If this is not the case, repeatthe steps
above again.
Problems with the side windows
GWARNING
If you close a side window again immediately
after it has been blocked or reset, the side
window closes with increased or maximum
force. The reversing feature is then not active.
Parts of the body could be trapped in the
closing area in the process. This poses an
increased risk of injury or even fatal injury.
Make sure that no parts of the body are in the
closing area. To stop the closing process,
release the switch or push the switch again to
reopen the side window.
Problem:aside window cannot be closed
because it is blocked by objects, e.g.
leaves in the window guide.
XRemove the objects.
XClose the side window.
Problem:aside window cannot be closed

window is obstructed during closing and
reopens again slightly:
XImmediately afterthe window blocks, pull
the corresponding switch again until the
side window has closed.
The side window is closed with increased
force.
If a side window is obstructed again during
closing and reopens again slightly:
XImmediately after the window blocks, pull

Panoramaroof with power tilt/sliding
panel
Important safety notes
In the following section, the term "sliding
sunroof" refers to the panorama roofwith
power tilt/sliding panel.
GWARNING
While opening and closing the sliding sunroof,
body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity during the opening and closing
procedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be
stopped.
GWARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are
left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
At high speeds the raised sliding sunroof
automatically lowers slightly at the rear. This
could trap you or other persons. There is a risk
of injury. Make sure that nobody reaches into

vehicle is in motion.
If somebody becomes trapped, reduce speed
immediately, paying attention to road and
traffic conditions.The sliding sunroof opens
again to its original position.
If the sliding sunroof is not completely raised,
you can then raise it further with the switch.
!Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
!The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.
iResonance noises can occur in addition
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises.
Sliding sunroof reversing feature
The sliding sunroof is equipped with an
automatic reversing feature. If a solid object
blocks or restricts the sliding sunroof during
the closing process, the sliding sunroof opens
again automatically.However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing the sliding sunroof.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small
fingers
Rover the last 1/6 in(4 mm) of the closing
movement
Rduring resetting
Rwhen closing the sliding sunroof again
manually immediately after automatic
reversing
This means that the reversing feature cannot
prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction

Apart from driving style, consumption is
dependent on many factors such as, e.g.:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumers switched on
These factors are not taken into
considerationby the ECO display.
The evaluation of your driving style is carried
out using the following three categories:
RAcceleration(evaluation of all
acceleration processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessmentofdriving behavior
at all times):
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes):
-The bar fills up: anticipatory driving,
keeping yourdistance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
-The bar empties: frequent braking
iAn economical driving style specially
requires driving at moderate engine
speeds.
To achieve a higher value in the categories
AccelerationandConstant:
Robserve the gearshift recommendations.
Rdrive in drive programE.
iOn long journeys at a constant speed, e.g.
on the highway, only the bar forConstant
will change.
iThe ECO display summaries the driving
characteristics fromthe start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry out a manual reset.
Further information on the ECO display
(Ypage 198).
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you
to take advantage of the engine's braking
effect.For this, you need to have selected
manual drive programM.This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benzwarranty.
iBriefly depressing the acceleratorpedal
on downhill gradients while the manual
drive programMis temporarily activated:
the automatic transmission may switch to
the last active automatic drive programE
orS.The automatic transmission may shift
to a higher gear. This can reduce the
engine's braking effect.

message appears in the multifunction
display.
XIf necessary, take a break.
XPress theorbutton to confirm
the message.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
preconditionfor this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness again if:
Ryou switch off the engine.
Ryou take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break.
When ATTENTION ASSIST is deactivated, the
symbol appears in the multifunction
display in the assistance graphic display.
Speed Limit Assist
General notes
Speed Limit Assist shows you detected speed
limits in the multifunction display.Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does notdetectany traffic
signs, the speed limit from the digital road
map is used and shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windshield.
Speed Limit Assist camera
Important safety notes
Speed Limit Assist is only an aid and does not
always detect traffic signs with information
aboutthe maximum permissible speed.
Traffic signs always have priority over the
Speed Limit Assist display.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthere is glare, e.g. from the sun or from
oncoming traffic
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
Rthe traffic signs are covered, for instance
by dirt, snow or trees
Rthe traffic signs are poorly illuminated
Rthere are ambiguous traffic signs, for
instance near roadworks or on multi-lane
