WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.

WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R
overheat and cause a fire
R
lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!
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.
Observe the important safety notes for PLUG-IN
HYBRID vehicles (

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.
