usage of the pedals.
G 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.
G WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
overheat and cause a fire
R
lose its hold function.
R
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 vehi-
cle 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 stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.
! Mercedes-AMG vehicles: avoid full-load
operation and engine speeds greater than
5000 rpm when the engine is cold. This will
help to protect the engine and maintain
smooth engine operation.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO
function 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 vehi-
cle. This occurs, for example, when starting
the engine.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
