The automatic transmission changes
gear automatically in the automatic
drive programs (Y page 122). All
forward gears are available. Driving tips
Changing gear The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position 005B. This automatic gear shift-
ing behavior is determined by:
R the selected drive program (Y page 116)
R the position of the accelerator pedal
R the road speed
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
A dynamic driving style with high longitudinal
and lateral acceleration delays the shift points
to higher engine speeds. Double-clutch function When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function
reduces load change reactions and is conducive to a sporty driving style. The sound generated by
the double-clutch function depends on the drive program selected.
Kickdown Use kickdown for maximum acceleration:
X In the automatic drive programs, depress the
accelerator pedal beyond the pressure point.
Depending on the engine speed and the selec- ted drive program, the automatic transmis-
sion shifts to the lowest gear permissible to
give optimal acceleration.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Kickdown is not available in manual mode M.
Rocking the vehicle free Rocking the vehicle free may help to free the
vehicle if it has become stuck in slush or snow. To do so, shift back and forth repeatedly
between transmission positions 005Band 005E.
The vehicle's transmission management
restricts shifting between transmission posi-
tions 005Band 005Eto speeds up to a maximum of
5 mph (9 km/h).
To shift back and forth between transmission
positions 005Band 005E, move the E-SELECT lever
up and down beyond the pressure point.
Gliding mode 120
AMG SPEEDSHIFT DCT 7-speed sports transmissionDriving an
d parking

Gliding mode is characterized by the following:
R the combustion engine is disconnected from
the drive train.
R the engine speed corresponds to the idling
speed.
R the Csymbol disappears from the multifunc-
tion display and symbol 0043is displayed
(Y page 119).
In drive program C, you can deactivate and acti-
vate gliding mode using the ECO button
(Y page 114).
Gliding mode can be activated under the follow-
ing conditions:
R the speed is within a suitable range.
R the course of the road is suitable, e.g. there
are no steep up or downhill gradients.
R you are no longer depressing the accelerator
pedal.
Gliding mode is deactivated under the following conditions:
R you depress the accelerator pedal.
R you depress the brake pedal.
R you switch the transmission position using
the E‑SELECT lever (Y page 117).
R you switch to drive program RACE
(AMG GT C Roadster), S+orS(Y page 116).
R you switch to manual mode M(Y page 121).
R you leave the suitable speed range.
i If you have selected the "Comfort" setting
for the drive (engine management) in drive
program I, you can also activate gliding mode.

RACE drive program (AMG GT C Road-
ster) The RACE drive program is designed for maxi-
mum performance in terms of shift points and engine speeds. The engine and transmission
should be at normal operating temperature for
the RACE drive program (Y page 170). Use the
RACE drive program on a closed-off race circuit.
The RACE drive program is characterized by the
following:
R the vehicle exhibits driving characteristics
suitable for the racetrack.
R all vehicle systems are set for maximum
sportiness.
R for optimum performance, the transmission
shifts up later and shifts down sooner.
R the multifunction display shows the manual
gearshift program without upshift indicator
(Y page 122).
R the gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (Y page 123). You can follow the
gearshift recommendations at all times and
shift gear accordingly using the steering
wheel paddle shifters. On the basis of the
gearshift recommendation, using the steering wheel paddle shifters, you can optimize the
drive train and engine operating mode at any
time.
R if you have selected a gear manually, this will
be maintained until the vehicle speed increa-
ses or decreases dramatically.
R if you do not follow the gearshift recommen-
dations, the automatic shift points may result
in high fuel consumption.
R the suspension exhibits particularly hard
springing and damping settings.
R the transmission shift and response times are
significantly shorter with more aggressive
gear changes. This is particularly the case
when shifting up. The shift strategy is thus
designed to interact dynamically with the
high-revving engine.
R gliding mode is not available.
R the ECO start/stop function is not available. 124
