Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving on an unpaved road or off-road,
check the vehicle underside regularly. In par-
ticular, remove trapped plant parts or other
flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected. G
WARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb, a speed bump or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the loads they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop. Declarations of conformity

You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the selected equipment.
These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to the vehicle (e.g. smartphone, USB memory stick
or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R General vehicle information
R Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of
the app being used. Whether you can configure settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem. Online services
Wireless network connection If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi-
cle and other systems. The wireless network
connection is made possible by the vehicle's
own transmitter and receiver or by mobile devi- ces that you have brought into the vehicle (e.g.
smartphones). Online functions can be used via
this wireless network connection. These include online services and applications/apps providedby the manufacturer or other providers.
Services provided by the manufacturer In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place (e.g. operating instructions,
manufacturer's website) and provides the asso-
ciated information subject to data protection
legislation. Personal data can be used in order to
provide online services. The exchange of data
for this purpose takes place via a secure con-
nection, e.g. with the manufacturer's IT systems intended for the purpose. Collecting, processing
and using personal data beyond the provision of
services is permitted only on the basis of a stat-
utory permit or declaration of consent.
You can usually activate and deactivate the serv-
ices and functions (sometimes subject to a fee).
In many cases, this also applies to the vehicle's entire data connection. However, this does not
apply in particular to legally prescribed func-
tions and services such as the "eCall" emer-
gency call system.
Services from third parties If it is possible to use online services from other
providers, these services are the responsibility
of the provider in question and subject to that
provider's data protection conditions and terms of use. The manufacturer has no influence over
the content exchanged here.
For this reason, please ask the service provider
for information about the type, extent and pur-
pose of the collection and use of personal data
when services are provided by third parties. 30

0044 Neutral
Do not shift the transmission to
005C
while driving. The automatic trans-
mission could otherwise be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow you to
move the vehicle freely, e.g. to push
it or tow it.
If ESP ®
is deactivated or faulty: shift
the transmission to position 005Cif the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch off the engine using the SmartKey or the Start/Stop button,
the automatic transmission shifts to
neutral 005Cautomatically.
! Coasting in neutral
005Cmay
cause damage to the drive train. 003A Drive
The automatic transmission changes
gear automatically in the automatic
drive programs (Y page 122). All
forward gears are available. Driving tips
Changing gear The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position 005B. This automatic gear shift-
ing behavior is determined by:
R the selected drive program (Y page 116)
R the position of the accelerator pedal
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts
A dynamic driving style with high longitudinal
and lateral acceleration delays the shift points
to higher engine speeds. Double-clutch function When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function
reduces load change reactions and is conducive to a sporty driving style. The sound generated by
the double-clutch function depends on the drive program selected.
Kickdown Use kickdown for maximum acceleration:
X In the automatic drive programs, depress the
accelerator pedal beyond the pressure point.
Depending on the engine speed and the selec- ted drive program, the automatic transmis-
sion shifts to the lowest gear permissible to
give optimal acceleration.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Kickdown is not available in manual mode M.
Rocking the vehicle free Rocking the vehicle free may help to free the
vehicle if it has become stuck in slush or snow. To do so, shift back and forth repeatedly
between transmission positions 005Band 005E.
The vehicle's transmission management
restricts shifting between transmission posi-
tions 005Band 005Eto speeds up to a maximum of
5 mph (9 km/h).
To shift back and forth between transmission
positions 005Band 005E, move the E-SELECT lever
up and down beyond the pressure point.
Gliding mode 120
AMG SPEEDSHIFT DCT 7-speed sports transmissionDriving an
d parking

Gliding mode is characterized by the following:
