2019 MERCEDES-BENZ AMG GT ROADSTER light

!
Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has
reached its operating temperature.
In vehicles with automatic transmission,
engage positions P and R only when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! During a cold start with low engine oil tem-
peratures (below 32 ‡) (0 †), the maximum
engine speed is restricted in order to protect
the engine. To protect the engine and main-
tain smooth engine operation, avoid driving at full throttle when the engine is cold. Key positions
Start/Stop button General notes
All vehicles are equipped with a Start/Stop but-
ton.
The Start/Stop button is located in the center
console and is illuminated when the vehicle is
unlocked.
The SmartKey must be in the vehicle.
Pressing the Start/Stop button several times in succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
If there is a SmartKey in the ignition lock, this
takes precedence over the KEYLESS-GO start
function.
To start the vehicle without actively using the
SmartKey:
R the SmartKey must be in the vehicle
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 67)Do not keep the SmartKey:
R with electronic devices, e.g. a mobile phone
or another SmartKey
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of the Smart-
Key.
If you lock the vehicle with the SmartKey remote control or with KEYLESS-GO, after a short time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will no longer be able to start the engine
with the Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the button
on the driver's door (Y page 72), you can con-
tinue to start the engine with the Start/Stop
button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.
Key positions with the Start/Stop button As soon as the ignition is switched on, all the
indicator lamps in the instrument cluster light
up. Further information on situations where an
indicator lamp either fails to go out after starting the engine or lights up while driving
(Y page 200).
If Start/Stop button 0043has not yet been
pressed, this corresponds to the SmartKey
being removed from the ignition.
X To switch on the power supply: press
Start/Stop button 0043once.
The power supply is switched on. You can now
activate the windshield wipers, for example. If you press Start/Stop button 0043twice in this 110

Shift the transmission to position 005D
(Y page 117).
The transmission position indicator on the
multifunction display shows 005D
(Y page 119).
You can start the engine in transmission posi-
tion 005Dand 005C.
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.
X Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once
(Y page 110).

Starting procedure with the SmartKey X
Turn the SmartKey to position 0049in the igni-
tion lock (Y page 111) and release it as soon
as the engine is running.
If the engine will not start: X Remove the SmartKey from the ignition lock.
X Reinsert the SmartKey into the ignition lock
after a short waiting period. X
Turn the SmartKey to position 0048in the igni-
tion lock (Y page 111).

General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position 003A
or 0046, the vehicle could pull away suddenly.
There is a risk of an accident.
When engaging transmission position 003Aor
0046, 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 73).
It is only possible to shift the transmission from position 005Dto 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 engaged.
Information on the automatic release of the
electric parking brake (Y page 130).
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. 112
