Risk of accident
DISTRONI CPLUS cannot take account of road

Important safety notes G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles .This system does not
reliev eyou of the need to pay attention.
You are always responsible for safet yand
must continue to pay attention to your imme-
diate surroundings whe nparking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise ,they
coul dbei njured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visual lyand
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
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. 174

ultrasoun dwaves.
X See if PARKTRONIC functions in adifferent location. Parking Guidance
Important safet ynotes 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 receiv esteering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 174). G
Risk of accident
Parking Guidance is merely an aid and may
recommen dparking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited ,drive-
ways, unsuitabl esurfaces, 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. Thes eare not

dure is calculated, e.g .overhanging loads ,tail
sections or loading ramps of good svehicles.

Important safety guidelines Blin
dSpot Assist uses aradar sensor system
to monitor the areas on both sides of your
vehicle. Blin dSpot Assist provides assistance
at speeds higher than 30 km/h. Awarning
display in the exterior mirrors draws your
attention to vehicles in the monitored area. If
you then indicat eaturn toward sthat side
before changing lane, you will also receive
visual and audible collision warnings. For this
purpose, Blind Spot Assist uses sensor sinthe
rea rbumper. G
Risk of accident
Blind Spot Assis tiso nly an aid designe dto
assis tdriving. It may fail to detec tsome vehi-
cles and is no substitute for attentiv edriving.
Blind Spo tAssist can notd etect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motor cycles or bicycles ,or
only detec tthem too late.
Monitoring ma ybeaffected by dirty sensors,
stro ngspra yorp oor visibility caused by snow,
rai norm ist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injur eyoursel fand others.
The radar senso rsystem is automatically
deactivated near radio telescope facilities
(Y page 324).
For Blind Spot Assist to assist you when driv-
ing, the radar sensor syste mmust be activa-
ted (Y page 208 )and operational. Monitoring range of the sensors Blind Spot Assist monitors the area up to
three metres behind your vehicl
eand directly
next to your vehicl easshown in the diagram. Sid
eview, Coupé (example) G
Risk of accident
Blind Spot Assist monitors certain areas in the
immediate vicinit yofyour vehicle. Vehicles
that approach and driv epast at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation in
different lanes .This ma ybethe case if vehi-
cles ar edrivin gatt he edge of their lan ethat
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you ma yfail to
recognise dangers in time, cause an accident
and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in astag-
gered formation in different lanes .Inparticu- 184
