General notes
Vehicles with KEYLESS-GO are equipped withSmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-ton.
A check which periodically establishes a radioconnection between the vehicle and the Smart-Key determines whether a valid SmartKey is inthe vehicle. This occurs, for example, whenstarting the engine.
When you insert the Start/Stop button into theignition lock, the system needs approximatelytwo seconds recognition time. You can then usethe Start/Stop button.
Pressing the Start/Stop button several times insuccession corresponds to the different Smart-Key positions in the ignition lock. This is only thecase if you are not depressing the brake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted in theignition lock
Rthe SmartKey must be in the vehicle

Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.

Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will no longer be able to start the enginewith the Start/Stop button until the vehicle isunlocked again.
