Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors.
R visibility is poor, e.g. due to fog, heavy rain
or snow.
R there is a narrow vehicle traveling in front,
e.g. a motorcycle or bicycle.
R the road has very wide lanes.
R the road has narrow lanes.
R you are not driving in the middle of the lane.
R there are barriers or other road boundaries.
i USA only:
This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
General notes Blind Spot Assist uses a radar sensor system
to monitor both the left and right sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
collision warning. For this purpose, Blind Spot
Assist uses sensors in the rear bumper. Monitoring range of the sensors
Blind Spot Assist monitors the area up to
10 ft (3 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R
warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free from dirt,
ice or slush around the sensors. The rear
sensors must not be covered, for example by
bicycle racks or overhanging loads. Following
a severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly. 186
Driving systemsDriving and parking

R
you depress the brake pedal again with a
certain amount of pressure until 00D9
disappears from the multifunction display.
R you activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if
there is a malfunction, the transmission may
also be automatically shifted into position P.4MATIC (permanent four-wheel drive)
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the SmartKey to
position 0or 1in the ignition. Failure to do
this can cause damage to the drive train or
the brake system.
! A function or performance test should
only be carried out on a two-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficient grip.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
4MATIC when the current road, weather and
traffic conditions permit it to be done safely,
and adapt your driving style accordingly.
Drive carefully and maintain a suitable
distance to the vehicle in front.
i
In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
For information about driving off-road, see
(Y page 164). PARKTRONIC
Important safety notes !
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Ensure that the
areas in front, behind and to the side of the Driving systems
189Driving and parking Z

vehicle are safe before maneuvering, parking
or pulling away. There must not be any
persons, animals or objects in the area in
which you are maneuvering.
PARKTRONIC does not take into account any
persons or objects located below or above
the detection range. As a result,
PARKTRONIC cannot warn you about objects
in this area.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (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.
Range of the sensors General notes
0043
Example: sensors in the front bumper,
left-hand side Side view Top view
The sensors must be free from dirt, ice or
slush. Otherwise, they may not function
correctly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y
page 291).

warning display for the front area is located
on the dashboard above the center air vents.
The warning display for the rear area is
located on the headliner in the rear
compartment.
The warning display for each side of the
vehicle is divided into five yellow and two red
segments. PARKTRONIC is operational if
yellow segments showing operational

Important safety notes The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make
sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R the rear door is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker) R
if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this event, have the camera position and
setting checked at a qualified specialist
workshop Mercedes-Benz recommends
that you use an authorized Mercedes-Benz
Center for this purpose 192
