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 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.

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.
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. 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 tothe speed you have stored.
Selecting the drive program
All vehicles (except AMG vehicles):
DISTRONIC PLUS supports a sporty driving
style when you select the Sdrive program
(Y page 173). Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. If you have selected the E
drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
and-start traffic.
AMG vehicles: DISTRONIC Plus supports a
sporty driving style when you select the Sor
M drive program (Y page 173). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. When you
select the Cdrive program, the vehicle accel-
erates more gently. This setting is recom-
mended 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 right lane (on left-hand-
drive vehicles) or the left lane (on right-
hand-drive vehicles).
Road and traffic conditions i
The following function is not operational
in all countries.
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. 198
Driving systemsDriving and pa
rking

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.
Further information on deactivating
DISTRONIC PLUS (Y page 201).
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.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion Pif:
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
The electric parking brake secures the vehicle automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position Pautomatically.

increments: briefly press the cruise con-
trol lever up :or down ;beyond the
pressure point.
The last stored speed increases or decrea- ses in 10 km/h increments.
i If you accelerate 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 between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(Y page 200).
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
To increase: turn control;in direction
=.
DISTRONIC PLUS then maintains a greater distance between your vehicle and the
vehicle in front.
X To decrease: turn control;in direc-
tion :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front.
