WARNING
At high speeds the raised sliding sunroof auto- matically lowers slightly at the rear. This could
trap you or other persons. There is a risk of
injury. Make sure that nobody reaches into
the sweep of the sliding sunroof whilst the
vehicle is in motion.
If somebody becomes trapped, immediately
pull back the sliding sunroof switch. The slid- ing sunroof lifts during opening.
! Only open the panorama sliding sunroof if it
is free of snow and ice. Otherwise, malfunc-
tions may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be damaged.
i Resonance noises can occur in addition to
the usual airflow noises when the sliding sun-
roof is open. They are caused by minor pres-
sure fluctuations in the vehicle interior.
Change the position of the sliding sunroof or
open a side window slightly to reduce or elim-
inate these noises. Reversing feature of the sliding sun-
roof
In the following section, the term "sliding sun-
roof" refers to the panorama sliding sunroof.
The sliding sunroof is equipped with an auto-
matic reversing feature. If an object blocks or
restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. The automatic reversing feature is,
however, only an aid and is no substitute for your
attention when closing the sliding roof. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 4 mm of the closing movement
R during resetting
R when closing the sliding sunroof again man-
ually immediately after automatic reversing This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R release the switch immediately or
R press the switch in any direction during the
automatic closing process

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of the
acceleration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds
R the outer area empties and the
inner area is grey: sporty acceler-
ation ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus from start
Bonus from start does not
indicate a fixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation.
R drive the vehicle in drive program Cor E
(vehicles with DYNAMIC SELECT button).
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During
a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 204).

Important safety notes G
WARNING
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.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. For vehicles with
automatic transmission, you need to activate
manual gearshifting beforehand (Y page 150).160
Driving tipsDriving and parking

Select this view when you are driving out of an
exit and the view of crossing traffic is restricted,
for example. ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all in the following situations:
R the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in case of strong side winds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing your tiredness again when you continue your
journey if:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break Displaying the attention level

display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h.
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 209).
The system determines the attention level of
the driver depending on the setting selected:
Standard Standard selected: the sensitivity with which
the system determines the attention level is set to normal.
Sensitive Sensitive selected: the sensitivity is set
higher. The attention level detected by ATTEN-
TION ASSIST is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been switched off. The sensitivity selected Driving systems
