Neutral
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:
only shift the transmission to posi-
tion N if the vehicle is in danger of
skidding, e.g. on icy roads.
When you switch off the engine, the
automatic transmission automati-
cally shifts into neutral N.7
Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Changing gear
The
automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. Gearshifting is deter-
mined by:
R the selected drive program ( Y page 155)
R the position of the accelerator pedal
R the road speed Driving tips
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
Holding

the vehicle stationary on uphill
gradients G
WARNING
If the clutch overheats, the electronic man-
agement
system is automatically deactivated. This interrupts the power transmission. The
vehicle may, for example, roll backwards on
gradients. There is a risk of an accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The

clutch may overheat if you hold the vehi-
cle stationary on uphill gradients by depress-
ing the accelerator pedal. If the clutch over-
heats, a warning tone sounds.
All vehicles (except AMG vehicles): the
Stop vehicle Shift to P Leave engine
running display message appears in the mul-
tifunction display. You will only be able to
continue your journey once the clutch has
cooled down and the display message in the
multifunction display has disappeared.
AMG vehicles: the Trans. oil overhea‐
ted Drive on with care display message
appears in the multifunction display.
Do not hold the vehicle stationary on uphill
gradients by depressing the accelerator
pedal. Instead, only ever hold the vehicle sta-
tionary on uphill gradients by:
R depressing the brake pedal
R activating the HOLD function
R engaging the electric parking brake
Kickdown AMG vehicles:
it
is only possible to use kick-
down in temporary manual drive program M.
For further information on the manual drive
program M, see ( Y page 156).
Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.

In drive program M, you can change gear
yourself using the steering wheel gearshift
paddles.
If
you pull the left or right steering wheel gear-
shift paddle when in automatic drive program
E (drive program C on AMG vehicles) or S, the
automatic transmission shifts into drive pro-
gram M for a limited time. Depending on
which gearshift paddle is pulled, the auto-
matic transmission immediately shifts into
the next gear down or up.
AMG vehicles: you can activate drive pro-
gram M RACE START (Y page 181) using the
steering wheel gearshift paddles.
i You can only change gear with the steer-
ing wheel gearshift paddles when the trans-
mission is in position D.
i For further information on the manual
drive program, see ( Y page 156).Automatic drive program
Drive program E (drive program C on AMG
vehicles) is characterised by the following:
R comfort-oriented engine settings.
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner. R
the vehicle pulling away more gently in
forward

and reverse gears unless the accel-
erator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.
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.
Drive program S is characterised by the fol-
lowing:
R sporty engine settings.
R the automatic transmission shifting up
later.
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos-
sibly being higher. Manual drive program
Introduction In manual drive program
M, you can change
gear yourself by using the steering wheel
gearshift paddles. For this, the transmission
must be in position D. The gear currently
selected and engaged is shown in the multi-
function display.
Manual drive program M differs from drive
programs E (drive program C on AMG vehi-
cles) and S with regard to spontaneity,
responsiveness and smoothness of gear
changes. Gear Driving situations

i All vehicles (except AMG vehicles): in
order to prevent engine damage the auto-
matic

transmission automatically shifts up:
R if the maximum engine speed on the cur-
rently engaged gear is reached and
R you depress the accelerator pedal.
AMG vehicles:
! In manual gearshift program M, the auto-
matic transmission does not shift up auto-
matically even when the engine limiting
speed for the current gear is reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. You must make sure that
the engine speed does not reach the red
area of the rev counter. Otherwise, there is
a risk of engine damage.
