Important safety notes
G
WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin- ity of powerful electrical installations.
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. Vehicles with KEYLESS-GO start function:
do
not keep the SmartKey in the trunk. Otherwise, the SmartKey may not be detected, e.g. when
starting the engine using the Start/Stop button.
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle.
This occurs, for example:
R when starting the engine
R while driving
R when using the trunk lid unlocking sensor
R when the external door handles are touched
R during convenience closing SmartKey functions
0043
0037 Locks the vehicle

0087 0036 Unlocks the vehicle
X To unlock centrally: press the0036button.
If you do not open the vehicle within approx-
imately 40 seconds of unlocking:
R the vehicle is locked again
R the anti-theft alarm system is armed again.
X To lock centrally: press the0037button.
The SmartKey centrally locks and unlocks the
doors, the glove box and the fuel filler flap.
The turn signals flash once when unlocking and three times when locking.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated via the
multimedia system; see the Digital Operator's
Manual.
When the locator lighting is activated via the
multimedia system, it lights up when it is dark 66
SmartKeyOpening and closing

!
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

RACE START
Important safety notes i
RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
RACE START enables optimal acceleration from
a standing start. For this, a suitably high-grip
road surface is required and the vehicle and tires must be in good working order. G
WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
i Observe the safety notes on driving safety
systems (Y page 58).
Be sure to read the safety notes and informa-
tion on ESP ®
(Y page 62).
i Observe the specific service requirements
for racetrack mode operation (Y page 241).
Activation conditions You can activate RACE START under the follow-
ing conditions:
R the doors are closed
R the engine is running and the engine and
transmission are at operating temperature.
This is the case when the oil temperature dis- play in the multifunction display is shown in
white (Y page 170).
R ESP ®
is functioning correctly (Y page 62)
R the steering wheel is in the straight-ahead
position
R the vehicle is stationary and the brake pedal is
depressed sufficiently (left foot)
R the transmission is in position 005B
R drive program S,S+ orRACE is selected
(Y page 116). Activating RACE START (AMG GT S) i
When manual mode (Y
page 123) is active,
the transmission automatically shifts up in
the RACE START drive program. This function supports maximum acceleration with RACE
START. After going through an accelerating
process once from a stationary position, this
function is automatically deactivated.
