General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (Y page 70).
It is only possible to shift the transmission from position Pto the desired position, if:
R the engine is running and
R you depress the brake pedal
If you do not depress the brake pedal, the E-
SELECT lever can still be moved but the parking lock remains applied.
Information on automatically releasing the elec-
trical parking brake (Y page 122).
Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may 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. 104

Problem
Possible causes/consequences and
M
MSolutions The engine is not running
smoothly and is misfir-
ing. The engine electronics or a mechanical component of the engine
management system are/is malfunctioning.
X Depress the accelerator pedal only slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. The coolant temperature
display is showing more
than 120 †. A display
message may also
appear on the multifunc-
tion display and a warn-
ing tone may sound. The coolant level is too low. The coolant is too hot and the engine is not
being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 235). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty. The
coolant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECT controller

AMG SPEEDSHIFT DCT 7-speed sport trans
missionDriving and parking

Shifting gears
If you pull on the left or right-hand steering
wheel gearshift paddle, the automatic transmis-
sion switches to temporary manual drive pro-
gram for a limited amount of time. Depending on which gearshift paddle is pulled, the automatic
transmission immediately shifts into the next
gear up or down, if permitted.
X To shift up: pull the right-hand steering wheel
gearshift paddle (Y page 113).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed on the currently engaged gear is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage.
The automatic transmission will not shift up to
the next gear when the engine speed is very
low.
X To shift down: pull on the left-hand steering
wheel gearshift paddle (Y page 113).
The automatic transmission shifts down to
the next gear.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine damage by not shifting down.
Automatic downshifting occurs when coast-
ing.
When using kickdown, the automatic trans-
mission automatically shifts to a lower gear.
Deactivating If you have activated temporary manual drive
program, it will remain active for a certain
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.
When temporary manual drive program is deac-
tivated, the automatic transmission shifts into
the automatic drive program that was last selec-
ted. You can also deactivate temporary manual drive
program yourself:
X Pull on the right-hand steering wheel gearshift
paddle and hold it in place (Y page 113).
or
X Use the DYNAMIC SELECT controller to
change the drive program (Y page 108).
Temporary manual drive program is deactiva-
ted. The automatic transmission switches
into the automatic drive program that was last selected. Manual mode
General notes In manual mode
M, you can permanently change
gear yourself by using the steering wheel gear-
shift paddles. The transmission must be in posi- tion D.
The switching times correspond to the previ-
ously active automatic drive program.
The transmission only shifts down automatically
at low engine speeds depending on the respec- tive gear.
In addition to manual mode M, you can also
activate temporary manual drive program
(Y page 114).

RACE drive program (AMG GT S) 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 167). Use the
RACE drive program on a closed-off race circuit.
Drive program RACEis characterised by the fol-
lowing:
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 114).
R the gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (Y page 115). You can follow the
gearshift recommendations at all times and
change gear accordingly using the steering
wheel gearshift paddles. On the basis of the
gearshift recommendation, using the steering wheel gearshift paddles, you can optimise 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 signifi-
cantly increases or decreases.
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 rigid
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. 116

Driving systems
Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change into a lower
gear in good time on long and steep downhill
gradients. Take particular note of this when driv-
ing a laden vehicle. By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and pre-
vents the brakes from overheating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady speed for a prolonged period. You can store anyroad speed above 30 km/h.

The LIM indicator lamp on the cruise control
lever indicates which system you have selected:
R LIM indicator lamp off: cruise control is
selected.
R LIM indicator lamp on: variable SPEED-
TRONIC is selected.
When you activate cruise control, the stored
speed is shown in the multifunction display for five seconds. In addition, the
ésymbol
appears in the multifunction display. In the
speedometer, the segments between the stored
speed and the maximum speed light up.

accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again. X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle cruise speed to the
previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving X
If you want to pull away with DISTRONIC
PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you :.
or X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
i The vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi-
cle then brakes automatically. There is a risk
of an accident. Be ready to brake at all times.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS assists a sporty driving style
when you have selected the Sor S+ drive pro-
gram (see the vehicle Owner's Manual). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. When
you select the Cdrive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving at a speed greater than
70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang- ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
