2015 MERCEDES-BENZ S-CLASS COUPE steering

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.

General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep
slopes
R when manoeuvring 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 cancelled and the HOLD function is deactivated when you depress theaccelerator pedal to pull away. Driving systems
205Driving and parking Z

When the HOLD function 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 the HOLD function is activa-
ted, 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. MAGIC BODY CONTROL
General notes MAGIC BODY CONTROL consists of Active
Body Control (ABC), ROAD SURFACE SCAN,
the CURVE cornering function as well as auto-
matic vehicle stabilisation in the event of a
crosswind.
Your vehicle automatically adjusts its ride
height to reduce fuel consumption. The sus-
pension mode is adjusted according to your
selection (SPORT, COMFORT or CURVE), the
road surface conditions and the vehicle load. A multifunction camera detects bumps in the
road surface before the vehicle drives over
them. This reduces chassis movements.
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.
Crosswind Assist The crosswind stabilisation operates by
changing wheel loads through distortion of
the ABC spring struts. It reduces impairments
in handling when driving in a straight line andassists during countersteering.
Crosswind Assist is active in the speed range
between 80 km/h and 210 km/h when driv-
ing straight ahead or cornering gently.
Active Body Control ABC Vehicle level
All vehicles except AMG vehicles:
depend-
ing on the vehicle level that has been set, the vehicle automatically adjusts its height
dependent on the current speed. The vehicle
is lowered by up to 15 mm as the speed
increases. As the speed is reduced, the vehi- cle is raised to the set vehicle height.
In the event of poor road surface conditions,
the vehicle automatically raises by up to
10 mm and harder damping is selected.
AMG vehicles: depending on the vehicle
level that has been selected, the vehicle auto-
matically adjusts its height dependent on the current speed. The vehicle is lowered by up to
10 mm below the normal level as the speed
increases. As the speed is reduced, the vehi-
cle is raised to the set vehicle height.
Select the "Normal" setting for normal road
conditions and "Raised" for driving with snow chains or on particularly poor road condi-
tions.
Your selection remains stored even if you
remove the key from the ignition lock.
The "Raised level" setting is cancelled if you:
R are driving faster than approximately
120 km/h
R drive for approximately three minutes at a
speed above 80 km/h Driving systems

Suspension setting
The electro-hydraulically controlled ABC sus- pension system works continuously. This
improves driving safety and comfort. The sys- tem detects the vehicle level and the vehicle
load and adjusts the setting accordingly. You
can also choose between a particularly sporty
mode (SPORT), a comfortable mode (COM- FORT), as well as a comfortable mode with
cornering function (CURVE).
The ABC suspension system is tuned individ-
ually to each wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sporty or com-
fort or comfort with the CURVE dynamic
cornering function
R the vehicle load
R the force of the side wind
Your selection remains stored even if you
remove the key from the ignition lock. The firmer suspension setting in SPORT mode
ensures even better contact with the road.
The steering response behaviour is sporty.
Select this mode on winding country roads or
motorways, for example.

the road in front of the vehicle using a multi-
function camera :at the top of the wind-
screen. This function is automatically active if
you select comfort suspension tuning. The
system is operational at speeds of up to
130 km/h.

lights up. PARKTRONIC has malfunctioned and has switched off.
X If problems persist, have PARKTRONIC checked at a qualified
specialist workshop. Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X Clean the PARKTRONIC sensors (Y page 349).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X See if PARKTRONIC functions in a different location. Active Parking Assist
General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use
PARKTRONIC (Y page 212).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is deactivated, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions.
R in front of driveways or entrances and exits.
R unsuitable surfaces. Driving systems
215Driving and parking Z

Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 214) warning messages during the
parking procedure.
R you can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends.
R on the same level as the road, e.g. not on
the pavement.
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection
range (Y page 213).
Active Parking Assist does not assist you
parking in spaces at right angles to the direc-
tion of travel if:
R two parking spaces are located directly
next to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward park
Active Parking Assist does not assist you
parking in spaces that are parallel or at right
angles to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer 216
