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
position.

For safety reasons, the driver’s seat will
not return to its last set position if the
system recognizes 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 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 (Y page 274).
i The last set driver’s seat and steering
wheel positions are stored when the
ignition is switched off and the position is
stored in memory.
i If the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will not move.
If the current seat position is within 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.
The adjustment procedure is interrupted
briefly when the engine is started. G
Warning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All driver’s seat and steering wheel
adjustments 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.
Crash-responsive exit aid When you open the driver’s door after an
accident has occurred, the steering column
moves
up.
The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
occupants. The crash-responsive exit aid can only be
triggered
when
the easy-entry/exit feature is
activated via the control system. Rear seat head restraints
G
Warning!
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the
area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints. G
Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust the
head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident. G
Warning!
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise their
protective function cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.
Folding rear seat head restraints back The rear seat head restraints can be folded
backward for increased visibility.268

Notes
i If you drive in countries with left-hand
driving, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized Mercedes-Benz Center.
i The active Bi-Xenon headlamps increase
usable illumination over conventional
headlamps because they follow the
curvature of the road ahead. The beams of
the active Bi-Xenon headlamps shift to
either side according to the vehicle’s
steering angle and speed. 274

Opening and closing
The windows are opened and closed
electrically. The switches for all windows are
located on
the driver’s door. The switches for
the respective windows are located on the
passenger door and the rear side trim panels.
i Operating the rear side windows from the
rear is not possible when you activate the
override switch ( Y page 55). G
Observe Safety notes, see page 51. G
Warning!
When opening or closing the windows, make
sure there is no danger of anyone being
harmed by the opening/closing procedure.
The door windows are equipped with the
express operation and automatic reversal
function. If
in express operation mode a door
window encounters an obstruction that
blocks its path, the automatic reversal
function will stop the door window and open
it slightly. The windows operate differently when the
switch is pulled and held. See the “Closing
when a window is blocked” section in this
chapter for details.
The closing of the door windows can be
immediately
halted
by releasing the switch or,
if the switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The closing of the rear side windows can be
immediately halted by releasing the switch.
Activate the override switch when children
are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the window
opening. G
Warning!
Do not keep any part of your body up against
the window
pane when opening a window. The
downward motion of the pane may pull that
part of your body down between the window
pane and the door frame and trap it there. If
there is a risk of entrapment, release the
switch and pull it to close the window.
i You can also open or close the windows
using the SmartKey, see “Summer opening
feature” ( Y page 283) and “Convenience
closing feature” ( Y page 284).
i After switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the windows until
you open a door. If no door was opened you
can operate the windows for up to
5 minutes. 282

Use a gentle dishwashing detergent or mild
detergent for
delicate fabrics as a washing
solution.
X Wipe with a cloth moistened in a lukewarm
solution.
The surface
may temporarily change color.
If this is the case, wait for it to dry. G
Warning!
Do not use cleaners or cockpit care sprays
containing solvents
to clean the cockpit or the
steering wheel. Cleaners containing solvents
will make the surface porous and vehicle
occupants could suffer serious injuries from
plastic parts coming loose in the event of air
bag deployment.
! Do not use oil, wax or scouring agents.
Otherwise you may scratch or damage the
surface.
Hard plastic trim items
X Use Mercedes-Benz approved Interior Care
on a
soft, lint-free cloth and apply with light
pressure.

severely weaken them. In a crash they may
not be able to provide adequate protection.
Upholstery Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause the
upholstery to become permanently
discolored. By lining the seats with a proper
intermediate
cover,
contact-discoloration will
be prevented. G
Warning!

and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
