!
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.
!
Mercedes-AMG vehicles: at low engine oil
temperatures (below +20 †), 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.

If the key does not belong to the vehicle, it
can still be turned in the ignition lock. How-
ever, the ignition will not be switched on. The
engine cannot be started.
KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
key featuring an integrated KEYLESS-GO func-
tion and a detachable Start/Stop button.
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.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
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.
To start the vehicle without actively using the
key:
R
the Start/Stop button must be inserted in the
ignition lock
R
the key must be in the vehicle
R
the vehicle must not be locked with the key or
KEYLESS-GO (
Y
page 82)
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 function of the key with KEY-
LESS-GO.
Do not keep the KEYLESS-GO key in the tem-
perature-controlled cup holder (
Y
page 321).
Otherwise, the KEYLESS-GO or KEYLESS-GO
Start function key will not be detected.
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 front door (
Y
page 88), you can continue
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.
