nalsource of radio or
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
take ninto account whe nthe parkin gproce-
dure is calculated, e.g .overhanging loads ,tail
sections or loading ramps of good svehicles.

Risk of accident
The reversing camera is only an aid and may
display obstacles in adistorted or incorrect

You are always responsible for safety and
must continue to pay attention to your imme-

manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endanger yourself and oth-
ers. G
Risk of accident
Under the following circumstances, the

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

Gen
eral information i
When towing atrail er,s et the tyr epres-
sure on th erear axle of the towing vehicle
for am aximum load; se ethe tyr epressure
table in th efuel filler flap.
You will find installatio ndimensions and loads
in the "Technical data” section
(Y page 322).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However ,the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight .Do
not use anoseweight of less than 50 kg,
otherwise the trailer ma ycome loose.
Bear in min dthat the payload and the rear
axl eload ar ereduced by the actual nose-
weight.
Please not ethat when towing atrailer, PARK-
TRONIC (Y page 174) and parkin gguidance
(Y page 177 )are onl yavail ablew ith limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer wit haheight-adjustable draw-
bar.
Driving tips i
Observ ethe notes on ESP ®
trailer stabi-
lisation (Y page 58).
In Germany, the maximum permissible speed
for vehicle/ trailer combinations depends on
the type of trailer and is either 80 km/ hor
100 km/h. In some countries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Befor ebeginnin gthe
journey ,check the trailer's documen tsto see
what the maximum permitted speed is.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical data
"section to fin dout whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing atrailer,
th ev ehicle/ trailer combination may not
exceed amaximum spee dof100 km/h for
reasons concerning the operating permit.
This als oapplies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 10 0km/h.
When towing atrailer, your vehicle's handling
characteristics wil lbedifferent in comparison
to when drivin gwithout atrailer.
Th ev ehicle/ trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demand smore sensitive steering
R consume smore fuel
On long and steep downhil lgradients ,you
must shift to alower gear in good time, or on
vehicles with automatic transmission ,select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly .Ifyou need
additional braking, depress the brake pedal
repeatedly rather than con tinuously.
Driving tips R
Maintain agreater distance from th evehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea 188
