Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. You receive steering
instructions when parking. You may also use
PARKTRONIC ( Y page 307).
GWarning
Parking Guidance is merely an aid and may
display parking spaces that are not suitable
for parking, for example:
R no-parking areas
R parking spaces with unsuitable surfaces
(road surface)
R driveways
R entrances and exits
Parking Guidance detects and measures
potential parking spaces while driving past.
Changes to the parking space after this point
are not taken into account, for example if the
vehicle in front of or behind the parking space
changes position or objects in the parking
space are moved.
Even when using Parking Guidance, you are
still responsible for driving carefully. If you
rely on Parking Guidance alone, you could
cause an accident and injure yourself and
others.
Safety always remains your responsibility and
you must continue paying careful attention to
your immediate surroundings when parking
and maneuvering.310Driving systemsDriving and parking

GWarning!
The system cannot detect objects located
above the area that the sensors scan. These
objects, e.g. protruding load, overhang, or
truck tail lifts, will be ignored when computing
the parking procedure. The Parking Guidance
might therefore provide untimely steering
instructions. This could cause a collision.
Thus, do not use the Parking Guidance in such
situations.
GWarning!
Make sure no persons or animals are in the
area in which you are maneuvering. You could
otherwise injure them.
! Pay particular attention to low objects or
objects with flat surfaces, such as trailer
drawbars, posts, cross beams and curbs.
These types of objects cannot be detected
by Parking Guidance and may damage the
vehicle.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
Rthat are parallel to the direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC warning
messages during the parking procedure
(Y page 308).
RWhen transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
RNever use Parking Guidance with snow
chains or an emergency spare wheel
installed.
RMake sure that the tire pressures are
always correct. This has a direct effect on
the steering instructions.
RThe way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Parking
Guidance may guide you too far or not far
enough into a parking space. In some
cases, it may also lead you across or onto
the curb. If necessary, cancel the parking
procedure with Parking Guidance.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
Detecting a parking space
:Detected parking space on the left;Parking symbol=Detected parking space on the right
Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
At speeds below 19 mph (30 km/h), you see
white parking symbol ; in the instrument
cluster as a status indicator. Parking
Guidance only shows parking spaces on the
passenger side in the default setting. Parking
spaces on the driver's side are displayed as
Driving systems311Driving and parkingZ

soon as the turn signal on the driver's side is
activated. To park on the driver's side, you
must leave the driver's side turn signal
switched on until you have engaged reverse
gear. If a parking space is detected, parking
symbol ; changes to blue. Additionally, an
arrow pointing right = or left : is shown.
Parking Guidance will only detect parking
spaces:
Rthat are closed in at the back
Rthat are parallel to the direction of travel
Rthat are at least 5 ft (1.5 m) wide
Rthat are at least 4.3 ft (1.3 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.
Parking
The following instructions refer to parking in
a space on the front-passenger side. To park
in a space on the driver's side, mirror the
instructions.
GWarning!
The Parking Guidance is only an aid and may
not detect all obstacles. The Parking
Guidance does not relieve you of the
responsibility to pay attention. You are always
responsible for safety and must continue to
pay attention to your immediate surroundings
when parking and maneuvering. Otherwise,
you could endanger yourself and others.

Guide lines in the COMAND display
GWarning!
Use of rear view camera can be dangerous if
you are color-blind or have impaired color
vision.
Only use rear view camera if you can see and
distinguish all colored guidelines shown by
rear view camera on the COMAND system
display.
GWarning
Please note that objects that do not touch the
ground may appear to be further away than
they actually are, for example:
Rthe bumper of a vehicle parked behind you
Rthe trailer drawbar
Rthe ball coupling of a trailer tow hitch
Rthe rear end of a truck
Ra slanted post
In such cases, you should not use the guide
lines to judge the distance. You may misjudge
the distance, which increases the risk of
impacting the objects.
Even if the object you approach is directly on
the ground, do not approach the object any
closer than the red guide line.
Guide lines ; and = show the approximate
distance to the rear area. Yellow guide
line ; indicates a distance of approximately
3 ft (1 m) and red guide line = indicates a
distance of approximately 10 in (0.25 m). The
distances only apply to objects at ground
level. Blue guide line : depicts the width
required for the vehicle. It is used to align the
vehicle with the edge of the road, e.g. the
curb.
ATTENTION ASSIST
Important safety guidelines
ATTENTION ASSIST helps you during long,
monotonous journeys such as on highways
and trunk roads. It is active in the range
between 50 mph (80 km/h) and 112 mph
(180 km/h).
If ATTENTION ASSIST detects fatigue or
increasing lapses in concentration on the part
of the driver, it suggests you take a break.
GWarning!
The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
Driving systems315Driving and parkingZ

