Shifting gears
XTo shift up: pull steering wheel paddle
shifter ;.
The automatic transmission shifts up to the
next gear.
If the maximum engine speed in the gear cur- rently engaged is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage (except Mercedes-AMG vehicles).
Mercedes-AMG vehicles: if the temporary
setting has been activated and you continue
to accelerate when the maximum engine
speed has been reached, the automatic trans- mission automatically shifts up. If the perma-
nent setting is activated, the automatic trans-
mission does not shift up automatically even
when the engine limiting speed for the current
gear is reached. Observe the protection
against reaching the overrevving range on the
multifunction display. Always make sure that
the engine speed does not reach the red area
of the tachometer.
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 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.
XWhen the corresponding gearshift recom-
mendation:appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear ;.
Protection against reaching the over-
revving range (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 a risk of engine damage.
Before the engine speed reaches the red area,
an upshift indicator will be shown in the multi-
function display.
XWhen message :appears in the multifunc-
tion display, pull on the right-hand steering
wheel paddle shifter.
Kickdown
XFor maximum acceleration, depress the
accelerator pedal beyond the pressure point. The automatic transmission shifts to a lower
gear depending on the engine speed.
XShift back up once the desired speed is
reached.
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: kickdown is only
possible in the temporary setting.

has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. otherwise electrostatic charge
could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system
could otherwise be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
