The power windows standard on both the Fiesta and the Mazda3 have locks to prevent small children from operating them. When the lock on the Fiesta is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Mazda3 prevents the driver from operating the other windows just as it does the other passengers.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Fiesta’s available exterior PIN entry system. The Mazda3 doesn’t offer an exterior PIN entry system.
The Fiesta (except S)’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Mazda3’s navigation system doesn’t offer real-time traffic updates.
