ESP ®
trailer stabilisation General information
ESP ®
trailer stabilisation is not available in
Mercedes-AMG vehicles.
If your vehicle/trailer combination begins to
lurch, ESP ®
assists you in this situation. ESP ®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com- bination has stabilised.
Important safety notes G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions. If your vehicle/trailer combination begins to
lurch, you can stabilise the vehicle/trailer com-
bination only by depressing the brake firmly.
ESP ®
trailer stabilisation is active above speeds
of approximately 65 km/h.
ESP ®
trailer stabilisation does not work if ESP ®
is deactivated or disabled because of a malfunc- tion.
Crosswind Assist General notes
Strong crosswind gusts can impair the ability of your vehicle to drive straight ahead. The cross-
wind driving assistance function integrated in
ESP ®
noticeably reduces these impairments.
Depending on the direction and intensity of the
side wind, ESP ®
is activated automatically.
ESP ®
engages with a stabilising application of
the brakes to assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 80 km/h when the vehicle is driving
straight ahead or cornering gently.
Important safety notes
Crosswind Assist does not work if ESP ®
is deac-
tivated or disabled because of a malfunction. EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 67). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have Driving safety systems
75Safety
Z

You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. Do not use
cruise control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to bring the vehicle under control by using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Mercedes-Benz Intelligent Drive
Mercedes-Benz Intelligent Drive stands for inno-
vative driver assistance and safety systems
which enhance comfort and support the driver in critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set a mile-
stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one well
thought-out system – for the safety of the vehi-
cle occupants and that of other road users.
Further information on driving safety systems
(Y page 66). Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Shift to a lower gear in
good time on long and steep downhill gradients.
Take particular note of this when driving a laden vehicle and when towing a trailer. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steadyspeed for a prolonged period. You can store anyroad speed above 30 km/h. If you have set a
permanent limit speed, you cannot set the
speed any higher than the fixed limit speed
(Y page 171).
Important safety notes Cruise control can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. Cruise control can- not take into account road, weather or traffic
conditions. Cruise control is only an aid. You are
responsible for maintaining a safe distance from the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use cruise control:
R in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on smooth or slippery roads. Braking or accel-
erating can 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.
If there is a change of drivers, advise the new
driver of the speed stored.
i The speed indicated in the speedometer
may differ slightly from the speed stored. Driving systems

Driving with DISTRONIC PLUS
Pulling away and driving
X To pull away with DISTRONIC PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X Accelerate briefly.
The vehicle pulls away and adapts its speed to
that of the vehicle in front. If no vehicle is
detected in front, the vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If DISTRONIC PLUS does not detect a vehicle in
front, the system operates like cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes the vehicle. In
this way, the specified minimum distance you
have selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it accelerates the vehicle to the
set speed.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style when you have selected the Sor S+ drive pro-
gram (Y page 148). Acceleration behind the
vehicle in front or to the set speed is then notice- ably more dynamic. If you have selected the Cor
E drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you in the following situations:
R You are driving at a speed greater than
70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang- ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small. Vehicles with COMAND Online multimedia
system: when you change lanes, DISTRONIC
PLUS monitors the right lane in the case of left-
side traffic or the left lane in the case of right-
side traffic.
Vehicles with Audio 20 multimedia system:
when you change lanes, DISTRONIC PLUS mon- itors the left lane on left-hand-drive vehicles or
the right lane on right-hand-drive vehicles.
Road and traffic conditions The following function is available only in vehi-
cles with the Driving Assistance Plus package.
The function is not operational in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations.
This is the case if, while you are following a vehi-
cle, DISTRONIC PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
R approach a tollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler-
ate. This is based on the current map data in the navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
of more than 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles in
the adjacent lane to the left.
Prevention of overtaking on the right applies to
countries where traffic drives on the right. In
countries where traffic drives on the left, over-
taking on the left is prevented accordingly. 174

The last speed stored remains stored until you
switch off the engine.
DISTRONIC PLUS is not deactivated if you
depress the accelerator pedal.
DISTRONIC PLUS is automatically deactivated
in the following situations:
R You apply the electric parking brake or if the
vehicle is automatically secured with the elec-
tric parking brake

DISTRONIC PLUS off message then appears on the multifunction display for approximately
five seconds.
Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of DISTRONIC PLUS to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late.
R Driving on a different line: DISTRONIC PLUS
may not detect vehicles that are not driving in
the middle of their lane. The distance to the
vehicle in front will be too short.
R Other vehicles changing lane: DISTRONIC
PLUS has not detected the vehicle cutting in
yet. The distance to this vehicle will be too
short.
R Narrow vehicles: DISTRONIC PLUS has not
yet detected the vehicle in front on the edge
of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles and stationary vehicles:
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals an
obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
R Crossing vehicles: DISTRONIC PLUS may mis-
takenly detect vehicles that are crossing your
lane. Activating DISTRONIC PLUS at traffic
lights with crossing traffic, for example, could
cause your vehicle to pull away unintention-
ally.
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated. Driving syste

DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle in
the centre of the driving lane by means of mod-
erate steering interventions in a speed range
from 0–200 km/h.
It monitors the area in front of your vehicle by
means of multifunction camera :, at the top of
the windscreen.
In a speed range from 0–60 km/h, Stop&Go
Pilot focuses on the vehicle in front, taking into
account lane markings, e.g. when you are fol-
lowing vehicles in a traffic jam.
At speeds of more than 60 km/h, Steering
Assist focuses on detected lane markings (left
and right), only focusing on the vehicle in front if detected lane markings are not present.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notesDISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. It cannot take into account road, weather or traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay- ing in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you are following a vehicle that is driving towards the edge of the carriageway, your vehi-
cle could come into contact with the kerb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
you have intentionally driven over a lane mark-
ing, can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not
leave the lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the roadway
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering
Assist and Stop&Go Pilot are automatically
active again. 178

M
MSolutions Only the red segments in
the PARKTRONIC warn-
ing displays are lit. You
also hear a warning tone
for approximately two
seconds.
PARKTRONIC is then
deactivated and the indi-
cator lamp on the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has been deactivated.
X If problems persist, have PARKTRONIC checked at a qualified spe-
cialist workshop. Only the red segments in
the PARKTRONIC warn-
ing displays are lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X
Clean the PARKTRONIC sensors (Y page 319).
X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X See whether PARKTRONIC functions in a different location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting a parking
space. You may also use PARKTRONIC
(Y page 185).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R In a zone where parking or stopping is pro-
hibited
R In front of driveways or entrances and exits
R On unsuitable surfaces 188

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all in the following situations:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in case of strong side winds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with DISTRONIC PLUS Steer-
ing Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when you continue the
journey in the following situations:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break Driving systems
