358 Controls in detail
Seats
With the easy-entry/exit feature activated,
the steering wheel and driver’s seat will re-
turn to their last set memory position 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 346) once
with the driver’s door closedWith the easy-entry/exit feature activated
the steering wheel tilts upwards and 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 position0
or1 or the KEYLESS-GO* start/stop
button (
page 346) in position1
!Do not activate the easy-entry/exit feature
if the seat backrest is in an excessively reclined
position. Doing so could cause damage to front
or rear seats.
First move the seat backrest to an upright posi-
tion.
iFor safety reasons, the driver’s seat will not
return to its last set position with the easy-en-
try/exit feature activated if the system recogniz-
es the last set position as an extreme forward
position. Instead, the driver’s seat will remain at
or move to a factory-set maximum forward posi-
tion. To again fully return the driver’s seat toyour last set position or to memory position, ad-
just the seat to the desired position or press and
hold the respective memory position button
(
page 366).
iThe last set driver’s seat and steering wheel
positions are stored when

the ignition is switched off (page 344)

the position is stored in memory
(
page 365)
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 system recognizes the
current seat position to be rearward enough for
easy entry and exit, the driver’s seat will not
move to the rear when the easy-entry/ exit fea-
ture is activated.
The adjustment procedure is briefly interrupted
when the engine is started.
Warning!G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All driver’s seat and steering wheel ad-
justments must be completed before setting
the vehicle in motion. Driving off with the
driver’s seat/steering wheel still adjusting
could cause the driver to lose control of the
vehicle.
