The vehicle is slightly lowered if:
Ryou have selected comfort suspension tun-
ing and
Ryou lock the vehicle within approximately
60 seconds of switching off the engine
You and people in the vicinity of the wheel
arch or the underbody may thus become trap-
ped. There is a risk of injury.

GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
The vehicle may be lowered if you press the
suspension setting selector button or the
AMG button. The vehicle also lowers if it is
stationary.
!If Sport or Sport + suspension tuning has
been selected, the vehicle's ground clear-
ance decreases. Make sure that no objects
become trapped or that the vehicle does
not become damaged, for example, on the
curb.
iThe vehicle level may change visibly at the
rear axle if you park the vehicle and the
outside temperature changes. If the tem-
perature drops, the vehicle level lowers;
with an increase in temperature, the vehi-
cle level rises.
4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP
®, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park- ing space. When maneuvering, parking or
pulling out of a parking space, make sure that

Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on
technical conditions.
iThe rear view camera is protected from
raindrops and dust by means of a flap.
When the rear view camera is activated,
this flap opens.
The flap closes again when:
Ryou have finished the maneuvering proc-
ess
Ryou switch off the engine
Ryou open the trunk
Observe the notes on cleaning
(

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize 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:
Rif the length of the journey is less than
approximately 30 minutes
Rif the road condition is poor, e.g. if the sur- face is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
Rif you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h)
Rif you are driving with the DISTRONIC PLUS
Steering Assist activated
Rif the time has been set incorrectly
Rin active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue 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

XSelect the Assistance display for ATTEN-
TION ASSIST using the on-board computer
(
Ypage 190).
The following information is displayed:
Rlength of the journey since the last break.
Rthe attention level determined by ATTEN-
TION ASSIST, displayed in a bar display in
five levels from high to low.
Rif ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System Suspended
message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST
XActivate ATTENTION ASSIST using the on-
board computer (
Ypage 190).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
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
À symbol and OFF appear in the multi-
function display in the assistance display
when the engine is running.
When ATTENTION ASSIST has been deactiva-
ted, it is automatically reactivated after the
engine has been stopped. The sensitivity
selected corresponds to the last selection
activated (standard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist:
Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
XIf necessary, take a break.
XConfirm the message by pressing the a
button on the steering wheel.
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. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum
speed permitted to the driver in the instru-
ment cluster. The data and general traffic reg-
ulations stored in the navigation system are
used to determine the current speed limit.
As Traffic Sign Assist is a map-based system,
traffic signs put up temporarily (e.g. near
roadworks) are not detected.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits is
updated.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are
also shown.
The traffic signs are only displayed with the
restrictions if:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the

Warning and indicator lamps in the instrument cluster
General notes
This section describes indicator and warning lamps in the instrument cluster relevant to safety
and solutions. A description of other indicator and warning lamps in the instrument cluster and
their solutions can be found in the Digital Operator's Manual.
Some systems carry out a self-diagnosis when the ignition is switched on. Therefore, some
indicator and warning lamps may light up or flash temporarily. This behavior is non-critical.
These indicator and warning lamps only indicate a malfunction if they light up or flash after
starting the engine or whilst driving.
