X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is
stored. Otherwise, it sets the vehicle cruise speed to the previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving
X
If you want 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.
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 vehicle then brakes automatically. There is
a risk of an accident. Be ready to brake at all
times.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is maintained.
If DISTRONIC PLUS 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
DISTRONIC PLUS supports a sporty driving
style when you have selected the Sor S+
drive program (Y page 197). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the Cor Edrive program, the vehicle
accelerates more gently. This setting is rec-
ommended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane,
DISTRONIC PLUS supports you if:
R you are driving faster 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 is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in front becomes too small.
i When you change lanes, DISTRONIC
PLUS monitors the left lane (on left-hand-
drive vehicles) or the right lane (on right-
hand-drive vehicles). Driving systems

Road and traffic conditions
i
The following function is only available in
vehicles with the Driving Assistance Plus
package.
The function is not operational in all coun-
tries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
adapt to certain traffic situations. This is the
case if, while following a vehicle, 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
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does not accelerate. 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 above 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles
in the adjacent lane to the left.
i Prevention of overtaking on the right
applies to countries where traffic drives on
the right. In countries where traffic drives
on the left, overtaking on the left is preven-
ted accordingly. Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS (Y page 228).
If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
After a short period, the vehicle is secured by
the electric parking brake, thus relieving the
service brake.
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 secures the vehicle
automatically if DISTRONIC PLUS is activated
and:
R the seat belt is unfastened 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 226

Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend
R Vehicles which are not driving in the middle
of their lane
R Other vehicles changing lane
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, entering and exiting a bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles which are not driving in the mid- dle of their lane DISTRONIC PLUS may not detect vehicles
which are not driving in the middle of their Driving systems

lane. The distance to the vehicle in front will
be too short.
Other vehicles changing lane DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle will be too short.
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.
Obstructions 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.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
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
moderate steering interventions in a speed
range from 0 - 200 km/h.
It monitors the area in front of your vehicle by means of camera system :at the top of the
windscreen. 230
Driving systemsDriving and parking

Also observe the important safety notes for
DISTRONIC PLUS (Y page 222).
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 sym-
bol appears in the multifunction display. If youhave still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot
switch to passive mode. DISTRONIC PLUS

General notes AIRMATIC is an air suspension system with
variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. There is also the option to manually adjust the vehicle level.
AIRMATIC consists of level setting, level con-
trol and the Adaptive Damping System ADS.
Vehicles with automatic transmission: the
vehicle level can be set using the AGILITY
SELECT switch (Y page 197) or the level but-
ton (Y page 234). The setting always corre-
sponds to the last selected function.
Vehicles with manual transmission: the
vehicle level can be set using the AGILITY
SELECT switch (Y page 191) or the level but-
ton (Y page 234). The setting always corre-
sponds to the last selected function.
Important safety notes G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches.
i If one of the doors is open, the vehicle is
not lowered.
Vehicle level Setting the raised vehicle level
It is possible to choose between the "Normal"
and "Raised" vehicle levels below a speed of
80 km/h. Select the "Normal" setting for nor-
mal road surfaces and "Raised" for driving 234

override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in the lane.
If a drive wheel spins due to insufficient grip:
R when pulling away, only depress the accel-
erator pedal as far as is necessary
R accelerate less when driving
! Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain either on the 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 tyres (M+S tyres), with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a substi- tute for your attention to the immediate sur-
roundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
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
objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill, could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling.
PARKTRONIC is activated automatically if
you: R switch on the ignition
R shift the transmission to position D,Ror N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC is deactivated for the rear area when you establish an electrical connection
between your vehicle and a trailer.
Range of the sensors General notes
PARKTRONIC does not take into account
obstacles located:
R below the detection range, e.g. persons,
animals or objects
R above the detection range, e.g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles 236
