for a lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
XRemove your foot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
iIf you do not fully release the accelerator
pedal, the DistancePilotSuspendedmes-
sage appears in the multifunction display. The set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate Distance Pilot DISTRONIC
when stationary. The lowest speed that can be
set is 20 mph (30 km/ h).
XBriefly pull the cruise control lever towards
you ;or press it up :or down =.
Distance Pilot DISTRONIC is activated.
Activating at the current speed/last
stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
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 Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.
Driving with Distance Pilot DISTRONIC
Pulling away and driving
XIf you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
XBriefly pull cruise control ?lever towards
you.
or
XAccelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
iThe vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi-
cle then brakes automatically. There is a risk
of an accident. Be ready to brake at all times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you have selected the Sor S+
drive program. Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. When you select the Cdrive pro-
gram, the vehicle accelerates more gently. This
setting is recommended in stop-and-start traf-
fic.

lecting the drive
program (Ypage 116).

Changing lanes
If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if:
Ryou are driving at a speed greater than
45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RDistance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
iWhen you change lanes, Distance Pilot
DISTRONIC monitors the left lane.
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 141).
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.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
The elec tric par
king brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
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
Ra system malfunction occurs
Rthe power supply is insufficient
If a malfunction occurs, the transmission may
also shift to position jautomatically.
Setting a speed
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 press
the 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.

Driving and parking

iIf you accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
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, dependent on vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 142).
iMake sure that you maintain the minimum
distance to the vehicle in front as required by
law. Adjust the distance to the vehicle in front
if necessary.
XTo increase: turn control;in direction =.
Distance Pilot DISTRONIC then maintains a
greater distance between your vehicle and
the vehicle in front.
XTo decrease: turn control;in direction :.
Distance Pilot DISTRONIC then maintains a
shorter distance between your vehicle and
the vehicle in front.
Deactivating Distance Pilot DISTRONIC
There are several ways to deactivate Distance
Pilot DISTRONIC:
XBriefly press the cruise control lever for-
wards :.
or
XBrake, unless the vehicle is stationary
When you deactivate Distance Pilot DISTRONIC,
the Distance Pilot Off
message appears in
the multifunction display for approximately five
seconds.
iThe last speed stored remains stored until
you switch off the engine.
iDistance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal.
Distance Pilot DISTRONIC is automatically deac-
tivated if:
Ryou engage the electric parking brake or if the
vehicle is automatically secured with the elec-
tric parking brake

Driving an d parking

Cornering, going into and coming out of a
bend
The ability of Distance Pilot DISTRONIC to
detect vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles traveling on a different line
Distance Pilot DISTRONIC may not detect vehi-
cles which are not driving in the middle of their
lane. The distance to the vehicle in front will be
too short.
Other vehicles changing lanes
Distance Pilot DISTRONIC has not detected the
vehicle cutting in yet. The distance to this vehi-
cle will be too short.
Narrow vehicles
Distance Pilot DISTRONIC has not yet detected
the vehicle in front on the edge of the road
because of its narrow width. The distance to the
vehicle in front will be too short.
Obstructions and stationary vehicles
Distance Pilot DISTRONIC does not brake for
obstacles or stationary vehicles. If, for example,
the detected vehicle turns a corner and an
obstacle or stationary vehicle is then revealed,
Distance Pilot DISTRONIC will not brake for
them.
Crossing vehicles
Driving systems143
Driving and parking
Z

Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. Acti-
vating Distance Pilot DISTRONIC at, for exam-
ple, a traffic light with crossing traffic, could
cause your vehicle to pull away at the wrong
time.

Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and a detec-
ted obstacle visually and audibly.
Parking Assist 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. Make sure that there
are no persons, animals or objects etc., in the
maneuvering area while maneuvering and park-
ing or exiting parking spaces.
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
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 of a truck or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you:
Rswitch on the ignition
Rshift the transmission to position h,kor
i
Parking Assist PARKTRONIC is deactivated at
speeds above approx. 11 mph (18 km/h). It is
reactivated at lower speeds.
Range of the sensors
General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
:Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them (
