WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or on a
downhill gradient
R the transmission is in position 005C
R the electric parking brake is applied
R ESP ®
is malfunctioning Rear axle steering
General notes Depending on the speed, rear axle steering
adapts the track of the rear axle to the position
of the front wheels. Together with the steering
angle of the front wheels, this results in greater mobility and stability than on vehicles without
rear axle steering.
Rear axle steering has the following character-
istics:
R reduced steering effort and turning circle,
resulting in reduced parking effort.
R improved driving stability, e.g. on curves.
R the vehicle has more direct steering. Control
of the vehicle is thereby increased. ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle. Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.

Temporary manual drive program General notes
In this drive program, you can briefly change
gear yourself by using the steering wheel paddle shifters. The transmission must be in position
005B to do this.
You can activate the temporary manual drive
program in the automatic drive program. The
switching times correspond to the previously
active automatic drive program.
In addition to temporary manual drive program
you can also activate manual mode M
(Y page 123).
Activating X
Shift the transmission to position 005B.
X Pull the left-hand or right-hand steering wheel
paddle shifter (Y page 121).

X When the corresponding gearshift recom-
mendation 0043appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear 0044.
Display for shift override If the engine speed becomes too high or too low
as a result of shifting gear, you cannot shift gear
using the steering wheel paddle shifters. If you
then pull the left-hand or right-hand steering
wheel paddle shifter, segments 0043light up red
briefly.
Downshifting X
Pull the left-hand steering wheel paddle
shifter (Y page 121).
In cases where it is permissible, the automatic transmission shifts down to the next gear.
X Maximum acceleration: pull the left-hand
steering wheel paddle shifter until the trans-
mission selects the optimum gear for the cur- rent speed.
If you slow down or stop without shifting down,
the automatic transmission automatically shifts down.
Deactivating X
Press the M button (Y page 121).
The indicator lamp in the button goes out.
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
