KEYLESS GO key*
The optional equipment supplied with your vehicle includes two KEYLESS GO keys. KEYLESS GO allows you to lock/unlock and start the vehicle simply by carrying the KEYLESS GO key with you. When you touch the surface of the sensors on the vehicle's door handles, KEYLESS GO establishes a radio connection between the vehicle and the key.
When you touch the inner surface of the door handle, the vehicle is unlocked centrally if the factory settings have not been changed:
-
the doors
-
the boot lid/tailgate
-
the fuel filler flap
If you press the button in the handle of the boot lid/tailgate, only the boot/luggage compartment of your vehicle is unlocked.
When starting the engine and whilst driving, KEYLESS GO also checks whether a valid KEYLESS GO key is in the vehicle by periodically establishing radio contact.
| Risk of accident |
|
If children are left unsupervised in the vehicle, they could:
-
open a door from the inside at any time, even if it has been locked
-
start the vehicle if a valid KEYLESS GO key is in the vehicle and they press the KEYLESS GO button on the ignition lock
-
release the parking brake
They could endanger themselves and others. Never leave children unsupervised in the vehicle. Switch off the engine and take the KEYLESS GO key with you, even if you are only leaving the vehicle for a short time.

Important notes
-
If the KEYLESS GO key is removed from the vehicle (e.g. in luggage or an article of clothing), it will no longer be possible to lock or start the vehicle.
-
If the KEYLESS GO key is removed from the vehicle while the engine is running, e.g. if the front passenger leaves the vehicle with the KEYLESS GO key, the following message will appear in the multi-function display as you pull away: Key not detected.
-
If the KEYLESS GO key is in the vehicle, the vehicle can be started at any time. If you have left the KEYLESS GO key in the vehicle, the following message will appear in the multi-function display when you lock the vehicle: Key still in vehicle.
