For information on additional convenience
features permitting easy entry and exit,
see “Easy-entry/exit feature”
(
page 344).
Warning!G
The seat belts provide protection only with
the backrest locked in place. Therefore, the
backrest must be locked in place with the
vehicle in motion. Do not drive the vehicle
when the backrest is not locked in place.
If the warning message:
Seat backrest,
Front Right
not locked
or
Seat backrest,
Front Left
not locked
is displayed in the multifunction display,
then the respective backrest is not engaged
in its lock. Carefully slow down, and drive
with caution to an area which is in a safe dis-
tance from the roadway. Always provide suf-
ficient room behind the backrest and fold
the backrest all the way back until it locks in
place.
The warning message is no longer displayed
as soon as the backrest is locked in place. If
both backrests are locked in place and the
warning message is still displayed, have the
system checked at an authorized
Mercedes-Benz Center immediately.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment pro-
cedure.!The automatic seat slide is provided with a
safety feature.
The automatic process is interrupted if the back-
rest of the sliding seat is pushed against an oc-
cupant or object. The seat will slide forward and
stop.
Investigate and correct the cause of interruption.
Now use memory button (
page 358) or seat
adjustment switch (
page 340) to bring the
seat into the desired position.
When folding the backrest forward from a re-
clined position, and then folding it back, the
backrest stops in a more upright position for the
safety of any rear-seat passenger. Adjust the
backrest until your arms are slightly angled when
holding the steering wheel (
page 340).

Easy-entry/exit feature
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the driver’s seat is in its
maximum rearward position and the steer-
ing wheel is in its uppermost position.
The easy-entry/exit feature can be activat-
ed or deactivated in the “Vehicle” menu of
the COMAND system (
page 239).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 337) once
with the driver’s door closed
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel and driver’s seat when the easy-en-
try/exit feature is activated.
To stop seat/steering wheel movement, do
one of the following:
Press seat adjustment switch
(
page 340).
Move steering wheel adjustment stalk
(
page 351).
Press one of the memory position but-
tons or the memory button M
(
page 358).
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
!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.

With 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 position 0
or 1 or the KEYLESS-GO* start/stop
button (
page 337) in position 1
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 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 358).
iThe last set driver’s seat and steering wheel
positions are stored when
the ignition is switched off (page 336)
the position is stored in memory
(
page 357)
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.
