You can start, lock or unlock the vehicle using KEYLESS GO. To do this, you only need carry the 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.
The distance to the vehicle's door handle from which you wish to lock or unlock the vehicle must not be greater than 1 m.
When starting the engine and whilst driving, KEYLESS GO also checks whether a valid key is in the vehicle by periodically establishing radio contact.

If you pull on the handle of the boot lid, only the boot of the vehicle is unlocked.

The vehicle is locked automatically when the ignition is switched on and the wheels begin to turn. There is a risk of being locked out when the vehicle is being pushed or tested on a dynamometer. |

The power closing mechanism pulls the doors* and boot lid into their locks automatically even if they are only partly closed.
|
Risk of accident |
|
Make sure that the doors and boot lid are always fully closed. Otherwise, a door or the boot lid could open during the journey and endanger yourself or others. |
