2018 MERCEDES-BENZ AMG GT COUPE transmission

General notes
The catalytic converter is preheated for up to
30 seconds after a cold start. The sound of the
engine may change during this time.

You can start the engine in transmission posi-
tion jand i.
Starting procedure with the Start/Stop
button
The Start/Stop button can be used to start the
vehicle manually without inserting the SmartKey
into the ignition lock. You merely need to carry
the SmartKey on your person. This mode for
starting the engine operates independently of
the ECO start/stop automatic engine start func-
tion.
You can start the engine if a valid SmartKey is in
the vehicle. Switch off the engine and always
take the SmartKey with you when leaving the
vehicle, even if you only leave it for a short time.
Pay attention to the important safety notes.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(Ypage 105).
The engine starts.
Starting procedure with the SmartKey
XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 106) and release it as soon
as the engine is running.
If the engine will not start:
XRemove the SmartKey from the ignition lock.
XReinsert the SmartKey into the ignition lock
after a short waiting period.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 106).
The indicator lamps in the instrument cluster
light up (
Ypage 193).
XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 106) and release it as soon
as the engine is running.
Pulling away
General notes
GWARNING
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 (
Ypage 72).
It is only possible to shift the transmission from
position jto the desired position if:
Rthe engine is running and
Ryou 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 engaged.
Information on the automatic release of the
electric parking brake (
Ypage 125).
Hill start assist
Hill start assist helps you when pulling away
forward 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 to
depress it before the vehicle begins to roll.

GWARNING
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:
Ryou are pulling away on a level road or on a
downhill gradient
Rthe transmission is in position i
Rthe electric parking brake is applied
RESP®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:
Rreduced steering effort and turning circle,
resulting in reduced parking effort.
Rimproved driving stability, e.g. on curves.
Rthe 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
GWARNING
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.
General notes
:ECO start/stop display
If the engine has been switched off automati-
cally by the ECO start/stop function, the è
ECO symbol is shown in the multifunction dis-
play.
The ECO start/stop function is only available in drive program C.
The ECO start/stop function is activated when-
ever you switch on the engine using the Smart-
Key or the Start/Stop button. This is the case if:
Rthe ignition was switched off for more than
four hours or
Rthe ECO start/stop function had been activa-
ted before the engine was switched off

ProblemPossible causes/consequences andMSolutions
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature

Driving and parking

ANeutral
Do not shift the transmission toi
while driving. The automatic trans-
mission could otherwise be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow you to
move the vehicle freely, e.g. to push
it or tow it.
If ESP
®is deactivated or faulty: shift
the transmission to position iif the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch off the engine using the
SmartKey or the Start/Stop button,
the automatic transmission shifts to

!Coasting in neutral imay
cause damage to the drive train.
7Drive
The automatic transmission changes
gear automatically in the automatic
drive programs (
Ypage 117). 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 h. This automatic gear shift-
ing behavior is determined by:
Rthe selected drive program (Ypage 111)
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore 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:
XIn 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.
XEase 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 positionshand k.
The vehicle's transmission management
restricts shifting between transmission posi-
tions hand kto speeds up to a maximum of
5 mph (9 km/h).
To shift back and forth between transmission
positions hand k, move the E-SELECT lever
up and down beyond the pressure point.
