Lock confirmation
Exterior indication
- The car's hazard warning flashers indicate locking by flashing and retracting the door mirrors1.
- The car's hazard warning flashers indicate unlocking by two flashes and extending the door mirrors1.
All doors, the tailgate and the bonnet must be closed for the car to indicate that it is locked. If locking takes place with just the driver door closed2, locking will take place but the lock indication with hazard warning flashers will only take place when all doors, the tailgate and the bonnet have been closed.
