Vehicles with KEYLESS-GO are equipped with

button.
The Start/Stop button must be inserted in the
ignition lock and the SmartKey with the
integrated KEYLESS-GO function must be in

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
immediately.
The Start/Stop button can be removed from
the ignition lock. Then, you can insert the
SmartKey into the ignition lock.
