KEYLESS-GO
General information
Vehicles with KEYLESS-GO are equipped with a SmartKey featuring an integrated KEYLESSGO function and a detachable Start/Stop button.
The Start/Stop button must be inserted into 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. However, you should 
always take the SmartKey with you when 
leaving the vehicle. The vehicle can be 
started with the Start/Stop button if the 
SmartKey is in the vehicle.
