2016 MERCEDES-BENZ AMG GT ROADSTER Owners Manual

!
Do not warm up the engine when the vehicle
is stationary. Drive off immediately. Avoid
high engine speeds and driving at full throttle
until the engine has reached its operating
temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta- tionary.
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 0 †), the maximum engine
speed is restricted in order to protect the
engine. To protect the engine and maintain
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 on the centre
console and is illuminated when the vehicle is
unlocked.
The key must be in the vehicle.
Pressing the Start/Stop button several times in
succession corresponds to the different 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 key
determines whether a valid key is in the vehicle. This occurs, for example, when starting the
engine.
If there is a key in the ignition lock, this takes
precedence over the KEYLESS-GO start func-
tion.
To start the vehicle without actively using the
key:
R the key must be in the vehicle
R the vehicle must not be locked with the key or
KEYLESS-GO (Y page 64) Do not keep the key:
R
with electronic devices, e.g. a mobile phone
or another key
R with metallic objects, e.g. coins or metal film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's 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 not 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 70), 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 When you switch on the ignition, all of the indi-
cator lamps in the instrument cluster light up.
Further information on situations where an indi-
cator lamp either fails to go out after starting the engine or lights up while driving (Y page 196).
If Start/Stop button :has not yet been
pressed, this corresponds to the key being
removed from the ignition. 102

Important safety notes G
WARNING
If children are left unsupervised in the vehicle, they can:
R open doors and endanger other persons or
road users
R climb out and be injured by the traffic
R operate vehicle equipment and, for exam-
ple, trap themselves.
Children could also set the vehicle in motion, for example by:
R releasing the parking brake

park position P
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. Always
keep the key out of reach of children. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system. Driving

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

Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When the vehicle pulls away again, the engine
starts automatically. The ECO start/stop func-
tion thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
