Manual gear shifting
General notes
You can change gear yourself using the steering wheel paddle shifters. The transmission must be
in position hto do this.
Depending on which steering wheel paddle
shifter is pulled, the automatic transmission
immediately shifts into the next gear down or
up, if permitted. Mercedes-AMG vehicles:
to use manual shift-
ing, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position h.
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporar ysetting
XTo activate: shift the DIRECT SELECT lever to
position h.
XPull steering wheel paddle shifter :or;.
Temporary setting will be active for acertain
amount of time. Under certain conditions the
minimum amount of time is extended, e.g. in the case of lateral acceleration, during an overrun
phase or when driving on steep terrain.
XTo deactivate: pull steering wheel paddle
shifter ;and hold it in place.
or
XUse the DIRECT SELECT lever to switch the
transmission position.
or
XAll vehicles (except Mercedes-AMG vehicles):
use the DYNAMI CSELECT button to change
the drive program.
Mercedes-AMG vehicles: use the DYNAMIC
SELECT controller to change the drive pro-
gram.

Shifting gears
!Mercedes-AMG vehicles: the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim-
iting speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the tachometer. There is
otherwise arisk of engine damage.
XTo shift up: pull steering wheel paddle
shifter ;.
The automatic transmission shifts up to the
next gear. All vehicles (except Mercedes-AMG vehi-
cles):
if the maximum engine speed on the
currently engaged gear is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up in order to
prevent engine damage.
XTo shift down: pull steering wheel paddle
shifter :.
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when coast-
ing.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protectsa gainst engine damage
by not shifting down.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display.
XShift to recommended gear ;according to
gearshift recommendation :when shown in
the multifunction display.
Upshifting (Mercedes-AMG vehicles)
!In manual mode, the automatic transmis-
sion does not shift up automatically 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. Always
make sure that the engine speed does not
reach the red area of the tachometer. There is
otherwise arisk of engine damage.

Kickdown
XFor maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to alower
geard epending on the engine speed.
XShift back up once the desire dspeed is
reached. During kickdown, yo
ucannot shift gears using
the steering wheel paddl eshifters.
If yo uapply fullthrottle ,the automatic trans-
missio nshifts up to the next gearw hent he
maximum engine speed is reached.T hispre-
vents the engine from overrevving.
Mercedes-AMG vehicles: it is only possible to
use kickdown in temporary manual drive pro-
gram M.Whenm anual drive program Mis per-
manently activated, kickdown is not possible.

Always touc hthe vehicle body beforeo pening
the fuel filler flap or touching the fuel pump
nozzle. An yexisting electrostatic buildup is
thereby discharged.
!Do not use diesel to refuel vehicles with a
gasolinee ngine. Do not switc honthe ignition
if you accidentally refuel with the wrongf uel.
Otherwise, the fuel will enter the fuel system. Even small amount softhe wrongf uel could
result in damage to the fuel syste mand the
engine. Notify aqualified specialis tworkshop
and have the fuel tan kand fuel lines drained
completely.
!Overfilling the fuel tan kcould damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use afilter when adding fuel from afuel can.
The fuel lines and/or the fuel injection system
could otherwise be blocked by particles from
the fuel can. Do not get int
othe vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
