Cruis econtro l
General notes
Cruise contro lmaintain s aconstant road speed
fo ryou. It brake sautomatically in order to avoid
exceedin gth eset speed. Change into alowe r
gear in goo dtime on lon gand steep downhill
gradients. Thi sis especially important if th e
vehicle is lade nor towin g atrailer .By doin gso,
you will mak euse of th ebraking effect of th e
engine. Thi srelieves th eload on th ebrake sys -
te m and prevents th ebrake sfrom overheatin g
and wearin gto oquickly.
Use cruise contro lonly if road and traffic con-
dition smak eit appropriat eto maintain asteady
speed fo r aprolonged period. You can stor eany
road speed abov e20 mph (30 km/h).
Important safet ynotes
Cruise contro lcan neither reduce th eris kof an
acciden tif you fai lto adapt your drivin gstyle no r
override th elaws of physics. Cruise contro lcan -
no ttake into accoun tth eroad, traffic and
weather conditions. Cruise contro lis only an
aid. You are responsible fo rmaintainin g asafe
distanc eto th evehicle in front, fo rvehicle
speed, fo rbraking in goo dtime and fo rstayin gin
lane. Do no
tuse cruise control:
Rin road and traffic condition swhic hdo no t
allow you to maintain aconstant speed, e.g. in
heav ytraffic or on windin groads
Ron slipper yroad surfaces. Brakin gor accel-
erating could cause th edrive wheels to los e
traction and th evehicle could then skid
Rwhen there is poo rvisibility, e.g. due to fog,
heav yrain or snow
If there is achang eof drivers, advise th ene w
driver of th espeed stored.
iThe speed indicated in th espeedometer
may diffe rslightly from th espeed stored.

XAccelerate the vehicle to the desired speed.
XBriefly press the cruise control lever up:or
down ;.
XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically applying the brakes.
Storing the current speed or calling up
the last stored speed
GWARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ?.
XRemove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly pressthe cruise control lever up
:or down ;to
the pressure point.
Every time the cruise control lever is pressed
up : or down ;the last speed stored is
increased or reduced.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly press
the cruise control lever up :or down ;
beyond the pressure point.
Every time the cruise control lever is pressed
up : or down ;the last speed stored is
increased or reduced.
iCruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever forward
=.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou engage the electric parking brake
Ryou are driving at less than 20 mph (30 km/h)
RESP®intervenes or you deactivate ESP®
Ryou shift the transmission to position i
while driving
If cruise control is deactivated, a warning tone
sounds. You will see the Cruise Control Off
message in the multifunction display for approx-
imately five seconds. The message on the mul-
tifunction display disappears and the segments
on the speedometer go out.
iWhen you switch off the engine, the last
speed stored is cleared.
Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically so that the set speed is not exceeded.
170Driving systems
Driving an d parking

Change into a lower gearingood time on long
and steep downhillgradients. This isespecially
impo rtant ifthe veh icle isladen. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quickly.
If Distance Pilot DI STRONIC detects that there is
a risk of a co llision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a co lli-
sion. An intermittent warning tone willthen
sound and the distance warning lamp willlight
up inthe instrument cluster. Brake immediately
in order to increase the distance to the veh icle in
front or take evasive action pro videdit is safe to
do so.
Distance Pilot DI STRONIC operates inthe range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DI STRONIC while driv -
ing on roads with steep gradients.
Sin ce Distance Pilot DI STRONIC transmits radar
waves, itcan resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter inthe Operator's Manual if
questions are asked about this.

Important safety notes
GWARNING
Distance Pilot DI STRONIC does not react to:
Rpeople or animals
Rstationary objects on the road, e.g. stoppe d
or parked vehicles
Roncoming vehicles and crossing traffic
As a result, Distance Pilot DI STRONIC may
neither givewarnings nor intervene insuch
situations. There isa risk of an accident.
Alwa ys pay careful attention to the traff icsit-
uation and be ready to brake.
GWARNING
Distance Pilot DI STRONIC cannot always
clearly identify other road users and co mplex
traff icsituations.
In such cases, Distance Pilot DI STRONIC may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither givea warning nor intervene
Raccelerate or brake unexpect edly
There isa risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
GWARNING
Distance Pilot DI STRONIC brakes your vehicle
with up to 50% of the maximum possible
deceleration. If this deceleration isnot suffi-
cient, Distance Pilot DI STRONIC alerts you
wit h a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself inthese situations
and try to take evasive action.
!When Distance Pilot DI STRONIC or the
HOLD function are activated, the vehicle
brakes automatically in certain situations.

To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
Rwhen towing the vehicle
Rin the car wash
Distance Pilot DISTRONIC can neither reduce
the risk of an accident if you fail to adapt your
driving style nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use Distance Pilot DISTRONIC:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may:
Rbe too high if you are driving in a turning lane
or an exit lane
Rbe so high in the right lane that you pass vehi- cles driving on the left (in countries where
they drive on the right)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.

Stopping
GWARNING
If you leave the vehicle when it is only being
braked by Distance Pilot DISTRONIC, it could
roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDistance Pilot DISTRONIC is switched off
using the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always deactivate
Distance Pilot DISTRONIC and secure the
vehicle against rolling away.
Further information on deactivating Distance
Pilot DISTRONIC (
Ypage 176).
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. When Distance Pilot DISTRONIC is activated,
the transmission shifts automatically to position
j
if:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission may
also be shifted to position jautomatically.

last speed stored after you have finished over-
taking.
Setting a specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, depending on vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 175).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.

vention sin aspeed range from 0 –125mph
(0 -20 0km/h).
It monitors th eare ain fron tof your vehicle by
means of multifunction camera :,fixed at th e
to pof th ewindshield .
In aspeed range from 0 -37 mph (0-60 km/ h),
Steering Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Pilot focuses on clear lane markings
(left and right), focusing on the vehicle in front
only if clear lane markings are not present.
If these conditions are not present, Steering
Pilot cannot provide assistance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes
Distance Pilot DISTRONIC and Steering Pilot can neither reduce the risk of an accident if you fail
to adapt your driving style nor override the laws
of physics. Distance Pilot DISTRONIC with
Steering Pilot cannot take into account road,
weather or traffic conditions. Distance Pilot
DISTRONIC with Steering Pilot is only an aid.
You are responsible for maintaining a safe dis-
tance to the ve
hicle in front, for vehicle speed,
for braking in good time and for staying in lane.
Distance Pilot DISTRONIC with Steering Pilot
does not detect road and traffic conditions and
does not detect all road users. If you are follow-
ing a vehicle which is driving towards the edge of
the road, your vehicle could come into contact with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
Obstacles such as traffic markers on a con-
struction site that are on the lane or projecting
out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in theopposite direction.
DISTRONIC PLUS with Steering Pilot cannot
continuously keep your vehicle in lane. In some
cases, 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
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road su rface i
s wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no or several unclear lane markings
for one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions on
the roadway
The system is switched to passive and no longer
assists you by performing steering interventions
if:
Ryou actively change lane
Ryou switch on the turn signal
Ryou take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering
Pilot is automatically active once more.

Steering Pilot cannot provide assistance:
Ron very sharp corners
Rwhen towing a trailer
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes on Distance Pilot DISTRONIC (
Ypage 171).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel, a warning tone also
sounds to remind you to take control of the
vehicle after five seconds at the latest. Steering
Pilot is then switched to passive. Distance Pilot
DISTRONIC remains active.
