Important safety notes G
WARNING
PARKTRONIC is only an aid and may not
detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift to position D,Ror Non vehicles with
automatic transmission
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. 200

Important safety notes G
WARNING
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
WARNING
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
203Driving and parking Z

G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! 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.
Parking Guidance is an electroni cparking 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 200).
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance 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, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs
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 201) warning messages during the
parking procedure.
R when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel fitted. R
make sure that the tyre pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis 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, 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 kerb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
Detecting parking spaces Example: vehicles with automatic transmission
:
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
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 30 km/h, you will see
parking symbol ;as a status indicator in the
instrument cluster.
When a parking space has been detected, an
arrow towards the right =or the left :also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as 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. 204
Driving systemsDriving and parking

Parking Guidance 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 approximately
15 m away from it.

Important safety notes G
WARNING
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.
General notes ATTENTIO
NASSIST 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.
ATTENTIO
NASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
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 sid ewind
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 with COMAND APS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display Example: vehicles with automatic transmission
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the
nhear an inter-
mittent warning tone twice and the Atten‐ tion Assist: Drowsiness detected mes-
sage appears in the multifunction display. 208

display.
X If necessary, take a break.
X Press the abutton to confirm the mes-
sage.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Speed Limit Assist
Important safety notes G
WARNING
Speed Limit Assist is only an aid and may
detec tspeed limit signs 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 snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees. R
the traffic signs are poorly illuminated.
R there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads.
Traffic signs always have priority over the
Speed Limit Assist display. Speed Limit Assist
cannot detect road and traffic conditions. It is
not a substitute for attentive driving.
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. :
Speed Limit Assist camera
Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does not detec tany traffic
signs, the speed limit from the digital road
map is take nand shown in the display.
Speed Limit Assist detects the traffic signs
