road, weather and traffic conditions.
DISTRONIC PLUS 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
DISTRONIC PLUS 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.
If DISTRONIC PLUS detects a risk of collision
but cannot sufficiently decelerate the vehicle
in order to maintain the set distance, you will
be warned visually and acoustically.
DISTRONIC PLUS cannot prevent a collision
without your intervention. An intermittent
warning tone will then sound and the distance
warning lamp will light up in the instrument
cluster. Brake immediately in order to
increase the distance from the vehicle in
front, or take evasive action, provided it is
safe to do so.
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line. Therefore,
always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognize dangers
in time, cause an accident and injure yourself
and others.
In particular, the detection of obstacles can
be impaired if there is:
R the sensor is dirty or covered
R snow or heavy rain
R interference by other radar sources
R there is the possibility of strong radar
reflections, for example, in parking
garages.
If DISTRONIC PLUS is activated, the vehicle
brakes automatically in certain situations.
This can happen unexpectedly, especially
when towing or in a car wash. There is a risk
of an accident. In these or similar situations,
deactivate DISTRONIC PLUS.
If you want DISTRONIC PLUS to assist you,
the following activation conditions must be fulfilled (
Y page 179) and the radar sensor
system must be operational.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must select shift range
1, 2 or 3
in good time. By doing so, you will make use
of the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle

in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Activating DISTRONIC PLUS Activation conditions
In order to activate DISTRONIC PLUS, the
following conditions must be fulfilled:
R
the

engine must be started. It may take up
to two minutes after pulling away before
DISTRONIC PLUS is operational.
R the parking brake must be released.
R the differential lock must be deactivated.
R ESP ®
must be active, but not intervening.
R the transmission must be in position D.
R the driver's door must be closed when you
shift from P to D or your seat belt must be
fastened.
R the front-passenger door and rear doors
must be closed.
R the vehicle must not skid.
R the DISTRONIC PLUS function must be
selected ( Y page 179).
R the transfer case must be in the HIGH
RANGE transmission position.
R the vehicle must not be on an uphill or
downhill gradient of more than 22-25%.
R the radar sensor must be free from dirt
(Y page 297). Driving systems

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.

General notes Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are in back of the driver. 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 lanes,
you will also receive an optical and audible
collision warning. If a risk of lateral collision
is detected, corrective braking may help you
avoid a collision. To support the course-
correcting brake application, Active Blind
Spot
Assist also uses the forward-facing radar
sensor system.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph(30 km/h).
Monitoring area G
WARNING
Active Blind Spot Assist monitors certain
areas
in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor
audible warnings are emitted and the system
does not brake the vehicle to correct your
course.
If the lanes are very wide, it may not be
possible to monitor the complete width of the
neighboring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
that edge of their lane which is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others. Driving systems

Driving and parking Z

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. Check in front,
behind and to the sides of the vehicle before
maneuvering, parking or exiting a parking
space. There must not be any persons,
animals or objects in the area in which you
are maneuvering.
PARKTRONIC cannot identify any persons or
objects outside of 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, R or 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.
