Automatic drive program
Automatic drive program E (C) Drive program E (drive program C on Mercedes-
AMG vehicles) is characterized by the following: R
comfort-oriented engine and automatic trans-
mission settings. R
optimal fuel consumption resulting from the
automatic transmission shifting up sooner. R
the vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
pedal is depressed fully. R
the vehicle has improved driving stability, for
example on slippery road surfaces. R
the automatic transmission shifting up
sooner. This results in the vehicle being driven
at lower engine speeds and the wheels being
less likely to spin. Automatic drive program S Drive program S (or, in the case of Mercedes-
AMG vehicles, drive programs S and S+ ) is char-
acterized by the following: R
sporty engine and automatic transmission
settings. R
the automatic transmission shifts up later.
The fuel consumption possibly being higher
as a result of the later automatic transmission
shift points.
Manual drive program M General notes In this drive program, you can briefly change
gear yourself by using the steering wheel paddle
shifters. The transmission must be in position D .
You can activate manual drive program M in
automatic drive programs E , C and S .
Mercedes-AMG vehicles and vehicles with
AMG sports package: as well as temporary
drive program M you can also activate perma-
nent drive program M ( Y

Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.

i The text shown in the multimedia system
depends on the language setting. The follow-
ing are examples of rear view camera displays
in the multimedia system.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in which
you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner: R
if the trunk lid is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the camera is exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) R
if there is a sudden change in temperature,
e.g. when driving into a heated garage in win-
ter R
if the camera lens is dirty or obstructed
Observe the notes on cleaning
( Y
page 274)R
if the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on tech-
nical conditions.
i The rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens.
The flap closes again when: R
you have finished the maneuvering process R
you switch off the engine R
you open the trunk
Observe the notes on cleaning ( Y
page 274).
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated. Switching the rear view camera on/off X
To switch on: make sure that the Activa‐
tion by R gear function is selected in the
multimedia system (see Digital Operator's
Manual). X
Engage reverse gear.
The rear view camera flap opens. The multi-
media system shows the area behind the vehi-
cle with guide lines.
The image from the rear view camera is avail-
able throughout the maneuvering process. X
To switch off: shift the transmission to posi-
tion P .

Drive forwards a short distance.
Displays in the multimedia system The rear view camera may show a distorted view
of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions: R
very close to the rear bumper R
under the rear bumper R
in the area immediately above the tailgate
handle
! Objects not at ground level may appear to
be further away than they actually are, e.g.: R
the bumper of a parked vehicle R
the drawbar of a trailer R
the ball coupling of a trailer tow hitch R
the rear section of an HGV R
a slanted post
