tons (
page 129).

hicle, or with access to an unlocked vehicle.

feature, which could result in an accident
and/or serious personal injury.
115 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 (
page 35) once
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
(page 129).
