Manual gear shifting
General notes You can change gear yourself using the steering
wheel paddle shifters. The transmission must be
in position D .
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: R
temporary setting R
permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D .
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporary setting X
To activate: shift the DIRECT SELECT lever to
position D . X
Pull steering wheel paddle shifter C or D .

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 a risk of engine damage.
X
To shift up: pull steering wheel paddle
shifter D .
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. X
To shift down: pull steering wheel paddle
shifter C .
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 protects against 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. X
Shift to recommended gear D according to
gearshift recommendation C when shown in
the multifunction display.
Upshifting (Mercedes-AMG vehicles)
! The automatic transmission does not shift
up automatically even when the engine limit-
ing 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 a risk of
engine damage.136

Before the engine speed reaches the red area,
an upshift indicator will be shown in the multi-
function display. X
Shift to recommended gear C when mes-
sage D is shown in the multifunction display.
Kickdown X
For maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed. X
Shift back up once the desired speed is
reached. During kickdown, you cannot shift gears using
the steering wheel paddle shifters.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving.
Mercedes-AMG vehicles: it is only possible to
use kickdown in temporary manual drive pro-
gram M . When manual drive program M is per-
manently activated, kickdown is not possible.

incorrectly, there is a risk of fire and explo-
sion. You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
G WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury. Refueling 137
Driving and parking Z

You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay. R
If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing. R
