WARNING
Active Blind Spo tAssist monitor scertain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the syste mdoes
not brake the vehicle to cor rect your course.
If the lane sare very wide, it may not be pos-
sibl etom onitor the complet ewidth of the
neighbourin glane. For this reason, vehicles in
the nex tlane may not be detected, especially
if they are driving in astaggered formation.
Thi sm ay be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
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.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoyour vehicle may
be indicated, especially if the vehicles ar enot
drivin ginthe middle of their lane. This may
be the case if ther eare vehicles at th eedge
of their lane nearest your vehicle. Due to the nature of the system:
R
warnings may be issued in error when driv-
ing close to crash barriers or simila rsolid
lane borders.
R warnings ma ybeinterrupted whe ndriving
alongsid elong vehicles, such as lorries, for
ap rolonged time.
Tw oA ctive Blind Spo tAssist radar sensors
ar ei ntegrated into the front and rear bumpers
respectively. An additional radar sensor is
locate dbehind the cover in the radiator grille.
Make sure that the bumper sare free of dirt,
ice or slus haround th esensors. The rear sen-
sors must not be covered, e.g. by bicycle
racks or overhanging loads. Followin ga
severe impac torinthe even tofdamage to
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop. Blind Spot Assis tmay otherwise
not work properly.

NING
Activ eBlindS pot Assist is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Automatic braking by the
system may not always be sufficien ttoavoid
ac ollision .Insuch cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries .Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat-
eral distance betwee nyou and other road
users or obstacles. You can ,for example,
coun tersteer gently or depres sthe accelera-
tor pedal at any tim etocancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correc tsteering and for braking in good time.
Alway sadapt your drivin gstyle to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yoursel fand others.
Eithe ravery slight course-correcting brake
application, or non eatall, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R av ehicle approaches too closely on the
side.
R you have adopted asporty driving style with
high cor nering speeds.
R you brake or accelerate decisively.

Warning vibra tion in th esteering wheel
Aw arnin gmay be given if afront wheel
passes ove ralane mar king. You will then be
warned by means of an intermittent vibration
in the steering wheel for up to 1. 5seconds.
In order that you are warned only when nec-
essary and in good tim eifyou cross the lane
marking, the system recognises cer tain con-
ditions and warns you accordingly.
The warnin gvibration occur searlier if:
R you approach the outer lane markin gona

Lane-correcting brak eapplication
If you leave your lane unde rcertain cir cum-
stances, the vehicle will brake briefl yonone

vehicle bac kinto the original lane.
Thi sfunction is available in the range between
60 km/ hand 200 km/h.
Al ane-correctin gbrake applicatio ncan only
be made after driving over asolid, recognis-
able lane marking. Befor ethis, awarning must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
If al ane-correcting brake application occurs,
the following appears in the multifunction dis-
play: i
Afurther lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. G
WARNING
Active Lane Keeping Assis tdoes not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Corrective braking may
not always be sufficient to return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assis tcannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles .Inrare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assis tcannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.

Observ ethe information on ESP ®
trailer
stabilisation (Y page 65)and on pull ing
away with atrailer. (Y page 141).
Vehicles wit hthe ON&OFFROAD package:
selec tthe trailer program (Y page 219) with
the off-road program selector wheel in the
cen treconsole.
Th em aximum permissible spee dfor vehicle/
trailer combination sdepends on the type of
trailer .Befor ebeginning the journey, check
the trailer's documents to see what the max-
imu mpermitted speed is. Observ ethe legally
prescribed maximum speed in the relevant
country.
For certai nMercedes-Ben zvehicles, the max-
imu mp ermissible rear axle load is inc reased
when towing atrailer. Refer to th e"Techni cal
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/ hfor
reasons concer ning the operating permit.
Thi salso applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics will be differe ntin comparison
to when drivin gwithout atrailer and it will
consume more fuel.
On long and stee pdownhil lgradients ,you
must select shift range 1,2or 3in good time.
i This also applies if you have activated
cruise con trol, 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.
