Key

The vehicle's equipment includes two keys with remote control. Each key contains an emergency key element.

The key is configured at the factory to centrally lock and unlock the following:

  • the doors

  • the boot lid

  • the fuel filler flap

  • the glove compartment

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 using a key which has been left in the vehicle

  • release the parking brake

They could thereby endanger themselves and others. Never leave children unsupervised in the vehicle. Always take the key with you when leaving the vehicle, even if you are only leaving it for a short time.

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

  • the fuel filler flap

  • the glove compartment

If you pull on the handle of the boot lid, only the boot lid 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, even if it has been locked. Or they could start the vehicle if a valid KEYLESS GO key is in the vehicle and they press the KEYLESS GO button on the selector lever. They could thereby 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.

If the vehicle has been parked for a long time, you must pull the door handle to activate the KEYLESS GO functions.

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.

Factory settings

  

To unlock centrally: pull the door handle.

 

The turn signals flash once. The locking knobs in the doors pop up. The anti-theft alarm system* is deactivated.

If you do not open either a door or the boot lid after you have unlocked the vehicle, it will automatically relock after approximately 40 seconds.

When a door is opened, the side window on that side opens slightly. When the door is closed, the side window closes again.

The side windows will not open/close if the battery is discharged or if the side windows have iced up. It will then not be possible to close the door. Do not attempt to force the door to close. Otherwise, you could damage the door or the window.

There is a danger of the vehicle being unlocked unintentionally. This could occur if the KEYLESS GO key is within one metre of the vehicle and the door handle is splashed with water. This could also occur when cleaning the door handle.

Locking button on the door handle
  

To lock centrally: press locking button  on the door handle without touching the inside of the handle.

 

The turn signals flash three times. The locking knobs in the doors drop down. The anti-theft alarm system* and the immobiliser are primed.

You can change the setting of the locking system. If you now touch the inside surface of the door handle on the driver's door, you will only unlock the driver's door and the fuel filler flap. This could be useful if you frequently travel on your own.
