procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations.
G
Risk of accident
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation .Insome cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 171) warning messages during the
parking procedure.
R you can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be cancelled. R
when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains or an emergency spare wheel are
fitted.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Active Parking
Assist may guide you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the kerb. If necessary, you should abort the
parking procedure with Active Parking
Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be aborted.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Detecting parking spaces Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 35 km/h, you will see
the parking symbol as a status indicator in the
instrumentc luster.Active Parking Assist only
displays parking spaces on the front-
passenger side as standard .Parking spaces
on the driver's side are displayed as soon as 174
Driving systemsDriving and parking

the tur
nsignal on the driver's side is activa-
ted. If you wish to park in a space on the driv-
er's side, the indicator on the driver's side
must remain on. This must remain switched
on until you acknowledge the use of Active
Parking Assist by pressing the abutton
on the multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. Detected parking space (example)
:

; Parking symbol
= Detected parking space on the right
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 m longer than your
vehicle
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.

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
177Driving and parking Z

ATTENTION ASSIST assesses your level of
fatigue or lapses in concentratio
nby taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R driving conditions, e.g. time, driving time
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND APS or
making a telephone call wit hit
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed

Important safety notes i
Speed Limit Assist is not operational in all
countries.
Speed Limit Assist, in conjunction with your
navigation system, shows you speed limits it
has detected in the multifunction display .The
display appears when traffic signs indicating
a speed limit or end of a speed limit zone are
detected. If Speed Limit Assist does not
detect any traffic signs, it adopts the speed
limit in the digital map and shows it in the
display.
Speed Limit Assist detects signs with a cam-
era at the top of the windscreen. 178

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 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.
You are responsible for safety and must drive
in accordance with traffic conditions. You
could otherwise endanger yourself and oth-
ers. The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R on bends, on uphill gradients or downhill
gradients.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multifunction display. This is
also the case if you cannot switch on the
main-beam headlamps because of oncoming
traffic. G
Risk of accident
Night View Assist Plus does not detect
objects in the immediate vicinity of the vehi-
cle. Look through the windscreen when
manoeuvring. Make sure that there are no
people or animals in the area in which you are
manoeuvring.
i Infrared light is not visible to the human
eye and therefore does not dazzle. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-

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
