The engine cannot be started. Start/Stop button General notes Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and ad etachable Start/Stop but-
ton.
Ac heck which periodically establishes ar adio
connection between the vehicle and the Smart-
Key determines whether av alid SmartKey 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 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.
To start the vehicle without actively using the
SmartKey: R
the Start/Stop button must be inserted in the
ignition lock R

with electronic devices, e.g. am obile phone
or another SmartKey. R
with metallic objects, e.g. coins or metal foil. R
inside metallic objects, e.g. am etal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after as hort 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
