Important safety notes
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol, for
example. Do not park the vehicle on dry grass- land or harvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb. Parking

Switching off the engine
Important safety notes G
Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking then requires significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.

Vehicle level Important safety notes
Your vehicle regulates its height automati-
cally. All-round self-levelling ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R
normal
R raised: the vehicle is raised by about 25 mm
when compared with the normal level.
R lowered: the vehicle is lowered by about
10 mm when compared with the normal
level.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Comfort tuning"
(Y page 168) and then lock the vehicle
within 60 seconds of the engine being
switched off
R if you have selected "Sports tuning"
(Y page 168) G
Risk of injury
If you have selected "Comfort tuning", the
vehicle will be lowered if you lock it within 60
seconds of the engine being switched off.
Make sure, therefore, that nobody is in the
vicinity of the wheel housing or under the
vehicle when you lock the vehicle. Otherwise,
limbs could become trapped.
! The vehicle is lowered by about 15 mm if:
R you have selected "Comfort tuning"
R you switch off the engine and
R you lock the vehicle within approximately
60 seconds Driving systems
167Driving and parking Z

Make sure when parking that you position
your vehicle so that it does not make con-
tact with the kerb as the vehicle is lowered.
Your vehicle could otherwise be damaged.
Setting the vehicle level
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Your selection remains stored even if you
remove the key from the ignition lock. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped. Setting raised level

Ris
kofa ccident
The reversing camera is only an aid and may
display obstacles in a distorted or incorrect
manner, or may no teven display them at all.
The reversing camera does not relieve you of
the responsibility to pay attention. The cam-
era cannot show objects:
R very near to the rear bumper
R below the rear bumper
R in the area immediately above the boot lid
handle
You are always responsible for safety and
must continue to pay attention to youri mme-
diate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endange ryourself and oth-
ers. G
Risk of accident
Under the following circumstances, the
reversing camera will not function, or function
in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light (the dis-
play may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could otherwise injure others or damage objects and your vehicle
while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Make sure that the "Reversing camera"
function is selected in COMAND APS (see
the separate operating instructions for
COMAND APS).
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND APS display. ATTENTION ASSIST
Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
G
Risk of accident
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others. Driving systems

You can read about how to adjust the bright-
ness of the COMAND APS display in the
COMAND APS operating instructions.
i The infrared headlamps only switch on
when the vehicle is driving at speeds of at
least 10 km/h. This means that you do not have the full visual range while stationary
and cannot check whether Night View
Assist Plus is working.
Pedestrian recognition Night View Assist Plus recognises pedes-
trians using typical characteristics, e.g. a sil-
houette in the shape of a person.
Pedestrian recognition is then switched on
automatically if:
R
Night View Assist Plus is activated.
R you are driving faster than about 10 km/h.
R the surroundings are dark, e.g .when driv-
ing outside built-up areas without street
lighting.
If pedestrian recognition is active, sym-
bol ?appears. If a pedestrian is now recog-
nised, they are framed =and thereby high-
lighted. If the pedestrian recognition system
has brought a pedestrian to your attention,
look through the windscreen to evaluate the
situation. The actual distance to objects and
pedestrians cannot be gauged accurately by
looking at a screen.
It may be the case that objects are highlighted
as well as pedestrians. G
Risk of accident
Pedestrian recognition may be impaired or
inoperative, if:
R pedestrians are partially or completely
obscured by objects, e.g. by parked vehi-
cles.
R the silhouette in the Night View Assist Plus
display is incomplete or interrupted, e.g. by
powerful light reflections.
R pedestrians do not contrast with the sur-
roundings.
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying.

tance range begins at 40 mph. G
Risk of accident
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray.
R there is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R several or no lane markings for a single lane
are present.
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R the distance to the vehicle in front is too
small and the lane markings thus cannot be

G
Risk of accident
Active Blind Spot Assist is only an aid
designed to assist driving .Itis not a substitute
for attentive driving. Automatic braking by the
system may not always be sufficient to avoid
a collision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapty our driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles and/or obstacles, e.g.
crash barriers, in the immediate vicinity of
your vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you brake or accelerate decisively.
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake. R
ESP ®
is deactivated.
R a loss of tyre pressure or a defective tyre
has been detected and displayed.
