2015 MERCEDES-BENZ S-CLASS COUPE Owners Manual

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.

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.

Tips for driving with DISTRONIC PLUS General notes
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
lane. The distance to the vehicle in front will
be too short.
Other vehicles changing lane202
Driving systemsDriving an
d parking

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 carriage-
way, because of its narrow width. The dis-
tance 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.
In a speed range from 0 - 60 km/h, Stop&Go
Pilot focuses on the vehicle in front, taking
into account lane markings, e.g. when follow- ing vehicles in a traffic jam.
At speeds of more than 60 km/h, Steering
Assist focuses on detected lane markings Driving systems
203Driving and parking Z

(left and right), only focusing on the vehicle in
front if detected lane markings are not pres-
ent.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide
assistance.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of
an accident nor override the laws of physics. It cannot take into account road, weather or
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilot 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.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traf-
fic conditions and does not detect all road
users. If you are following a vehicle which is
driving towards the edge of the carriageway,
your vehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane. The support offered by the system may be
impaired if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
in the vicinity of the camera
R no or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel
or do not steer for a prolonged period of
time
i After you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again.
Steering Assist and Stop&Go Pilot cannot
provide assistance:
R on very sharp corners
R a loss of tyre pressure or a defective tyre
has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 195).204
Driving systemsDriving and parking

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 you have 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
remains active.
