vehicle ahead and your vehicle’s current
speed indicate that the DISTRONIC PLUS will
not be capable of slowing the vehicle
sufficiently to maintain the preset following
distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident.
GWarning!
The DISTRONIC PLUS brakes your vehicle
with a maximum deceleration of 13 ft/s2
(4 m/s2). This corresponds to approximately
40% of the maximum deceleration of your
vehicle.
You must also apply the brakes yourself to
avoid a collision. The DISTRONIC PLUS brakes
the vehicle in an effort to restore the preset
distance or to maintain the set speed.
GWarning!
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLUS has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.

Switching on while driving
You can switch on the DISTRONIC PLUS when
the vehicle speed is above 20 mph
(30 km/h).
Below 20 mph (30 km/h), you can only switch
on the DISTRONIC PLUS if the preceding
vehicle has been detected and is shown in the
multifunction display. If you no longer see the
preceding vehicle in the multifunction display
and if it is no longer detected because it has
changed lanes, for example, the DISTRONIC
PLUS switches off and a signal sounds.

drive at the speed you dictate by pressing the
accelerator pedal.
Switching on when approaching a
stationary vehicle
It is helpful to switch on the DISTRONIC PLUS
display in the multifunction display to see that
a preceding vehicle is detected
( Y page 152). You can only switch on the
DISTRONIC PLUS below a speed of 20 mph
(30 km/h) when a preceding vehicle is
detected.
If the preceding vehicle is stationary, you can
only switch on the DISTRONIC PLUS if your
vehicle is also at a standstill.XPull the DISTRONIC PLUS lever briefly in

or
XBriefly step on the accelerator pedal.
Your vehicle starts off and adapts its speed
to the preceding vehicle.
Driving
If there is no preceding vehicle, the
DISTRONIC PLUS functions like the cruise
control ( Y page 146).
When the DISTRONIC PLUS detects that the
preceding vehicle is driving more slowly, it
brakes the vehicle in order to keep the
distance specified by you.
When the DISTRONIC PLUS detects that the
preceding vehicle is driving faster, it
accelerates the vehicle up to the set speed.

GWarning!
The Parking Guidance is only an aid and may
display parking spaces that are not suitable
for parking such as
R no-parking zones
R parking space with unsuitable road/ground
surface
R driveways
R entrances/exits
The Parking Guidance scans for and measures
potential parking spaces when driving past.
Subsequent changes to the parking space are
not taken into account. This may be the case
if the position of the vehicle parked in front or
behind the space changes or obstacles in the
parking space are moved.
The Parking Guidance does not relieve you of
the responsibility to pay attention. If you only
rely on the Parking Guidance, you may cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering.
GWarning!
The system cannot detect objects located
above the area that the sensors scan. These
objects, e.g. protruding load, overhang, or
truck tail lifts, will be ignored when computing
the parking procedure. The Parking Guidance
might therefore provide untimely steering
instructions. This could cause a collision.
Thus, do not use the Parking Guidance in such
situations.
GWarning!
Make sure no persons or animals are in the
area in which you are maneuvering. You could
otherwise injure them.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
Use the Parking Guidance for parking spaces
that are
R parallel to the direction of travel
R located on straight streets, i.e. not in
curves
R on the same level as the street, i.e. not on
sidewalks, for example.
Parking instructions:
R On narrow streets, drive by the parking
space as close as possible.
R Parking spaces that are dirty, overgrown or
located in front of trailers may not be
detected correctly.
R Snowfall or heavy rain may cause imprecise
measurement of the parking space.
R Also observe the Parktronic system
warning indicator ( Y page 167) while the
Parking Guidance is active.
R You may not use the Parking Guidance
when transporting cargo that protrudes the
vehicle.
R Do not use the Parking Guidance when
driving with snow chains or when a spare
wheel is mounted.
R How well your vehicle will be parked after
completion of the Parking Guidance
depends on the position and shape of the
vehicles parked in front of and behind the
parking space as well as the conditions of
the immediate surroundings. In certain
cases, the Parking Guidance may guide you
too far into the parking space or not far
enough. If this is the case, cancel the
parking procedure with the Parking
Guidance and correct the vehicle position
yourself.
Detecting a parking space
The Parking Guidance is active when driving
forward. The system operates at a vehicle

non-scratching cloth ( Y page 263).
Blind Spot Assist
The Blind Spot Assist uses radar sensors to
monitor the area on both sides of your
vehicle. It will assist you when you change
lanes driving at speeds of above 20 mph
(30 km/h). A red warning lamp will come on
in the exterior rear view mirror as soon as
another vehicle is detected. If you then
activate the corresponding turn signals to
change lanes, the red warning lamp flashes
and warning sounds (collision warning). The
Blind Spot Assist operates using sensors in
the rear bumper.
GWarning!
The Blind Spot Assist is only a driving aid and
may not detect all vehicles.
The Blind Spot Assist may not be able to
detect narrow vehicles such as motorcycles
or bicycles, or it may not detect them until it
is too late.
The monitoring function may be impaired if
your sensors are dirty, subject to heavy spray,
or if visibility is poor due to e.g. snow, rain, or
fog. This can result in vehicles not being
detected or being detected too late.
The Blind Spot Assist cannot detect road,
traffic and weather conditions.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others.
In order for the Blind Spot Assist to function,
the radar sensors must be switched on and
operational.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 144). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are
deactivated:

When you shift the automatic transmission in
reverse gear R, yellow indicator lamps : in
the exterior rear view mirrors goes out after
approximately 3 seconds. The Blind Spot
Assist is then not active.
The brightness of indicator lamps/warning
lamps : is controlled automatically
depending on the brightness of the ambient
light.
GWarning!
The Blind Spot Assist is not active at speeds
below approximately 20 mph (30 km/h). The
yellow indicator lamps in the exterior rear
view mirrors are illuminated. You will not be
alerted to the presence of vehicles in the
monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others.
Collision warning
If a vehicle is detected in the Blind Spot Assist
range and you activate the turn signal, a two-
tone warning will sound once. Red warning
lamp : on the corresponding side of the
vehicle will flash.
GWarning!
Do not change lanes or make turns, while red
warning lamp : is flashing. Doing so could
result in an accident and serious injury to
yourself and others.
XRemain on the lane that you are currently
on until traffic conditions permit to change.
If the turn signal remains on, red warning
lamp : will flash to indicate that vehicles
have been detected. No further audible
warnings will sound.
Lane Keeping Assist
The Lane Keeping Assist supports you at a
vehicle speed of above 40 mph when you
have set the display unit to miles in the
Display Unit Speed-/Odometer: menu in
the control system (Y page 141). When you
have set the display unit to km, the system
supports you at a vehicle speed of above
60 km/h. When the Lane Keeping Assist
detects lane markings, the system is
designed to alert you in case you leave your
lane unintentionally. A warning is usually
issued when a front wheel is on the lane
marking. An interval vibration in the steering
wheel that lasts for up to 1.5 seconds will
then alert you.
The Lane Keeping Assist monitors the area in
front of your vehicle via camera :.
The system can distinguish various
conditions in order to alert you early enough
and to avoid unnecessary warnings when
crossing lane markings.
The warning is issued sooner when
Rcutting a curve on the outside of the turn
Rdriving on very wide lanes such as highway
lanes
Rthe system recognizes dividing lines
because crossing them is often crucial due
to soft shoulders or guardrails behind for
example
