When locking the vehicle with the smart key, a mislock can occur if:
One or more of the doors, the bonnet, or the tailgate are not fully closed.
One or more of the doors have failed to lock.
The ignition is switched on.
If any of the above are present, the vehicle does not lock and an audible mislock error warning sounds. The hazard warning lights do not flash and the power-fold mirrors, if enabled, do not fold in. Check that all of the doors, the windows, the bonnet, and the tailgate are closed properly. Make sure the ignition is switched off. Lock the vehicle again. If the mislock persists, consult a retailer/authorised repairer.
Operating the interior or exterior door handles while attempting to unlock, lock, or change the child lock status may cause the security system to ignore any requests.
