The power windows standard on both the Fusion and the ES Series have locks to prevent small children from operating them. When the lock on the Fusion is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The ES Series 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 Fusion SE/Titanium/Sport/Platinum’s exterior keypad. The ES Series doesn’t offer an exterior keypad entry system.
The Fusion’s power mirror controls are mounted on the armrest for easy access. The ES Series’ power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.
The Fusion (except S) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The ES Series doesn’t offer a house-current electrical outlet.
The Fusion (except S)’s optional Enhanced Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ES Series doesn’t offer an automated parking system.
