Activating DISTRONIC PLUS Activation conditions
To activate DISTRONIC PLUS, all of the fol-
lowing activation conditions must be fulfilled:
R the engine must be running. It may take up
to two minutes of driving before DIS-
TRONIC PLUS is ready for use.
R the electric parking brake must be
released.
R ESP ®
must be switched on, but not inter-
vening.
R Active Parking Assist must not be activa-
ted.
R DSR must be deactivated.
R the transmission must be in position D.
R the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door and the rear
doors must be closed.
R the DISTRONIC PLUS function must be
selected with the cruise control lever
(Y page 195). Activating
X Briefly pull the cruise control lever towards
you ?or press it up :or down A.
DISTRONIC PLUS is activated.
X Keep the cruise control lever pressed up :
or down Auntil the desired speed is set.
X Remove 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.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS inactive DISTRONIC PLUS inactive
message appears in the multifunction dis-
play. The set distance to a slower-moving
vehicle in front will then not be maintained. You will be driving at the speed you deter-
mine by the position of the accelerator
pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is 30 km/h.
X Briefly pull the cruise control lever towards
you ?or press it up :or down A.
DISTRONIC PLUS is activated.
Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever
(Y page 194) towards you ?.
X Remove your foot from the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is Driving systems

stored. Otherwise, it sets the vehicle cruise
speed to the previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving
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.
DISTRONIC PLUS is deactivated when you
depress the brake, except when the vehicle is
stationary.
X If you want to pull away with DIS-
TRONIC PLUS: remove your foot from the
brake pedal.
X Briefly pull the cruise control lever
(Y page 194) 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 vehi-
cle accelerates to the set speed.
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.
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 S or M driv- ing program (Y page 171). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the E driving 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, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
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.
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 DIS-
TRONIC PLUS (Y page 198).
If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. 196
Driving systemsDriving and parking

Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a short period, the vehicle is secured
by the electric parking brake, thus relieving
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 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
R a system fault occurs
R the power supply is insufficient
If a malfunction occurs, then the transmission may also be shifted into position Pautomat-
ically.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to the set speed. :

sure point.
The last stored speed increases or decrea- ses in 10 km/h increments.
i DISTRONIC PLUS is not deactivated if you
depress the accelerator pedal. If you accel-
erate to overtake, DISTRONIC PLUS
adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking.
Setting the specified minimum distance You can set the specified minimum distance
for DISTRONIC PLUS by varying the time span Driving systems
197Driving and parking Z

between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(Y page 199).
i Make sure that you maintain the mini-
mum distance to the vehicle in front as
required by law. Adjust the distance to the vehicle in front if necessary. X

4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot Driving systems
203Driving and parking Z

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 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. DSR
Important safety notes i
DSR (Downhill Speed Regulation) is only
available for vehicles with the Off-Road
Engineering package.
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
non-existent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D, Ror N. By accelerating or braking, you can
always drive at a higher or a lower speed than
that set on the on-board computer.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor over-
ride the laws of physics. DSR cannot take account of road, weather and traffic condi-
tions. DSR 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 lane.
You are always responsible for keeping con-
trol of the vehicle and for assessing whether
the downhill gradient can be managed. DSR
may not always be able to keep to the set
speed, depending on road surface and tyre
conditions. Select a set speed suitable for theprevailing conditions and when necessary,
apply the brakes manually. G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
For information about driving off-road, see
(Y page 185).
Activating/deactivating DSR G
WARNING
If you drive faster than the set speed and acti-
vate DSR, the vehicle will decelerate on down- hill gradients. If you do not know the set
speed, the vehicle could decelerate unexpect-edly. There is a risk of an accident.
Decelerate the vehicle to the set speed before
activating DSR. If you do not know what the
stored set speed is, store the desired set
speed again.
Activating
You can only activate DSR when driving at
speeds below 30 km/h. 204
