Activating at the current speed or last
stored speed G
WARNING
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. X
Briefly pull the cruise control lever towards
you 0043.
X Remove your foot from the accelerator pedal.
The first time Active Distance Assist
DISTRONIC is activated, it stores the current
speed or regulates the speed of the vehicle to
the previously stored speed. Driving systems

Driving with Active Distance Assist
DISTRONIC Pulling away and driving
X
If you want to pull away with Active Dis-
tance Assist DISTRONIC: remove your foot
from the brake pedal.
X Briefly pull cruise control lever 0043towards
you.
or
X Accelerate 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.
i The 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, Active Distance
Assist DISTRONIC operates in the same way as
cruise control.
If Active Distance Assist DISTRONIC detects a
slower-moving vehicle in front, it brakes your
vehicle. In this way, the distance you have selec- ted is maintained.
If Active Distance Assist 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 Active Distance Assist DISTRONIC supports a
sporty driving style when you have selected the
S or S+ drive program. Acceleration behind the
vehicle in front or to the set speed is then notice- ably more dynamic. When you select the Cdrive
program, the vehicle accelerates more gently. This setting is recommended in stop-and-start
traffic.
Additional information on selecting the drive
program (Y
page 116).
Changing lanes If you change to the overtaking lane, Active Dis-
tance Assist DISTRONIC helps you if:
R you are driving at a speed greater than
45 mph (70 km/h)
R you switch on the appropriate turn signal
R Active Distance Assist 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.
i When you change lanes, Active Distance
Assist DISTRONIC monitors the left lane.
Stopping G
WARNING
If you leave the driver's seat when the vehicle is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
R if there is a malfunction in the system or in
the voltage supply
R if Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
R if the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R if the battery is disconnected
R if the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
Further information about deactivating Active
Distance Assist DISTRONIC (Y page 142).
If Active Distance Assist DISTRONIC detects
that the vehicle in front is stopping, it brakes
your vehicle until it is stationary. 140
Driving syste
msDriving and parking
Page 143 of 298
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending 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 electric parking brake is applied automati-
cally if Active Distance Assist DISTRONIC is
active when the vehicle is stationary and:
R the driver's seat belt is not fastened and the
driver's door is open
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
R a system malfunction occurs
R the power supply is insufficient
If a malfunction occurs, the transmission may
also shift to position 005Dautomatically.
Setting a speed X
Press the cruise control lever up 0043for a
higher speed or down 0044for a lower speed.
X To adjust the set speed in 1 mph incre-
ments (1 km/h increments):
briefly press
the cruise control lever up 0043or down 0044to
the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044the last speed stored is
increased or reduced.
X To adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly pressthe cruise control lever up
0043or down 0044
beyond the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044, the last speed stored is
increased or reduced.
i If you accelerate to overtake, Active Dis-
tance Assist DISTRONIC adjusts the vehicle's
speed to the last speed stored after you have
finished overtaking.
Setting a specified minimum distance You can set the specified minimum distance for
Active Distance Assist DISTRONIC by varying
the time span between one and two seconds.
This determines the distance that Active Dis-
tance Assist DISTRONIC is to maintain from the
vehicle in front, depending on the road speed.
You can see this distance in the multifunction
display (Y page 142).
i Make 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. X
To increase: turn control0044in direction 0087.
Active Distance Assist DISTRONIC then main- tains a greater distance between your vehicleand the vehicle in front.
X To decrease: turn control0044in direction 0043.

Tips for driving with Active Distance
Assist DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, going into and coming out of a
bend
R Vehicles traveling on a different line
R Other vehicles changing lanes
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary. Active
Distance Assist DISTRONIC will then be deacti-
vated. Cornering, going into and coming out of a
bend The ability of Active Distance Assist DISTRONIC
to detect vehicles when cornering is limited.
Your vehicle may brake unexpectedly or late.
Vehicles traveling on a different line Active Distance Assist DISTRONIC may not
detect vehicles that are not driving in the middle of their lane. The distance to the vehicle in frontwill be too short.
Other vehicles changing lanes Active Distance Assist DISTRONIC has not
detected the vehicle cutting in yet. The distance
to this vehicle will be too short. Driving syste
ms
143Driving an d parking Z
Page 146 of 298
Narrow vehicles
Active Distance Assist 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 Active Distance Assist 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 revealed, Active Distance Assist DISTRONIC will not brake
for them.
Crossing vehicles Active Distance Assist DISTRONIC may mistak-
enly detect vehicles that are crossing your lane. Activating Active Distance Assist DISTRONIC at,
for example, a traffic light with crossing traffic
could cause your vehicle to pull away at the
wrong time. HOLD
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G

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:
R switch on the ignition
R shift the transmission to position 005B,005Eor
005C
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:
R below the detection range, e.g. people, ani-
mals or objects.
R above the detection range, e.g. overhanging
loads, truck overhangs or loading ramps. 148
