2015 MERCEDES-BENZ S-Class automatic transmission

!
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 other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R shift the transmission to position D,Ror N
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors General notes
PARKTRONIC does not take objects into con-
sideration that are:
R below the detection range, e.g. people, ani-
mals or objects.
R above the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps. :
Sensors in the front bumper, left-hand
side (example) The sensors must be free from dirt, ice or
slush. They can otherwise not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them

the minimum, the distance may no longer be
shown.

The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is in the
instrument cluster. The warning display for
the rear area is located on the headliner in the
rear compartment.
The warning display for each side of the vehi- cle is divided into five yellow and two red seg-
ments. PARKTRONIC is operational if opera-

Driving systemsDriving and parking

:

; Parking symbol
= Detected parking space on the right
Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i Note that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a status indicator in the instrument cluster.
When a parking space has been detected, an arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv- er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain switched on until you acknowledge the use of
Active Parking Assist by pressing the a
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it.
Pa rking G
WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
R there is a malfunction in the system or in
the voltage supply.
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.
Before leaving the vehicle, always secure it
against rolling away.
i When PARKTRONIC detects obstacles,
Active Parking Assist brakes automatically
during the parking process. You are respon- sible for braking in good time.

that it is already possible to pull out of the
parking space.

addition, a lane with lane markings on both
sides must be recognized.
In the case of a broken lane marking being
detected, a lane-correcting brake application can only be made if a vehicle has been detec-
ted in the adjacent lane. Oncoming vehicles,
overtaking vehicles and vehicles in adjacent
lanes can be detected.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake or
accelerate.
R you cut the corner on a sharp bend.
R you have switched on the turn signal.
R a driving safety system intervenes, e.g.

R a loss of tire pressure or a defective tire has
been detected and displayed.
R an obstacle in the lane in which you are
driving has been detected.
Active Lane Keeping Assist may not detect
other road users or traffic situations. An inap- propriate brake application may be interrup-
ted at any time if you:
R steer slightly in the opposite direction
R switch on the turn signal
R clearly brake or accelerate

Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRIDmode, the hybrid
system automatically selects the most effi-
cient operating mode for every driving situa-
tion. Drive the vehicle in the usual manner.
To save fuel, in HYBRIDmode, the hybrid
system switches off the combustion engine
as often as possible during the journey when power output requirements are low. When
power output requirements are low, the elec-
tric motor powers the vehicle. The engine is
switched on, even while the vehicle is in
motion, when a higher power output is
required. The engine is usually switched off when the vehicle is stationary. Consequently,
there is usually no engine idling as with com-
bustion engine vehicles.
For pulling away and accelerating, the electric motor supports the internal combustion
engine using the power stored in the high-
voltage battery. This energy is also used for
driving in partially electric mode, to operate
the electric refrigerant compressor and sup-
port the 12 V on-board electrical system. In
this way the hybrid drive helps to reduce your
vehicle's fuel consumption.
Observe the driving tips on PLUG-IN HYBRID
operation (Y page 287).
Recuperative Brake System If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is
initiated. The electric motor is operated as a
generator when in overrun mode and when
you brake. Hybrid technology converts the
kinetic energy of the vehicle into electricity
and stores it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (Y page 48). Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
R a message appears in the multifunction dis-
play and
R a warning tone sounds
Further information (Y page 340).
All of the vehicle's systems remain active, if:
R the vehicle is stationary
R the combustion engine is switched off and
R the READY indicator in the instrument clus-
ter lights up
If you remove your foot from the brake pedal
while in transmission position D or R, the
vehicle may pull away automatically.
Observe the notes on the READY display of
the ECO start/stop function (Y page 288).276

The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only
after the power demanded by the driver
exceeds the available power that the electric motor can currently provide.
Noiseless start operation is dependent on the
outside temperature and the operating tem-
perature of the internal combustion engine. If
not all conditions for noiseless start operation are fulfilled, the vehicle starts with the inter-
nal combustion engine. X
