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

Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering.
Activating the rear view camera
XMake sure that the SmartKey is in
position 2 in the ignition lock.
XEngage reverse gear.
The area behind the vehicle is shown in the
COMAND display with guide lines.
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

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.
:Night View Assist cameraSwitching on Night View Assist Plus
You can only activate Night View Assist Plus
if:
Rthe SmartKey is in position 2 in the ignition
lock.
Rit is dark.
Rthe light switch is in the c or L
position.
Rreverse gear has not been engaged.
XPush rocker switch : up.
The Night View Assist Plus display appears
in the multifunction display.

and apply the brakes. Active Blind Spot Assist
does not detect all traffic situations and road
users. Always make sure that there is
sufficient distance to the side for other traffic
or obstacles. An inappropriate brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate.
You are responsible for the vehicle's speed,
braking in good time, and steering correctly.
Always adapt your driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize 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:
Rthere are other vehicles and/or obstacles,
such as crash barriers, close to the vehicle.
Ra vehicle approaches you too closely at the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.
Ryou brake or accelerate decisively.
Ra driving safety system intervenes, e.g.
ESP® or PRE-SAFE® Brake.
RESP® is deactivated.
Ra loss of tire pressure or a defective tire has
been detected and displayed
Activating Active Blind Spot Assist
XMake sure that the radar sensor system
(Y page 342) and Active Blind Spot Assist
are activated in the on-board computer.
XTurn the SmartKey to position 2 in the
ignition lock.
Warning lamps : light up red in the
exterior mirrors for approximately 1.5
seconds and then turn yellow.
Active Lane Keeping Assist
Important safety guidelines
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of a camera
at the top of the windshield. Active Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
:Active Lane Keeping Assist camera
If you select km on the on-board computer in
the Display unit Speed-/odometer:
(Y page 341) function, Active Lane Keeping
Assist is activated starting at a speed of
60 km/h. If the mph display unit is selected,
the assistance range begins at 40 mph.
GWarning
Active Lane Keeping Assist does not keep
your vehicle 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
function if:
Rseveral or no lane markings for a single lane
are present.
Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray.
Rthere is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
