The remote control has amaximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objectsb etween the remote control
and the vehicle
R the remote control being in an unfavoura-

On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing atrailer,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
If as lower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain apreset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cle sd riving on adifferent line. Therefore,
always pa yattention to traffic conditions even
when DISTRONIC PLU Sisactivated. Other-
wise, yo umay fai ltorecognis edanger sin
time ,cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLU Scanno ttake account of road
and traffic conditions .IfDISTRONIC doe snot
recognise or no longer recognises the vehicle
in front,don ot activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to alane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on amotor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tancec ontrol may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. You will find further
information under "Radar sensor system"
in the index.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 345).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 229) and operational. 172

Tips for driving with DISTRONIC PLUS General notes
The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary .DISTRONIC PLUS is then

Important safety notes 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 receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 185). G
WARNING
Parking Guidance is merely an aid and may
recommendp arking 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
Objectsl ocated 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.

ynotes
Blind Spot Assist uses aradar senso rsystem
to monitor th eareas on bot hside sofy our
vehicle. Blind Spot Assis tprovide sassistance
at speeds higher than 30 km/h. Awarning
display in the exterior mirrors draw syour
attention to detected vehicles in the moni-
tored area .Ifyou then switch on the corre-
sponding turn signa ltochange lane, you will
alsor eceive avisual and acoustic collision
warning. The Blind Spot Assist monitoring
system usess ensors in the rear bumper. G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycle sorbicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
yours urroundings. Otherwise, you may fail to
recognise danger sintime, caus eanaccident
and injure yourself and others.
The radar sensor system is automatically
deactivate dnearradio telescope facilities

For Blin dSpotA ssist to assist you when driv-
ing, the radar sensor system must be activa-

Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly

Active Blind Spot Assist Important safety notes
Active Blind Spot Assist uses
aradar sensor
system to monitor the side areas of your vehi- cle that are behind the driver.
Awarning dis-
play in th eexteri or mirror sdraws your atten-
tio ntod etected vehicles in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also
receive avisual and acoustic collision warn-
ing. If arisk of lateral collision is detected,
corrective braking may help you avoid acol-
lision. To support the course-correcting brake
application, Active Blind Spot Assist also uses
the forward-facin gradar sensor system.
Active Blind Spot Assist provides assistance
at speeds higher than about 30 km/h. G
WARNING
Active Blind Spot Assist is only an aid and may
detect vehicles/obstacles 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 the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at asmall dis-
tancea nd then enter the blind spot area.
