If indicator lamp :lights up, PARKTRONIC is
deactivated. Parking Guidance is also deacti-
vated.
i PARKTRONIC is automatically activated
when you turn the key to position 2in the
ignition lock.
Trailer towing* PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
!
Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Parking Guidance*
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 157). G
Risk of accident
Parking Guidance is merely an aid and may
recommend parking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitable surfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.
In some circumstances, Parking Guidance
might therefore issue steering instructions
too soon. This may lead to a collision. For this
reason, you should avoid using Parking Guid-
ance in such situations. Driving systems

Trailer towing* For vehicles with a trailer coupling, the mini-
mum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use Parking Guidance. When
the electrical connection is established

Guidance ceases to be available. PARK-
TRONIC is deactivated for the rear area. Reversing camera*
The reversing camera is an optical aid. It
shows the area behind your vehicle in the
COMAND APS display. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured. The reversing camera is located in the handle
strip of the boot lid/tailgate.
Example: Saloon
:

View through the camera The area behind the vehicle is displayed in a
mirrored fashion, as in the rear-view mirror.
G
Risk of accident
The reversing camera is only an aid and may
display obstacles in a distorted or incorrect
manner, or may not even 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/tailgate handle recess
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endanger yourself and oth-
ers. G

ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests 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 a substitute
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 accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
R personal driving style, e.g. steering charac-
teristics
R driving conditions, e. g. time, driving time
ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:
R if the road condition is poor, e.g. large
bumps or potholes
R there is a strong side wind
R you have adopted a very sporty driving style
with high cornering speeds or driving with
a high rate of acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently operating or making a
call using COMAND APS*
R in active driving situations, for example, if
you are changing lanes or changing the
vehicle speed Driving systems

In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road. A
camera at the top of the windscreen picks up
the infrared light and displays a black and
white image in the COMAND APS display. The
image displayed in COMAND APS corre-
sponds to a road lit up by main-beam head-
lamps. This enables you to see the road's
course and any obstacles in good time. If
pedestrian recognition is activated, pedes-
trians recognised by the system are highligh-
ted in the Night View Assist Plus display. G
Risk of accident
Night View Assist Plus is only an aid designed
to assist driving and does not relieve you of
the responsibility to pay attention. Continue
to look through the windscreen instead of
relying on the Night View Assist Plus display.

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 The Night View Assist Plus recognises pedes-
trians using typical characteristics, i. e. a sil-
houette in the shape of a person.
Pedestrian recognition is activated, 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 i
Animals are not recognised by pedestrian
recognition.
Misted up or dirty windscreen If the windscreen in front of the camera is
misted up or dirty on the inside or outside, the
Night View Assist Plus display is affected.
X To demist: check the automatic air-condi-
tioning settings (Y page 179) and fold
down the camera cover (Y page 245).
X To demist the inside of the wind-
screen: fold down the camera cover and
clean the windscreen (Y page 242). Lane package*
The lane package consists of Blind Spot
Assist and Lane Keeping Assist.
Blind Spot Assist Blind Spot Assist uses a radar sensor system
to monitor the area on both sides of your
vehicle. It supports you when you change
lanes at speeds above 30 km/h. In each case,
a warning lamp appears in the exterior mirror
as soon as a vehicle is detected in the area
monitored. When you switch on the corre-
sponding turn signal prior to changing lanes,
you receive an optical and acoustic collision
warning. For this purpose, Blind Spot Assist
uses sensors in the rear bumper.
G
Risk of accident
Blind Spot Assist is only an aid and may not
detect all vehicles. Blind Spot Assist does not
relieve you of the responsibility of paying
attention.
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.
The radar sensor system is automatically
deactivated near radio telescope facilities

When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow up to a speed
of 30 km/h. At speeds above 30 km/h, the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always issued when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
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.

(Y page 131), Lane Keeping Assist is activa-
ted starting at a speed of 60 km/h. If the
miles display unit is selected, the assistance
range begins at between 35 and 40 mph.
Lane Keeping Assist is designed to detect
lane markings on the road and warn you
before you leave your lane unintentionally.
Usually the warning is given when a front
wheel passes over a lane marking. It will warn
you by means of intermittent vibration in the
steering wheel for up to 1.5 seconds. Driving systems

dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correct the pressure as nec-
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres-
sure can be checked in the on-board com-
puter. G
Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Risk of accident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz is fitted on the tyre
valve.
Tyre pressures that are too low have a nega-
tive effect on vehicle safety, which could lead
to your causing an accident.
If possible, you should only correct tyre pres-
sures when the tyres are cold. Depending on
the ambient temperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions. Driving with tyre pressure that is too high or
too low can:
R
shorten the service life of the tyres
R increase the likelihood of tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
Also check the pressure of the "Minispare"
emergency spare wheel*. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
Speeds up to 210 km/h:
Despite the values stated on the tyre pressure
information label (fuel filler flap), for speeds
up to 210 km/h andwith 16" or 17" tyres,
the values stated can be reduced as follows,
without a reduction in safety:
Saloon: -0.3 bar / (-4 psi)
Estate: -0.2 bar (-3 psi)
This does not apply to vehicles towing a
trailer.
This improves the ride comfort of your vehi-
cle; however, the fuel consumption may
increase slightly. Tyre pressure loss warning
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play. G
Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected. 226
