Important safety notes
GWARNING
It is dangerous to shift the transmission out
of park position P or neutral position N if the
engine is running at anything more than idling
speed. If you do not depress the brake pedal
with force, the vehicle may accelerate
forwards or backwards. This could cause you
to lose control of your vehicle and cause a
collision. Only shift the transmission into the
drive position when you are firmly depressing
the brake pedal.

Driving tips
Double-clutch function
When shifting down, the double-clutch
function is active regardless of the currently
selected drive program. The double-clutch
function reduces the load change reaction on
the drive axle. The sound generated by the
double-clutch function depends on the drive
program selected.
Kickdown
i Kickdown is not available in manual drive
program M.
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond the
pressure point.
Depending on the selected drive program,
the transmission shifts to the lowest gear
allowing ideal acceleration.
Working on the vehicle
GWARNING
When working on the vehicle, engage the
electric parking brake and shift the automatic
transmission into park position P. Otherwise,
the vehicle could roll away and cause an
accident and/or serious injuries.

Steering wheel paddle shifters
In transmission position D, you can use the
steering wheel paddle shifters to restrict or
derestrict the transmission shift range. One
of the automatic drive programs, C, S or S+,
must be selected in order to do so.
In manual drive program M, you need to
change gear yourself using the steering wheel
paddle shifters. At low engine speeds, the
transmission shifts down automatically.

RACE START
RACE START facilitates optimum vehicle
acceleration from a standstill if the road
surface offers suitable grip.
GWARNING
RACE START is only available when SPORT
handling mode is activated. SPORT handling
mode will only be able to stabilize the vehicle
to a limited degree if the vehicle starts to skid
or a wheel starts to spin. The vehicle is
therefore harder to control at the threshold
range. You could lose control of the vehicle
and cause an accident.
RACE START must only be used on closed off
circuits. Always adapt your driving style to suit
the prevailing road and weather conditions.
Conditions for activation
You can activate RACE START if:
R the doors are closed.
R the engine is running and the engine and
transmission are at operating temperature
( Y page 160).

been driven.
Automatic drive program
Drive program C is characterized by the
following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the transmission shifting up sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity; this improves driving
stability on slippery road surfaces, for
example
R the transmission shifting up sooner; this
results in the vehicle being driven at lower
engine speeds and the wheels being less
likely to spin
Drive programs S and S+ are characterized
by the following:
R sporty engine and transmission settings
R the transmission shifting up later and
shifting down dynamically
124AMG SPEEDSHIFT DCT 7-speed sports transmissionDriving and parking

Ras a result of the later transmission
upshifts, the fuel consumption may be
higher
R if a period of dynamic driving is followed by
an extended phase with a constant
accelerator pedal position, the vehicle
shifts up to a higher gear. This optimizes
fuel consumption
If a gentle driving style is adopted in
automatic drive programs C/S/S+, the drive
program settings are adjusted to optimize
fuel consumption. Depending on the
operating conditions, the transmission shifts
to a higher gear.
Shift ranges
Introduction
In certain driving situations, it is
recommended to restrict the shift range. The
set shift range appears in the instrument
cluster's multifunction display ( Y page 121).
The transmission only shifts to the gear
displayed in the instrument cluster.
When the maximum engine speed is reached,
the transmission shifts up a gear in the
automatic programs C/S/S+. Gear
restriction is correspondingly increased by
one gear.
Driving situation=The braking effect of the engine can
be utilized in this position5To use the braking effect of the
engine on downhill gradients and

GWARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
XPull the left steering wheel paddle (DOWN).
The transmission shifts down one gear and
restricts the shift range to this gear.
If the engine speed in manual drive
program M is too high, it is not possible to
shift down. The two red segments in the
instrument cluster flash if you pull the left-
hand steering wheel paddle shifter (DOWN)
( Y page 126).
Clearing the shift range restriction
XPull the right-hand steering wheel paddle
shifter (UP) until the number for the gear
disappears from the multifunction display.
or
XUse the E-SELECT lever to shift the
transmission to position D.
The transmission shifts from the current
shift range directly to D.
Selecting the ideal shift range
XPull the left-hand steering wheel paddle
shifter repeatedly until the function is
activated.
Depending on the selected drive program,
the transmission shifts to a gear which
allows ideal acceleration and deceleration.
To do this, the transmission shifts down
one or more gears.AMG SPEEDSHIFT DCT 7-speed sports transmission125Driving and parkingZ

Manual drive program
In manual drive program M, you need to
change gear yourself using the steering wheel
paddle shifters ( Y page 123). The
transmission only shifts down automatically
at low engine speeds depending on the
respective gear.
! In manual drive program M, the
transmission 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 and observe
the upshift indicator. There is otherwise a
risk of engine damage.XTo activate the manual drive program:
turn the drive program selector switch until
M appears in the instrument cluster's
multifunction display.
M lights up in red on the drive program
selector switch.XTo deactivate the manual drive
program: turn the drive program selector
switch and select another drive program.
Upshift indicator
The upshift indicator is a four-stage display
designed to assist you in sporty driving.
The upshift indicator allows you to recognize
the ideal shift point for dynamic acceleration.
White segments : and yellow segment ;
light up in succession from left to right.
When red segments = light up and the "up"
message appears in the multifunction
display, the ideal shift point has been
reached:XShift up using the right-hand steering wheel
paddle shifter (UP) as quickly as possible.
The vehicle shifts up to the next gear.
i If you continue to increase the engine
speed without shifting up in time, the fuel
supply is shut off to protect the engine. This
results in abruptly reduced acceleration.
Display for downshift override
If the engine speed is too high, you cannot
shift down with the left steering wheel paddle
shifter. If you then pull the left steering wheel
paddle shifter, both red segments = light up
briefly.

Refueling
Important safety notes
GWARNING
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to your
health.
GWARNING
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury.
! Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of
diesel will cause damage to the injection
system. Damage caused by adding diesel
is not covered by the Limited Warranty.
! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.
Gasoline (EN 228)
Fuel grade
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.
i Only refuel with premium-grade unleaded
gasoline with a specified minimum octane
number of 91 (average value of 96 RON/
86 MON).
You will usually find information about the
fuel grade on the pump. If you cannot find
the label on the pump, ask the staff for
assistance.
