Index
The brakes function as usual again if:
R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to the maximum vehicle speed, adaptive
Brake Assist can react to moving obstacles
that have already been recognized as such at
least once over the period of observation.
Adaptive Brake Assist does not react to sta-
tionary obstacles.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R it is snowing or raining heavily
R there is interference from other radar sour-
ces
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle is traveling in front, e.g. a
motorbike
R a vehicle is traveling in front on a different
line
If adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the full brake boosting effect with the help of
BAS remains available.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. ASR (acceleration skid control)
General notes Important safety notes
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road
and weather conditions.
Vehicles without steering wheel buttons: if
ASR is malfunctioning, the
003Dindicator
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 221).
ASR significantly improves traction, i.e. the
transmission of power from the tires to the
road surface, and thus increases the vehicle's
driving stability. If the driving wheels start to
spin, ASR brakes individual drive wheels and
limits the engine torque. ASR thus signifi-
cantly assists you when pulling away and
accelerating, especially on wet or slippery
roads.
If traction on the road surface is not sufficient,
even ASR will not allow you to pull away with-
out difficulty. The type of tires and total
weight of the vehicle as well as the gradient
of the road also play a crucial role.
If ASR intervenes, the 0072warning lamp in
the instrument cluster flashes.
Activating/deactivating ASR G
WARNING
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel-
eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
! If you deactivate ASR, ESP ®
will still inter-
vene to stabilize the vehicle. Frequent brak-
ing automatically triggered by ESP ®
can
damage the brake system.
For this reason, deactivate ASR only briefly
and when absolutely necessary. 60

Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding 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 and behind
the protective strips of the B-pillars.
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles 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 to
detect some vehicles and is no substitute for
attentive driving.
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 warran-
ties, 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.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or anything else cover-
ing the sensors
R poor visibility, e.g. due to fog, heavy rain or
snow
R narrow and short vehicles, e.g. motorcy-
cles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their
lane
R barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. 164
Driving systemsDriving and parking
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 11.5 ft (3.5 m) to each side of
it. For this purpose, Blind Spot Assist uses
radar sensors in the rear bumper and behind
the protective strips of the B-pillars.
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 a clear warning situation may not occur.
The yellow indicator lamp on the relevant
side of the vehicle will then light up.
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, for
example trucks, for a prolonged time.
The four sensors of Blind Spot Assist are inte-
grated into the rear bumper and behind the
protective strips of the B-pillars. Make sure
that the bumper and protective stripping are
free of dirt, ice or slush in the vicinity of the
sensors. The radar sensors must not be cov-
ered, for example by cycle racks or overhang-
ing loads. Have the function of the radar sensors
checked at a qualified specialist workshop:
R
after a severe impact
R in the event of damage to the bumper
R in the event of damage to the protective
strips of the B-pillars
Blind Spot Assist may otherwise not work
properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated. 0043
Yellow indicator lamp/red warning lamp
If yellow indicator lamp 0043lights up:
R you are driving at less than 20 mph
(30 km/h)
R Blind Spot Assist is deactivated
R Blind Spot Assist is malfunctioning
R there is no clear warning, depending on the
situation
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in
the blind spot monitoring range, red warning
lamp 0043on the corresponding side lights up.
This warning occurs when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 14 mph (22 km/h).
Yellow indicator lamp 0043goes out if reverse
gear is engaged. Blind Spot Assist is then
deactivated. Driving systems

ings are suppressed for a certain period of
time.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
Lane Keeping Assist warns you earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a high-
way.
R the system recognizes solid lane markings.
Warnings are given later if:
R the road has narrow lanes.
R you cut the corner on a bend. PARKTRONIC
Important safety notes PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate sur-
roundings. You are responsible for safe
maneuvering, parking and pulling away. When
maneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuvering area.
PARKTRONIC does not account for obstacles
that are:
R beneath its detection range, e.g. persons,
animals or objects
R above its detection range, e.g. overhanging
loads, overhangs or truck loading ramps
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates the distance
between your vehicle and an object visually
and audibly.
Your vehicle features two separate sound
emitters with different frequencies for the warning tones. The warning ranges in front of
and behind the vehicle are indicated by dif-
ferent warning tones.
PARKTRONIC is activated automatically when
you:
R turn the key to position 2in the ignition lock
R release the parking brake and
R move the selector lever to D,Nor R.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reacti-
vated at speeds below 10 mph (16 km/h).
PARKTRONIC monitors the area around your
vehicle with sensors in the front and rear
bumpers.
Range of the sensors !
Pay particular attention to obstacles
above or below the sensors when parking,
such as flower pots or trailer towbars.
PARKTRONIC does not recognize such
objects when they are in the immediate
vicinity of the vehicle. You could damage
the vehicle or objects.
PARKTRONIC can suffer interference from:
R ultrasonic sources such as a truck's
compressed-air brakes, an automatic car
wash or a pneumatic drill
R attachments to the vehicle, e.g. rear
mounted racks
R number plates (vehicle license plates)
that are not affixed flat against the
bumper
R dirty or icy sensors 168
Driving systemsDriving and parking
The sensors must be free of dirt, ice or slush.
Otherwise, they cannot function correctly.
