This can affect the functionality of
KEYLESS-GO.
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and a detachable Start/Stop
button.
The Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
SmartKey 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
immediately.
The Start/Stop button can be removed from
the ignition lock. Then, you can insert the
SmartKey into the ignition lock.

You do not have to remove the Start/Stop
button from the ignition lock when you
leave the vehicle. You should, however,
always take the SmartKey with you when
leaving the vehicle. As long as the
SmartKey is in the vehicle:
the vehicle can be started using the
R
Start/Stop button and
electrically powered equipment can be
R
operated.
