As
aresult, BAS PLUS may not intervene in all
critical situations. There is arisk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensor soranythin gelse
covering the sensors
R snow or heavy rain
R interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R an arrow vehicle travelin ginfront, e.g. a
motorbike
R av ehicle travelin ginfrontonad ifferent line
relative to the center of your vehicle
Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensor schecked at aqualified
specialist workshop. This also applies to
collisions at low speeds where ther eisno
visible damage to the fron tofthe vehicle.
Braking assistance To prevent
acollision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision
When driving at aspeed under 20 mph
(30 km/h):ify ou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at aspeed greater than
20 mph (30 km/h):ify ou depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure to avalue adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger protection measures (PRE-SAFE
®
)a re
activated simultaneously.
X Keep the brake pedal depressed until the
emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual if:
R you release the brake pedal
R there is no longer arisk of collision
R no obstacle is detected in front of your
vehicle ESP

DISTRONIC PLUS. G
WARNING
DISTRONIC PLUS brakes your vehicle with up
to 40% of the maximum braking force. If this
braking force is insufficient ,DISTRONIC PLUS
warns you visually and audibly. There is arisk
of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in front,f
or vehicle speed, for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Brakin gor
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
coverin gthe sensors
R snow or heavy rain
R interference by other radar sources
R strongr adar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detect sa
vehicle in front,D ISTRONIC PLUS may
unexpectedly accelerate the vehicle to the
stored speed.
This speed may:
R be too high if you are driving in afilter lane
or an exit lane
R be so high in the right lane that you pass
vehicles driving on the left (left-han ddrive
countries)
R be so high in the left lane that you pass
vehicles driving on the right (right-hand
drive countries)
If there is achange of drivers, advise the new
driver of the speed stored.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
Vehicles are detected with the aid of the radar178

Load compensation
The vehicle can compensat
edifferences in
th ev ehicle level by raisin gorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
R ad oor or the trunk lid/tailgate is opened
R the parked vehicle is unlocked
For larger level changes, the engine must be
running. 4MATIC (permanent four-wheel drive)
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,f or vehicle speed, for braking in good
time and for staying in your lane.
If ad rive wheel spins due to insufficien tgrip:
R Only depress the accelerator peda lasfar
as necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicl ewith one axle
raised. This may damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remai neithe ront he ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
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.
4MATIC ensures that allf our wheels are
permanently driven. Together with ESP ®
,it
improves the traction of you rvehicle
whenever adrive wheel spins due to
insufficient grip. PARKTRONIC
Important safet ynotes PARKTRONIC is an electronic parkin
gaid with
ultrasonic sensors. It indicates visually and
audibly the distanc ebetween your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacemen tfor your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting aparkin gspace. When
maneuvering, parkin gorpulling out of a
parkin gspace, make sure that ther eare no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detec tsuch objects
when they are in th eimmediat evicinity of
th ev ehicle. You could damag ethe vehicle
or the objects.
The sensors may not detect snow and other
objectst hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or apneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
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. Driving systems

Blind Spot Assist General notes
Blind Spot Assist uses
aradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from aspeed of
approximately 20 mph (30k m/h). Awarning
displa yinthe exterio rmirrors draws your
attention to vehicles detected in the
monitored area. If you the nswitc hont he
correspondin gturns ignal to change lanes,
you will also receive avisual and audible
collision warning. Blin dSpot Assist uses
sensors in the rear bumper for monitoring
purposes. For Blin
dSpot Assist to assist you, the radar
sensor system must be operational.
Important safety notes G
WARNING
Blin dSpot Assist does not reac tto:
R vehicles overtaken too closely on the side,
placin gthemint he blind spot area
R vehicles which approach with alarge speed
differential and overtake your vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions
carefully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