recognize dangers too late which could result
in an accident and serious injury to you and/
or others.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
Ryour personal driving style, e.g. steering
characteristics
Rdriving conditions, e.g. time, driving time
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the road condition is poor, e.g. if the
surface 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 slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
Rif you are currently operating or making a
call using COMAND
Rif the time has been set incorrectly
Rin active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display
XActivate ATTENTION ASSIST using the on-
board computer (Y page 340).
Symbol : appears in the multifunction
display.
If ATTENTION ASSIST is active, it will not warn
you until at least 20 minutes after your
journey has begun. You then hear an
intermittent warning tone twice and the
Attention Assist Time for a break?
message appears in the multifunction
display.
XIf necessary, take a break.XPress a 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 and ATTENTION ASSIST
still detects fatigue or increasing lapses in
concentration, you will be warned again after
15 minutes at the earliest.
ATTENTION ASSIST is reset when you
continue your journey, and it 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.
Night View Assist Plus
Important safety notes
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 windshield picks up
the infrared light and displays a black-and-
white image in the multifunction display. The
image shown in the multifunction display
corresponds to a road lit up by high-beam
headlamps. This enables you to see the road's
course and any obstacles in good time. If
pedestrian recognition is activated,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
GWarning
Night View Assist Plus is only an aid designed
to assist driving. It is not a substitute for
attentive driving. Do not rely solely on the
Night View Assist Plus display. Continue to
look through the windshield. You are
responsible for safety and must drive in
316Driving systemsDriving and parking

accordance with traffic conditions. You could
otherwise put yourself and others in danger.
The system may be impaired or unavailable if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or heavy spray.
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
Ryou are driving on bends, uphill gradients
or downhill gradients.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display. This
is also the case if you cannot switch on the
high-beam headlamps because of oncoming
traffic.
GWarning!
The Night View Assist Plus cannot record
objects immediately in front of or next to the
vehicle. When maneuvering, continue to look
through the windshield. Make sure no
persons or animals are in the area in which
you are maneuvering. You could otherwise
injure them.
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming
traffic.

display. This line is no longer available for
basic menus. You have to deactivate Night
View Assist Plus if you wish to change a
setting using the buttons on the multifunction
steering wheel.
Pedestrian recognition
The Night View Assist Plus recognizes
pedestrians using typical characteristics, i.e.
a silhouette in the shape of a person.
Pedestrian recognition is then switched on
automatically if:
RNight View Assist Plus is activated.
Ryou are driving above
approximately 6 mph (10 km/h).
Rthe surroundings are dark, e.g. when
driving outside built-up areas without
street lighting.
If pedestrian recognition is active,
symbol ? appears. If a pedestrian is now
recognized, they are framed = and thereby
highlighted. If the pedestrian recognition
system has brought a pedestrian to your
attention, look through the windshield 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.
GWarning!
The pedestrian detection may be impaired or
unavailable when
Rpedestrians are obstructed fully or in part
by other objects such as parking vehicles
Rthe silhouette in the Night View Assist Plus
image is displayed incomplete or
interrupted, e.g. by significant light
reflection

Fogged up or dirty windshield
If the windshield in front of the camera is
fogged up or dirty on the inside or outside, the
Night View Assist Plus display is affected.
GWarning!
Please do not forget that your primary
responsibility is to drive the vehicle. A driver's
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, stop before trying to
remove window fogging or cleaning the
windshield in front of the Night View Assist
Plus camera.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
