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 tailgate

  • the fuel filler flap

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 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.
