Blind Spot Assist supports you from a speed ofapproximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail todetect some vehicles and is no substitute forattentive driving. Always ensure that there issufficient distance to the side for other roadusers and obstacles.

There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
Lane Keeping Assist can neither reduce the riskof an accident if you fail to adapt your drivingstyle nor override the laws of physics. LaneKeeping Assist cannot take into account theroad, traffic and weather conditions. Lane Keep-ing Assist is merely an aid. You are responsiblefor the distance to the vehicle in front, for vehi-cle speed, for braking in good time and for stay-ing in your lane.
The Lane Keeping Assist does not keep the vehi-cle in the lane.

Active Blind Spot Assist
General notes
Active Blind Spot Assist monitors the areas oneither side of the vehicle that are not visible tothe driver with two lateral, rear-facing radar sen-sors. A warning lamp lights up in the exteriormirrors and draws your attention to vehicles
detected in the monitored area. If you thenswitch on the corresponding turn signal tochange lanes, you will also receive a visual warn-ing and hear a warning tone. If a risk of lateralcollision is detected, corrective braking mayhelp you avoid a collision. Before a course-cor-recting brake application, Active Blind SpotAssist evaluates the space in the direction oftravel and at the sides of the vehicle. For this,Active Blind Spot Assist uses the forward-facingradar sensors.
Active Blind Spot Assist supports you from aspeed of approximately 20 mph(30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is nota substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

Towing a trailer
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the
ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Ypage 364).
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
!If you have a trailer tow hitch retrofitted,changes to the engine cooling system may benecessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.
The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.
202Towing a trailer
Driving an d parking

For more information, please contact a qualifiedspecialist workshop.
Please observe the manufacturer's operatinginstructions for the trailer coupling if a detach-able trailer coupling is used.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehiclecorrectly, the trailer could become detached.
Make sure that the following values are notexceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towingvehicle
Rthe maximum permissible gross vehicleweight of both the towing vehicle and thetrailer
The applicable permissible values, which mustnot be exceeded, can be found:
Rin the vehicle documents
Ron the type plate for the trailer
Ron the vehicle identification plate
If the values differ, the lowest value applies.
When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning circle
This could impair the handling characteristics.
When towing a trailer, always adjust your speedto the current road and weather conditions. Donot exceed the maximum permissible speed foryour vehicle/trailer combination.
Notes on towing a trailer
General notes
RDo not exceed the maximum permissiblespeed for vehicle/trailer combinations in therelevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling onyour vehicle.
Further information on availability and oninstallation is available from any authorizedMercedes-Benz Center.
RThe bumpers of your vehicle are not suitablefor installing detachable trailer couplings.
RDo not install hired trailer couplings or otherdetachable trailer couplings on the bumpersof your vehicle.
RIf you no longer need the ball coupling,remove it from the ball coupling recess. Thiswill reduce the risk of damage to the ball cou-pling.
When towing a trailer, set the tire pressure onthe rear axle of the towing vehicle for a maxi-mum load; see the tire pressure table in the fuelfiller flap (Ypage 348).
Please note that when towing a trailer, the fol-lowing driving systems have limited availabilityor are not available at all:
RPARKTRONIC (Ypage 179)
RBlind Spot Assist (Ypage 193)
RActive Lane Keeping Assist (Ypage 200)
On vehicles without level control, the height ofthe ball coupling will alter according to the loadplaced on the vehicle. If necessary, use a trailerwith a height-adjustable drawbar.
You will find permissible trailer loads under"Technical data" (Ypage 364).
Driving tips
Observe the information on ESP®trailer stabili-zation (Ypage 71) and on pulling away with atrailer (Ypage 135).
The maximum permissible speed for vehicle/trailer combinations depends on the type oftrailer. Before beginning the journey, check thetrailer's documents to see what the maximumpermitted speed is. Observe the maximum per-missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-mum permissible rear axle load is increasedwhen towing a trailer. See the "Technical data"section to find out whether this applies to yourvehicle (Ypage 365). In the event of increasedrear axle load, the vehicle/trailer combinationmay not exceed a maximum speed of 60 mph(100 km/h) for reasons concerning the operat-ing permit. This also applies in countries in
